New Li-ion Battery Evaluation Research Based on Thermal Property and Heat Generation Behavior of Battery  

Science Journals Connector (OSTI)

We do a new Li-ion battery evaluation research on the effects of cell resistance and polarization on the energy loss in batteries based on thermal property and heat generation behavior of battery. Series of 18650 cells with different capacities and electrode materials are evaluated by measuring input and output energy which change with charge-discharge time and current. Based on the results of these tests, we build a model of energy loss in cells' charge-discharge process, which include Joule heat and polarization heat impact factors. It was reported that Joule heat was caused by cell resistance, which included DC-resistance and reaction resistance, and reaction resistance could not be easily obtained through routine test method. Using this new method, we can get the total resistance R and the polarization parameter ?. The relationship between R, ?, and temperature is also investigated in order to build a general model for series of different Li-ion batteries, and the research can be used in the performance evaluation, state of charge prediction and the measuring of consistency of the batteries.

Thermal Batteries for Electric Vehicles  

SciTech Connect (OSTI)

HEATS Project: UT Austin will demonstrate a high-energy density and low-cost thermal storage system that will provide efficient cabin heating and cooling for EVs. Compared to existing HVAC systems powered by electric batteries in EVs, the innovative hot-and-cold thermal batteries-based technology is expected to decrease the manufacturing cost and increase the driving range of next-generation EVs. These thermal batteries can be charged with off-peak electric power together with the electric batteries. Based on innovations in composite materials offering twice the energy density of ice and 10 times the thermal conductivity of water, these thermal batteries are expected to achieve a comparable energy density at 25% of the cost of electric batteries. Moreover, because UT Austin’s thermal energy storage systems are modular, they may be incorporated into the heating and cooling systems in buildings, providing further energy efficiencies and positively impacting the emissions of current building heating/cooling systems.

Piezoelectric, solar and thermal energy harvesting for hybrid low-power generator systems with thin-film batteries  

Science Journals Connector (OSTI)

The harvesting of ambient energy to power small electronic components has received tremendous attention over the last decade. The research goal in this field is to enable self-powered electronic components for use particularly in wireless sensing and measurement applications. Thermal energy due to temperature gradients, solar energy and ambient vibrations constitute some of the major sources of energy that can be harvested. Researchers have presented several papers focusing on each of these topics separately. This paper aims to develop a hybrid power generator and storage system using these three sources of energy in order to improve both structural multifunctionality and system-level robustness in energy harvesting. A multilayer structure with flexible solar, piezoceramic, thin-film battery and metallic substructure layers is developed (with the overhang dimensions of 93 mm ? 25 mm ? 1.5 mm in cantilevered configuration). Thermal energy is also used for charging the thin-film battery layers using a 30.5 mm ? 33 mm ? 4.1 mm generator. Performance results are presented for charging and discharging of the thin-film battery layers using each one of the harvesting methods. It is shown based on the extrapolation of a set of measurements that 1 mA h of a thin-film battery can be charged in 20 min using solar energy (for a solar irradiance level of 223 W m?2), in 40 min using thermal energy (for a temperature difference of 31 °C) and in 8 h using vibrational energy (for a harmonic base acceleration input of 0.5g at 56.4 Hz).

Thermal analysis and two-directional air flow thermal management for lithium-ion battery pack  

Science Journals Connector (OSTI)

Abstract Thermal management is a routine but crucial strategy to ensure thermal stability and long-term durability of the lithium-ion batteries. An air-flow-integrated thermal management system is designed in the present study to dissipate heat generation and uniformize the distribution of temperature in the lithium-ion batteries. The system contains of two types of air ducts with independent intake channels and fans. One is to cool the batteries through the regular channel, and the other minimizes the heat accumulations in the middle pack of batteries through jet cooling. A three-dimensional anisotropic heat transfer model is developed to describe the thermal behavior of the lithium-ion batteries with the integration of heat generation theory, and validated through both simulations and experiments. Moreover, the simulations and experiments show that the maximum temperature can be decreased to 33.1 °C through the new thermal management system in comparison with 42.3 °C through the traditional ones, and temperature uniformity of the lithium-ion battery packs is enhanced, significantly.

Simplified Heat Generation Model for Lithium ion battery used in Electric Vehicle  

Science Journals Connector (OSTI)

It is known that temperature variations inside a battery may greatly affect its performance, life, and reliability. In an effort to gain a better understanding of the heat generation in Lithium ion batteries, a simple heat generation models were constructed in order to predict the thermal behaviour of a battery pack. The Lithium ion battery presents in this paper is Lithium Iron Phosphate (LiFePO4). The results show that the model can be viewed as an acceptable approximation for the variation of the battery pack temperature at a continuous discharge current from data provided by the manufacturer and literature.

The feasibility of a small, fast-rise thermal battery for non-spinning munitions applications was examined by studying the response of conventional thermal cells to impact (mechanical) energy to simulate a setback environment. This is an extension of earlier work that demonstrated that shock activation could be used to produce power from a conventional thermal-battery cell. The results of tests with both single and multiple cells are presented, along with data for a 5-cell miniature (5-mm diameter) thermal battery. The issues needing to be resolved before such a device can become a commercial reality are also discussed.

Experimental performances of a battery thermal management system using a phase change material  

Science Journals Connector (OSTI)

Abstract Li-ion batteries are leading candidates for mobility because electric vehicles (EV) are an environmentally friendly mean of transport. With age, Li-ion cells show a more resistive behavior leading to extra heat generation. Another kind of problem called thermal runway arises when the cell is too hot, what happens in case of overcharge or short circuit. In order to evaluate the effect of these defects at the whole battery scale, an air-cooled battery module was built and tested, using electrical heaters instead of real cells for safety reasons. A battery thermal management system based on a phase change material is developed in that study. This passive system is coupled with an active liquid cooling system in order to initialize the battery temperature at the melting of the PCM. This initialization, or PCM solidification, can be performed during a charge for example, in other words when the energy from the network is available.

Generating random thermal momenta  

E-Print Network [OSTI]

Generation of random thermal particle momenta is a basic task in many problems, such as microscopic studies of equilibrium and transport properties of systems, or the conversion of a fluid to particles. In heavy-ion physics, the (in)efficiency of the algorithm matters particularly in hybrid hydrodynamics + hadronic transport calculations. With popular software packages, such as UrQMD 3.3p1 or THERMINATOR, it can still take ten hours to generate particles for a single Pb+Pb "event" at the LHC from fluid dynamics output. Below I describe reasonably efficient simple algorithms using the MPC package, which should help speed momentum generation up by at least one order of magnitude. It is likely that this wheel has been reinvented many times instead of reuse, so there may very well exist older and/or better algorithms that I am not aware of (MPC has been around only since 2000). The main goal here is to encourage practitioners to use available efficient routines, and offer a few practical solutions.

Evaluating the ignition sensitivity of thermal battery heat pellets  

SciTech Connect (OSTI)

Thermal batteries are activated by the ignition of heat pellets. If the heat pellets are not sensitive enough to the ignition stimulus, the thermal battery will not activate, resulting in a dud. Thus, to assure reliable thermal batteries, it is important to demonstrate that the pellets have satisfactory ignition sensitivity by testing a number of specimens. There are a number of statistical methods for evaluating the sensitivity of a device to some stimulus. Generally, these methods are applicable to the situation in which a single test is destructive to the specimen being tested, independent of the outcome of the test. In the case of thermal battery heat pellets, however, tests that result in a nonresponse do not totally degrade the specimen. This peculiarity provides opportunities to efficiently evaluate the ignition sensitivity of heat pellets. In this paper, a simple strategy for evaluating heat pellet ignition sensitivity (including experimental design and data analysis) is described. The relatively good asymptotic and small-sample efficiencies of this strategy are demonstrated.

Novel thermal management system design methodology for power lithium-ion battery  

Science Journals Connector (OSTI)

Abstract Battery packs conformed by large format lithium-ion cells are increasingly being adopted in hybrid and pure electric vehicles in order to use the energy more efficiently and for a better environmental performance. Safety and cycle life are two of the main concerns regarding this technology, which are closely related to the cell's operating behavior and temperature asymmetries in the system. Therefore, the temperature of the cells in battery packs needs to be controlled by thermal management systems (TMSs). In the present paper an improved design methodology for developing \\{TMSs\\} is proposed. This methodology involves the development of different mathematical models for heat generation, transmission, and dissipation and their coupling and integration in the battery pack product design methodology in order to improve the overall safety and performance. The methodology is validated by comparing simulation results with laboratory measurements on a single module of the battery pack designed at IK4-IKERLAN for a traction application. The maximum difference between model predictions and experimental temperature data is 2 °C. The models developed have shown potential for use in battery thermal management studies for EV/HEV applications since they allow for scalability with accuracy and reasonable simulation time.

Fluoride based cathodes and electrolytes for high energy thermal batteries  

SciTech Connect (OSTI)

A research and development program is being conducted at the Saft Advanced Technologies Division in Hunt Valley, MD to double the energy density of a thermal battery. A study of high voltage cathodes to replace iron disulfide is in progress. Single cells are being studied with a lithium anode and either a copper(II) fluoride, silver(II) fluoride, or iron(III) fluoride cathode. Due to the high reactivity of these cathodes, conventional alkali metal chloride and bromide salt electrolytes must be replaced by alkali metal fluoride electrolytes. Parametric studies using design-of-experiments matrices will be performed so that the best cathode for an improved battery design can be selected. Titanium hardware for the design will provide a higher strength to weight ratio with lower emissivity than conventional stainless steel. The battery will consist of two power sections. The goals are battery activation in less than 0.2 s, 88 Wh/kg, 1,385 W/kg, and 179 Wh/L over an environmental temperature range of {minus}40 C to +70 C.

Analysis of the thermal behavior of a LiFePO4 battery cell  

Science Journals Connector (OSTI)

This paper presents theory, experiments and numerical modeling results for the electrothermal analysis of Lithium Iron Phosphate (LiFePO4) battery cells. Thermal management of batteries is important for several reasons including thermal runaway and maintaining battery operating time. A battery pack is comprised of battery cells which are stacked together without cooling surfaces except for the pack outer surface. The central cells in the pack are therefore exposed to the risk of overheating. A model for a single specific commercial LiFePO4 battery cell is presented together with preliminary experiments and results for determination of heating sources during charging and discharging. Based on the experimental results we extract model parameters for use in the model. The experiments lead to relations for the cell surface temperature and the lump temperature of the cell. A reasonable agreement between experiments and the model is found and suggestions for further work is indicated.

Thermo-electrochemical analysis of lithium ion batteries for space applications using Thermal Desktop  

Science Journals Connector (OSTI)

Abstract Lithium-ion batteries (LIBs) are replacing the Nickel–Hydrogen batteries used on the International Space Station (ISS). Knowing that LIB efficiency and survivability are greatly influenced by temperature, this study focuses on the thermo-electrochemical analysis of \\{LIBs\\} in space orbit. Current finite element modeling software allows for advanced simulation of the thermo-electrochemical processes; however the heat transfer simulation capabilities of said software suites do not allow for the extreme complexities of orbital-space environments like those experienced by the ISS. In this study, we have coupled the existing thermo-electrochemical models representing heat generation in \\{LIBs\\} during discharge cycles with specialized orbital-thermal software, Thermal Desktop (TD). Our model's parameters were obtained from a previous thermo-electrochemical model of a 185 Amp-Hour (Ah) LIB with 1–3 C (C) discharge cycles for both forced and natural convection environments at 300 K. Our TD model successfully simulates the temperature vs. depth-of-discharge (DOD) profiles and temperature ranges for all discharge and convection variations with minimal deviation through the programming of FORTRAN logic representing each variable as a function of relationship to DOD. Multiple parametrics were considered in a second and third set of cases whose results display vital data in advancing our understanding of accurate thermal modeling of LIBs.

Experimental investigation of battery thermal management system for electric vehicle based on paraffin/copper foam  

Science Journals Connector (OSTI)

Abstract To enhance the heat transfer of phase change material in battery thermal management system for electric vehicle, a battery thermal management system by using paraffin/copper foam was designed and experimentally investigated in this paper. The thermal performances of the system such as temperature reduction and distribution are discussed in detail. The results showed that the local temperature difference in both a single cell and battery module were increased with the increase of discharge current, and obvious fluctuations of local temperature difference can be observed when the electric vehicle is in road operating state. When the battery is discharging at constant current, the maximum temperature and local temperature difference of the battery module with paraffin/copper foam was lower than 45 °C and 5 °C, respectively. After the battery thermal management system was assembled in electric vehicle, the maximum temperature and local temperature difference in road operating state was lower than 40 °C and 3 °C, respectively. The experimental results demonstrated that paraffin/copper foam coupled battery thermal management presented an excellent cooling performance.

Dynamic electro-thermal modeling of all-vanadium redox flow battery with forced cooling strategies  

Science Journals Connector (OSTI)

Abstract The present study focuses on the dynamic electro-thermal modeling for the all-vanadium redox flow battery (VRB) with forced cooling strategies. The Foster network is adopted to dynamically model the heat dissipation of VRB with heat exchangers. The parameters of Foster network are extracted by fitting the step response of it to the results of linearized CFD model. Then a complete electro-thermal model is proposed by coupling the heat generation model, Foster network and electrical model. Results show that the established model has nearly the same accuracy with the nonlinear CFD model in electrolyte temperature prediction but drastically improves the computational efficiency. The modeled terminal voltage is also benchmarked with the experimental data under different current densities. The electrolyte temperature is found to be significantly influenced by the flow rate of coolant. As compared, although the electrolyte flow rate has unremarkable impact on electrolyte temperature, its effect on system pressure drop and battery efficiency is significant. Increasing the electrolyte flow rate improves the coulombic efficiency, voltage efficiency and energy efficiency simultaneously but at the expense of higher pump power demanded. An optimal flow rate exists for each operating condition to maximize the system efficiency.

Shortcut computation for the thermal management of a large air-cooled battery pack  

Science Journals Connector (OSTI)

Abstract Thermal management is crucial to maintain the performance of large battery packs in electric vehicles. To this end, we present herein a shortcut computational method to rapidly estimate the flow and temperature profiles in a parallel airflow-cooled large battery pack with wedge-shaped plenums for airflow distribution. The method couples a flow resistance network model with a transient heat transfer model to calculate the temperature distribution in a battery pack as influenced by the airflows within and among battery modules in the pack. The effects of the plate angle of the plenums, the minimal plenum width and the battery unit spacing on the airflow and temperature distributions are presented. Additionally, an example of collective parameter adjustment for acceptable temperature uniformity of a battery pack subjected to total volume constraint is given.

