Recent spectacular fires involving cell phones, laptops, and (here at LBNL) AA cells have made the news. These events are generally caused by overcharging and subsequent development of internal shorts. Before these batteries can be used in vehicle applications, improvement in cell safety is a must. We have been active in the area of lithium battery safety for many years. For example, a versatile, inexpensive overcharge protection approach developed in our laboratory, uses an electroactive polymer to act as a reversible, self-actuating, low resistance internal

The present invention provides for a lithium ion battery and process for creating such, comprising higher binder to carbon conductor ratios than presently used in the industry. The battery is characterized by much lower interfacial resistances at the anode and cathode as a result of initially mixing a carbon conductor with a binder, then with the active material. Further improvements in cycleability can also be realized by first mixing the carbon conductor with the active material first and then adding the binder.

Chemical Shuttle Additives in Lithium Ion Batteries  

SciTech Connect (OSTI)

The goals of this program were to discover and implement a redox shuttle that is compatible with large format lithium ion cells utilizing LiNi{sub 1/3}Mn{sub 1/3}Co{sub 1/3}O{sub 2} (NMC) cathode material and to understand the mechanism of redox shuttle action. Many redox shuttles, both commercially available and experimental, were tested and much fundamental information regarding the mechanism of redox shuttle action was discovered. In particular, studies surrounding the mechanism of the reduction of the oxidized redox shuttle at the carbon anode surface were particularly revealing. The initial redox shuttle candidate, namely 2-(pentafluorophenyl)-tetrafluoro-1,3,2-benzodioxaborole (BDB) supplied by Argonne National Laboratory (ANL, Lemont, Illinois), did not effectively protect cells containing NMC cathodes from overcharge. The ANL-RS2 redox shuttle molecule, namely 1,4-bis(2-methoxyethoxy)-2,5-di-tert-butyl-benzene, which is a derivative of the commercially successful redox shuttle 2,5-di-tert-butyl-1,4-dimethoxybenzene (DDB, 3M, St. Paul, Minnesota), is an effective redox shuttle for cells employing LiFePO{sub 4} (LFP) cathode material. The main advantage of ANL-RS2 over DDB is its larger solubility in electrolyte; however, ANL-RS2 is not as stable as DDB. This shuttle also may be effectively used to rebalance cells in strings that utilize LFP cathodes. The shuttle is compatible with both LTO and graphite anode materials although the cell with graphite degrades faster than the cell with LTO, possibly because of a reaction with the SEI layer. The degradation products of redox shuttle ANL-RS2 were positively identified. Commercially available redox shuttles Li{sub 2}B{sub 12}F{sub 12} (Air Products, Allentown, Pennsylvania and Showa Denko, Japan) and DDB were evaluated and were found to be stable and effective redox shuttles at low C-rates. The Li{sub 2}B{sub 12}F{sub 12} is suitable for lithium ion cells utilizing a high voltage cathode (potential that is higher than NMC) and the DDB is useful for lithium ion cells with LFP cathodes (potential that is lower than NMC). A 4.5 V class redox shuttle provided by Argonne National Laboratory was evaluated which provides a few cycles of overcharge protection for lithium ion cells containing NMC cathodes but it is not stable enough for consideration. Thus, a redox shuttle with an appropriate redox potential and sufficient chemical and electrochemical stability for commercial use in larger format lithium ion cells with NMC cathodes was not found. Molecular imprinting of the redox shuttle molecule during solid electrolyte interphase (SEI) layer formation likely contributes to the successful reduction of oxidized redox shuttle species at carbon anodes. This helps to understand how a carbon anode covered with an SEI layer, that is supposed to be electrically insulating, can reduce the oxidized form of a redox shuttle.

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.

Electronically conductive polymer binder for lithium-ion battery electrode  

DOE Patents [OSTI]

A family of carboxylic acid group containing fluorene/fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries. These binders enable the use of silicon as an electrode material as they significantly improve the cycle-ability of silicon by preventing electrode degradation over time. In particular, these polymers, which become conductive on first charge, bind to the silicon particles of the electrode, are flexible so as to better accommodate the expansion and contraction of the electrode during charge/discharge, and being conductive promote the flow battery current.

NANOWIRE CATHODE MATERIAL FOR LITHIUM-ION BATTERIES  

SciTech Connect (OSTI)

This project involved the synthesis of nanowire ã-MnO2 and characterization as cathode material for high-power lithium-ion batteries for EV and HEV applications. The nanowire synthesis involved the edge site decoration nanowire synthesis developed by Dr. Reginald Penner at UC Irvine (a key collaborator in this project). Figure 1 is an SEM image showing ã-MnO2 nanowires electrodeposited on highly oriented pyrolytic graphite (HOPG) electrodes. This technique is unique to other nanowire template synthesis techniques in that it produces long (>500 um) nanowires which could reduce or eliminate the need for conductive additives due to intertwining of fibers. Nanowire cathode for lithium-ion batteries with surface areas 100 times greater than conventional materials can enable higher power batteries for electric vehicles (EVs) and hybrid electric vehicles (HEVs). The synthesis of the ã-MnO2 nanowires was successfully achieved. However, it was not found possible to co-intercalate lithium directly in the nanowire synthesis. Based on input from proposal reviewers, the scope of the project was altered to attempt the conversion into spinel LiMn2O4 nanowire cathode material by solid state reaction of the ã-MnO2 nanowires with LiNO3 at elevated temperatures. Attempts to perform the conversion on the graphite template were unsuccessful due to degradation of the graphite apparently caused by oxidative attack by LiNO3. Emphasis then shifted to quantitative removal of the nanowires from the graphite, followed by the solid state reaction. Attempts to quantitatively remove the nanowires by several techniques were unsatisfactory due to co-removal of excess graphite or poor harvesting of nanowires. Intercalation of lithium into ã-MnO2 electrodeposited onto graphite was demonstrated, showing a partial demonstration of the ã-MnO2 material as a lithium-ion battery cathode material. Assuming the issues of nanowires removal can be solved, the technique does offer potential for creating high-power lithium-ion battery cathode needed for advanced EV and HEVs. Several technical advancements will still be required to meet this goal, and are likely topics for future SBIR feasibility studies.

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.

SciTech Connect (OSTI)

There need to be significant improvements made in lithium-ion battery technology, principally in the areas of safety and useful lifetimes to truly enable widespread adoption of large format batteries for the electrification of the light transportation fleet. In order to effect the transition to lithium ion technology in a timely fashion, one promising next step is through improvements to the electrolyte in the form of novel additives that simultaneously improve safety and useful lifetimes without impairing performance characteristics over wide temperature and cycle duty ranges. Recent efforts in our laboratory have been focused on the development of such additives with all the requisite properties enumerated above. We present the results of the study of novel phosphazene based electrolytes additives.

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.

Science Journals Connector (OSTI)

In view of the need to protect the global environment and save energy there has been strong demand for the development of lithium?ion battery technology as a energy storage system especially for Light Electric Vehicle (LEV) and electric vehicles (EV) applications. The R&D trend in the lithium?ion battery development is toward the high power and energy density cheaper in price and high safety standard. In our laboratory the research and development of lithium?ion battery technology was mainly focus to develop high power density performance of cathode material which is focusing to the Li?metal?oxide system LiMO 2 where M=Co Ni Mn and its combination. The nano particle size material which has irregular particle shape and high specific surface area was successfully synthesized by self propagating combustion technique. As a result the energy density and power density of the synthesized materials are significantly improved. In addition we also developed variety of sizes of lithium?ion battery prototype including (i) small size for electronic gadgets such as mobile phone and PDA applications (ii) medium size for remote control toys and power tools applications and (iii) battery module for high power application such as electric bicycle and electric scooter applications. The detail performance of R&D in advanced materials and prototype development in AMREC SIRIM Berhad will be discussed in this paper.

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.

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.

Science Journals Connector (OSTI)

The polyethylene (PE)-supported polymer membranes based on the blended polyvinylidene fluoride (PVDF) and cellulose acetate butyrate (CAB) are prepared for gel polymer electrolyte (GPE) of lithium ion battery. The performances of the prepared membranes and the resulting \\{GPEs\\} are investigated by scanning electron microscopy, electrochemical impedance spectroscopy, linear potential sweep, and charge–discharge test. The effect of the ratio of PVDF to CAB on the performance of the prepared membranes is considered. It is found that the GPE based on the blended polymer with PVDF:CAB = 2:1 (in weight) has the largest ionic conductivity (2.48 × 10?3 S cm?1) and shows good compatibility with anode and cathode of lithium ion battery. The LiCoO2/graphite battery using this GPE exhibits superior cyclic stability at room temperature, storage performance at elevated temperature, and rate performance.

Advanced Surface and Microstructural Characterization of Natural Graphite Anodes for Lithium Ion Batteries  

SciTech Connect (OSTI)

Natural graphite powders were subjected to a series of thermal treatments in order to improve the anode irreversible capacity loss (ICL) and capacity retention during long-term cycling of lithium ion batteries. A baseline thermal treatment in inert Ar or N2 atmosphere was compared to cases with a proprietary additive to the furnace gas environment. This additive substantially altered the surface chemistry of the natural graphite powders and resulted in significantly improved long-term cycling performance of the lithium ion batteries over the commercial natural graphite baseline. Different heat-treatment temperatures were investigated ranging from 950-2900 C with the intent of achieving the desired long-term cycling performance with as low of a maximum temperature and thermal budget as possible. A detailed summary of the characterization data is also presented, which includes X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and temperature-programed desorption mass spectroscopy (TPD-MS). This characterization data was correlated to the observed capacity fade improvements over the course of long-term cycling at high charge-discharge rates in full lithium-ion coin cells. It is believed that the long-term performance improvements are a result of forming a more stable solid electrolyte interface (SEI) layer on the anode graphite surfaces, which is directly related to the surface chemistry modifications imparted by the proprietary gas environment during thermal treatment.

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.

Abstract Carbon aerogel (CA) with 3-D continuous skeleton and mesopore structure was prepared via a microemulsion-templated sol–gel polymerization method and then used as the anode materials of lithium-ion batteries. It was found that the reversible specific capacity of the as-prepared \\{CAs\\} could stay at about 470 mA h g?1 for 80 cycles, much higher than the theoretical capacity of commercial graphite (372 mAh g?1). In addition, CA also showed a better rate capacity compared to commercial graphite. The good electrochemical properties could be ascribed to the following three factors: (1) the large BET surface area of 620 m2 g?1, which can provide more lithium ion insertion sites, (2) 3-D continuous skeleton of CAs, which favors the transport of the electrons, (3) 3-D continuous mesopore structure with narrow mesopore size distribution and high mesopore ratio of 87.3%, which facilitates the diffusion and transport of the electrolyte and lithium ions.

The Application of Synchrotron Techniques to the Study of Lithium-ion Batteries  

SciTech Connect (OSTI)

This paper gives a brief review of the application of synchrotron X-ray techniques to the study of lithium-ion battery materials. The two main techniques are X-ray absorption spectroscopy (XAS) and high-resolution X-ray diffraction (XRD). Examples are given for in situ XAS and XRD studies of lithium-ion battery cathodes during cycling. This includes time-resolved methods. The paper also discusses the application of soft X-ray XAS to do ex situ studies on battery cathodes. By applying two signal detection methods, it is possible to probe the surface and the bulk of cathode materials simultaneously. Another example is the use of time-resolved XRD studies of the decomposition of reactions of charged cathodes at elevated temperatures. Measurements were done both in the dry state and in the presence of electrolyte. Brief reports are also given on two new synchrotron techniques. One is inelastic X-ray scattering, and the other is synchrotron X-ray reflectometry studies of the surface electrode interface (SEI) on highly oriented single crystal lithium battery cathode surfaces.

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.

Pulsed laser deposited Si on multilayer graphene as anode material for lithium ion batteries  

Science Journals Connector (OSTI)

Pulsed laser deposition and chemical vapor deposition were used to deposit very thin silicon on multilayer graphene (MLG) on a nickel foam substrate for application as an anode material for lithium ion batteries. The as-grown material was directly fabricated into an anode without a binder and tested in a half-cell configuration. Even under stressful voltage limits that accelerate degradation the Si-MLG films displayed higher stability than Si-only electrodes. Post-cycling images of the anodes reveal the differences between the two material systems and emphasize the role of the graphene layers in improving adhesion and electrochemical stability of the Si.