Differential thermal voltammetry for tracking of degradation in lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract Monitoring of lithium-ion batteries is of critical importance in electric vehicle applications in order to manage the operational condition of the cells. Measurements on a vehicle often involve current, voltage and temperature which enable in-situ diagnostic techniques. This paper presents a novel diagnostic technique, termed differential thermal voltammetry, which is capable of monitoring the state of the battery using voltage and temperature measurements in galvanostatic operating modes. This tracks battery degradation through phase transitions, and the resulting entropic heat, occurring in the electrodes. Experiments to monitor battery degradation using the new technique are compared with a pseudo-2D cell model. Results show that the differential thermal voltammetry technique provides information comparable to that of slow rate cyclic voltammetry at shorter timescale and with load conditions easier to replicate in a vehicle.

Investigation of power battery thermal management by using mini-channel cold plate  

Science Journals Connector (OSTI)

Abstract In order to guarantee the safety and extend the cycle life of Li-ion power batteries within electric vehicles, a mini-channel cold plate-based battery thermal management system is designed to cool a rectangular Li-ion battery. A three-dimensional thermal model of the cooling system was established and the effects of number of channels, flow direction, inlet mass flow rate and ambient temperature on temperature rise and distribution of the battery during the discharge process were investigated. The results suggest that the maximum temperature of the battery decreases with increases in the number of channels and inlet mass flow rate. The effect of flow direction on cooling performance was smaller after mass flow rate increased. The cooling performance improved with the increase of inlet mass flow rate but the increasing trend became smaller, and the mass flow rate as 5 × 10?4 kg s?1 was optimal. The simulation results will be useful for the design of mini-channel cold plate-based battery thermal management system.

Characterization of penetration induced thermal runaway propagation process within a large format lithium ion battery module  

Science Journals Connector (OSTI)

Abstract This paper investigates the mechanisms of penetration induced thermal runaway (TR) propagation process within a large format lithium ion battery pack. A 6-battery module is built with 47 thermocouples installed at critical positions to record the temperature profiles. The first battery of the module is penetrated to trigger a TR propagation process. The temperature responses, the voltage responses and the heat transfer through different paths are analyzed and discussed to characterize the underlying physical behavior. The temperature responses show that: 1) Compared with the results of TR tests using accelerating rate calorimetry (ARC) with uniform heating, a lower onset temperature and a shorter TR triggering time are observed in a penetration induced TR propagation test due to side heating. 2) The maximum temperature difference within a battery can be as high as 791.8 °C in a penetration induced TR propagation test. The voltage responses have a 5-stage feature, indicating that the TR happens in sequence for the two pouch cells packed inside a battery. The heat transfer analysis shows that: 1) 12% of the total heat released in TR of a battery is enough to trigger the adjacent battery to TR. 2) The heat transferred through the pole connector is only about 1/10 of that through the battery shell. 3) The fire has little influence on the TR propagation, but may cause significant damage on the accessories located above the battery. The results can enhance our understandings of the mechanisms of TR propagation, and provide important guidelines in pack design for large format lithium ion battery.

Numerical investigation of thermal behaviors in lithium-ion battery stack discharge  

Science Journals Connector (OSTI)

Abstract Thermal management is critically important to maintain the performance and prolong the lifetime of a lithium-ion (Li-ion) battery. In this paper, a two-dimensional and transient model has been developed for the thermal management of a 20-flat-plate-battery stack, followed by comprehensive numerical simulations to study the influences of ambient temperature, Reynolds number, and discharge rate on the temperature distribution in the stack with different cooling materials. The simulation results indicate that liquid cooling is generally more effective in reducing temperature compared to phase-change material, while the latter can lead to more homogeneous temperature distribution. Fast and deep discharge should be avoided, which generally yields high temperature beyond the acceptable range regardless of cooling materials. At low or even subzero ambient temperatures, air cooling is preferred over liquid cooling because heat needs to be retained rather than removed. Such difference becomes small when the ambient temperature increases to a mild level. The effects of Reynolds number are apparent in liquid cooling but negligible in air cooling. Choosing appropriate cooling material and strategy is particularly important in low ambient temperature and fast discharge cases. These findings improve the understanding of battery stack thermal behaviors and provide the general guidelines for thermal management system. The present model can also be used in developing control system to optimize battery stack thermal behaviors.

Thermal management of batteries using a Variable-Conductance Insulation (VCI) enclosure  

SciTech Connect (OSTI)

Proper thermal management is important for optimum performance and durability of most electric-vehicle batteries. For high-temperature cells such as sodium/sulphur, a very efficient and responsive thermal control system is essential. Heat must be removed during exothermic periods and retained when the batteries are not in use. Current thermal management approaches rely on passive insulation enclosures with active cooling loops that penetrate the enclosure. This paper presents the design, analysis, and testing of an enclosure with variable conductance insulation (VCI). VCI uses a hydride with an integral electric resistance heater to expel and retrieve a small amount of hydrogen gas into a vacuum space. By controlling the amount of hydrogen gas, the thermal conductance can be varied by more than 100:1, enabling the cooling loop (cold plate) to be mounted on the enclosure exterior. By not penetrating the battery enclosure, the cooling system is simpler and more reliable. Also, heat can be retained more effectively when desired. For high temperatures, radiation shields within the vacuum space are required. Ceramic spacers are used to maintain separation of the steel enclosure materials against atmospheric loading. Ceramic-to-ceramic thermal contact resistance within the spacer assembly minimizes thermal conductance. Two full-scale (0.8-m {times} 0.9-m {times} 0.3-m) prototypes were designed, built, and tested under high-temperature 200{degrees}-350{degrees}C battery conditions. With an internal temperature of 330{degrees}C (and 20{degrees}C ambient), the measured total-enclosure minimum heat loss was 80 watts (excluding wire pass-through losses). The maximum heat rejection was 4100 watts. The insulation can be switched from minimum to maximum conductance (hydrogen pressure from 2.0 {times} 10{sup -3} to 8 torr) in 3 minutes. Switching from maximum to minimum conductance was longer (16 minutes), but still satisfactory because of the large thermal mass of the battery.

PV output smoothing using a battery and natural gas engine-generator.  

SciTech Connect (OSTI)

In some situations involving weak grids or high penetration scenarios, the variability of photovoltaic systems can affect the local electrical grid. In order to mitigate destabilizing effects of power fluctuations, an energy storage device or other controllable generation or load can be used. This paper describes the development of a controller for coordinated operation of a small gas engine-generator set (genset) and a battery for smoothing PV plant output. There are a number of benefits derived from using a traditional generation resource in combination with the battery; the variability of the photovoltaic system can be reduced to a specific level with a smaller battery and Power Conditioning System (PCS) and the lifetime of the battery can be extended. The controller was designed specifically for a PV/energy storage project (Prosperity) and a gas engine-generator (Mesa Del Sol) currently operating on the same feeder in Albuquerque, New Mexico. A number of smoothing simulations of the Prosperity PV were conducted using power data collected from the site. By adjusting the control parameters, tradeoffs between battery use and ramp rates could be tuned. A cost function was created to optimize the control in order to balance, in this example, the need to have low ramp rates with reducing battery size and operation. Simulations were performed for cases with only a genset or battery, and with and without coordinated control between the genset and battery, e.g., without the communication link between sites or during a communication failure. The degree of smoothing without coordinated control did not change significantly because the battery dominated the smoothing response. It is anticipated that this work will be followed by a field demonstration in the near future.

Qualitative thermal characterization and cooling of lithium batteries for electric vehicles  

Science Journals Connector (OSTI)

The paper deals with the cooling of batteries. The first step was the thermal characterization of a single cell of the module, which consists in the detection of the thermal field by means of thermographic tests during electric charging and discharging. The purpose was to identify possible critical hot points and to evaluate the cooling demand during the normal operation of an electric car. After that, a study on the optimal configuration to obtain the flattening of the temperature profile and to avoid hot points was executed. An experimental plant for cooling capacity evaluation of the batteries, using air as cooling fluid, was realized in our laboratory in ENEA Casaccia. The plant is designed to allow testing at different flow rate and temperatures of the cooling air, useful for the assessment of operative thermal limits in different working conditions. Another experimental facility was built to evaluate the thermal behaviour changes with water as cooling fluid. Experimental tests were carried out on the LiFePO4 batteries, under different electric working conditions using the two loops. In the future, different type of batteries will be tested and the influence of various parameters on the heat transfer will be assessed for possible optimal operative solutions.

Evaluation of distributed building thermal energy storage in conjunction with wind and solar electric power generation  

Science Journals Connector (OSTI)

Abstract Energy storage is often seen as necessary for the electric utility systems with large amounts of solar or wind power generation to compensate for the inability to schedule these facilities to match power demand. This study looks at the potential to use building thermal energy storage as a load shifting technology rather than traditional electric energy storage. Analyses are conducted using hourly electric load, temperature, wind speed, and solar radiation data for a 5-state central U.S. region in conjunction with simple computer simulations and economic models to evaluate the economic benefit of distributed building thermal energy storage (TES). The value of the TES is investigated as wind and solar power generation penetration increases. In addition, building side and smart grid enabled utility side storage management strategies are explored and compared. For a relative point of comparison, batteries are simulated and compared to TES. It is found that cooling TES value remains approximately constant as wind penetration increases, but generally decreases with increasing solar penetration. It is also clearly shown that the storage management strategy is vitally important to the economic value of TES; utility side operating methods perform with at least 75% greater value as compared to building side management strategies. In addition, TES compares fairly well against batteries, obtaining nearly 90% of the battery value in the base case; this result is significant considering TES can only impact building thermal loads, whereas batteries can impact any electrical load. Surprisingly, the value of energy storage does not increase substantially with increased wind and solar penetration and in some cases it decreases. This result is true for both TES and batteries and suggests that the tie between load shifting energy storage and renewable electric power generation may not be nearly as strong as typically thought.

Prediction of thermal behaviors of an air-cooled lithium-ion battery system for hybrid electric vehicles  

Science Journals Connector (OSTI)

Abstract Thermal management has been one of the major issues in developing a lithium-ion (Li-ion) hybrid electric vehicle (HEV) battery system since the Li-ion battery is vulnerable to excessive heat load under abnormal or severe operational conditions. In this work, in order to design a suitable thermal management system, a simple modeling methodology describing thermal behavior of an air-cooled Li-ion battery system was proposed from vehicle components designer's point of view. A proposed mathematical model was constructed based on the battery's electrical and mechanical properties. Also, validation test results for the Li-ion battery system were presented. A pulse current duty and an adjusted US06 current cycle for a two-mode HEV system were used to validate the accuracy of the model prediction. Results showed that the present model can give good estimations for simulating convective heat transfer cooling during battery operation. The developed thermal model is useful in structuring the flow system and determining the appropriate cooling capacity for a specified design prerequisite of the battery system.

High elastic modulus polymer electrolytes suitable for preventing thermal runaway in lithium batteries  

DOE Patents [OSTI]

A polymer that combines high ionic conductivity with the structural properties required for Li electrode stability is useful as a solid phase electrolyte for high energy density, high cycle life batteries that do not suffer from failures due to side reactions and dendrite growth on the Li electrodes, and other potential applications. The polymer electrolyte includes a linear block copolymer having a conductive linear polymer block with a molecular weight of at least 5000 Daltons, a structural linear polymer block with an elastic modulus in excess of 1.times.10.sup.7 Pa and an ionic conductivity of at least 1.times.10.sup.-5 Scm.sup.-1. The electrolyte is made under dry conditions to achieve the noted characteristics. In another aspect, the electrolyte exhibits a conductivity drop when the temperature of electrolyte increases over a threshold temperature, thereby providing a shutoff mechanism for preventing thermal runaway in lithium battery cells.

Thermally stable hyperbranched polyether-based polymer electrolyte for lithium-ion batteries  

Science Journals Connector (OSTI)

A thermally stable polymer matrix, comprising hyperbranched polyether PHEMO (poly(3-{2-[2-(2-hydroxyethoxy) ethoxy] ethoxy}methyl-3'-methyloxetane)) and PVDF-HFP (poly(vinylidene fluoride-hexafluoropropylene)), has been successfully prepared for applications in lithium-ion batteries. This type of polymer electrolyte has been made by adding different amounts of lithium bis(oxalate)borate (LiBOB) to the polymer matrix. Its thermal and structural properties were measured using differential scanning calorimetry and x-ray diffraction. Experimental results show that the polymer electrolyte system possesses good thermal stability, with a decomposition temperature above 420?°C. The ionic conductivity of the polymer electrolyte system is dependent on the lithium salt content, reaching a maximum of 1.1 ? 10?5?S?cm?1 at 30?°C and 2.3 ? 10?4?S?cm?1 at 80?°C when doped with 10?wt% LiBOB.

Thermal investigation of lithium-ion battery module with different cell arrangement structures and forced air-cooling strategies  

Science Journals Connector (OSTI)

Abstract Thermal management needs to be carefully considered in the lithium-ion battery module design to guarantee the temperature of batteries in operation within a narrow optimal range. This article firstly explores the thermal performance of battery module under different cell arrangement structures, which includes: 1 × 24, 3 × 8 and 5 × 5 arrays rectangular arrangement, 19 cells hexagonal arrangement and 28 cells circular arrangement. In addition, air-cooling strategies are also investigated by installing the fans in the different locations of the battery module to improve the temperature uniformity. Factors that influence the cooling capability of forced air cooling are discussed based on the simulations. The three-dimensional computational fluid dynamics (CFD) method and lumped model of single cell have been applied in the simulation. The temperature distributions of batteries are quantitatively described based on different module patterns, fan locations as well as inter-cell distance, and the conclusions are arrived as follows: when the fan locates on top of the module, the best cooling performance is achieved; the most desired structure with forced air cooling is cubic arrangement concerning the cooling effect and cost, while hexagonal structure is optimal when focus on the space utilization of battery module. Besides, the optimized inter-cell distance in battery module structure has been recommended.

Combined experimental and numerical study of thermal management of battery module consisting of multiple Li-ion cells  

Science Journals Connector (OSTI)

Abstract Lithium ion (Li-ion) batteries are promising power sources for hybrid powertrain systems, and the thermal management of batteries has been identified as a critical issue both for safety and efficiency concerns. This work studied thermal management of a Li-ion battery module both experimentally and computationally. A battery module consisting of multiple cells was fabricated and experimentally tested in a wind tunnel facility. Systematic tests were performed under various flow velocities, charging and discharging current, and module configuration. Computationally, a high-fidelity two dimensional computational fluid dynamics (CFD) model was developed to capture the detailed dynamics of thermal management of the cells. Temperature rise of cells and pressure measurements were recorded in the experiments, and compared with CFD model simulations. Reasonable agreement was obtained, confirming the validity of the model. The validated model was then applied to study the power consumption required by the thermal management system. The results obtained in this combined experimental and numerical study are expected to be valuable for the optimized design of battery modules and the development of reduced-order models.

Thermal Stability Enhancement of Polyethylene Separators by Gamma-ray Irradiation for Lithium Ion Batteries  

Science Journals Connector (OSTI)

The thermal stability of polyethylene (PE) separators irradiated by 50, 100, and 150 kGy dose gamma-rays is investigated when they are exposed to high-temperature environments. The gamma-ray irradiated separators have much lower Gurley numbers and higher ionic conductivity than a non-irradiated separator after storage at 100 and 120 °C. These results indicate that the thermal stability of PE separators can be drastically improved by gamma-ray irradiation. Even after storage at 120 °C for 1 h, the gamma-ray irradiated separator is maintaining its own structure. A cell assembled with a gamma-ray irradiated separator exhibits better rate-capability and cyclic performance than a pristine PE separator. The positive effects of gamma-ray irradiation are examined in detail with the purpose of improving battery performance.

Determination of Thermal Contact Conductance of Metal Tabs for Battery Ultrasonic Welding Process  

SciTech Connect (OSTI)

A new experimental apparatus and data analysis algorithm were used to determine the thermal contact conductance between 0.2-mm-thick pure aluminum battery tabs as a function of contact pressure from 3.6 to 14.4 MPa. Specimens were sandwiched between one optically transparent and one infrared (IR) transparent glass windows, and heated up from one side by an intense short pulse of flash light. The temperature transient on the other side was measured by an IR camera. In order to determine the thermal contact conductance, two experiment configurations having different number of Al specimen layers were used. Numerical heat conduction simulations showed that the thermal contact conductance strongly depended on the ratio of the maximum temperature rise between the two configurations. Moreover, this ratio was not sensitive to the uncertainties of other thermal properties. Through the simulation results, a simple correlation between the gap conductance and the ratio was established. Therefore, once the ratio of the temperature rise between two configurations was experimentally measured, the thermal contact conductance could be readily determined from the correlation. The new method was fast and robust. Most importantly, the data analysis algorithm improved the measurement accuracy by considerably reducing the uncertainties associated with the thermophysical properties of materials and measurement system.

An experimental study of heat pipe thermal management system with wet cooling method for lithium ion batteries  

Science Journals Connector (OSTI)

Abstract An effective battery thermal management (BTM) system is required for lithium-ion batteries to ensure a desirable operating temperature range with minimal temperature gradient, and thus to guarantee their high efficiency, long lifetime and great safety. In this paper, a heat pipe and wet cooling combined BTM system is developed to handle the thermal surge of lithium-ion batteries during high rate operations. The proposed BTM system relies on ultra-thin heat pipes which can efficiently transfer the heat from the battery sides to the cooling ends where the water evaporation process can rapidly dissipate the heat. Two sized battery packs, 3 Ah and 8 Ah, with different lengths of cooling ends are used and tested through a series high-intensity discharges in this study to examine the cooling effects of the combined BTM system, and its performance is compared with other four types of heat pipe involved BTM systems and natural convection cooling method. A combination of natural convection, fan cooling and wet cooling methods is also introduced to the heat pipe BTM system, which is able to control the temperature of battery pack in an appropriate temperature range with the minimum cost of energy and water spray.

A rapid estimation and sensitivity analysis of parameters describing the behavior of commercial Li-ion batteries including thermal analysis  

Science Journals Connector (OSTI)

Abstract In this work, a methodology based on rigorous model fitting and sensitivity analysis is presented to determine the parameters describing the physicochemical behavior of commercial pouch Li-ion batteries of high-capacity (16 A h), utilized in electric vehicles. It is intended for a rapid estimation of the kinetic and transport parameters, state of charge and health of a Li-ion battery when chemical information is not available, or for a brand new system. A pseudo 2-D model comprised of different contributions reported in the literature is utilized to describe the mass, charge and thermal balances of the cell and porous electrodes; and adapted to the battery chemistry under study. The sensitivity analysis of key model parameters is conducted to determine confidence intervals, using Analysis of Variance (ANOVA) for non-linear models. Also individual multi-parametric sensitivity analysis is conducted to assess the impact of the model parameters on battery voltage. The battery is comprised of multiple cells in parallel containing carbon anodes and LiNi1/3Co1/3Mn1/3O2 (NMC) cathodes with maximum and cut-off voltages of 4.2 and 2.7 V, respectively. Mass and charge transfer limitations during the discharge/charge of the battery are discussed as a function of State of Charge (SOC). A thermal analysis is also conducted to estimate the temperature rise on the surface of the battery. This modeling methodology can be extended to the analysis of other chemistry types of Li-ion batteries, as well as the evaluation of other material phenomena including capacity fade.

Experiment and simulation of a LiFePO4 battery pack with a passive thermal management system using composite phase change material and graphite sheets  

Science Journals Connector (OSTI)

Abstract A passive thermal management system (TMS) for LiFePO4 battery modules using phase change material (PCM) as the heat dissipation source to control battery temperature rise is developed. Expanded graphite matrix and graphite sheets are applied to compensate low thermal conductivity of PCM and improve temperature uniformity of the batteries. Constant current discharge and mixed charge-discharge duties were applied on battery modules with and without PCM on a battery thermal characteristics test platform. Experimental results show that PCM cooling significantly reduces the battery temperature rise during short-time intense use. It is also found that temperature uniformity across the module deteriorates with the increasing of both discharge time and current rates. The maximum temperature differences at the end of 1C and 2C-rate discharges are both less than 5°C, indicating a good performance in battery thermal uniformity of the passive TMS. Experiments on warm-keeping performance show that the passive TMS can effectively keep the battery within its optimum operating temperature for a long time during cold weather uses. A three dimensional numerical model of the battery pack with the passive TMS was conducted using ANSYS Fluent. Temperature profiles with respect to discharging time reveal that simulation shows good agreement with experiment at 1C-discharge rate.

Operation strategy for a lab-scale grid-connected photovoltaic generation system integrated with battery energy storage  

Science Journals Connector (OSTI)

Abstract The operation strategy for a lab-scale grid-connected photovoltaic generation system integrated with battery energy storage is proposed in this paper. The photovoltaic generation system is composed of a full-bridge inverter, a DC–DC boost converter, an isolated bidirectional DC–DC converter, a solar cell array and a battery set. Since the battery set acts as an energy buffer to adjust the power generation of the solar cell array, the negative impact on power quality caused by the intermittent and unstable output power from a solar cell array is alleviated, so the penetration rate of the grid-connected photovoltaic generation system is increased. A lab-scale prototype is developed to verify the performance of the system. The experimental results show that it achieves the expected performance.

Modeling of passive thermal management for electric vehicle battery packs with PCM between cells  

Science Journals Connector (OSTI)

Abstract A passive thermal management system is examined for an electric vehicle battery pack. Phase change material (PCM) is infused in foam layers separating the lithium-ion (Li-ion) cells. Known operating conditions lead to selecting a suitable PCM for the application, n-octadecane wax. Suitable porous foam for infusion is decided on through experimentation. Finite volume based simulations are conducted to study the thermal behavior of a 4 cell sub-module. The effect of different discharge rates are compared for this sub-module, with and without the PCM's presence. The results show that the maximum temperature in the system is decreased up to 7.3 K by replacing dry foam with PCM-soaked “wet foam”. The addition of PCM also makes the temperature distribution more uniform across the cells. The modeling results give indication of the quantity of PCM required, show the influence of the transient melt behavior under dynamic operating conditions, and examine design constraints associated with this approach.

A review of nuclear batteries  

Science Journals Connector (OSTI)

Abstract This paper reviews recent efforts in the literature to miniaturize nuclear battery systems. The potential of a nuclear battery for longer shelf-life and higher energy density when compared with other modes of energy storage make them an attractive alternative to investigate. The performance of nuclear batteries is a function of the radioisotope(s), radiation transport properties and energy conversion transducers. The energy conversion mechanisms vary significantly between different nuclear battery types, where the radioisotope thermoelectric generator, or RTG, is typically considered a performance standard for all nuclear battery types. The energy conversion efficiency of non-thermal-type nuclear batteries requires that the two governing scale lengths of the system, the range of ionizing radiation and the size of the transducer, be well-matched. Natural mismatches between these two properties have been the limiting factor in the energy conversion efficiency of small-scale nuclear batteries. Power density is also a critical performance factor and is determined by the interface of the radioisotope to the transducer. Solid radioisotopes are typically coated on the transducer, forcing the cell power density to scale with the surface area (limiting power density). Methods which embed isotopes within the transducer allow the power density to scale with cell volume (maximizing power density). Other issues that are examined include the limitations of shelf-life due to radiation damage in the transducers and the supply of radioisotopes to sustain a commercial enterprise. This review of recent theoretical and experimental literature indicates that the physics of nuclear batteries do not currently support the objectives of miniaturization, high efficiency and high power density. Instead, the physics imply that nuclear batteries will be of moderate size and limited power density. The supply of radioisotopes is limited and cannot support large scale commercialization. Niche applications for nuclear batteries exist, and advances in materials science may enable the development of high-efficiency solid-state nuclear batteries in the near term.

Fluorinated Phosphazene Co-solvents for Improved Thermal and Safety Performance in Lithium-Ion Battery Electrolytes  

SciTech Connect (OSTI)

The safety of lithium-ion batteries is coming under increased scrutiny as they are being adopted for large format applications especially in the vehicle transportation industry and for grid-scale energy storage. The primary short-comings of lithium-ion batteries are the flammability of the liquid electrolyte and sensitivity to high voltage and elevated temperatures. We have synthesized a series of non-flammable fluorinated phosphazene liquids and blended them with conventional carbonate solvents. While the use of these phosphazenes as standalone electrolytes is highly desirable, they simply do not satisfy all of the many requirements that must be met such as high LiPF6 solubility and low viscosity, thus we have used them as additives and co-solvents in blends with typical carbonates. The physical and electrochemical properties of the electrolyte blends were characterized, and then the blends were used to build 2032-type coin cells which were evaluated at constant current cycling rates from C/10 to C/1. We have evaluated the performance of the electrolytes by determining the conductivity, viscosity, flash point, vapor pressure, thermal stability, electrochemical window, cell cycling data, and the ability to form solid electrolyte interphase (SEI) films. This paper presents our results on a series of chemically similar fluorinated cyclic phosphazene trimers, the FM series, which has exhibited numerous beneficial effects on battery performance, lifetimes, and safety aspects.

Conventional Rankine Cycle uses water as the working fluid whereas ORC uses organic compound as the working fluid and it is particularly suitable for low temperature applications. The ORC and the solar collector will be sized according to the solar flux distribution in the Republic of Yemen for the required power output of 50 kW. This will be a micro power generation system that consists of two cycles the solar thermal cycle that harness solar energy and the power cycle which is the ORC that generates electricity. As for the solar thermal cycle heat transfer fluid (HTF) circulates the cycle while absorbing thermal energy from the sun through a parabolic trough collector and then storing it in a thermal storage to increase system efficiency and maintains system operation during low radiation. The heat is then transferred to the organic fluid in the ORC via a heat exchanger. The organic fluids to be used and analyzed in the ORC are hydrocarbons R600a and R290.

Thermal management optimization of an air-cooled Li-ion battery module using pin-fin heat sinks for hybrid electric vehicles  

Science Journals Connector (OSTI)

Abstract Three dimensional transient thermal analysis of an air-cooled module that contains prismatic Li-ion cells next to a special kind of aluminum pin fin heat sink whose heights of pin fins increase linearly through the width of the channel in air flow direction was studied for thermal management of Lithium-ion battery pack. The effects of pin fins arrangements, discharge rates, inlet air flow velocities, and inlet air temperatures on the battery were investigated. The results showed that despite of heat sinks with uniform pin fin heights that increase the standard deviation of the temperature field, using this kind of pin fin heat sink compare to the heat sink without pin fins not only decreases the bulk temperature inside the battery, but also decreases the standard deviation of the temperature field inside the battery as well. Increasing the inlet air temperature leads to decreasing the standard deviation of the temperature field while increases the maximum temperature of the battery. Furthermore, increasing the inlet air velocity first increases the standard deviation of the temperature field till reaches to the maximum point, and after that decreases. Also, increasing the inlet air velocity leads to decrease in the maximum temperature of the battery.

3D Thermal and Electrochemical Model for Spirally Wound Large Format Lithium-ion Batteries (Presentation)  

SciTech Connect (OSTI)

In many commercial cells, long tabs at both cell sides, leading to uniform potentials along the spiral direction of wound jelly rolls, are rarely seen because of their high manufacturing cost. More often, several metal strips are welded at discrete locations along both current collector foils. With this design, the difference of electrical potentials is easily built up along current collectors in the spiral direction. Hence, the design features of the tabs, such as number, location and size, can be crucial factors for spiral-shaped battery cells. This paper presents a Li-ion battery cell model having a 3-dimensional spiral mesh involving a wound jellyroll structure. Further results and analysis will be given regarding impacts of tab location, number, and size.

Analytical thermal model validation for Cassini radioisotope thermoelectric generator  

SciTech Connect (OSTI)

The Saturn-bound Cassini spacecraft is designed to rely, without precedent, on the waste heat from its three radioisotope thermoelectric generators (RTGs) to warm the propulsion module subsystem, and the RTG end dome temperature is a key determining factor of the amount of waste heat delivered. A previously validated SINDA thermal model of the RTG was the sole guide to understanding its complex thermal behavior, but displayed large discrepancies against some initial thermal development test data. A careful revalidation effort led to significant modifications and adjustments of the model, which result in a doubling of the radiative heat transfer from the heat source support assemblies to the end domes and bring up the end dome and flange temperature predictions to within 2 C of the pertinent test data. The increased inboard end dome temperature has a considerable impact on thermal control of the spacecraft central body. The validation process offers an example of physically-driven analytical model calibration with test data from not only an electrical simulator but also a nuclear-fueled flight unit, and has established the end dome temperatures of a flight RTG where no in-flight or ground-test data existed before.