Silicon nanoparticle and carbon nanotube loaded carbon nanofibers for use in lithium-ion battery anodes  

Science Journals Connector (OSTI)

Abstract In this report, we introduce electrospun silicon nanoparticle and carbon nanotube loaded carbon nanofibers (SCNFs) as anode materials in lithium-ion batteries (LIBs). The one-dimensional structure of electrospun nanofibers provides porosity for the anode material. Carbon nanotubes (CNTs) in the electrospun fibers reduce the volume expansion of silicon nanoparticles (SiNPs) and improve mechanical stability of the electrode. Both \\{CNTs\\} and carbon nanofibers enhance electronic conduction by connecting SiNPs in \\{SCNFs\\} for electrode reactions. These contribute to improved electrochemical performance of SCNF anode-based \\{LIBs\\} resulting in the enhancement of capacity and cycling ability.

Components were analyzed after cycling with electrochemical, Raman and TEM techniques to determine capacity fade mechanisms. The cells with carbon-coated current collectors in the cathode and LiBOB-salt electrolyte showed the best performance stability. In many cases, iron species were detected on the anodes removed from cells with both TEM and Raman spectroscopy. The LiFePO4 electrodes showed unchanged capacity suggesting that the iron is migrating in small quantities and is acting as a catalyst to destabilize the anode SEI in these 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.

Potential use of geothermal energy sources for the production of lithium-ion batteries  

Science Journals Connector (OSTI)

The lithium-ion battery is one of the most promising technologies for energy storage in many recent and emerging applications. However, the cost of lithium-ion batteries limits their penetration in the public market. Energy input is a significant cost driver for lithium batteries due to both the electrical and thermal energy required in the production process. The drying process requires 45–57% of the energy consumption of the production process according to a model presented in this paper. The model is used as a base for quantifying the energy and temperatures at each step, as replacing electric energy with thermal energy is considered. In Iceland, it is possible to use geothermal steam as a thermal resource in the drying process. The most feasible type of dryer and heating method for lithium batteries would be a tray dryer (batch) using a conduction heating method under vacuum operation. Replacing conventional heat sources with heat from geothermal steam in Iceland, we can lower the energy cost to 0.008USD/Ah from 0.13USD/Ah based on average European energy prices. The energy expenditure after 15 years operation could be close to 2% of total expenditure using this renewable resource, down from 12 to 15% in other European countries. According to our profitability model, the internal rate of return of this project will increase from 11% to 23% by replacing the energy source. The impact on carbon emissions amounts to 393.4–215.1 g/Ah lower releases of CO2 per year, which is only 2–5% of carbon emissions related to battery production using traditional energy sources.

Understanding the Degredation of Silicion Electrodes for Lithium Ion Batteries Using Acoustic Emission  

SciTech Connect (OSTI)

Silicon is a promising anode material for lithium ion battery application due to its high specific capacity, low cost, and abundance. However, when silicon is lithiated at room temperature it can undergo a volume expansion in excess of 280% which leads to extensive fracturing. This is thought to be a primary cause of the rapid decay in cell capacity routinely observed. Acoustic emission (AE) was employed to monitor activity in composite silicon electrodes while cycling in lithium ion half-cells using a constant current-constant voltage procedure. The major source of AE was identified as the brittle fracture of silicon particles resulting from the alloying reaction that gives rise to LixSi phases. The largest number of emissions occurred on the first lithiation corresponding to surface fracture of the silicon particles, followed by distinct emission bursts on subsequent charge and discharge steps. Furthermore, a difference in the average parameters describing emission during charge and discharge steps was observed. Potential diagnostic and materials development applications of the presented AE techniques are discussed.

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.

Electrospun carboxymethyl cellulose acetate butyrate (CMCAB) nanofiber for high rate lithium-ion battery  

Science Journals Connector (OSTI)

Abstract Cellulose derivative CMCAB was synthesized, and nanometer fiber composite material was obtained from lithium iron phosphate (LiFePO4, LFP)/CMCAB by electrospinning. Under the protection of inert gas, modified LFP/carbon nanofibers (CNF) nanometer material was obtained by carbonization in 600 °C. IR, TG-DSC, SEM and EDS were performed to characterize their morphologies and structures. LFP/CNF composite materials were assembled into lithium-ion battery and tested their performance. Specific capacity was increased from 147.6 mAh g?1 before modification to 160.8 mAh g?1 after modification for the first discharge at the rate of 2 C. After 200 charge–discharge cycles, when discharge rate was increased from 2 C to 5 C to 10 C, modified battery capacity was reduced from 152.4 mAh g?1 to 127.9 mAh g?1 to 106 mAh g?1. When the ratio was reduced from 10 C to 5 C to 2 C, battery capacity can be quickly approximate to the original level. Cellulose materials that were applied to lithium battery can improve battery performance by electrospinning.

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.

Nanostructured lithium-aluminum alloy electrodes for lithium-ion batteries.  

SciTech Connect (OSTI)

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach theoretical capacity for the formation of LiAl (1 Ah/g). The performance of electrodeposited aluminum films is dependent on film thickness, with thicker films exhibiting better cycling behavior. The same trend is shown for electron-beam deposited aluminum films, suggesting that aluminum film thickness is the major determinant in electrochemical performance regardless of deposition technique. Synthesis of aluminum nanorod arrays on stainless steel substrates is demonstrated using electrodeposition into anodic aluminum oxide templates followed by template dissolution. Unlike nanostructures of other lithium-alloying materials, the electrochemical performance of these aluminum nanorod arrays is worse than that of bulk aluminum.

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.

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.

Interface Modifications by Anion Acceptors for High Energy Lithium Ion Batteries  

SciTech Connect (OSTI)

Li-rich, Mn-rich (LMR) layered composite, for example, Li[Li0.2Ni0.2Mn0.6]O2, has attracted extensive interests because of its highest energy density among all cathode candidates for lithium ion batteries (LIB). However, capacity degradation and voltage fading are the major challenges associated with this series of layered composite, which plagues its practical application. Herein, we demonstrate that anion receptor, tris(pentafluorophenyl)borane ((C6F5)3B, TPFPB), substantially enhances the cycling stability and alleviates the voltage degradation of LMR. In the presence of 0.2 M TPFPB, Li[Li0.2Ni0.2Mn0.6]O2 shows capacity retention of 81% after 300 cycles. It is proposed that TPFPB effectively confines the highly active oxygen species released from structural lattice through its strong coordination ability and high oxygen solubility. The electrolyte decomposition caused by the oxygen species attack is therefore largely mitigated, forming reduced amount of byproducts on the cathode surface. Additionally, other salts such as insulating LiF derived from electrolyte decomposition are also soluble in the presence of TPFPB. The collective effects of TPFPB mitigate the accumulation of parasitic reaction products and stabilize the interfacial resistances between cathode and electrolyte during extended cycling, thus significantly improving the cycling performance of Li[Li0.2Ni0.2Mn0.6]O2.

Calendar Life Studies of Advanced Technology Development Program Gen 1 Lithium Ion Batteries  

SciTech Connect (OSTI)

This report presents the test results of a special calendar-life test conducted on 18650-size, prototype, lithium-ion battery cells developed to establish a baseline chemistry and performance for the Advanced Technology Development Program. As part of electrical performance testing, a new calendar-life test protocol was used. The test consisted of a once-per-day discharge and charge pulse designed to have minimal impact on the cell yet establish the performance of the cell over a period of time such that the calendar life of the cell could be determined. The calendar life test matrix included two states of charge (i.e., 60 and 80%) and four temperatures (40, 50, 60, and 70°C). Discharge and regen resistances were calculated from the test data. Results indicate that both discharge and regen resistance increased nonlinearly as a function of the test time. The magnitude of the discharge and regen resistance depended on the temperature and state of charge at which the test was conducted. The calculated discharge and regen resistances were then used to develop empirical models that may be useful to predict the calendar life or the cells.

Graphene/silicon nanocomposite anode with enhanced electrochemical stability for lithium-ion battery applications  

Science Journals Connector (OSTI)

Abstract A graphene/silicon nanocomposite has been synthesized, characterized and tested as anode active material for lithium-ion batteries. A morphologically stable composite has been obtained by dispersing silicon nanoparticles in graphene oxide, previously functionalized with low-molecular weight polyacrylic acid, in eco-friendly, low-cost solvent such as ethylene glycol. The use of functionalized graphene oxide as substrate for the dispersion avoids the aggregation of silicon particles during the synthesis and decreases the detrimental effect of graphene layers re-stacking. Microwave irradiation of the suspension, inducing reduction of graphene oxide, and the following thermal annealing of the solid powder obtained by filtration, yield a graphene/silicon composite material with optimized morphology and properties. Composite anodes, prepared with high-molecular weight polyacrylic acid as green binder, exhibited high and stable reversible capacity values, of the order of 1000 mAh g?1, when cycled using vinylene carbonate as electrolyte additive. After 100 cycles at a current of 500 mA g?1, the anode showed a discharge capacity retention of about 80%. The mechanism of reversible lithium uptake is described in terms of Li–Si alloying/dealloying reaction. Comparison of the impedance responses of cells tested in electrolytes with or without vinylene carbonate confirms the beneficial effects of the additive in stabilizing the composite anode.

Hard Carbon Wrapped in Graphene Networks as Lithium Ion Battery Anode  

Science Journals Connector (OSTI)

Abstract Hard carbon enveloped with graphene networks was fabricated by a facile and scalable method. In the constructed architecture, hard carbon offers large lithium storage and flexible graphene layers can provide a highly conductive matrix for enabling good contact between particles and facilitate the diffusion and transport of electrons and ions. As a consequence, the hybrid anode exhibits enhanced reversible capacity (500 mAh g?1 at current density of 20 mA g?1), rate capability (400 mAh g?1 at 0.2 C, 290 mAh g?1 at 1 C, 250 mAh g?1 at 2 C, and 200 mAh g?1 at 5 C, 1C = 400 mA g?1) and cycle performance. We believe that the outstanding synergetic effect between the graphene networks and the hard carbon structures induces the superior lithium storage performance of the overall electrode by maximally utilizing the electrochemically active graphene and hard carbon particles. As far as we know, the hard carbon/graphene hybrids were firstly fabricated as anode in lithium-ion batteries.

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.

Enhances the Performance of Enhances the Performance of a Lithium-Ion Battery Cathode Scientists from NREL and the University of Toledo have combined theoretical and experimental studies to demonstrate a promising approach to significantly enhance the performance of lithium iron phosphate (LiFePO 4 ) cathodes for lithium-ion batteries. In the most common commercial design for lithium-ion (Li-ion) batteries, the positive electrode or cathode is lithium cobalt oxide (LiCoO 2 ). This material exhibits high electrical conductivity, meaning that it can transport electrons very effectively. However, the cobalt in LiCoO 2 has at least two detrimental characteristics-it is relatively expensive, which leads to higher battery costs, and it is toxic, which poses potential environmental and safety issues.