Stochastic scenario-based model and investigating size of battery energy storage and thermal energy storage for micro-grid  

Science Journals Connector (OSTI)

Abstract Energy storage systems (ESS) are designed to accumulate energy when production exceeds demand and to make it available at the user’s request. They can help match energy supply and demand, exploit the variable production of renewable energy sources (e.g. solar and wind), increase the overall efficiency of the energy system and reduce CO2 emissions. This paper presents a unit commitment formulation for micro-grid that includes a significant number of grid parallel PEM-Fuel Cell Power Plants (PEM-FCPPs) with ramping rate and minimum up and down time constraints. The aim of this problem is to determine the optimum size of energy storage devices like hydrogen, thermal energy and battery energy storages in order to schedule the committed units’ output power while satisfying practical constraints and electrical/thermal load demand over one day with 15 min time step. In order to best use of multiple PEM-FCPPs, hydrogen storage management is carried out. Also, since the electrical and heat load demand are not synchronized, it could be useful to store the extra heat of PEM-FCPPs in the peak electrical load in order to satisfy delayed heat demands. Due to uncertainty nature of electrical/thermal load, photovoltaic and wind turbine output power and market price, a two-stage scenario-based stochastic programming model, where the first stage prescribes the here-and-now variables and the second stage determines the optima value of wait-and-see variables under cost minimization. Quantitative results show the usefulness and viability of the suggested approach.

Sustainable solar thermal power generation (STPG) technologies in Indian context  

SciTech Connect (OSTI)

India is a fast developing country. Some of the factors like population growth, industrialization, liberalization in economic policies, green revolution and awareness toward the environment, are increasing the electricity demand rapidly. As per the 14th Power Survey Report, an energy deficit of (+) 9% and peak demand deficit of (+) 18% have been estimated. Keeping in view the liberalization in economic policies, this deficit may be higher by the year 2000 AD. An estimation indicates that India is blessed with solar energy to the tune of 5 x 10{sup 15} kWh/yr. Being clean and inexhaustible source of energy, it can be used for large-scale power generation in the country. Keeping in view the present state-of-art technologies for STPG in MW range, best possible efforts are required to be made by all the concerned, to develop sustainable STPG technology of the future, specially for tropical regions. Standardization of vital equipment is an important aspect. There are a few required criteria like simple and robust technology, its transfer and adaptation in tropical climate conditions; high plant load factor without fossil-fired backup; availability of plant during evening peak and night hours; least use of fragile components, and capacity optimization for MW plants as per solar irradiance and environmental factors. In this paper, efforts have been made to compare the different STPG technologies. On the basis, of literature surveyed and studies carried out by the author, it may be stated that Central Receiver System technologies using molten salt and volumetric air receiver, along with molten salt and ceramic thermal storage respectively seems to be suitable and comparable in Indian context. Performance of SOLAR-TWO and PHOEBUS plants may be decisive.

Thermal aging of electrolytes used in lithium-ion batteries – An investigation of the impact of protic impurities and different housing materials  

Science Journals Connector (OSTI)

Abstract Thermal degradation products in lithium-ion batteries result mainly from hydrolysis sensitivity of lithium hexafluorophosphate (LiPF6). As organic carbonate solvents contain traces of protic impurities, the thermal decomposition of electrolytes is enhanced. Therefore, resulting degradation products are studied with nuclear magnetic resonance spectroscopy (NMR) and gas chromatography mass spectrometry (GC–MS). The electrolyte contains 1 M LiPF6 in a binary mixture of ethylene carbonate (EC) and diethylene carbonate (DEC) in a ratio of 1:2 (v/v) and is aged at ambient and elevated temperature. The impact of protic impurities, either added as deionized water or incorporated in positive electrode material, upon aging is investigated. Further, the influence of different housing materials on the electrolyte degradation is shown. Difluorophosphoric acid is identified as main decomposition product by NMR-spectroscopy. Traces of other decomposition products are determined by headspace GC–MS. Acid–base and coulometric titration are used to determine the total amount of acid and water content upon aging, respectively. The aim of this investigation is to achieve profound understanding about the thermal decomposition of one most common used electrolyte in a battery-like housing material.

A thermal-electrochemical model that gives spatial-dependent growth of solid electrolyte interphase in a Li-ion battery  

Science Journals Connector (OSTI)

Abstract The formation of a SEI layer and its growth cause internal resistance increase and capacity loss, leading to performance degradation of lithium-ion batteries. In order to comprehensively investigate the effects of SEI growth on battery performance, a one-dimensional thermal-electrochemical model was developed. This model is equipped with a growth mechanism of the SEI layer coupled with thermal evolution, based on the diffusional process of the solvent through the SEI layer and the kinetic process at the interface between the solid and liquid phases. The model is able to reveal the effects of diffusivity, reaction kinetics and temperature on SEI layer growth and cell capacity fade. We show that depending on the SEI thickness, the growth can be kinetics-limited or diffusion-limited. With the layer becoming thicker, its growth rate slows down gradually due to increased diffusion resistance. The SEI layer grows faster during charge than discharge due to the difference in the electron flux through the SEI layer and the temperature change during cycling. Temperature rise due to reaction and joule heating accelerates the SEI layer growth, leading to more capacity loss. Our model can provide insights on position-dependent SEI growth rate and be used to guide the strategic monitoring location.

Metal Hydride Thermal Storage: Reversible Metal Hydride Thermal Storage for High-Temperature Power Generation Systems  

SciTech Connect (OSTI)

HEATS Project: PNNL is developing a thermal energy storage system based on a Reversible Metal Hydride Thermochemical (RMHT) system, which uses metal hydride as a heat storage material. Heat storage materials are critical to the energy storage process. In solar thermal storage systems, heat can be stored in these materials during the day and released at night—when the sun is not out—to drive a turbine and produce electricity. In nuclear storage systems, heat can be stored in these materials at night and released to produce electricity during daytime peak-demand hours. PNNL’s metal hydride material can reversibly store heat as hydrogen cycles in and out of the material. In a RHMT system, metal hydrides remain stable in high temperatures (600- 800°C). A high-temperature tank in PNNL’s storage system releases heat as hydrogen is absorbed, and a low-temperature tank stores the heat until it is needed. The low-cost material and simplicity of PNNL’s thermal energy storage system is expected to keep costs down. The system has the potential to significantly increase energy density.

Thermal Analysis of Step 2 GPHS for Next Generation Radioisotope Power Source Missions  

Science Journals Connector (OSTI)

The Step 2 General Purpose Heat Source (GPHS) is a slightly larger and more robust version of the heritage GPHS modules flown on previous Radioisotope Thermoelectric Generator (RTG) missions like Galileo Ulysses and Cassini. The Step 2 GPHS is to be used in future small radioisotope power sources such as the Stirling Radioisotope Generator (SRG110) and the Multi?Mission Radioisotope Thermoelectric Generator (MMRTG). New features include an additional central web of Fine Weave Pierced Fabric (FWPF) graphite in the aeroshell between the two Graphite Impact Shells (GIS) to improve accidental reentry and impact survivability and an additional 0.1?inch of thickness to the aeroshell broad faces to improve ablation protection. This paper details the creation of the thermal model using Thermal Desktop and AutoCAD interfaces and provides comparisons of the model to results of previous thermal analysis models of the heritage GPHS. The results of the analysis show an anticipated decrease in total thermal gradient from the aeroshell to the iridium clads compared to the heritage results. In addition the Step 2 thermal model is investigated under typical SRG110 boundary conditions with cover gas and gravity environments included where applicable to provide preliminary guidance for design of the generator. Results show that the temperatures of the components inside the GPHS remain within accepted design limits during all envisioned mission phases.

Predictive Models of Li-ion Battery Lifetime (Presentation)  

SciTech Connect (OSTI)

Predictive models of Li-ion battery reliability must consider a multiplicity of electrochemical, thermal and mechanical degradation modes experienced by batteries in application environments. Complicating matters, Li-ion batteries can experience several path dependent degradation trajectories dependent on storage and cycling history of the application environment. Rates of degradation are controlled by factors such as temperature history, electrochemical operating window, and charge/discharge rate. Lacking accurate models and tests, lifetime uncertainty must be absorbed by overdesign and warranty costs. Degradation models are needed that predict lifetime more accurately and with less test data. Models should also provide engineering feedback for next generation battery designs. This presentation reviews both multi-dimensional physical models and simpler, lumped surrogate models of battery electrochemical and mechanical degradation. Models are compared with cell- and pack-level aging data from commercial Li-ion chemistries. The analysis elucidates the relative importance of electrochemical and mechanical stress-induced degradation mechanisms in real-world operating environments. Opportunities for extending the lifetime of commercial battery systems are explored.

Development of New Generation of Thermally-Enhanced Fiber Glass Insulation  

SciTech Connect (OSTI)

This report presents experimental and numerical results from thermal performance studies. The purpose of this Cooperative Research and Development Agreement (CRADA) between UT-Battelle, LLC and John s Manville was to design a basic concept of a new generation of thermally-enhanced fiber glass insulation. Different types of Phase Change Materials (PCMs) have been tested as dynamic components in buildings during the last 4 decades. Most historical studies have found that PCMs enhance building energy performance. Some PCM-enhanced building materials, like PCM-gypsum boards or PCM-impregnated concretes have already found their limited applications in different countries. Today, continued improvements in building envelope technologies suggest that throughout Southern and Central U.S. climates, residences may soon be routinely constructed with PCM in order to maximize insulation effectiveness and maintain low heating and cooling loads. The proposed thermally-enhanced fiber glass insulation will maximize this integration by utilizing a highly-efficient building envelope with high-R thermal insulation, active thermal mass and superior air-tightness. Improved thermal resistance will come from modifications in infrared internal characteristics of the fiber glass insulation. Thermal mass effect can be provided by proprietary thermally-active microencapsulated phase change material (PCM). Work carried out at the Oak Ridge National Laboratory (ORNL) on the CRADA is described in this report.

4th Generation District Heating (4GDH): Integrating smart thermal grids into future sustainable energy systems  

Science Journals Connector (OSTI)

Abstract This paper defines the concept of 4th Generation District Heating (4GDH) including the relations to District Cooling and the concepts of smart energy and smart thermal grids. The motive is to identify the future challenges of reaching a future renewable non-fossil heat supply as part of the implementation of overall sustainable energy systems. The basic assumption is that district heating and cooling has an important role to play in future sustainable energy systems – including 100 percent renewable energy systems – but the present generation of district heating and cooling technologies will have to be developed further into a new generation in order to play such a role. Unlike the first three generations, the development of 4GDH involves meeting the challenge of more energy efficient buildings as well as being an integrated part of the operation of smart energy systems, i.e. integrated smart electricity, gas and thermal grids.

A search for thermal isomerization of olefins to carbenes: Thermal generations of the silicon-nitrogen double bond  

SciTech Connect (OSTI)

The first part of this thesis will search for the thermal isomerization of olefins to carbenes which is predicted to be a high energy process by calculations and has only been observed in a few strained olefins. The possibility of thermal isomerization of simple olefins to carbenes will be explored. Substitution of a silyl group on the double bond of an olefin allows a potential intermediate which has a {beta}-radical to the silyl group during the cis-trans isomerization. The effects of a trimethylsilyl group on this isomerization are the subject of this study. The second part of this thesis will include the generation and chemistry of intermediates containing a silicon-nitrogen double bond. The isomerization of parent silanimine to the aminosilylene was calculated to be a high energy process. New approaches to the silicon-nitrogen double bond will also be presented. 92 refs., 12 figs., 11 tabs.

Generation of pulse-modulated induction thermal plasma at atmospheric pressure  

Science Journals Connector (OSTI)

The radio frequency induction thermal plasma of sufficiently high electric power for materials processing has been successfully generated with a pulsemodulated operating condition. A solid-stateamplifier which supplies the electric power with a nominal frequency of 1 MHz was employed for the pulsing plasma generation. The Ar–H 2 plasma was generated at a high power level of 17 kW at atmospheric pressure. Typically the plasma remained stable until the pulse duty factor went down to 30% when the period of the high power level was 5 ms and the low power level was about 6 kW.

The modelling of biochemical-thermal coupling effect on gas generation and transport in MSW landfill  

Science Journals Connector (OSTI)

The landfill gas generation was investigated based on the theories of the thermodynamics, microbial dynamics and chemical dynamics. The coupling model was developed for describing the gas transport and heat release. And the relationship between the gas generation rate and the temperature was proposed. The parameters in the gas generation model were obtained by bioreactor test in order to evaluate the volume of gas production of the Erfeishan landfill in China. The simulation results shown that the operating life of the landfill will be overestimated if the model does not consider the thermal effect during degradation of the solid substrate.

Lithium batteries for pulse power  

SciTech Connect (OSTI)

New designs of lithium batteries having bipolar construction and thin cell components possess the very low impedance that is necessary to deliver high-intensity current pulses. The R D and understanding of the fundamental properties of these pulse batteries have reached an advanced level. Ranges of 50--300 kW/kg specific power and 80--130 Wh/kg specific energy have been demonstrated with experimental high-temperature lithium alloy/transition-metal disulfide rechargeable bipolar batteries in repeated 1- to 100-ms long pulses. Other versions are designed for repetitive power bursts that may last up to 20 or 30 s and yet may attain high specific power (1--10 kW/kg). Primary high-temperature Li-alloy/FeS{sub 2} pulse batteries (thermal batteries) are already commercially available. Other high-temperature lithium systems may use chlorine or metal-oxide positive electrodes. Also under development are low-temperature pulse batteries: a 50-kW Li/SOCl{sub 2} primary batter and an all solid-state, polymer-electrolyte secondary battery. Such pulse batteries could find use in commercial and military applications in the near future. 21 refs., 8 figs.

Impact of wind power on generation economy and emission from coal based thermal power plant  

Science Journals Connector (OSTI)

The major chunk of power generation is based on coal fueled thermal power plant. Due to increasing demand of power there will be future crises of coal reservoirs and its costing. Apart from this, coal based thermal power plant is the main source of environmental emissions like carbon dioxides (CO2), sulfur dioxides (SO2) and oxides of nitrogen (NOx) which not only degrades the air quality but also is responsible for global warming, acid rain etc. This paper proposes a combined working of Doubly Fed Induction Generator (DFIG) with coal based Synchronous Generator (SG) in the MATLAB environment. STATCOM is suggested at common coupling point to maintain voltage stability and also maintain the system in synchronism. Analysis have been made for environmental emissions, coal requirement and system economy for both the cases, when the total load supplied by only SG and with the combination. Emission analysis have been also made with the application of washed coal in SG. With the impact of DFIG energy generation from SG have been reduces which proportionally affects on coal requirement, generation cost and environmental emissions. Application of washed coal improves the performance of SG and also reduces the environmental emissions.

Apparatus for nuclear transmutation and power production using an intense accelerator-generated thermal neutron flux  

DOE Patents [OSTI]

Apparatus for nuclear transmutation and power production using an intense accelerator-generated thermal neutron flux. High thermal neutron fluxes generated from the action of a high power proton accelerator on a spallation target allows the efficient burn-up of higher actinide nuclear waste by a two-step process. Additionally, rapid burn-up of fission product waste for nuclides having small thermal neutron cross sections, and the practicality of small material inventories while achieving significant throughput derive from employment of such high fluxes. Several nuclear technology problems are addressed including 1. nuclear energy production without a waste stream requiring storage on a geological timescale, 2. the burn-up of defense and commercial nuclear waste, and 3. the production of defense nuclear material. The apparatus includes an accelerator, a target for neutron production surrounded by a blanket region for transmutation, a turbine for electric power production, and a chemical processing facility. In all applications, the accelerator power may be generated internally from fission and the waste produced thereby is transmuted internally so that waste management might not be required beyond the human lifespan.

Study on generating of thermal neutron scattering cross sections for LiH  

SciTech Connect (OSTI)

LiH is designated as a promising moderator and shielding material because of its low density, high melting point and large fraction of H atoms. However, lack of the thermal neutron cross sections of LiH makes numerical calculation deviate from experimental data to some extent. As a result, it is necessary to study LiH thermal kernel effect. The phonon property of LiH has been investigated by first-principles calculations using the plane-wave pseudo potential method with CASTEP code. The scattering law and the thermal neutron scattering cross sections for Li and H have been generated using this distribution. The results have been compared with zirconium hydride data. The GASKET and NJOY/LEAPR codes have been used in the calculation of scattering law, whose results have been compared with the reference; the discrepancy mainly comes from phonon spectrums and its expansion. LEAPR had the capability to compute scattering through larger energy and momentum transfers than GASKET did. By studying LiH phonon spectrum and constructing the model of LiH thermal kernel and scattering matrix, the ACE format LiH thermal neutron cross sections for MCNP software could be made and used for reactor Neutronics calculation.

Models for Battery Reliability and Lifetime  

SciTech Connect (OSTI)

Models describing battery degradation physics are needed to more accurately understand how battery usage and next-generation battery designs can be optimized for performance and lifetime. Such lifetime models may also reduce the cost of battery aging experiments and shorten the time required to validate battery lifetime. Models for chemical degradation and mechanical stress are reviewed. Experimental analysis of aging data from a commercial iron-phosphate lithium-ion (Li-ion) cell elucidates the relative importance of several mechanical stress-induced degradation mechanisms.

Power plants coordination for economic and environmental load dispatch of thermal power plants with wind generation systems  

Science Journals Connector (OSTI)

Economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain generation scheduling of thermal power plants at optimum fuel cost and emissions. Due to limited availability of quality coal, issue of environmental emissions and high prices of coal, installation of renewable energy systems are suggested in power grid. Renewable energy system preferably wind generators are used in co-working with thermal plant which reduces generation cost, coal requirement and environmental emissions. This paper presents Newton-Raphson method to obtain ELD and EED. System simulation and programming is carried out in MATLAB® environment. Analysis has been made on generation cost and for nitrous oxides emissions only due to its harmful effects and its rising tendency with excess air. Price penalty factor is also calculated to determine emission cost. Doubly fed induction generator (DFIG) is suggested as wind energy systems in combination with coal-based thermal plant. Performance results related to generation scheduling, transmission line loading, bus voltages, total cost and environmental emissions are shown for coal-based thermal power plant and with co-generation. The investigation shows that with co-generation, coal-based thermal power plant runs at minimum emissions level which further reflects on the generation economy.

An improved absorption generator for solar-thermal powered heat pumps. Part 1: Feasibility  

SciTech Connect (OSTI)

Solar heated absorption chiller installations have been, typically, very expensive for their rating. The need to keep the liquid flowing within the collectors as cool as possible to enhance collector thermal efficiency, conflicts with the need to operate the absorption chiller at a higher temperature. The compromise usually results in poor collector efficiency as well as a relatively poor specific chiller effect. The proposed vortex generator permits a heat pump to operate efficiently with relatively low temperature solar heated fluid (70--80 C). As a result, the collectors are cooler and much more efficient. In addition, the specific heat pumping capacity is about 27% greater than conventional systems operating at the same reduced generator temperatures and, therefore, a smaller chiller is required. The economic consequences of these benefits will be presented in Part 2.

The compromise usually results in poor collector efficiency as well as a relatively poor specific chiller effect. The proposed vortex generator permits a heat pump to operate efficiently with relatively low temperature solar heated fluid (70--80 C). As a result, the collectors are cooler and more efficient. As noted in Part 1, the specific heat pumping capacity is about 27% greater than conventional systems operating at the same reduced generator temperatures. Therefore, a smaller, less expensive chiller is required. The reduced investment in solar arrays and absorption chillers is estimated along with a range of paybacks.

Security constrained generation scheduling for grids incorporating wind, photovoltaic and thermal power  

Science Journals Connector (OSTI)

Abstract In this paper, security constrained generation scheduling (SCGS) problem for a grid incorporating thermal, wind and photovoltaic (PV) units is formulated. The formulation takes into account the stochastic nature of both wind and PV power output and imbalance charges due to mismatch between the actual and scheduled wind and PV power outputs. A hybrid technique in which the basic elements are a genetic algorithm (GA) with artificial neural network (ANN) and a priority list (PL) is used to minimize the total operating costs while satisfying all operational constraints considering both conventional and renewable energy generators. Numerical results are reported and discussed based on the simulation performed on the IEEE 24-bus reliability test system. The results demonstrate the efficiency of the proposed approach to reduce the total production cost for real time operation. Moreover, the results verified that the proposed approach can be applied to different problem dimensions and can score more favorably compared with analytical techniques.

Batteries: Overview of Battery Cathodes  

SciTech Connect (OSTI)

The very high theoretical capacity of lithium (3829 mAh/g) provided a compelling rationale from the 1970's onward for development of rechargeable batteries employing the elemental metal as an anode. The realization that some transition metal compounds undergo reductive lithium intercalation reactions reversibly allowed use of these materials as cathodes in these devices, most notably, TiS{sub 2}. Another intercalation compound, LiCoO{sub 2}, was described shortly thereafter but, because it was produced in the discharged state, was not considered to be of interest by battery companies at the time. Due to difficulties with the rechargeability of lithium and related safety concerns, however, alternative anodes were sought. The graphite intercalation compound (GIC) LiC{sub 6} was considered an attractive candidate but the high reactivity with commonly used electrolytic solutions containing organic solvents was recognized as a significant impediment to its use. The development of electrolytes that allowed the formation of a solid electrolyte interface (SEI) on surfaces of the carbon particles was a breakthrough that enabled commercialization of Li-ion batteries. In 1990, Sony announced the first commercial batteries based on a dual Li ion intercalation system. These devices are assembled in the discharged state, so that it is convenient to employ a prelithiated cathode such as LiCoO{sub 2} with the commonly used graphite anode. After charging, the batteries are ready to power devices. The practical realization of high energy density Li-ion batteries revolutionized the portable electronics industry, as evidenced by the widespread market penetration of mobile phones, laptop computers, digital music players, and other lightweight devices since the early 1990s. In 2009, worldwide sales of Li-ion batteries for these applications alone were US$ 7 billion. Furthermore, their performance characteristics (Figure 1) make them attractive for traction applications such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs); a market predicted to be potentially ten times greater than that of consumer electronics. In fact, only Liion batteries can meet the requirements for PHEVs as set by the U.S. Advanced Battery Consortium (USABC), although they still fall slightly short of EV goals. In the case of Li-ion batteries, the trade-off between power and energy shown in Figure 1 is a function both of device design and the electrode materials that are used. Thus, a high power battery (e.g., one intended for an HEV) will not necessarily contain the same electrode materials as one designed for high energy (i.e., for an EV). As is shown in Figure 1, power translates into acceleration, and energy into range, or miles traveled, for vehicular uses. Furthermore, performance, cost, and abuse-tolerance requirements for traction batteries differ considerably from those for consumer electronics batteries. Vehicular applications are particularly sensitive to cost; currently, Li-ion batteries are priced at about $1000/kWh, whereas the USABC goal is $150/kWh. The three most expensive components of a Li-ion battery, no matter what the configuration, are the cathode, the separator, and the electrolyte. Reduction of cost has been one of the primary driving forces for the investigation of new cathode materials to replace expensive LiCoO{sub 2}, particularly for vehicular applications. Another extremely important factor is safety under abuse conditions such as overcharge. This is particularly relevant for the large battery packs intended for vehicular uses, which are designed with multiple cells wired in series arrays. Premature failure of one cell in a string may cause others to go into overcharge during passage of current. These considerations have led to the development of several different types of cathode materials, as will be covered in the next section. Because there is not yet one ideal material that can meet requirements for all applications, research into cathodes for Li-ion batteries is, as of this writ

Exergoeconomic analysis of high concentration photovoltaic thermal co-generation system for space cooling  

Science Journals Connector (OSTI)

Abstract This paper provides an exergetic analysis of a 10 MW high concentration photovoltaic thermal (HCPVT) power plant case study located in Hammam Bou Hadjar, Algeria. The novel HCPVT multi-energy carrier plant converts 25% of the direct normal irradiance (DNI) into electrical energy and 62.5% to low grade heat for a combined efficiency of 87.5%. The HCPVT system employs a point focus dish concentrator with a cooled PV receiver module. The novel “hot-water” cooling approach is used for energy reuse purposes and is enabled by our state-of-the-art substrate integrated micro-cooling technology. The high performance cooler of the receiver with a thermal resistance of <0.12 cm2 K/W enables the receiver module to handle concentrations of up to 5000 suns. In the present study, a concentration of 2000 suns allows using coolant fluid temperatures of up to 80 °C. This key innovation ensures reliable operation of the triple junction PV (3JPV) cells used and also allows heat recovery for utilization in other thermal applications such as space cooling, heating, and desalination. Within this context, an exergoeconomics analysis of photovoltaic thermal co-generation for space cooling is presented in this manuscript. The valuation method presented here for the HCPVT multi-energy carrier plant comprises both the technical and economic perspectives. The proposed model determines how the cost structure is evolving in four different scenarios by quantifying the potential thermal energy demand in Hammam Bou Hadjar. The model pins down the influence of technical details such as the exergetic efficiency to the economic value of the otherwise wasted heat. The thermal energy reuse boosts the power station?s overall yield, reduces total average costs and optimizes power supply as fixed capital is deployed more efficiently. It is observed that even though potential cooling demand can be substantial (19,490 MWh per household), prices for cooling should be 3 times lower than those of electricity in Algeria (18 USD/MWh) to be competitive. This implies a need to reach economies of scale in the production of individual key components of the HCPVT system. The net present value (NPV) is calculated taking growth rates and the system?s modular efficiencies into account, discounted over 25 years. Scenario 1 shows that even though Algeria currently has no market for thermal energy, a break-even quantity (49,728 MWh) can be deduced by taking into account the relation between fixed costs and the marginal profit. Scenario 2 focuses on the national growth rate needed to break even, i.e. +10.92%. Scenario 3 illustrates thermal price variations given an increase in the Coefficient of Performance (COP) of a thermally driven adsorption chiller after year 10. In this case, the price for cooling will decrease from 18 USD/MWh to 14 USD/MWh. Finally, scenario 4 depicts Hammam Bou Hadjar?s potential cooling demand per household and the growth rate needed to break even if a market for heat would exist.

Advanced Battery Manufacturing (VA)  

SciTech Connect (OSTI)

LiFeBATT has concentrated its recent testing and evaluation on the safety of its batteries. There appears to be a good margin of safety with respect to overheating of the cells and the cases being utilized for the batteries are specifically designed to dissipate any heat built up during charging. This aspect of LiFeBATT’s products will be even more fully investigated, and assuming ongoing positive results, it will become a major component of marketing efforts for the batteries. LiFeBATT has continued to receive prismatic 20 Amp hour cells from Taiwan. Further testing continues to indicate significant advantages over the previously available 15 Ah cells. Battery packs are being assembled with battery management systems in the Danville facility. Comprehensive tests are underway at Sandia National Laboratory to provide further documentation of the advantages of these 20 Ah cells. The company is pursuing its work with Hybrid Vehicles of Danville to critically evaluate the 20 Ah cells in a hybrid, armored vehicle being developed for military and security applications. Results have been even more encouraging than they were initially. LiFeBATT is expanding its work with several OEM customers to build a worldwide distribution network. These customers include a major automotive consulting group in the U.K., an Australian maker of luxury off-road campers, and a number of makers of E-bikes and scooters. LiFeBATT continues to explore the possibility of working with nations that are woefully short of infrastructure. Negotiations are underway with Siemens to jointly develop a system for using photovoltaic generation and battery storage to supply electricity to communities that are not currently served adequately. The IDA has continued to monitor the progress of LiFeBATT’s work to ensure that all funds are being expended wisely and that matching funds will be generated as promised. The company has also remained current on all obligations for repayment of an IDA loan and lease payments for space to the IDA. A commercial venture is being formed to utilize the LiFeBATT product for consumer use in enabling photovoltaic powered boat lifts. Field tests of the system have proven to be very effective and commercially promising. This venture is expected to result in significant sales within the next six months.