Recovery of lithium and cobalt from waste lithium ion batteries of mobile phone  

SciTech Connect (OSTI)

Graphical abstract: Recovery of valuable metals from scrap batteries of mobile phone. - Highlights: • Recovery of Co and Li from spent LIBs was performed by hydrometallurgical route. • Under the optimum condition, 99.1% of lithium and 70.0% of cobalt were leached. • The mechanism of the dissolution of lithium and cobalt was studied. • Activation energy for lithium and cobalt were found to be 32.4 kJ/mol and 59.81 kJ/mol, respectively. • After metal recovery, residue was washed before disposal to the environment. - Abstract: In view of the stringent environmental regulations, availability of limited natural resources and ever increasing need of alternative energy critical elements, an environmental eco-friendly leaching process is reported for the recovery of lithium and cobalt from the cathode active materials of spent lithium-ion batteries of mobile phones. The experiments were carried out to optimize the process parameters for the recovery of lithium and cobalt by varying the concentration of leachant, pulp density, reductant volume and temperature. Leaching with 2 M sulfuric acid with the addition of 5% H{sub 2}O{sub 2} (v/v) at a pulp density of 100 g/L and 75 °C resulted in the recovery of 99.1% lithium and 70.0% cobalt in 60 min. H{sub 2}O{sub 2} in sulfuric acid solution acts as an effective reducing agent, which enhance the percentage leaching of metals. Leaching kinetics of lithium in sulfuric acid fitted well to the chemical controlled reaction model i.e. 1 ? (1 ? X){sup 1/3} = k{sub c}t. Leaching kinetics of cobalt fitted well to the model ‘ash diffusion control dense constant sizes spherical particles’ i.e. 1 ? 3(1 ? X){sup 2/3} + 2(1 ? X) = k{sub c}t. Metals could subsequently be separated selectively from the leach liquor by solvent extraction process to produce their salts by crystallization process from the purified solution.

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.

High energy spinel-structured cathode stabilized by layered materials for advanced lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract Due to well-known Jahn–Teller distortion in spinel LiMn1.5Ni0.5O4, it can only be reversibly electrochemically cycled between 3 and 4.8 V with a limited reversible capacity of ?147 mAh g?1. This study intends to embed the layer-structured Li2MnO3 nanodomains into LiMn1.5Ni0.5O4 spinel matrix so that the Jahn–Teller distortion can be suppressed even when the average Mn oxidation state is below +3.5. A series of xLi2MnO3·(1 ? x)LiMn1.5Ni0.5O4 where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5 and 1 are synthesized by co-precipitation method. The composites with intermediate values of x = 0.1, 0.2, 0.3, 0.4 and 0.5 exhibit both spinel and layered structural domains in the particles and show greatly improved cycle stability than that of the pure spinel. Among them, 0.3Li2MnO3·0.7LiMn1.5Ni0.5O4 delivers the highest and almost constant capacity after a few conditional cycles and shows superior cycle stability. Ex-situ X-ray diffraction results indicate that no Jahn–Teller distortion occurs during the cycling of the 0.3Li2MnO3·0.7LiMn1.5Ni0.5O4 composite. Additionally, 0.3Li2MnO3·0.7LiMn1.5Ni0.5O4 possesses a high energy density of ?700 Wh kg?1, showing great promise for advanced high energy density lithium-ion batteries.

Performance improvement of phenyl acetate as propylene carbonate-based electrolyte additive for lithium ion battery by fluorine-substituting  

Science Journals Connector (OSTI)

Abstract Phenyl acetate (PA) is more stable and much cheaper than vinylene carbonate (VC), a commercial electrolyte additive for graphite anode of lithium ion battery, but its performance needs to be improved. In this paper, we report a new additive, 4-fluorophenyl acetate (4-FPA), which results from the fluorine-substituting of PA. The properties of the formed solid electrolyte interphase (SEI) by 4-FPA are investigated comparatively with PA by molecular energy level calculation, cyclic voltammetry, charge–discharge test, scanning electron microscopy, energy dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. It is found that the SEI formed by 4-FPA is more protective than PA, resulting in the improved cyclic stability of lithium ion battery: the capacity retention of LiFePO4/graphite cell after 90 cycles is 92% for 4-FPA but only 84% for PA. The fluorine in 4-FPA makes it more reducible than PA and the fluorine-containing reduction products of 4-FPA are incorporated into the SEI, which contributes to the improved performance.

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.

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.

Self-assembled porous MoO2/graphene microspheres towards high performance anodes for lithium ion batteries  

Science Journals Connector (OSTI)

Abstract Three dimensional (3D) porous self-assembled MoO2/graphene microspheres are successfully synthesized via microwave-assisted hydrothermal process in a short reaction time followed by thermal annealing. Such rationally designed multifunctional hybrid nanostructure is constructed from interconnected MoO2 nanoparticles (3–5 nm), which is self-assembled into ordered nanoporous microspheres via strong electrostatic attraction between graphene sheets and MoO2 nanoparticles. The MoO2/graphene hybrid structure delivers a high reversible capacity with significantly enhanced cycling stability (?1300 mAh g?1 after 80 cycles at C/10 rate) and excellent rate capability (913 and 390 mAh g?1 at 2C and 5C rates, respectively), when used as an anode material. The microspheres are interconnected and well encapsulated by the flexible graphene sheets, which not only accommodates large volume change but also increases the electrical conductivity of the hybrid structure. Moreover, nanoporous voids present in the 3D framework facilitate effective electrolyte penetration and make a direct contact with the active MoO2 nanoparticles, thereby greatly enhancing lithium ion transport. The strategic combination of self-assembly, nanoporous voids, 3D network and intriguing properties of graphene sheets provides excellent electrochemical performance as anode materials for Lithium ion battery applications.

Science Journals Connector (OSTI)

Abstract MnO and nitrogen-doped carbon (N-C) nanocomposites have been successfully synthesized by a facile thermal-decomposing method using the mixture of glycine and manganese acetate as precursor. As anode material for lithium-ion batteries (LIBs), electrochemical results show that the as-prepared MnO/N-C achieves a reversible capacity of 473 mAh g?1 after 50 cycles at a current density of 100 mA g?1 and the capacities of 631.4, 547.7, 443.1, 294.7, and 161.8 mAh g?1 at the current densities of 100, 200, 400, 800, and 1600 mA g?1, respectively. The superior cycling and rate performances is attributed to the nanocomposite structure, in which nanosized MnO particles shorten the diffusion path of lithium ions and the N-doped carbon cushions the volume change and improves the electronic conductivity of electrode.

STUDIES ON TWO CLASSES OF POSITIVE ELECTRODE MATERIALS FOR LITHIUM-ION BATTERIES  

SciTech Connect (OSTI)

The development of advanced lithium-ion batteries is key to the success of many technologies, and in particular, hybrid electric vehicles. In addition to finding materials with higher energy and power densities, improvements in other factors such as cost, toxicity, lifetime, and safety are also required. Lithium transition metal oxide and LiFePO{sub 4}/C composite materials offer several distinct advantages in achieving many of these goals and are the focus of this report. Two series of layered lithium transition metal oxides, namely LiNi{sub 1/3}Co{sub 1/3-y}M{sub y}Mn{sub 1/3}O{sub 2} (M=Al, Co, Fe, Ti) and LiNi{sub 0.4}Co{sub 0.2-y}M{sub y}Mn{sub 0.4}O{sub 2} (M = Al, Co, Fe), have been synthesized. The effect of substitution on the crystal structure is related to shifts in transport properties and ultimately to the electrochemical performance. Partial aluminum substitution creates a high-rate positive electrode material capable of delivering twice the discharge capacity of unsubstituted materials. Iron substituted materials suffer from limited electrochemical performance and poor cycling stability due to the degradation of the layered structure. Titanium substitution creates a very high rate positive electrode material due to a decrease in the anti-site defect concentration. LiFePO{sub 4} is a very promising electrode material but suffers from poor electronic and ionic conductivity. To overcome this, two new techniques have been developed to synthesize high performance LiFePO{sub 4}/C composite materials. The use of graphitization catalysts in conjunction with pyromellitic acid leads to a highly graphitic carbon coating on the surface of LiFePO{sub 4} particles. Under the proper conditions, the room temperature electronic conductivity can be improved by nearly five orders of magnitude over untreated materials. Using Raman spectroscopy, the improvement in conductivity and rate performance of such materials has been related to the underlying structure of the carbon films. The combustion synthesis of LiFePO4 materials allows for the formation of nanoscale active material particles with high-quality carbon coatings in a quick and inexpensive fashion. The carbon coating is formed during the initial combustion process at temperatures that exceed the thermal stability limit of LiFePO{sub 4}. The olivine structure is then formed after a brief calcination at lower temperatures in a controlled environment. The carbon coating produced in this manner has an improved graphitic character and results in superior electrochemical performance. The potential co-synthesis of conductive carbon entities, such as carbon nanotubes and fibers, is also briefly discussed.

Material and energy flows in the materials production, assembly, and end-of-life stages of the automotive lithium-ion battery life cycle  

SciTech Connect (OSTI)

This document contains material and energy flows for lithium-ion batteries with an active cathode material of lithium manganese oxide (LiMn{sub 2}O{sub 4}). These data are incorporated into Argonne National Laboratory's Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model, replacing previous data for lithium-ion batteries that are based on a nickel/cobalt/manganese (Ni/Co/Mn) cathode chemistry. To identify and determine the mass of lithium-ion battery components, we modeled batteries with LiMn{sub 2}O{sub 4} as the cathode material using Argonne's Battery Performance and Cost (BatPaC) model for hybrid electric vehicles, plug-in hybrid electric vehicles, and electric vehicles. As input for GREET, we developed new or updated data for the cathode material and the following materials that are included in its supply chain: soda ash, lime, petroleum-derived ethanol, lithium brine, and lithium carbonate. Also as input to GREET, we calculated new emission factors for equipment (kilns, dryers, and calciners) that were not previously included in the model and developed new material and energy flows for the battery electrolyte, binder, and binder solvent. Finally, we revised the data included in GREET for graphite (the anode active material), battery electronics, and battery assembly. For the first time, we incorporated energy and material flows for battery recycling into GREET, considering four battery recycling processes: pyrometallurgical, hydrometallurgical, intermediate physical, and direct physical. Opportunities for future research include considering alternative battery chemistries and battery packaging. As battery assembly and recycling technologies develop, staying up to date with them will be critical to understanding the energy, materials, and emissions burdens associated with batteries.

Abstract Lithium-ion battery (LIB) technology is currently the most important and promising energy storage technology that has captured the portable electronic market, invaded the power tool equipment market, and penetrated the electric vehicle market. The ever-growing demand for its energy capacity necessitates the understanding of (de)lithiation mechanism on a nanoscale, and thus the development of platforms enabling in-situ electrochemical TEM characterization. Sealed liquid cell (SLC) device has been widely recognized as the most desirable platform, since it allows the introduction of commercial volatile electrolytes into TEM. However, a comprehensive review summarizing the current development of \\{SLCs\\} for in-situ TEM LIB research is missing and in urgent need for its benign development.

Abstract Tin dioxide nanoparticles on nitrogen doped graphene aerogel (SnO2-NGA) hybrid are synthesized by one-step hydrothermal method and successfully applied in lithium-ion batteries as a free-standing anode. The electrochemical performance of SnO2-NGA hybrid is investigated by galvanostatic charge–discharge cycling, rate capability test, cyclic voltammetry and electrochemical impedance spectroscopy. It is found that the SnO2-NGA hybrid with freestanding spongy-like structure exhibit remarkable lithium storage capacity (1100 mAh g?1 after 100 cycles), good cycling stability and high rate capability. The outstanding performance is attributed to the uniform SnO2 nanoparticles, unique spongy-like structure and N doping defect for Li+ diffusion.

Gram-Scale Synthesis of Graphene-Mesoporous SnO2 Composite as Anode for Lithium-ion Batteries  

Science Journals Connector (OSTI)

Abstract The gram-scale synthesis of graphene based mesoporous SnO2 composite (G-M-SnO2) has been successfully realized based on kirkendall effect. When used as anode for lithium ion batteries, it delivers a high reversible capacity of 1354 mAhg?1 after 50 cycles at 100 mAg?1 and excellent rate capability of 664 mAhg?1 at 2 Ag?1. The outstanding lithium storage performance mainly results from the synergistic effect of the ultrasmall SnO2 and conductive graphene nanoparticles, which not only enhanced the conductivity of the whole electrode but also provide buffer matrix for the expansion of SnO2 nanoparticles during charge-discharge process. Furthermore, the ultra-small size of SnO2 shortens the diffusion length of Li+/e? in SnO2.

Hierarchical mesoporous/microporous carbon with graphitized frameworks for high-performance lithium-ion batteries  

SciTech Connect (OSTI)

A hierarchical meso-/micro-porous graphitized carbon with uniform mesopores and ordered micropores, graphitized frameworks, and extra-high surface area of ?2200 m{sup 2}/g, was successfully synthesized through a simple one-step chemical vapor deposition process. The commercial mesoporous zeolite Y was utilized as a meso-/ micro-porous template, and the small-molecule methane was employed as a carbon precursor. The as-prepared hierarchical meso-/micro-porous carbons have homogeneously distributed mesopores as a host for electrolyte, which facilitate Li{sup +} ions transport to the large-area micropores, resulting a high reversible lithium ion storage of 1000 mA h/g and a high columbic efficiency of 65% at the first cycle.

Composition-tailored synthesis of gradient transition metal precursor particles for lithium-ion battery cathode materials.  

SciTech Connect (OSTI)

We report the tailored synthesis of particles with internal gradients in transition metal composition aided by the use of a general process model. Tailored synthesis of transition metal particles was achieved using a coprecipitation reaction with tunable control over the process conditions. Gradients in the internal composition of the particles was monitored and confirmed experimentally by analysis of particles collected during regularly timed intervals. Particles collected from the reactor at the end of the process were used as the precursor material for the solid-state synthesis of Li{sub 1.2}(Mn{sub 0.62}Ni{sub 0.38}){sub 0.8}O{sub 2}, which was electrochemically evaluated as the active cathode material in a lithium battery. The Li{sub 1.2}(Mn{sub 0.62}Ni{sub 0.38}){sub 0.8}O{sub 2} material was the first example of a structurally integrated multiphase material with a tailored internal gradient in relative transition metal composition as the active cathode material in a lithium-ion battery. We believe our general synthesis strategy may be applied to produce a variety of new cathode materials with tunable interior, surface, and overall relative transition metal compositions.

Tailored Recovery of Carbons from Waste Tires for Enhanced Performance as Anodes in Lithium-ion Batteries  

SciTech Connect (OSTI)

Morphologically tailored pyrolysis-recovered carbon black is utilized in lithium-ion batteries as a potential solution for adding value to waste tire-rubber-derived materials. Micronized tire rubber was digested in a hot oleum bath to yield a sulfonated rubber slurry that was then filtered, washed, and compressed into a solid cake. Carbon was recovered from the modified rubber cake by pyrolysis in a nitrogen atmosphere. The chemical pretreatment of rubber produced a carbon monolith with higher yield than that from the control (a fluffy tire-rubber-derived carbon black). The carbon monolith showed a very small volume fraction of pores of widths 3 4 nm, reduced specific surface area, and an ordered assembly of graphitic domains. Electrochemical studies on the recovered-carbon-based anode revealed an improved Li-ion battery performance with higher reversible capacity than that of commercial carbon materials. Anodes made with a sulfonated tire-rubber-derived carbon and a control tire-rubber-derived carbon, respectively, exhibited an initial coulombic efficiency of 80% and 45%, respectively. The reversible capacity of the cell with the sulfonated carbon as anode was 400 mAh/g after 100 cycles, with nearly 100% coulombic efficiency. Our success in producing higher performance carbon material from waste tire rubber for potential use in energy storage applications adds a new avenue to tire rubber recycling.

In-Situ Transmission Electron Microscopy Probing of Native Oxide and Artificial Layers on Silicon Nanoparticles for Lithium Ion Batteries  

SciTech Connect (OSTI)

Surface modification of silicon nanoparticle via molecular layer deposition (MLD) has been recently proved to be an effective way for dramatically enhancing the cyclic performance in lithium ion batteries. However, the fundamental mechanism as how this thin layer of coating function is not known, which is even complicated by the inevitable presence of native oxide of several nanometers on the silicon nanoparticle. Using in-situ TEM, we probed in detail the structural and chemical evolution of both uncoated and coated silicon particles upon cyclic lithiation/delithation. We discovered that upon initial lithiation, the native oxide layer converts to crystalline Li2O islands, which essentially increases the impedance on the particle, resulting in ineffective lithiation/delithiation, and therefore low coulombic efficiency. In contrast, the alucone MLD coated particles show extremely fast, thorough and highly reversible lithiation behaviors, which are clarified to be associated with the mechanical flexibility and fast Li+/e- conductivity of the alucone coating. Surprisingly, the alucone MLD coating process chemically changes the silicon surface, essentially removing the native oxide layer and therefore mitigates side reaction and detrimental effects of the native oxide. This study provides a vivid picture of how the MLD coating works to enhance the coulombic efficiency and preserve capacity and clarifies the role of the native oxide on silicon nanoparticles during cyclic lithiation and delithiation. More broadly, this work also demonstrated that the effect of the subtle chemical modification of the surface during the coating process may be of equal importance as the coating layer itself.

Spinel LiMn(2)O(4)/Reduced Graphene Oxide Hybrid for High Rate Lithium Ion Batteries  

SciTech Connect (OSTI)

A well-crystallized and nano-sized spinel LiMn{sub 2}O{sub 4}/reduced graphene oxide hybrid cathode material for high rate lithium-ion batteries has been successfully synthesized via a microwave-assisted hydrothermal method at 200 C for 30 min without any post heat-treatment. The nano-sized LiMn{sub 2}O{sub 4} particles were evenly dispersed on the reduced graphene oxide template without agglomeration, which allows the inherent high active surface area of individual LiMn{sub 2}O{sub 4} nanoparticles in the hybrid. These unique structural and morphological properties of LiMn{sub 2}O{sub 4} on the highly conductive reduced graphene oxide sheets in the hybrid enable achieving the high specific capacity, an excellent high rate capability and stable cycling performance. An analysis of the cyclic voltammogram data revealed that a large surface charge storage contribution of the LiMn{sub 2}O{sub 4}/reduced graphene oxide hybrid plays an important role in achieving faster charge/discharge.

Significant influence of insufficient lithium on electrochemical performance of lithium-rich layered oxide cathodes for lithium ion batteries  

Science Journals Connector (OSTI)

Abstract With an aim to broaden the understanding of the factors that govern electrochemical performance of lithium-rich layered oxide, the influences of insufficient lithium on reversible capacity, cyclic stability and rate capability of the oxide as cathode of lithium ion battery are investigated in this study. Various concentrations of lithium precursor are introduced to synthesize a target composition Li[Li0.13Ni0.30Ni0.57]O2, and the resulting products are characterized with inductively coupled plasma spectrum, scanning electron microscope, X-ray diffraction, Raman spectroscopy, and electrochemical measurements. The results indicate that the lithium content in the resulting oxide decreases with reducing the concentration of lithium precursor from 10wt%-excess lithium to stoichiometric lithium, due to insufficient compensation for lithium volatilization during synthesis process at high temperature. However, all these oxides still exhibit typically structural and electrochemical characteristics of lithium-rich layered oxides. Interestingly, with decreasing the Li content in the oxide, its reversible capacity increases due to relatively higher content of active transition-metal ions, while the cyclic stability degrades severely because of structural instability induced by higher content of Mn3+ ions and deeper lithium extraction.

Li3V2(PO4)3/graphene nanocomposite as a high performance cathode material for lithium ion battery  

Science Journals Connector (OSTI)

Abstract In this work, pure LVP nanoparticles and an LVP/graphene nanocomposite are successfully synthesized by a simple and cost effective polyol based solvothermal method, which can be easily scaled up. The synthesized nanocomposite contained small (30–60 nm) LVP nanoparticles completely and uniformly anchored on reduced graphene nanosheets. As a cathode for lithium ion batteries, the nanocomposite electrode delivered high reversible lithium storage capacity (189.8 mA h g?1 at 0.1 C), superior cycling stability (111.8 mA h g?1 at 0.1 C, 112.6 mA h g?1 at 5 C, and 103.4 mA h g?1 at 10 C after 80 cycles) and better C-rate capability (90.8 mA h g?1 at 10 C), whereas the pure LVP nanoparticles electrode delivered much less capacity at all investigated current rates. The enhanced electrochemical performance of the nanocomposite electrode can be attributed to the synergistic interaction between the uniformly dispersed LVP nanoparticles and the graphene nanosheets, which offers a large number of accessible active sites for the fast diffusion of Li ions, low internal resistance, high conductivity and more importantly, accommodates the large volume expansion/contraction during cycling.

Co3O4 nanocubes homogeneously assembled on few-layer graphene for high energy density lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract Graphene-based nanocomposites have been synthesized and tested as electrode materials for high power lithium-ion batteries. In the synthesis of such nanocomposites, graphene is generally introduced by either thermally or chemically reduced graphite oxide (GO), which has poorer electric conductivity and crystallinity than mechanically exfoliated graphene. Here, we prepare few-layer graphene sheet (FLGS) with high electric conductivity, by sonicating expanded graphite in DMF solvent, and develop a simple one-pot hydrothermal method to fabricate monodispersed and ultrasmall Co3O4 nanocubes (about 4 nm in size) on the FLGS. This composite, consisting of homogeneously assembled and high crystalline Co3O4 nanocubes on the FLGS, has shown higher capacity and much better cycling stability than counterparts synthesized using GO as a precursor. The products in different synthesis stages have been characterized by TEM, FTIR and XPS to investigate the nanocube growth mechanism. We find that Co(OH)2 initially grew homogeneously on the graphene surface, then gradually oxidized to form Co3O4 nanoparticle seeds, and finally converted to Co3O4 nanocubes with caboxylated anion as surfactant. This work explores the mechanism of nanocrystal growth and its impact on electrochemical properties to provide further insights into the development of nanostructured electrode materials for high power energy storage.

Embedding nano-silicon in graphene nanosheets by plasma assisted milling for high capacity anode materials in lithium ion batteries  

Science Journals Connector (OSTI)

Abstract The lithium storage performance of silicon (Si) is improved substantially by forming composite of nano-Si particles embedded homogeneously in graphene nanosheets (GNs) using a simple discharge plasma assisted milling (P-milling) method. The synergistic effect of the rapid heating of the plasma and the mechanical ball mill grinding with nano-Si as nanomiller converted the graphite powder to \\{GNs\\} with the integration of nano-Si particles in the in-situ formed GNs. This composite structure inhibits the agglomeration of nano-Si and improves electronic conductivity. The cycling stability and rate capability are enhanced, with a stable reversible capacity of 976 mAhg?1 at 50 mAg?1 for the P-milled 20 h nano-Si/GNs composite. A full cell containing a commercial LiMn2O4 cathode is assembled and demonstrated a satisfying utilization of the P-milled nano-Si/GNs composite anode with stable working potential. This composite shows promise for application in lithium ion batteries.

Long-life and high-rate LiVPO4F/C nanocrystals modified with graphene as cathode material for lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract Graphene modified LiVPO4F/C nanocomposite has been firstly investigated as cathode material for lithium-ion batteries. The LiVPO4F/C nanocrystals embedded on reduced graphene oxide sheets are synthesized via a sol–gel method. The obtained sample of graphene modified LiVPO4F/C is studied comparatively with LiVPO4F/C by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectra and various electrochemical tests. The results reveal that the modification of LiVPO4F/C nanocrystals with graphene can form an effective conducting network, which can greatly improve the electronic conductivity and lithium ion transport. Thus, the as-synthesized nanocomposite exhibits excellent high-rate capability and cycling stability. In the voltage range of 3.0–4.5 V, the graphene modified LiVPO4F/C delivers a reversible discharge capacity of 151.6 (nearly to its theoretical capability of 156 mAhg? 1) and 147.8 mAhg? 1 at 0.1 and 0.5 C, respectively. It also achieves an improved cyclability with capacity retention ratio of 91.4% after 300 cycles at a higher rate of 10 C. Therefore, it is of great potential use as a cathode material in rechargeable lithium-ion batteries for hybrid-electric vehicles and electric vehicles.

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.