Time dependent evolution of RF-generated non-thermal particle distributions in fusion plasmas  

Science Journals Connector (OSTI)

We describe fully self-consistent time-dependent simulations of radio frequency (RF) generated ion distributions in the ion cyclotron range of frequencies and RF-generated electron distributions in the lower hybrid range of frequencies using combined Fokker–Planck and full wave electromagnetic field solvers. In each regime, the non-thermal particle distributions have been used in synthetic diagnostic codes to compare with diagnostic measurements from experiment, thus providing validation of the simulation capability. The computational intensive simulations require multiple full wave code runs that iterate with a Fokker–Planck code. We will discuss advanced algorithms that have been implemented to accelerate both the massively parallel full wave simulations as well as the iteration with the distribution code. A vector extrapolation method (Sidi A 2008 Comput. Math. Appl. 56) that permits Jacobian-free acceleration of the traditional fixed point iteration technique is used to reduce the number of iterations needed between the distribution and wave codes to converge to self-consistency. The computational burden of the parallel full wave codes has been reduced by using a more efficient two level parallel decomposition that improves the strong scaling of the codes and reduces the communication overhead.

Many military platforms that currently use the BA-5590 primary battery or the BB-390A/U rechargeable battery are limited in performance by low storage capacity and long recharge times. Thermo Power Corporation with team members JX Crystals and Essential Research Inc. is developing an advanced thermophotovoltaic (TPV) battery substitute that will provide higher storage capacity lower weight and instantaneous recharging (by refueling). The TPV battery substitute incorporates several advanced design features including: an evacuated and sealed enclosure for the emitter and PV cells to minimize unwanted convection heat transfer from the emitter to PV cells; selective tungsten emitter with a well matched gallium antimonide PV cell receiver; optical filter to recycle nonconvertible radiant energy; and a silicon carbide thermal recuperator to recover thermal energy from exhaust gases.

Safety Hazards of Batteries Safety Hazards of Batteries Battery technology is at the heart of much of our technological revolution. One of the most prevalent rechargeable batteries in use today is the Lithium-ion battery. Cell phones, laptop computers, GPS systems, iPods, and even cars are now using lithium- ion rechargeable battery technology. In fact, you probably have a lithium-ion battery in your pocket or purse right now! Although lithium-ion batteries are very common there are some inherent dangers when using ANY battery. Lithium cells are like any other technology - if they are abused and not used for their intended purpose catastrophic results may occur, such as: first-, second-, and third-degree burns, respiratory problems, fires, explosions, and even death. Please handle the lithium-ion batteries with care and respect.

NREL/CCSE PEV Battery Second Use Project (Presentation)  

SciTech Connect (OSTI)

This presentation describes the Battery Second Use Project. Preliminary analysis results show (1) the impact of competing technologies, (2) potential revenue generation, and (3) supply and demand of the second use of plug-in electric vehicle batteries. The impact of competing technologies are: maximum salve value of a used battery will be limited by future battery prices, under favorable conditions, second use can only discount today's battery prices by 12% or less, however, second use will offer batteries to second applications at reduced cost (typically < $170/kWh). Revenue streams are highly variable, allowable battery costs are highly sensitive to balance-of-system costs, and batteries need to be very cheap for these applications to be viable. Supply and demand show that high-value applications have both competition and small markets, and supply from plug-in electric vehicles has the potential to overwhelm many second use markets.

I n s i t u thermal oxidation for surface cleaning and mask generation prior to selective area epitaxy  

Science Journals Connector (OSTI)

Dry thermal oxidation of GaAs and AlAs has been carried out in an organometallic chemical vapor deposition system. This i n s i t u process performed either before or after an epitaxialgrowth serves the purposes of surface cleaning and mask generation for selective area epitaxy of various III?V semiconductors.AlAsoxidized immediately after growth and patterned for the next regrowth provides better oxide?semiconductor interfaces and minimizes wafer handling. Pre?epitaxy oxidation at 435?°C on a patterned wafer with AlAs/GaAs areas resulted in a selective oxide mask. Since thermal oxides of GaAssublime at temperatures >600?°C a 700?°C pregrowth annealing thus thermally cleans the oxidizedGaAs areas while the oxides of AlAs remain as a mask for the following regrowth. Photoluminescence results indicate that high quality regrown interfaces have been obtained.

Membranes and separators for flowing electrolyte batteries-a review  

SciTech Connect (OSTI)

Flowing electrolyte batteries are rechargeable electrochemical storage devices in which externally stored electrolytes are circulated through the cell stack during charge or discharge. The potential advantages that flow batteries offer compared to other secondary batteries include: 1) ease of thermal and electrolyte management, 2) simple electrochemistry, 3) deep cycling capability, and 4) minimal loss of capacity with cycling. However, flow batteries are more complex than other secondary batteries and consequently may cost more and may be less reliable. Flow batteries are being developed for utility load leveling, electric vehicles, solar photovoltaic and wind turbine application. The status of flow batteries has recently been reviewed by Clark et al. The flowing electrolyte batteries place rigorous demands on the performance of separators and membranes. The operating characteristics of the iron/chromium redox battery were changed in order to accommodate the limitations in membrane performance. Low cost alternatives to the presently used membrane must be found before the zinc/ferricyanide battery can be economically feasible. The zinc/bromine battery's efficiency could be improved if a suitably selective membrane were available. It is anticipated that better and less costly membranes to meet these needs will be developed as more is learned about their preparation and performance.

Battery Lifetime Analysis and Simulation Tool (BLAST) Documentation  

SciTech Connect (OSTI)

The deployment and use of lithium-ion batteries in automotive and stationary energy storage applications must be optimized to justify their high up-front costs. Given that batteries degrade with use and storage, such optimizations must evaluate many years of operation. As the degradation mechanisms are sensitive to temperature, state-of-charge histories, current levels, and cycle depth and frequency, it is important to model both the battery and the application to a high level of detail to ensure battery response is accurately predicted. To address these issues, the National Renewable Energy Laboratory has developed the Battery Lifetime Analysis and Simulation Tool (BLAST) suite of tools. This suite of tools pairs NREL's high-fidelity battery degradation model with a battery electrical and thermal performance model, application-specific electrical and thermal performance models of the larger system (e.g., an electric vehicle), application-specific system use data (e.g., vehicle travel patterns and driving data), and historic climate data from cities across the United States. This provides highly realistic, long-term predictions of battery response and thereby enables quantitative comparisons of varied battery use strategies.

Novel green illumination energy for LED with ocean battery materials  

Science Journals Connector (OSTI)

This paper launches novel materials of LED with ocean battery. Ocean battery employs sea water existing by the nature as energy materials to drive LED lamp lighting. The analysing methods are thermal-, electric- and illumination-performance experiments to discuss the novel green illumination techniques. Ocean battery and LED are all DC components, there is no energy loss of current converter between them, and the ocean battery has more electricity in LED illumination. Vapour chamber (VC) and aluminium (AL) materials are assigned to be the LED PCBs. Results show that the effective thermal conductivity of the VCPCB is many times higher than that of the ALPCB, proving that it can effectively reduce the temperature of the LED and obtain more uniform luminance. And the output voltage and LED lighting start unstable resulting from the air bubble of ocean battery slight vibration.

Lithium Metal Anodes for Rechargeable Batteries  

SciTech Connect (OSTI)

Rechargeable lithium metal batteries have much higher energy density than those of lithium ion batteries using graphite anode. Unfortunately, uncontrollable dendritic lithium growth inherent in these batteries (upon repeated charge/discharge cycling) and limited Coulombic efficiency during lithium deposition/striping has prevented their practical application over the past 40 years. With the emerging of post Li-ion batteries, safe and efficient operation of lithium metal anode has become an enabling technology which may determine the fate of several promising candidates for the next generation of energy storage systems, including rechargeable Li-air battery, Li-S battery, and Li metal battery which utilize lithium intercalation compounds as cathode. In this work, various factors which affect the morphology and Coulombic efficiency of lithium anode will be analyzed. Technologies used to characterize the morphology of lithium deposition and the results obtained by modeling of lithium dendrite growth will also be reviewed. At last, recent development in this filed and urgent need in this field will also be discussed.

Flow Battery System Design for Manufacturability.  

SciTech Connect (OSTI)

Flow battery energy storage systems can support renewable energy generation and increase energy efficiency. But, presently, the costs of flow battery energy storage systems can be a significant barrier for large-scale market penetration. For cost- effective systems to be produced, it is critical to optimize the selection of materials and components simultaneously with the adherence to requirements and manufacturing processes to allow these batteries and their manufacturers to succeed in the market by reducing costs to consumers. This report analyzes performance, safety, and testing requirements derived from applicable regulations as well as commercial and military standards that would apply to a flow battery energy storage system. System components of a zinc-bromine flow battery energy storage system, including the batteries, inverters, and control and monitoring system, are discussed relative to manufacturing. The issues addressed include costs and component availability and lead times. A service and support model including setup, maintenance and transportation is outlined, along with a description of the safety-related features of the example flow battery energy storage system to promote regulatory and environmental, safety, and health compliance in anticipation of scale manufacturing.

Latent Heat Based High Temperature Solar Thermal Energy Storage for Power Generation  

Science Journals Connector (OSTI)

Abstract The design of a phase change material based high temperature solar thermal energy storage device is presented. Said unit will be used as an energy reserve for a 1 kWe domestic CCHP system using a Stirling engine to produce electric power. The thermal energy storage is conducted by means of the exploitation of the latent heat of fusion of the material contained inside the tank. This method was chosen because a great energy density is obtained and, at the same time, it is possible to extract the stored energy with very small variations on the temperature, which is a favorable feature for its intended purpose. The selection of the phase change material is discussed and the design of the different components of the proposed storage model is described. It is analyzed, as well, the insulating solution applied that minimizes heat losses. Finally, a comparison between experimental results of the tests performed on the first built to scale prototype and the data obtained from computer simulations is shown.

The Salty Science of the Aluminum-Air Battery  

Science Journals Connector (OSTI)

Fruit batteries and saltwater batteries are excellent ways to explore simple circuits in the classroom. These are examples of air batteries1 in which metal reacts with oxygen in the air in order to generate free electrons which flow through an external circuit and do work. Students are typically told that the salt or fruit water acts as an electrolyte to bring electrons from the anode to the cathode. That's true but it leaves the battery as a black box. Physics teachers often don't have the background to explain the chemistry behind these batteries. We've written this paper to explore the electrochemistry behind an air battery using coppercathode aluminum anode and saltwater.

Recent advances in lithium–sulfur batteries  

Science Journals Connector (OSTI)

Abstract Lithium–sulfur (Li–S) batteries have attracted much attention lately because they have very high theoretical specific energy (2500 Wh kg?1), five times higher than that of the commercial LiCoO2/graphite batteries. As a result, they are strong contenders for next-generation energy storage in the areas of portable electronics, electric vehicles, and storage systems for renewable energy such as wind power and solar energy. However, poor cycling life and low capacity retention are main factors limiting their commercialization. To date, a large number of electrode and electrolyte materials to address these challenges have been investigated. In this review, we present the latest fundamental studies and technological development of various nanostructured cathode materials for Li–S batteries, including their preparation approaches, structure, morphology and battery performance. Furthermore, the development of other significant components of Li–S batteries including anodes, electrolytes, additives, binders and separators are also highlighted. Not only does the intention of our review article comprise the summary of recent advances in Li–S cells, but also we cover some of our proposals for engineering of Li–S cell configurations. These systematic discussion and proposed directions can enlighten ideas and offer avenues in the rational design of durable and high performance Li–S batteries in the near future.

Batteries Batteries battery/cell diagram Battery/Cell Diagram Batteries are important to our everyday lives and show up in various consumer electronics and appliances, from MP3 players to laptops to our vehicles. Batteries play an important role in our vehicles and are gradually becoming more and more important as they assume energy storage responsibilities from fuel in vehicle propulsion systems. A battery is a device that stores chemical energy in its active materials and converts it, on demand, into electrical energy by means of an electrochemical reaction. An electrochemical reaction is a chemical reaction involving the transfer of electrons, and it is that reaction which creates electricity. There are three main parts of a battery: the anode, cathode, and electrolyte. The anode is the "fuel" electrode which gives up electrons to the external circuit to create the flow of electrons or electricity. The cathode is the oxidizing electrode which accepts electrons in the external circuit. Finally, the electrolyte carries the electric current, as ions, inside the cell, between the anode and cathode.

Temperature and thermal stress distributions for the HFIR permanent reflector generated by nuclear heating  

SciTech Connect (OSTI)

The beryllium permanent reflector of the High Flux Isotope Reactor has the main functions for slowing down and reflecting the neutrons and housing the experimental facilities. The reflector is heated as a result of the nuclear reaction. Heat is removed mainly by the cooling water passing through the densely distributed coolant holes along the vertical or axial direction of the reflector. The reflector neutronic distribution and its heating rate are calculated by J.C. Gehin of the Oak Ridge National Laboratory by applying the Monte Carlo Code MCNP. The heat transfer boundary conditions along several reflector interfaces are estimated to remove additional heat from the reflector. The present paper is to report the calculation results of the temperature and the thermal stress distributions of the permanent reflector by applying the computer aided design code I-DEAS and the finite element code ABAQUS. The present calculation is to estimate the high stress areas as a result of the new beam tube cutouts along the horizontal mid-plane of the reflector of the recent reactor upgrade project. These high stresses were not able to be calculated in the preliminary design analysis in earlier 60`s. The heat transfer boundary conditions are used in this redesigned calculation. The material constants and the acceptance criteria for the allowable stresses are mainly based on that assumed in the preliminary design report.

Assessing the Power Generation Solution by Thermal-chemical Conversion of Meat Processing Industry Waste  

Science Journals Connector (OSTI)

Abstract The paper presents a waste to energy conversion solution using a pyro-air-gasification process applied to biodegradable residues from meat processing industry integrated with small scale thermodynamic cycle for power generation. The solution of air- gasification at atmospheric pressure is based on experimental research and engineering computation developed during the study. The input data, such as: waste chemical composition, low/high heating value and proximate analysis, correspond to real waste products, sampled directly from the industrial processing line. Separate drying as first stage pre-treatment and integrated partial drying inside the reactor was used. The syngas low heating value of about 4.3 MJ/Nm3 is insured by its combustible fraction (H2– 12.2%, CO – 19.2%, CH4 – 1.6%). According to syngas composition the thermodynamic cycle was chosen – Otto gas engine. For a given waste feed-in flow considered in our computation of about 110 kg/h the power output obtained is about 50 kWel. The global energy efficiency of the unit is about 15%. The results offer answers to energy recovery waste disposal for residues with characteristics that are not suitable for classic incineration or limit the energy efficiency of the process making it non-economical (the average humidity of the raw waste is about 42% in mass). The research focused on waste to energy conversion process energy efficiency, waste neutralization and power generation.