Molybdenum nitride/nitrogen-doped graphene hybrid material for lithium storage in lithium ion batteries  

Science Journals Connector (OSTI)

Abstract Molybdenum nitride and nitrogen-doped graphene nanosheets (MoN/GNS) hybrid materials are synthesized by a simple hydrothermal method combined with a heat treatment at 800 °C under an ammonia atmosphere. It is found by scanning and transmission electron microscopy that MoN nanoparticles ranging from 20 to 40 nm in diameter are homogeneously anchored to GNS. The electrochemical performance of MoN/GNS as a possible anode material for Li-ion batteries is investigated. Galvanostatic charge/discharge experiments reveal that the hybrid materials exhibit an enhanced lithium storage capacity and excellent rate capacity as a result of its efficient electronic and ionic mixed conducting network. The electrochemical results demonstrate that the weight ratio of GNS and MoN had significant effect on the electrochemical performance.

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.

Significant impact of 2D graphene nanosheets on large volume change tin-based anodes in lithium-ion batteries: A review  

Science Journals Connector (OSTI)

Abstract Sn-based materials have attracted much attention as anodes in lithium ion batteries (LIBs) due to their low cost, high theoretical capacities, and high energy density. However, their practical applications are limited by the poor cyclability originating from the huge volume changes. Graphene nanosheets (GNSs), a novel two-dimensional carbon sheet with one atom thickness and one of the thinnest materials, significantly address the challenges of Sn-based anodes as excellent buffering materials, showing great research interests in LIBs. In this review, various nanocomposites of GNSs/Sn-based anodes are summarized in detail, including binary and ternary composites.

Electrochemical performance of polyaniline coated LiMn{sub 2}O{sub 4} cathode active material for lithium ion batteries  

SciTech Connect (OSTI)

LiMn{sub 2}O{sub 4} compound are synthesized by combustion method using glycine as a fuel at temperature (T), 800°C which was coated by a polyaniline. The goal of this procedure is to promote better electronic conductivity of the LiMn{sub 2}O{sub 4} particles in order to improve their electrochemical performance for their application as cathodes in secondary lithium ion batteries. The structures of prepared products have been investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). To investigate the effect of polyaniline coating galvanostatic charge-discharge cycling (148 mA g{sup ?1}) studies are made in the voltage range of 3.5-4.5 V vs. Li at room temperature. Electrochemical performance of the LiMn{sub 2}O{sub 4} was significantly improved by the polaniline coating.

The development of low cost LiFePO4-based high power lithium-ion batteries  

SciTech Connect (OSTI)

The cycling performance of low-cost LiFePO4-based high-power lithium-ion cells was investigated and the components were analyzed after cycling to determine capacity fade mechanisms. Pouch type LiFePO4/natural graphite cells were assembled and evaluated by constant C/2 cycling, pulse-power and impedance measurements. From post-test electrochemical analysis after cycling, active materials, LiFePO4 and natural graphite, showed no degradation structurally or electrochemically. The main reasons for the capacity fade of cell were lithium inventory loss by side reaction and possible lithium deposition on the anode.

Co2SnO4 nanocrystals anchored on graphene sheets as high-performance electrodes for lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract Cubic spinel Co2SnO4/graphene sheets (Co2SnO4/G) nanocomposites are synthesized by a facile hydrothermal process in alkaline solution, using SnCl4 · 4H2O, CoCl2 · 6H2O and graphene oxide (GO) as the precursor. The structure and morphology of the resulting nanocomposites are characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Co2SnO4 nanoparticles are uniformly dispersed among graphene sheets, with a size of 80–150 nm. As anode material for lithium-ion batteries, the galvanostatic charge/discharge and cyclic voltammetry are conducted to indicate the electrochemical performance of Co2SnO4/G nanocomposites. Co2SnO4/G nanocomposites exhibit an improved electrochemical performance compared with pure Co2SnO4 nanoparticles, such as high reversible capacities, good cycling stability and excellent rate performance. The initial charge and discharge capacities are 996.1 mAh g?1 and 1424.8 mAh g?1. After 100 cycles, the reversible charge/discharge capacities still remain 1046/1061.1 mAh g?1 at the current density of 100 mA g?1. Co2SnO4 nanoparticles coated by Graphene sheets with superior electrochemical performance indicate that Co2SnO4/G nanocomposites are promising electrode materials used for high-storage lithium-ion batteries.

Synthesis and electrochemical performances of amorphous carbon-coated Sn-Sb particles as anode material for lithium-ion batteries  

SciTech Connect (OSTI)

The amorphous carbon coating on the Sn-Sb particles was prepared from aqueous glucose solutions using a hydrothermal method. Because the outer layer carbon of composite materials is loose cotton-like and porous-like, it can accommodate the expansion and contraction of active materials to maintain the stability of the structure, and hinder effectively the aggregation of nano-sized alloy particles. The as-prepared composite materials show much improved electrochemical performances as anode materials for lithium-ion batteries compared with Sn-Sb alloy and carbon alone. This amorphous carbon-coated Sn-Sb particle is extremely promising anode materials for lithium secondary batteries and has a high potentiality in the future use. - Graphical abstract: The amorphous carbon coating on the Sn-Sb particles was prepared from aqueous glucose solutions using a hydrothermal method.

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.

Poly vinyl acetate used as a binder for the fabrication of a LiFePO4-based composite cathode for lithium-ion batteries  

Science Journals Connector (OSTI)

ABSTRACT This paper describes a method for the preparation of composite cathodes for lithium ion-batteries by using poly vinyl acetate (PVAc) as a binder. \\{PVAc\\} is a non-fluorinated water dispersible polymer commonly used in a large number of industrial applications. The main advantages for using of this polymer are related to its low cost and negligible toxicity. Furthermore, since the \\{PVAc\\} is water processable, its use allows to replace the organic solvent, employed to dissolve the fluorinated polymer normally used as a binder in lithium battery technology, with water. In such a way it is possible to decrease the hazardousness of the preparation process as well as the production costs of the electrodes. In the paper the preparation, characterization and electrochemical performance of a LiFePO4 electrode based on \\{PVAc\\} as the binder is described. Furthermore, to assess the effect of the \\{PVAc\\} binder on the electrode properties, its performance is compared to that of a conventional electrode employing PVdF-HFP as a binder.

Self-supported poly(methyl methacrylate–acrylonitrile–vinyl acetate)-based gel electrolyte for lithium ion battery  

Science Journals Connector (OSTI)

Self-supported gel polymer electrolyte (GPE) was prepared based on copolymer, poly(methyl methacrylate–acrylonitrile–vinyl acetate) (P(MMA–AN–VAc)). The copolymer P(MMA–AN–VAc) was synthesized by emulsion polymerization and the copolymer membrane was prepared through phase inversion. The structure and the performance of the copolymer, the membrane and the GPE were characterized by FTIR, NMR, SEM, XRD, DSC/TG, LSV, CA, and EIS. It is found that the copolymer was formed through the breaking of double bond CC in each monomer. The membrane has low crystallinity and has low glass transition temperature, 39.1 °C, its thermal stability is as high as 310 °C, and its mechanical strength is improved compared with P(MMA–AN). The GPE is electrochemically stable up to 5.6 V (vs. Li/Li+) and its conductivity is 3.48 × 10?3 S cm?1 at ambient temperature. The lithium ion transference number in the GPE is 0.51 and the conductivity model of the GPE is found to obey the Vogel–Tamman–Fulcher (VTF) equation.

Hierarchical 3D micro-/nano-V2O5 (vanadium pentoxide) spheres as cathode materials for high-energy and high-power lithium ion-batteries  

Science Journals Connector (OSTI)

Abstract We facilely fabricate hierarchical 3D microspheres consisting of 2D V2O5 (vanadium pentoxide) nanosheets by a low temperature hydrothermal method and use it to structure hierarchical 3D micro-/nano-LIBs (lithium ion batteries) cathode. This is a template-free and facile method easy for scale-up production of hierarchical 3D micro-/nano-structured V2O5 spheres beneficial for high performance \\{LIBs\\} applications. Such a facile method resulted hierarchical 3D micro-/nano-V2O5 possess many unique features good for LIBs: (1) 2D V2O5 nanosheets facilitate the Li+ diffusions and electron transports; (2) hierarchical 3D micro-/nano-cathode structure built up by V2O5 nanosheet spheres will lead to the close and sufficient contact between electrolytes and activate materials and at the same time will create buffer volume to accommodate the volume change during discharging/charging process; and (3) micro-scale V2O5 spheres are easy to result in high cell packing density beneficial for high power battery. As revealed by the experimental results, the micro-/nano-V2O5 electrode demonstrates high initial discharge and charge capacities with no irreversible loss, high rate capacities at different currents and long-lasting lifespan. The high-energy and high-power performances of the micro-/nano-V2O5 electrode is ascribed to the unique hierarchical micro-/nano-structure merits of V2O5 spheres as abovementioned. In view of the advantages of facile fabrication method and unique features of 3D micro-/nano-V2O5 spheres for high power and high energy LIB battery, it is of great significance to beneficially broaden the applications of high-energy and high-power \\{LIBs\\} with creating novel hierarchical micro-/nano-structured V2O5 cathode materials.

Dense CoO/graphene stacks via self-assembly for improved reversibility as high performance anode in lithium ion batteries  

Science Journals Connector (OSTI)

Abstract Here, we propose a novel strategy to prepare dense stacks composed of alternating CoO and graphene layers for an anode in lithium ion batteries (LIBs), which contributes to enhanced stability and relatively large reversible capacity. This is accomplished by spontaneously pre-aligning negatively charged CoO-anchored graphene oxide (CG) and positively charged amine-functionalized graphene (GN) in an acidic medium, followed by thermal reduction. The performance of this product is contrasted with that of CG prepared under the identical conditions without the addition of GN, in which CoO nanoparticles are sandwiched between relatively loose and randomly oriented graphene stacks. For example, the composite delivers a capacity greater than 800 mAh g?1 with a fading rate of 0.04 mAh g?1 cycle?1 during 1000 charge/discharge (C/D) cycles at 1.0 A g?1, in contrast to ca. 400 mAh g?1 and 0.24 mAh g?1 cycle?1 for thermally reduced CG without the addition of GN. The origin of the superior electrochemical performance in the dense stacks is ascribed to the enhanced reversibility of a conversion reaction, which in turn contributes to a persistent formation/dissolution of gel-like polymer films (i.e., stable pseudo-capacitance). Experimental evidences that substantiate the aforementioned behaviors (improved reversibility for both processes) are presented.

A rapid microwave heating route to synthesize graphene modified LiFePO4/C nanocomposite for rechargeable lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract A simple and rapid method for synthesizing graphene modified LiFePO4/C nanocomposite has been developed for the first time by using a microwave heating. The obtained sample is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectra, Fourier transform infrared spectroscopy (FTIR) and various electrochemical testing techniques. XRD results indicate that the nanosized olivine LiFePO4/(C+graphene) is successfully synthesized. The size of as-synthesized nanoparticles can be controlled below 200 nm with good reproducibility through this route. TEM image shows that the LiFePO4/C nanoparticles are embedded in graphene sheets. The electrochemical performance results reveal that the modification of LiFePO4/C with graphene could construct an effective conducting network, which significantly enhance the properties of LiFePO4/C based composite, including high discharge capacity, stable cycle performance, good rate capability and small charge-transfer resistance. The excellent performance shows that the graphene modified LiFePO4/C synthesized via microwave heating is a promising cathode material for rechargeable lithium-ion batteries.

Sonochemical synthesis of SnO2/carbon nanotubes encapsulated in graphene sheets composites for lithium ion batteries with superior electrochemical performance  

Science Journals Connector (OSTI)

Abstract The SnO2/carbon nanotubes encapsulated in graphene sheets (CSGN) composites are synthesized via a sonochemical method which is straightforward, low-cost and operable under ambient conditions. The open spaces formed by carbon nanotubes and graphene offering the accommodation of volume change and the access of an easy electrolyte-wetting, and the improved electrical conductivity by the presence of graphene and carbon nanotubes, lead to the superior cycling performance. As a result, the CSGN with SnO2 content of 61.4 wt% exhibits a reversible specific capacity of 842.9 mAh g?1 at the first cycle and retains 793.8 mAh g?1 after 50 cycles at a current density of 125 mA g?1, indicating a high capacity retention rate of 94%. The cycling performance is attributed to the unique structure of CSGN and enhanced electrical conductivity, which may make much sense to the structure designing of other electrode materials for lithium ion batteries.