This report is the first of four volumes that identify and assess the environmental, health, and safety issues involved in using sodium-sulfur (Na/S) battery technology as the energy source in electric and hybrid vehicles that may affect the commercialization of Na/S batteries. This and the other reports on recycling, shipping, and vehicle safety are intended to help the Electric and Hybrid Propulsion Division of the Office of Transportation Technologies in the US Department of Energy (DOE/EHP) determine the direction of its research, development, and demonstration (RD&D) program for Na/S battery technology. The reports review the status of Na/S battery RD&D and identify potential hazards and risks that may require additional research or that may affect the design and use of Na/S batteries. This volume covers cell design and engineering as the basis of safety for Na/S batteries and describes and assesses the potential chemical, electrical, and thermal hazards and risks of Na/S cells and batteries as well as the RD&D performed, under way, or to address these hazards and risks. The report is based on a review of the literature and on discussions with experts at DOE, national laboratories and agencies, universities, and private industry. Subsequent volumes will address environmental, health, and safety issues involved in shipping cells and batteries, using batteries to propel electric vehicles, and recycling and disposing of spent batteries. The remainder of this volume is divided into two major sections on safety at the cell and battery levels. The section on Na/S cells describes major component and potential failure modes, design, life testing and failure testing, thermal cycling, and the safety status of Na/S cells. The section on batteries describes battery design, testing, and safety status. Additional EH&S information on Na/S batteries is provided in the appendices.

Costs of lithium-ion batteries for vehicles  

SciTech Connect (OSTI)

One of the most promising battery types under development for use in both pure electric and hybrid electric vehicles is the lithium-ion battery. These batteries are well on their way to meeting the challenging technical goals that have been set for vehicle batteries. However, they are still far from achieving the current cost goals. The Center for Transportation Research at Argonne National Laboratory undertook a project for the US Department of Energy to estimate the costs of lithium-ion batteries and to project how these costs might change over time, with the aid of research and development. Cost reductions could be expected as the result of material substitution, economies of scale in production, design improvements, and/or development of new material supplies. The most significant contributions to costs are found to be associated with battery materials. For the pure electric vehicle, the battery cost exceeds the cost goal of the US Advanced Battery Consortium by about $3,500, which is certainly enough to significantly affect the marketability of the vehicle. For the hybrid, however, the total cost of the battery is much smaller, exceeding the cost goal of the Partnership for a New Generation of Vehicles by only about $800, perhaps not enough to deter a potential buyer from purchasing the power-assist hybrid.

Temperature-Dependent Battery Models for High-Power Lithium-Ion Batteries  

SciTech Connect (OSTI)

In this study, two battery models for a high-power lithium ion (Li-Ion) cell were compared for their use in hybrid electric vehicle simulations in support of the U.S. Department of Energy's Hybrid Electric Vehicle Program. Saft America developed the high-power Li-Ion cells as part of the U.S. Advanced Battery Consortium/U.S. Partnership for a New Generation of Vehicles programs. Based on test data, the National Renewable Energy Laboratory (NREL) developed a resistive equivalent circuit battery model for comparison with a 2-capacitance battery model from Saft. The Advanced Vehicle Simulator (ADVISOR) was used to compare the predictions of the two models over two different power cycles. The two models were also compared to and validated with experimental data for a US06 driving cycle. The experimental voltages on the US06 power cycle fell between the NREL resistive model and Saft capacitance model predictions. Generally, the predictions of the two models were reasonably close to th e experimental results; the capacitance model showed slightly better performance. Both battery models of high-power Li-Ion cells could be used in ADVISOR with confidence as accurate battery behavior is maintained during vehicle simulations.

Thin film battery/fuel cell power generation system. Topical report covering Task 5: the design, cost and benefit of an industrial cogeneration system, using a high-temperature solid-oxide-electrolyte (HTSOE) fuel-cell generator  

SciTech Connect (OSTI)

A literature search and review of the studies analyzing the relationship between thermal and electrical energy demand for various industries and applications resulted in several applications affording reasonable correlation to the thermal and electrical output of the HTSOE fuel cell. One of the best matches was in the aluminum industry, specifically, the Reynolds Aluminum Production Complex near Corpus Christi, Texas. Therefore, a preliminary design of three variations of a cogeneration system for this plant was effected. The designs were not optimized, nor were alternate methods of providing energy compared with the HTSOE cogeneration systems. The designs were developed to the extent necessary to determine technical practicality and economic viability, when compared with alternate conventional fuel (gas and electric) prices in the year 1990.

Phosphorus derivatives as electrolyte additives for lithium-ion battery: The removal of O2 generated from lithium-rich layered oxide cathode  

Science Journals Connector (OSTI)

Abstract Direct internal pressure measurements of the cylindrical Li-ion cells with a mixture of LiCoO2 and Li1.167Ni0.233Co0.1Mn0.467Mo0.033O2 (a solid solution between 0.4 Li2Mn0.8Ni0.1Mo0.1O3 and 0.6 LiNi0.4Co0.2Mn0.4O2) as cathode and graphite as anode have been performed during cell charging. Cell internal pressure at the end of charging is greatly reduced from 2.85 to 0.84–1.84 bar by adding a small amount of phosphorus derivatives such as triphenyl phosphine (TPP), ethyl diphenylphosphinite (EDP), and triethyl phosphite (TEP) into a carbonate-based electrolyte. The phosphorus derivatives are supposed to react with O2 generated from the decomposition of the Li2MnO3 component. The chemical states of additive molecules before and after the charging process have been characterized with a nuclear magnetic resonance (NMR) spectroscopy and gas chromatography–mass spectrometry (GC–MS). It has also been shown that those additives improve the cycle life when applied in coin full cells.

The Effect of Temperature on Capacity and Power in Cycled Lithium Ion Batteries  

SciTech Connect (OSTI)

The Idaho National Laboratory (INL) tested six Saft America HP-12 (Generation 2000), 12-Ah lithium ion cells to evaluate cycle life performance as a power assist vehicle battery. The cells were tested to investigate the effects of temperature on capacity and power fade. Test results showed that five of the six cells were able to meet the Power Assist Power and Energy Goals at the beginning of test and after 300,000 cycles using a Battery Size Factor of 44.3 cells. The initial Static Capacity tests showed that the capacities of the cells were stable for three discharges and had an average of 16.4 Ah. All the cells met the Self-Discharge goal, but failed to meet the Cold Cranking goal. As is typical for lithium ion cells, both power and capacity were diminished during the low-temperature Thermal Performance test and increased during the high-temperature Thermal Performance test. Capacity faded as expected over the course of 300,000 life cycles and showed a weak inverse relationship to increasing temperature. Power fade was mostly a result of cycling while temperature had a minor effect compared to cycle life testing. Consequently, temperature had very little effect on capacity and power fade for the proprietary G4 chemistry.

Analysis of Thermal Aging and Structural Stability of Li[Lix(Ni0.3Co0.1Mn0.6)1-x]O2 (x = 0.11) Cathode Active Material for Rechargeable Li-Ion Batteries  

Science Journals Connector (OSTI)

The high rate capability of Mn-rich Li[Lix(Ni0.3Co0.1Mn0.6)1-x]O2 (x = 0.11) cathode active materials is investigated by cycling the cell at a given rate for five cycles and keeping the cell idle under thermal control chamber for 10 h and the same process repeating up to 30 cycles. The before and after thermal aging of Mn-rich cathode materials deliver the initial discharge capacity of 153 and 157.32 mA h g-1 up to 30 cycles and also it is maintained the average specific discharge capacity of 140 mA h g-1 for before thermal aging and more than 90% capacity retention. After thermal aging of cathode materials have maintain the average specific discharge capacity of 155 mA h g-1 and more than 97% capacity retentions. During charging, they are not oxidized further; Ni2+ and at least part of Co3+ ions are oxidized to higher valence states. During the discharge reactions, the small amount of Mn3+ reduced to the Mn4+ and some part of Ni3+ ions are reduced to Ni4+. Also the Co3+ ions are fully reduced to the Co4+ state, which due to thermal aging studies does not have major affects in the Mn-rich layered structure under thermal control chamber. These thermal aging analyses are essential to achieve a deeper understanding of the structural defects and safety views for Li-ion batteries to use in electric vehicle technologies.

Thin-Film Battery with Lithium Anode Courtesy of Oak Ridge National Laboratory, Materials Science and Technology Division Thin-Film Lithium Batteries Resources with Additional Information The Department of Energy's 'Oak Ridge National Laboratory (ORNL) has developed high-performance thin-film lithium batteries for a variety of technological applications. These batteries have high energy densities, can be recharged thousands of times, and are only 10 microns thick. They can be made in essentially any size and shape. Recently, Teledyne licensed this technology from ORNL to make batteries for medical devices including electrocardiographs. In addition, new "textured" cathodes have been developed which have greatly increased the peak current capability of the batteries. This greatly expands the potential medical uses of the batteries, including transdermal applications for heart regulation.'

FY14 Milestone: Simulated Impacts of Life-Like Fast Charging on BEV Batteries (Management Publication)  

SciTech Connect (OSTI)

Fast charging is attractive to battery electric vehicle (BEV) drivers for its ability to enable long-distance travel and quickly recharge depleted batteries on short notice. However, such aggressive charging and the sustained vehicle operation that results could lead to excessive battery temperatures and degradation. Properly assessing the consequences of fast charging requires accounting for disparate cycling, heating, and aging of individual cells in large BEV packs when subjected to realistic travel patterns, usage of fast chargers, and climates over long durations (i.e., years). The U.S. Department of Energy's Vehicle Technologies Office has supported NREL's development of BLAST-V 'the Battery Lifetime Analysis and Simulation Tool for Vehicles' to create a tool capable of accounting for all of these factors. The authors present on the findings of applying this tool to realistic fast charge scenarios. The effects of different travel patterns, climates, battery sizes, battery thermal management systems, and other factors on battery performance and degradation are presented. The primary challenge for BEV batteries operated in the presence of fast charging is controlling maximum battery temperature, which can be achieved with active battery cooling systems.

Chapter 3 - Potential of Sodium-Sulfur Battery Energy Storage to Enable Further Integration of Wind  

Science Journals Connector (OSTI)

Abstract Wind generation is the leading alternative for environmentally responsible power generation and for energy independence in the future. However, wind power output cannot be controlled same as conventional generation, and wind is not necessarily available to serve peak load. In this chapter, the use of a Sodium Sulfur battery directly coupled with a wind farm to provide generation shifting for serving peak demand and for limiting the wind farm power output ramp-rate is discussed. Results from field operation of a 1 MW, 7.2 \\{MWh\\} Sodium Sulfur battery coupled with an 11.55 MW wind farm were provided to validate the battery’s ability to successfully carry out both the tasks. It is shown that the two tasks could be combined to achieve maximum benefit. Value addition from shifting wind generation to on-peak is calculated and the optimal ratio storage to wind ratio is discussed.

JV Task 46 - Development and Testing of a Thermally Integrated SOFC-Gasification System for Biomass Power Generation  

SciTech Connect (OSTI)

The Energy & Environmental Research Center has designed a biomass power system using a solid oxide fuel cell (SOFC) thermally integrated with a downdraft gasifier. In this system, the high-temperature effluent from the SOFC enables the operation of a substoichiometric air downdraft gasifier at an elevated temperature (1000 C). At this temperature, moisture in the biomass acts as an essential carbon-gasifying medium, reducing the equivalence ratio at which the gasifier can operate with complete carbon conversion. Calculations show gross conversion efficiencies up to 45% (higher heating value) for biomass moisture levels up to 40% (wt basis). Experimental work on a bench-scale gasifier demonstrated increased tar cracking within the gasifier and increased energy density of the resultant syngas. A series of experiments on wood chips demonstrated tar output in the range of 9.9 and 234 mg/m{sup 3}. Both button cells and a 100-watt stack was tested on syngas from the gasifier. Both achieved steady-state operation with a 22% and 15% drop in performance, respectively, relative to pure hydrogen. In addition, tar tolerance testing on button cells demonstrated an upper limit of tar tolerance of approximately 1%, well above the tar output of the gasifier. The predicted system efficiency was revised down to 33% gross and 27% net system efficiency because of the results of the gasifier and fuel cell experiments. These results demonstrate the feasibility and benefits of thermally integrating a gasifier and a high-temperature fuel cell in small distributed power systems.

THERMAL DESTRUCTION OF HIGHLY CHLORINATED MIXED WASTES WITHOUT GENERATING CORROSIVE OFF-GASES USING MOLTEN SALT OXIDATION (1,2)  

SciTech Connect (OSTI)

A pilot-scale MSO (Molten Salt Oxidation) system was used to process 45-gallons of a halogenated mixed waste that is difficult to treat with other thermal systems. The mixed waste was a halogenated solvent that consisted mostly of methylchloroform. The 80 weight percent of waste consisting of highly corrosive chlorine was captured in the first process vessel as sodium chloride. The sodium chloride leached chrome from that process vessel and the solidified salt exhibited the toxicity characteristic for chrome as measured by TCLP (Toxicity Characteristic Leaching Procedure) testing. The operating ranges for parameters such as salt bed temperature, off-gas temperature, and feed rate that enable sustained operation were identified. At feed rates below the sustainable limit, both processing capacity and maintenance requirements increased with feed rate. Design and operational modifications to increase the sustainable feed rate limit and reduce maintenance requirements reduced both salt carryover and volumetric gas flows.

Stability of polymer binders in Li-O2 batteries  

SciTech Connect (OSTI)

A number of polymers with various chemical structures were studied as binders for air electrodes in Li-O2 batteries. The nature of the polymer significantly affects the binding properties in the carbon electrodes thus altering the discharge performance of Li-O2 batteries. Stability of polymers to the aggressive reduced oxygen species generated during discharge was tested by ball milling them with KO2 and Li2O2, respectively. Most of the polymers decomposed under these conditions and mechanisms of the decompositions are proposed for some of the polymers. Polyethylene was found to have excellent stability and is suggested as robust binder for air electrodes in Li-O2 batteries.