Effects of carbon-chain length of trifluoroacetate co-solvents for lithium-ion battery electrolytes using at low temperature  

Science Journals Connector (OSTI)

Abstract Trifluoroacetate is suitable as a co-solvent of rechargeable lithium-ion battery electrolyte for low temperature use. In this work, the following four trifluoroacetate solvents have been studied: (1) methyl trifluoroacetate (MTFA), (2) ethyl trifluoroacetate (ETFA), (3) n-butyl trifluoroacetate (NBTFA), (4) n-hexyl trifluoroacetate (NHTFA). Our efforts focus on the effect of carbon-chain length in trifluorinated acetate's molecular structure. These solvents have been incorporated into multi-component carbonate-based electrolytes and evaluated in lithium–graphite cells. FTIR spectrum has been used to analyze the dissociation of LiPF6 in a single co-solvent. The migration abilities of solvated Li+ have been characterized by ionic conductivities and viscosities. It could be concluded that the trifluoroacetate with long carbon-chain has a weak ability to dissociate LiPF6 salt into free ions, and simultaneously decreases mobility of solvated Li+ in the modified electrolyte. The charge–discharge test has shown a larger capacity shrink of lithium de-intercalation at low temperature and higher polarization potential on graphite electrode. As a low-temperature co-solvent, the carbon-chain length of alcohol group in trifluoroacetate structure should be selected as short as possible.

A Li4Ti5O12–SnO2 composite anode material for lithium-ion batteries has been prepared by loading various amounts of nano-SnO2 on Li4Ti5O12 to obtain composite materials with improved electrochemical performance relative to Li4Ti5O12 and SnO2. The composite materials were characterized by XRD, IR and SEM. The results indicated that SnO2 particles have encapsulated on the surface of the Li4Ti5O12 uniformly and tightly. The influence of SnO2 proportion on the electrochemical properties of Li4Ti5O12–SnO2 composite material was investigated and discussed. The results showed that Li4Ti5O12–SnO2 (5%) has the best cycling behavior among all the samples. At a current rate of 0.5 mA cm?2, the material delivered a discharge capacity of 189 mAh g?1 after 42 cycles. Electrochemical results indicated that the Li4Ti5O12–SnO2 composites increased the reversible capacity of Li4Ti5O12 and cycling reliability of the SnO2 anode material. It suggests the existence of synergistic interaction between Li4Ti5O12 and SnO2 and that the capacity of the composite is not a simple weighted sum of the capacities of the individual components.

Fabrication of carbon microcapsules containing silicon nanoparticles-carbon nanotubes nanocomposite by sol-gel method for anode in lithium ion battery  

SciTech Connect (OSTI)

Carbon microcapsules containing silicon nanoparticles (Si NPs)-carbon nanotubes (CNTs) nanocomposite (Si-CNT-C) have been fabricated by a surfactant mediated sol-gel method followed by a carbonization process. Silicon nanoparticles-carbon nanotubes (Si-CNT) nanohybrids were produced by a wet-type beadsmill method. To obtain Si-CNT nanocomposites with spherical morphologies, a silica precursor (tetraethylorthosilicate, TEOS) and polymer (PMMA) mixture was employed as a structure-directing medium. Thus the Si-CNT/Silica-Polymer microspheres were prepared by an acid catalyzed sol-gel method. Then a carbon precursor such as polypyrrole (PPy) was incorporated onto the surfaces of pre-existing Si-CNT/silica-polymer to generate Si-CNT/Silica-Polymer-PPy microspheres. Subsequent thermal treatment of the precursor followed by wet etching of silica produced Si-CNT-C microcapsules. The intermediate silica/polymer must disappear during the carbonization and etching process resulting in the formation of an internal free space. The carbon precursor polymer should transform to carbon shell to encapsulate remaining Si-CNT nanocomposites. Therefore, hollow carbon microcapsules containing Si-CNT nanocomposites could be obtained (Si-CNT-C). The successful fabrication was confirmed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). These final materials were employed for anode performance improvement in lithium ion battery. The cyclic performances of these Si-CNT-C microcapsules were measured with a lithium battery half cell tests. - Graphical Abstract: Carbon microcapsules containing silicon nanoparticles (Si NPs)-carbon nanotubes (CNTs) nanocomposite (Si-CNT-C) have been fabricated by a surfactant mediated sol-gel method.

The reaction solution is non-corrosive and environmental-friendly. Moreover, the proposed technique does not require complicated infrastructures and heat treatment. The SnO{sub 2}/graphene composite consists of about 4 nm sized SnO{sub 2} nanoparticles with cassiterite structure mono-dispersed on the surface of reduced graphene oxide. As anode for lithium-ion batteries, the SnO{sub 2}/graphene composite shows a satisfying cycling stability (535 mAh g{sup ?1} after 50 cycles @100 mA g{sup ?1}), which is significantly prior to the bare 4 nm sized SnO{sub 2} nanocrsytals. The graphene sheets in the hybrid nanostructure could provide a segmentation effect to alleviate the volume expansion of the SnO{sub 2} and restrain the small and active Sn-based particles aggregating into larger and inactive clusters during cycling.

Development of Production-Intent Plug-In Hybrid Vehicle Using Advanced Lithium-Ion Battery Packs with Deployment to a Demonstration Fleet  

SciTech Connect (OSTI)

The primary goal of this project was to speed the development of one of the first commercially available, OEM-produced plug-in hybrid electric vehicles (PHEV). The performance of the PHEV was expected to double the fuel economy of the conventional hybrid version. This vehicle program incorporated a number of advanced technologies, including advanced lithium-ion battery packs and an E85-capable flex-fuel engine. The project developed, fully integrated, and validated plug-in specific systems and controls by using GM’s Global Vehicle Development Process (GVDP) for production vehicles. Engineering Development related activities included the build of mule vehicles and integration vehicles for Phases I & II of the project. Performance data for these vehicles was shared with the U.S. Department of Energy (DOE). The deployment of many of these vehicles was restricted to internal use at GM sites or restricted to assigned GM drivers. Phase III of the project captured the first half or Alpha phase of the Engineering tasks for the development of a new thermal management design for a second generation battery module. The project spanned five years. It included six on-site technical reviews with representatives from the DOE. One unique aspect of the GM/DOE collaborative project was the involvement of the DOE throughout the OEM vehicle development process. The DOE gained an understanding of how an OEM develops vehicle efficiency and FE performance, while balancing many other vehicle performance attributes to provide customers well balanced and fuel efficient vehicles that are exciting to drive. Many vehicle content and performance trade-offs were encountered throughout the vehicle development process to achieve product cost and performance targets for both the OEM and end customer. The project team completed two sets of PHEV development vehicles with fully integrated PHEV systems. Over 50 development vehicles were built and operated for over 180,000 development miles. The team also completed four GM engineering development Buy-Off rides/milestones. The project included numerous engineering vehicle and systems development trips including extreme hot, cold and altitude exposure. The final fuel economy performance demonstrated met the objectives of the PHEV collaborative GM/DOE project. Charge depletion fuel economy of twice that of the non-PHEV model was demonstrated. The project team also designed, developed and tested a high voltage battery module concept that appears to be feasible from a manufacturability, cost and performance standpoint. The project provided important product development and knowledge as well as technological learnings and advancements that include multiple U.S. patent applications.

Novel Cell Design for Combined In Situ Acoustic Emission and X-ray Diffraction of Cycling Lithium Ion Batteries  

SciTech Connect (OSTI)

An in situ acoustic emission (AE) and X-ray diffraction (XRD) cell for use in the study of battery electrode materials has been devised and tested. This cell uses commercially available coin cell hardware retrofitted with a metalized polyethylene terephthalate (PET) disk which acts as both an X-ray window and a current collector. In this manner the use of beryllium and its associated cost and hazard is avoided. An AE sensor may be affixed to the cell face opposite the PET window in order to monitor degradation effects, such as particle fracture, during cell cycling. Silicon particles which were previously studied by the AE technique were tested in this cell as a model material. The performance of these cells compared well with unmodified coin cells while providing information about structural changes in the active material as the cell is repeatedly charged and discharged.

Lithium transition metal fluorophosphates (Li{sub 2}CoPO{sub 4}F and Li{sub 2}NiPO{sub 4}F) as cathode materials for lithium ion battery from atomistic simulation  

SciTech Connect (OSTI)

Lithium transition metal fluorophosphates (Li{sub 2}MPO{sub 4}F, M: Co and Ni) have been investigated from atomistic simulation. In order to predict the characteristics of these materials as cathode materials for lithium ion batteries, structural property, defect chemistry, and Li{sup +} ion transportation property are characterized. The core–shell model with empirical force fields is employed to reproduce the unit-cell parameters of crystal structure, which are in good agreement with the experimental data. In addition, the formation energies of intrinsic defects (Frenkel and antisite) are determined by energetics calculation. From migration energy calculations, it is found that these flurophosphates have a 3D Li{sup +} ion diffusion network forecasting good Li{sup +} ion conducting performances. Accordingly, we expect that this study provides an atomic scale insight as cathode materials for lithium ion batteries. - Graphical abstract: Lithium transition metal fluorophosphates (Li{sub 2}CoPO{sub 4}F and Li{sub 2}NiPO{sub 4}F).

Novel carbonaceous materials used as anodes in lithium ion cells  

SciTech Connect (OSTI)

The objective of this work is to synthesize disordered carbons used as anodes in lithium ion batteries, where the porosity and surface area are controlled. Both parameters are critical since the irreversible capacity obtained in the first cycle seems to be associated with the surface area (an exfoliation mechanism occurs in which the exposed surface area continues to increase).

Exploring the interaction between lithium ion and defective graphene surface using dispersion corrected DFT studies  

SciTech Connect (OSTI)

To analyze the lithium ion interaction with realistic graphene surfaces, we carried out dispersion corrected DFT-D3 studies on graphene with common point defects and chemisorbed oxygen containing functional groups along with defect free graphene surface. Our study reveals that, the interaction between lithium ion (Li+) and graphene is mainly through the delocalized ? electron of pure graphene layer. However, the oxygen containing functional groups pose high adsorption energy for lithium ion due to the Li-O ionic bond formation. Similarly, the point defect groups interact with lithium ion through possible carbon dangling bonds and/or cation-? type interactions. Overall these defect sites render a preferential site for lithium ions compared with pure graphene layer. Based on these findings, the role of graphene surface defects in lithium battery performance were discussed.

Identifying surface structural changes in layered Li-excess nickel manganese oxides in high voltage lithium ion batteries: A joint experimental and theoretical study  

SciTech Connect (OSTI)

High voltage cathode materials Li-excess layered oxide compounds Li[Ni{sub x}Li{sub 1/3-2x/3}Mn{sub 2/3-x/3}]O{sub 2} (0 < x < 1/2) are investigated in a joint study combining both computational and experimental methods. The bulk and surface structures of pristine and cycled samples of Li[Ni{sub 1/5}Li{sub 1/5}Mn{sub 3/5}]O{sub 2} are characterized by synchrotron X-Ray diffraction together with aberration corrected Scanning Transmission Electron Microscopy (a-S/TEM). Electron Energy Loss Spectroscopy (EELS) is carried out to investigate the surface changes of the samples before/after electrochemical cycling. Combining first principles computational investigation with our experimental observations, a detailed lithium de-intercalation mechanism is proposed for this family of Li-excess layered oxides. The most striking characteristics in these high voltage high energy density cathode materials are (1) formation of tetrahedral lithium ions at voltage less than 4.45 V and (2) the transition metal (TM) ions migration leading to phase transformation on the surface of the materials. We show clear evidence of a new spinel-like solid phase formed on the surface of the electrode materials after high-voltage cycling. It is proposed that such surface phase transformation is one of the factors contributing to the first cycle irreversible capacity and the main reason for the intrinsic poor rate capability of these materials.

Nano-sized Li-Fe composite oxide prepared by a self-catalytic reverse atom transfer radical polymerization approach as an anode material for lithium-ion batteries  

SciTech Connect (OSTI)

A novel Self-catalytic Reverse Atom Transfer Radical Polymerization (RATRP) approach that can provide the radical initiator and the catalyst by the system itself is used to synthesize a nano-sized Li-Fe composite oxide powder in large scale. Its crystalline structure and morphology have been characterized by X-ray diffraction and scanning electron microscopy. The results reveal that the composite is composed of nano-sized LiFeO{sub 2} and Fe{sub 3}O{sub 4}. Its electrochemical properties are evaluated by charge/discharge measurements. The results show that the Li-Fe composite oxide is an excellent anode material for lithium-ion batteries with good cycling performance (1249 mAh g{sup -1} at 100th cycle) and outstanding rate capability (967 mAh g{sup -1} at 5 C). Such a self-catalytic RATRP approach provides a way to synthesize nano-sized iron oxide-based anode materials industrially with preferable electrochemical performance and can also be applied in other polymer-related area.

Redox shuttle is a promising mechanism for intrinsic overcharge protection in lithium-ion cells and batteries. Two lithium borate cluster salts are reported to function as both the main salt for a nonaqueous electrolyte and the redox shuttle for overcharge protection. Lithium borate cluster salts with a tunable redox potential are promising candidates for overcharge protection for most positive electrodes in state-of-the-art lithium-ion cells.

First and ongoing cycle efficiency, total and reversible capacity, cycle life and discharge rate performance were measured to compare these anode materials. We then ranked the graphites using a formula which incorporates these performance measures to estimate the cost of the overall system, relative to the cost of a system using MCMB. This analysis indicates that replacing MCMB with CCP-G8 (Conoco Phillips) would add little to no cost, whereas each of the other graphites would lead to a more costly system. Therefore we chose CCP-G8 as the new baseline graphite for the BATT program.

CRADA Final Report for NFE-08-01826: Development and application of processing and processcontrol for nano-composite materials for lithium ion batteries  

SciTech Connect (OSTI)

Oak Ridge National Laboratory and A123 Systems, Inc. collaborated on this project to develop a better understanding, quality control procedures, and safety testing for A123 System’s nanocomposite separator (NCS) technology which is a cell based patented technology and separator. NCS demonstrated excellent performance. x3450 prismatic cells were shown to survive >8000 cycles (1C/2C rate) at room temperature with greater than 80% capacity retention with only NCS present as an alternative to conventional polyolefin. However, for a successful commercialization, the coating conditions required to provide consistent and reliable product had not been optimized and QC techniques for being able to remove defective material before incorporation into a cell had not been developed. The work outlined in this report addresses these latter two points. First, experiments were conducted to understand temperature profiles during the different drying stages of the NCS coating when applied to both anode and cathode. One of the more interesting discoveries of this study was the observation of the large temperature decrease experienced by the wet coating between the end of the infrared (IR) drying stage and the beginning of the exposure to the convection drying oven. This is not a desirable situation as the temperature gradient could have a deleterious effect on coating quality. Based on this and other experimental data a radiative transfer model was developed for IR heating that also included a mass transfer module for drying. This will prove invaluable for battery coating optimization especially where IR drying is being employed. A stress model was also developed that predicts that under certain drying conditions tensile stresses are formed in the coating which could lead to cracking that is sometimes observed after drying is complete. Prediction of under what conditions these stresses form is vital to improving coating quality. In addition to understanding the drying process other parameters such as slurry quality and equipment optimization were examined. Removal of particles and gels by filtering, control of viscosity by %solids and mixing adjustments, removal of trapped gas in the slurry and modification of coater speed and slot die gap were all found to be important for producing uniform and flaw-free coatings. Second, an in-line Hi-Pot testing method has been developed specifically for NCS that will enable detection of coating flaws that could lead to soft or hard electrical shorts within the cell. In this way flawed material can be rejected before incorporation into the cell thus greatly reducing the amount of scrap that is generated. Improved battery safety is an extremely important benefit of NCS. Evaluation of battery safety is usually accomplished by conducting a variety of tests including nail penetration, hot box, over charge, etc. For these tests entire batteries must be built but the resultant temperature and voltage responses reveal little about the breakdown mechanism. In this report is described a pinch test which is used to evaluate NCS quality at various stages including coated anode and cathode as well as assembled cell. Coupled with post-microscopic examination of the damaged ‘pinch point’ test data can assist in the coating optimization from an improved end-use standpoint. As a result of this work two invention disclosures, one for optimizing drying methodology and the other for an in-line system for flaw detection, have been filed. In addition, 2 papers are being written for submission to peer-reviewed journals.

Although the initial discharge capacity decreases as the fluorine content increasing, the fluorine substituted materials present significant improvement in the cycling performance. Among the synthesized materials, Li[Li1/6Ni1/4Mn7/12]O1.95F0.05 exhibits excellent high temperature (50 °C) cycling performance with a capacity retention of 93.7% after 30 cycles while the bare Li[Li1/6Ni1/4Mn7/12]O2 cathode exhibited only 73.7%.

Under the sponsorship of the US Advanced Battery Consortium (USABC) and the Partnership for a New Generation of Vehicles (PNGV), Saft has developed high-power lithium-ion (Li-Ion) batteries for hybrid electric vehicles (HEVs). These high-power Li-Ion batteries are being evaluated for the US Department of Energy's (DOE) Hybrid Vehicle Propulsion Program. As part of this program, the National Renewable Energy Laboratory (NREL) characterized the thermal performance of the Saft (6-Ah) Li-Ion cells. The characterization included (1) obtaining thermal images of cells under a specified cycle, (2) measuring heat generation from the cells at various temperatures and under various charge/discharge profiles, and (3) determining the cells' capabilities for following a simulated power profile (driving cycle) at various initial states of charge and temperatures.

Electrochemical and Structural Study of the Layered, 'Li-Excess' Lithium-Ion Battery Electrode Material Li[Li[subscript 1/9]Ni[subscript 1/3]Mn[subscript 5/9  

SciTech Connect (OSTI)

The overcapacity mechanism and high voltage process of the Li-excess electrode material Li[Li{sub 1/9}Ni{sub 1/3}Mn{sub 5/9}]O{sub 2} are studied by solid-state NMR, X-ray diffraction, X-ray absorption spectroscopy, transmission electron microscopy, combined with galvanostatic and potentiostatic intermittent titration electrochemical measurements. The cycling performance is improved noticeably when the material is cycled between potential windows of 5.3-2.5 V compared to 4.6-2.5 V. Diffraction data show that structural changes occur at high voltages, the solid-state NMR data of the same samples indicating that the high voltage processes above 4.4 V are associated with Li removal from the structure, in addition to electrolyte decomposition. The NMR spectra of the discharged samples show that cation rearrangements in the transition metal layers have occurred. The XAS spectra confirm that the Mn oxidation state remains unchanged at 4+, whereas Ni{sup 2+} is oxidized to Ni{sup 4+} on charging to 4.4 V, returning to Ni{sup 2+} on discharge, independent of the final charge voltage. A significant change of the shape of the Ni edge is observed in the 4.6-5.3 V potential range on charge, which is ascribed to a change in the Ni local environment. No O{sub 2} evolution was detected based on ex situ analysis of the gases evolved in the batteries, the TEM data showing that thick passivating films form on the electrodes. The results suggest that at least some of the oxygen loss from these lithium-excess materials occurs via a mechanism involving electrolyte decomposition.

Uniform hierarchical SnS microspheres: Solvothermal synthesis and lithium ion storage performance  

SciTech Connect (OSTI)

Graphical abstract: - Highlights: • Uniform hierarchical SnS microspheres via solvothermal reaction. • The formation process was investigated in detail. • The obtained hierarchical SnS microspheres exhibit superior capacity (1650 mAh g{sup ?1}) when used as lithium battery for the hierarchical microsphere structure. - Abstract: Hierarchical SnS microspheres have been successfully synthesized by a mild solvothermal process using poly(vinylpyrrolidone) as surfactant in this work. The morphology and composition of the microspheres were investigated by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The influence of reaction parameters, such as sulfur sources, reaction temperature and the concentration of PVP, on the final morphology of the products are investigated. On the basis of time-dependent experiments, the growth mechanism has also been proposed. The specific surface area of the 3D hierarchitectured SnS microspheres were investigated by using nitrogen adsorption and desorption isotherms. Lithium ion storage performances of the synthesized materials as anodes for Lithium-ion battery were investigated in detail and it exhibits excellent electrochemical properties.

Simulation of Electrolyte Composition Effects on High Energy Lithium-Ion Cells  

SciTech Connect (OSTI)

An important feature of the DUALFOIL model for simulation of lithium-ion cells [1,2] is rigorous accounting for non-ideal electrolyte properties. Unfortunately, data are available on only a few electrolytes [3,4]. However, K. Gering has developed a model for estimation of electrolyte properties [5] and recently generated complete property sets (density, conductivity, activity coefficient, diffusivity, transport number) as a function of temperature and salt concentration. Here we use these properties in an enhanced version of the DUALFOIL model called DISTNP, available in Battery Design Studio [6], to examine the effect of different electrolytes on cell performance. Specifically, the behavior of a high energy LiCoO2/graphite 18650-size cell is simulated. The ability of Battery Design Studio to si

Influence of heat-treatment on lithium ion anode properties of mesoporous carbons with nanosheet-like walls  

SciTech Connect (OSTI)

Highlights: ? Mesoporous carbons possess unique nanosheet-like pore walls which can be changed by heat treatment. ? Lithium ion anode properties of mesoporous carbons could be influenced by the nanosheet-like walls. ? Mesoporous carbons with nanosheet-like walls exhibit enhanced electrochemical properties LIBs. -- Abstract: Mesoporous carbons (MCs) with nanosheet-like walls have been prepared as electrodes for lithium-ion batteries by a simple one-step infiltrating method under the action of capillary flow. The influence of heat treatment temperature on the surface topography, pore/phase structure and anode performances of as-prepared materials has been investigated. The results reveal that melted liquid-crystal polycyclic aromatic hydrocarbons could be anchored on liquid/silica interfaces by molecule engineering. After carbonization, the nanosheets are formed as the pore walls of MCs and are perpendicular to the long axis of pores. The anode properties demonstrate that C-1200 displays higher reversible capacitance than those treated in higher temperature. The rate performances of C-1200 and C-1800 are similar and more excellent than that of C-2400. These improved lithium ion anode properties could be attributed to the nanosheet-like walls of MCs which can be influenced by the heat treatment temperature.

Depollution benchmarks for capacitors, batteries and printed wiring boards from waste electrical and electronic equipment (WEEE)  

SciTech Connect (OSTI)

Highlights: • We’ve analysed data on the dismantling of electronic and electrical appliances. • Ten years of mass balance data of more than recycling companies have been considered. • Percentages of dismantled batteries, capacitors and PWB have been studied. • Threshold values and benchmarks for batteries and capacitors have been identified. • No benchmark for the dismantling of printed wiring boards should be set. - Abstract: The article compiles and analyses sample data for toxic components removed from waste electronic and electrical equipment (WEEE) from more than 30 recycling companies in Switzerland over the past ten years. According to European and Swiss legislation, toxic components like batteries, capacitors and printed wiring boards have to be removed from WEEE. The control bodies of the Swiss take back schemes have been monitoring the activities of WEEE recyclers in Switzerland for about 15 years. All recyclers have to provide annual mass balance data for every year of operation. From this data, percentage shares of removed batteries and capacitors are calculated in relation to the amount of each respective WEEE category treated. A rationale is developed, why such an indicator should not be calculated for printed wiring boards. The distributions of these de-pollution indicators are analysed and their suitability for defining lower threshold values and benchmarks for the depollution of WEEE is discussed. Recommendations for benchmarks and threshold values for the removal of capacitors and batteries are given.

SECONDARY BATTERIES – LITHIUM RECHARGEABLE SYSTEMS | Overview  

Science Journals Connector (OSTI)

Rechargeable lithium batteries have conquered the markets for portable consumer electronics and, recently, for electric vehicles. Lithium, the lightest and one of the most reactive of metals, having the greatest electrochemical potential (E°=–3.045 V), provides very high energy and power densities in batteries. 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.