Development of one-dimensional computer code DESOPT for thermal hydraulic design of sodium-heated once through steam generators  

Science Journals Connector (OSTI)

Once-through Steam Generator (SG) is a critical component of Liquid Metal Fast Breeder Reactor (LMFBR) plant. It is a counter current heat exchanger, in which heat is transferred from the hot sodium flowing on the shell side to water/steam in tube side. High pressure subcooled water enters the SG tube from bottom, gets heated up to saturation, goes through nucleate boiling, dry out and post dry out heat transfer, getting converted to saturated steam and finally gets superheated. For this the process design needs to be carried out accurately. A computer code DESOPT has been developed for the process design of straight vertical, serpentine and helical geometries and validated against reported designs in literature. Recently a test facility to test a 5.5 MWt sodium heated steam generator has been commissioned. The predictions of the code have been compared with the measurements and found satisfactory. This paper brings out different heat transfer mechanisms in SG and describes the one-dimensional code, its validation based on literature and in-house tests and presents the results of comparison between predicted and actual operation at different part loads.

Actively driven thermal radiation shield  

DOE Patents [OSTI]

A thermal radiation shield for cooled portable gamma-ray spectrometers. The thermal radiation shield is located intermediate the vacuum enclosure and detector enclosure, is actively driven, and is useful in reducing the heat load to mechanical cooler and additionally extends the lifetime of the mechanical cooler. The thermal shield is electrically-powered and is particularly useful for portable solid-state gamma-ray detectors or spectrometers that dramatically reduces the cooling power requirements. For example, the operating shield at 260K (40K below room temperature) will decrease the thermal radiation load to the detector by 50%, which makes possible portable battery operation for a mechanically cooled Ge spectrometer.

The Cosmic Battery in Astrophysical Accretion Disks  

E-Print Network [OSTI]

The aberrated radiation pressure at the inner edge of the accretion disk around an astrophysical black hole imparts a relative azimuthal velocity on the electrons with respect to the ions which gives rise to a ring electric current that generates large scale poloidal magnetic field loops. This is the Cosmic Battery established by Contopoulos and Kazanas in 1998. In the present work we perform realistic numerical simulations of this important astrophysical mechanism in advection-dominated accretion flows-ADAF. We confirm the original prediction that the inner parts of the loops are continuously advected toward the central black hole and contribute to the growth of the large scale magnetic field, whereas the outer parts of the loops are continuously diffusing outward through the turbulent accretion flow. This process of inward advection of the axial field and outward diffusion of the return field proceeds all the way to equipartition, thus generating astrophysically significant magnetic fields on astrophysicall...

Simulation of thermal stress influence on the Boom Clay kerogen (Oligocene, Belgium) in relation to long-term storage of high activity nuclear waste: I. Study of generated soluble compounds  

Science Journals Connector (OSTI)

Closed pyrolyses were performed on the Boom Clay kerogen to simulate the weak thermal stress applied during the in situ CERBERUS heating experiment (80 °C for 5 a). Two stronger thermal stresses, encompassing the range generally considered for the long-term disposal of high-activity nuclear waste (80 °C for 1 ka and 120 °C for 3 ka), were also simulated. Quantitative and qualitative studies were carried out on the products thus generated with a focus on the C12+ fraction, especially on its polar components. It thus appeared that the soluble C12+ fractions generated during these simulation experiments comprise a wide variety of polar O- and/or N-containing compounds, including carboxylic acids and phenols. The nature and/or the relative abundance of these polar compounds exhibit strong variations, with the extent of the thermal stress, reflecting the primary cracking of different types of structures with different thermal stability and the occurrence of secondary degradation reactions. These observations support the idea that the compounds, generated upon exposure of the Boom Clay kerogen to a low to moderate thermal stress, may affect the effectiveness of the geological barrier upon long-term storage of high-activity nuclear waste.

Assessment of generic solar thermal systems for large power applications: analysis of electric power generating costs for systems larger than 10 MWe  

SciTech Connect (OSTI)

Seven generic types of collectors, together with associated subsystems for electric power generation, were considered. The collectors can be classified into three categories: (1) two-axis tracking (with compound-curvature reflecting surfaces); (2) one-axis tracking (with single-curvature reflecting surfaces); and (3) nontracking (with low-concentration reflecting surfaces). All seven collectors were analyzed in conceptual system configurations with Rankine-cycle engines. In addition, two of the collectors were analyzed with Brayton-cycle engines, and one was analyzed with a Stirling-cycle engine. With these engine options, and the consideration of both thermal and electrical storage for the Brayton-cycle central receiver, 11 systems were formulated for analysis. Conceptual designs developed for the 11 systems were based on common assumptions of available technology in the 1990 to 2000 time frame. No attempt was made to perform a detailed optimization of each conceptual design. Rather, designs best suited for a comparative evaluation of the concepts were formulated. Costs were estimated on the basis of identical assumptions, ground rules, methodologies, and unit costs of materials and labor applied uniformly to all of the concepts. The computer code SOLSTEP was used to analyze the thermodynamic performance characteristics and energy costs of the 11 concepts. Year-long simulations were performed using meteorological and insolation data for Barstow, California. Results for each concept include levelized energy costs and capacity factors for various combinations of storage capacity and collector field size.

The Science of Battery Degradation.  

SciTech Connect (OSTI)

This report documents work that was performed under the Laboratory Directed Research and Development project, Science of Battery Degradation. The focus of this work was on the creation of new experimental and theoretical approaches to understand atomistic mechanisms of degradation in battery electrodes that result in loss of electrical energy storage capacity. Several unique approaches were developed during the course of the project, including the invention of a technique based on ultramicrotoming to cross-section commercial scale battery electrodes, the demonstration of scanning transmission x-ray microscopy (STXM) to probe lithium transport mechanisms within Li-ion battery electrodes, the creation of in-situ liquid cells to observe electrochemical reactions in real-time using both transmission electron microscopy (TEM) and STXM, the creation of an in-situ optical cell utilizing Raman spectroscopy and the application of the cell for analyzing redox flow batteries, the invention of an approach for performing ab initio simulation of electrochemical reactions under potential control and its application for the study of electrolyte degradation, and the development of an electrochemical entropy technique combined with x-ray based structural measurements for understanding origins of battery degradation. These approaches led to a number of scientific discoveries. Using STXM we learned that lithium iron phosphate battery cathodes display unexpected behavior during lithiation wherein lithium transport is controlled by nucleation of a lithiated phase, leading to high heterogeneity in lithium content at each particle and a surprising invariance of local current density with the overall electrode charging current. We discovered using in-situ transmission electron microscopy that there is a size limit to lithiation of silicon anode particles above which particle fracture controls electrode degradation. From electrochemical entropy measurements, we discovered that entropy changes little with degradation but the origin of degradation in cathodes is kinetic in nature, i.e. lower rate cycling recovers lost capacity. Finally, our modeling of electrode-electrolyte interfaces revealed that electrolyte degradation may occur by either a single or double electron transfer process depending on thickness of the solid-electrolyte- interphase layer, and this cross-over can be modeled and predicted.

As lithium metal reacts violently with water and can ignite into flame, modern lithium-ion batteries use carbon negative electrode and lithium metal oxide positive electrode. The electrolyte is usually based on a lithium salt in organic solution. Thin-film batteries use solid oxide or polymer electrolytes. Rechargeable lithium-ion batteries (containing an intercalation negative electrode) should not be confused with nonrechargeable lithium primary batteries (containing metallic lithium). This article outlines energy storage in lithium batteries, basic cell chemistry, positive electrode materials, negative electrode materials, electrolytes, and state-of-charge (SoC) monitoring.

3-Port Single-Stage PV & Battery Converter Improves Efficiency and Cost in Combined PV/Battery Systems  

SciTech Connect (OSTI)

Due to impressive cost reductions in recent years, photovoltaic (PV) generation is now able to produce electricity at highly competitive prices, but PV’s inherent intermittency reduces the potential value of this energy. The integration of battery storage with PV will be transformational by increasing the value of solar. Utility scale systems will benefit by firming intermittency including PV ramp smoothing, grid support and load shifting, allowing PV to compete directly with conventional generation. For distributed grid-tied PV adding storage will reduce peak demand utility charges, as well as providing backup power during power grid failures. The largest long term impact of combined PV and battery systems may be for delivering reliable off-grid power to the billions of individuals globally without access to conventional power grids, or for billions more that suffer from daily power outages. PV module costs no longer dominate installed PV system costs. Balance-of-System (BOS) costs including the PV inverter and installation now contribute the majority of installed system costs. Battery costs are also dropping faster than installation and battery power converter systems. In each of these separate systems power converters have become a bottleneck for efficiency, cost and reliability. These bottlenecks are compounded in hybrid power conversion systems that combine separate PV and battery converters. Hybrid power conversion systems have required multiple power converters hardware units and multiple power conversion steps adding to efficiency losses, product and installation costs, and reliability issues. Ideal Power Converters has developed and patented a completely new theory of operation for electronic power converters using its indirect EnergyPacket Switching™ topology. It has established successful power converter products for both PV and battery systems, and its 3-Port Hybrid Converter is the first product to exploit the topology’s capability for the industry’s first single-stage multi-port hybrid power converter. This unique low cost approach eliminates the hybrid power conversion bottlenecks when integrating batteries into PV systems. As result this product will significantly accelerate market adoption of these systems.

Lithium-Air Battery: High Performance Cathodes for Lithium-Air Batteries  

SciTech Connect (OSTI)

BEEST Project: Researchers at Missouri S&T are developing an affordable lithium-air (Li-Air) battery that could enable an EV to travel up to 350 miles on a single charge. Today’s EVs run on Li-Ion batteries, which are expensive and suffer from low energy density compared with gasoline. This new Li-Air battery could perform as well as gasoline and store 3 times more energy than current Li-Ion batteries. A Li-Air battery uses an air cathode to breathe oxygen into the battery from the surrounding air, like a human lung. The oxygen and lithium react in the battery to produce electricity. Current Li-Air batteries are limited by the rate at which they can draw oxygen from the air. The team is designing a battery using hierarchical electrode structures to enhance air breathing and effective catalysts to accelerate electricity production.

Multiphysics modeling of lithium ion battery capacity fading process with solid-electrolyte interphase growth by elementary reaction kinetics  

Science Journals Connector (OSTI)

Abstract A pseudo two-dimensional mathematical model is developed for a lithium ion battery, integrating the elementary reaction based solid-electrolyte interphase (SEI) growth model with multiple transport processes. The model is validated using the experimental data. Simulation results indicate that the operating temperature has great effect on the SEI layer generation and growth. Under different charging–discharging rates, it is found that high charging–discharging rate can intensify the battery capacity fading process. Different cooling conditions are then applied and show that enhanced surface convective cooling condition can effectively slow down the battery capacity fading. After that, the effect of electrolyte salt concentration and exchange current density are studied. It is found that raising the electrolyte salt concentration can improve the diffusion property of lithium ions, and stabilize the battery performance under lithium ion consumption induced resistance rising. It also suggests that improving exchange current density could greatly decrease the lithium ion battery capacity fading.

Understanding batteries on the micro- and nanometer scale  

ScienceCinema (OSTI)

In order to understand performance limitations and failure mechanisms of batteries, one has to investigate processes on the micro- and nanometer scale. A typical failure mechanism in lithium metal batteries is dendritic growth. During discharge, lithium is stripped of the anode surface and migrates to the cathode. During charge, lithium is deposited back on the anode. Repeated cycling can result in stripping and re-deposition that roughens the surface. The roughening of the surface changes the electric field and draws more metal to spikes that are beginning to grow. These can grow with tremendous mechanical force, puncture the separator, and directly connect the anode with the cathode which can create an internal short circuit. This can lead to an uncontrolled discharge reaction, which heats the cell and causes additional exothermic reactions leading to what is called thermal runaway. ORNL has developed a new technology called liquid electron microscopy. In a specially designed sample holder micro-chamber with electron-transparent windows, researchers can hold a liquid and take images of structures and particles at nanometer size. It's the first microscope holder of its kind used to investigate the inside of a battery while cycled.

Cascade redox flow battery systems  

DOE Patents [OSTI]

A reduction/oxidation ("redox") flow battery system includes a series of electrochemical cells arranged in a cascade, whereby liquid electrolyte reacts in a first electrochemical cell (or group of cells) before being directed into a second cell (or group of cells) where it reacts before being directed to subsequent cells. The cascade includes 2 to n stages, each stage having one or more electrochemical cells. During a charge reaction, electrolyte entering a first stage will have a lower state-of-charge than electrolyte entering the nth stage. In some embodiments, cell components and/or characteristics may be configured based on a state-of-charge of electrolytes expected at each cascade stage. Such engineered cascades provide redox flow battery systems with higher energy efficiency over a broader range of current density than prior art arrangements.

Ambient Operation of Li/Air Batteries  

SciTech Connect (OSTI)

In this work, Li/air batteries based on nonaqueous electrolytes were investigated in ambient conditions (with an oxygen partial pressure of 0.21 atm and relative humidity of ~20%). A heat-sealable polymer membrane was used as both an oxygen-diffusion membrane and as a moisture barrier for Li/air batteries. The membrane also can minimize the evaporation of the electrolyte from the batteries. Li/air batteries with this membrane can operate in ambient conditions for more than one month with a specific energy of 362 Wh kg-1, based on the total weight of the battery including its packaging. Among various carbon sources used in this work, Li/air batteries using Ketjenblack (KB) carbon-based air electrodes exhibited the highest specific energy. However, KB-based air electrodes expanded significantly and absorbed much more electrolyte than electrodes made from other carbon sources. The weight distribution of a typical Li/air battery using the KB-based air electrode was dominated by the electrolyte (~70%). Lithium-metal anodes and KB-carbon anodes account for only 5.12% and 5.78% of the battery weight, respectively. We also found that only ~ 20% of the mesopore volume of the air electrode was occupied by reaction products after discharge. To further improve the specific energy of the Li/air batteries, the microstructure of the carbon electrode needs to be further improved to absorb much less electrolyte while still holding significant amounts of reaction products