Production of Batteries for Electric and Hybrid Vehicles Production of Batteries for Electric and Hybrid Vehicles battery assessment graph Lithium-ion (Li-ion) batteries are currently being implemented in hybrid electric (HEV), plug-in hybrid electric (PHEV), and electric (EV) vehicles. While nickel metal-hydride will continue to be the battery chemistry of choice for some HEV models, Li-ion will be the dominate battery chemistry of the remaining market share for the near-future. Large government incentives are currently necessary for customer acceptance of the vehicles such as the Chevrolet Volt and Nissan Leaf. Understanding the parameters that control the cost of Li-ion will help researchers and policy makers understand the potential of Li-ion batteries to meet battery energy density and cost goals, thus enabling widespread adoption without incentives.

Abstract Lithium, the lightest and one of the most reactive of metals, having the greatest electrochemical potential (E0 = ?3.045 V), provides very high energy and power densities in batteries. Rechargeable lithium-ion batteries (containing an intercalation negative electrode) have conquered the markets for portable consumer electronics and, recently, for electric vehicles. The electrolyte is usually based on a lithium salt in organic solution. Thin-film batteries use solid oxide or polymer electrolytes. As lithium metal reacts violently with water and can thus cause ignition, modern lithium-ion batteries use carbon negative electrodes and lithium metal oxide positive electrodes. Rechargeable lithium-ion batteries should not be confused with nonrechargeable lithium primary batteries (containing metallic lithium). This chapter covers all aspects of lithium battery chemistry that are pertinent to electrochemical energy storage for renewable sources and grid balancing.

Eeffect of electrolyte composition on initial cycling and impedance characteristics of lithium-ion-cells.  

SciTech Connect (OSTI)

Hybrid-electric vehicles require lithium-battery electrolytes that form stable, low impedance passivation layers to protect the electrodes, while allowing rapid lithium-ion transport under high current charge/discharge pulses. In this article, we describe data acquired on cells containing LiNi{sub 0.8}Co{sub 0.15}Al{sub 0.05}O{sub 2}-based positive electrodes, graphite-based negative electrodes, and electrolytes with lithium hexafluorophosphate (LiPF{sub 6}), lithium tetrafluoroborate (LiBF{sub 4}), lithium bis(oxalato)borate (LiBOB) and lithium difluoro(oxalato) borate (LiF{sub 2}OB) salts. The impedance data were collected in cells containing a Li-Sn reference electrode to determine effect of electrolyte composition and testing temperature on individual electrode impedance. The full cell impedance data showed the following trend: LiBOB > LiBF{sub 4} > LiF{sub 2}OB > LiPF{sub 6}. The negative electrode impedance showed a trend similar to that of the full cell; this electrode was the main contributor to impedance in the LiBOB and LiBF{sub 4} cells. The positive electrode impedance values for the LiBF{sub 4}, LiF{sub 2}OB, and LiPF{sub 6} cells were comparable; the values were somewhat higher for the LiBOB cell. Cycling and impedance data were also obtained for cells containing additions of LiBF{sub 4}, LiBOB, LiF{sub 2}OB, and vinylene carbonate (VC) to the EC:EMC (3:7 by wt.) + 1.2 M LiPF{sub 6} electrolyte. Our data indicate that the composition and morphology of the graphite SEI formed during the first lithiation cycle is an important determinant of the negative electrode impedance, and hence full cell impedance.

Models for Battery Reliability and Lifetime

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.

Si6H12/Polymer Inks for Electrospinning a-Si Nanowire Lithium Ion Battery Anodes  

SciTech Connect (OSTI)

Amorphous silicon nanowires 'a-SiNWs' have been prepared by electrospinning a liquid silane-based precursor. Cyclohexasilane 'Si6H12' was admixed with poly-methyl methacrylate (PMMA) in toluene giving an ink that was electrospun into the Si6H12/PPMA wires with diameters of 50-2000 nm. Raman spectroscopy revealed that thermal treatment at 350 C transforms this deposit into a-SiNWs. These materials were coated with a thin carbon layer and then tested as half-cells where a reasonable plateau in electrochemical cycling was observed after an initial capacity fade. Additionally, porous a-SiNWs were realized when the thermally decomposable binder polypropylene carbonate/polycyclohexene carbonate was used as the polymer carrier.

Hierarchical functional layers on high-capacity lithium-excess cathodes for superior lithium ion batteries  

Science Journals Connector (OSTI)

Abstract Li-excess layered Li[Li0.2Mn0.54Ni0.13Co0.13]O2 (LMNCO) nanoparticles are facilely synthesized using a surfactant-assisted dispersion method. Ultrathin and conformal oxide coatings are deposited on the surface of individual LMNCO nanoparticle via atomic layer deposition (ALD). The effect of oxide ALD coatings on improving electrochemical performance of LMNCO electrodes is evaluated and optimized via tuning the coating thickness and composition. In addition, we synthesize a novel core–shell structure cathode consisting of Li-excess LMNCO as core and Li-stoichiometric material as shell, and its electrochemical property is optimized by tailoring weight content and composition of shell materials. Finally, electrochemical performance of Li-excess cathode material can be maximized by surface modification with hierarch functional layers composed of 10 wt.% LiCoO2 shell (?10 nm thick) and 6ZrO2 ALD layers (?1 nm thick), which delivers very high initial discharge capacities of 296.4, 259.8, 156.6 and 104.2 mAh g?1 at 0.1C, 1C, 5C and 10C, and can retain 184.0 mAh g?1 at 1C after 100 electrochemical cycles. Such remarkably improved cycleabilitiy and rate capability of nanoarchitected Li-excess layered cathode material can be attributed to the synergic effect from hierarchical functional coatings to reduce electrochemical polarization, structural degradation and side reactions during electrochemical cycling.

Olivine electrode engineering impact on the electrochemical performance of lithium-ion batteries.  

SciTech Connect (OSTI)

High energy and power density lithium iron phosphate was studied for hybrid electric vehicle applications. This work addresses the effects of porosity in a composite electrode using a four-point probe resistivity analyzer, galvanostatic cycling, and electrochemical impedance spectroscopy (EIS). The four-point probe result indicates that the porosity of composite electrode affects the electronic conductivity significantly. This effect is also observed from the cell's pulse current discharge performance. Compared to the direct current (dc) methods used, the EIS data are more sensitive to electrode porosity, especially for electrodes with low porosity values.

Facile synthesis of mesoporous lithium titanate spheres for high rate lithium-ion batteries  

Science Journals Connector (OSTI)

Lithium titanate is synthesized from titanium isopropoxide and lithium acetate solution under hydrothermal environment and calcinations. Introducing acidized carbon black during synthesis can produce mesoporous Li4Ti5O12. The crystalline structure and morphological observation of the as-synthesized mesoporous Li4Ti5O12 are characterized by X-ray diffraction (XRD) and scanning electron microscopy, respectively. The mesoporous structure can be directly observed through BEI images of the cross-section sample. Besides, N2 adsorption/desorption isotherm also displays a hysteresis loop, implying the beneficial evidence of mesoporous structure. The pore size distribution of mesoporous lithium titanate evaluated by BJH model is narrow, and the average size of voids is around 4 nm. It is demonstrated that the electrochemical performance is significantly improved by the mesoporous structure. The mesoporous lithium titanate exhibits a stable capacity of 140 mAhg?1 at 0.5 C. Besides, the reversible capacity at 30 C remains over half of that at 0.5 C. The superior C-rate performance is associated with the mesoporous structure, facilitating lithium transportation ability during cycling.

Electrochemical modeling of lithium-ion positive electrodes during hybrid pulse power characterization tests.  

SciTech Connect (OSTI)

An electrochemical model was developed to examine hybrid pulsed power characterization (HPPC) tests on the positive electrode of lithium-ion cells. By utilizing the same fundamental equations as in previous electrochemical impedance spectroscopy studies, this investigation serves as an extension of the earlier work and a comparison of the two techniques. The electrochemical model was used to examine performance characteristics and limitations for the positive electrode during HPPC tests. Parametric studies using the electrochemical model and focusing on the positive electrode thickness were employed to examine methods of slowing electrode aging and improving performance.

Investigating the low-temperature impedance increase of lithium-ion cells.  

SciTech Connect (OSTI)

Low-temperature performance loss is a significant barrier to commercialization of lithium-ion cells in hybrid electric vehicles. Increased impedance, especially at temperatures below 0 C, reduces the cell pulse power performance required for cold engine starts, quick acceleration, or regenerative braking. Here we detail electrochemical impedance spectroscopy data on binder- and carbon-free layered-oxide and spinel-oxide electrodes, obtained over the +30 to ?30 C temperature range, in coin cells containing a lithium-preloaded Li{sub 4/3}Ti{sub 5/3}O{sub 4} composite (LTOc) counter electrode and a LiPF{sub 6}-bearing ethylene carbonate/ethyl methyl carbonate electrolyte. For all electrodes studied, the impedance increased with decreasing cell temperature; the increases observed in the midfrequency arc dwarfed the increases in ohmic resistance and diffusional impedance. Our data suggest that the movement of lithium ions across the electrochemical interface on the active material may have been increasingly hindered at lower temperatures, especially below 0 C. Low-temperature performance may be improved by modifying the electrolyte-active material interface (for example, through electrolyte composition changes). Increasing surface area of active particles (for example, through nanoparticle use) can lower the initial electrode impedance and lead to lower cell impedances at -30 C.

Synthesis of lithium intercalation materials for rechargeable battery  

Science Journals Connector (OSTI)

Lithium-based oxides (LiMOx, where M=Ni, Co, Mn) are attractive for electrode materials, because they are capable of reversibly intercalating lithium ions for rechargeable battery without altering the main unit. We developed a novel solution-based route for the synthesis of these lithium intercalation oxides, using acetates or oxides as precursors for lithium, manganese, nickel, and cobalt, respectively with proper organic solvents. The evolution of crystal structure of these materials was analyzed by X-ray diffraction. Further analysis of LiMn2O4 samples were carried out using impedance spectroscopy and Raman spectroscopy. These studies indicate that this synthetic route, without using expensive alkoxides of sol–gel process, produces high-quality lithium-based oxides useful for cathode in lithium-ion rechargeable battery.

Emission of Negative Electricity from Nickel when Bombarded by Positive Lithium Ions  

Science Journals Connector (OSTI)

A nickel target was bombarded with positive lithium ions and observations were made of the number of negative charges emitted per positive ion striking the target. The energies of the bombarding ions were within the ranges 1000 to 2000 electron-volts and 5000 to 20,000 electron-volts, approximately. Observations were made with the target at room temperature and at a yellowish-red heat. There is a marked difference between the curves found for the two cases. For the cold target the curve has a maximum between 10,000 and 11,000 volts, while the number of negative charges emitted per positive ion from the hot target increases from 0.13 at 1000 volts to 2.35 at 20,000 volts, no maximum having been found.

Microwave-assisted hydrothermal synthesis of porous SnO{sub 2} nanotubes and their lithium ion storage properties  

SciTech Connect (OSTI)

Porous SnO{sub 2} nanotubes have been synthesized by a rapid microwave-assisted hydrothermal process followed by annealing in air. The detailed morphological and structural studies indicate that the SnO{sub 2} tubes typically have diameters from 200 to 400 nm, lengths from 0.5 to 1.5 {mu}m and wall thicknesses from 50 to 100 nm. The SnO{sub 2} nanotubes are self-assembled by interconnected nanocrystals with sizes {approx}8 nm resulting in a specific surface area of {approx}54 m{sup 2} g{sup -1}. The pristine SnO{sub 2} nanotubes are used to fabricate lithium half cells to evaluate their lithium ion storage properties. The porous SnO{sub 2} nanotubes are characteristic with high lithium ion storage capacity, that is found to be 1258, 951, 757, 603, 458, and 288 mAh g{sup -1}, at 0.1, 0.2, 0.5, 1, 2, and 4C, respectively. The enhanced electrochemical properties of the SnO{sub 2} nanotubes can be ascribed to their unique geometry and porous structures. - Graphical abstract: Porous SnO{sub 2} nanotubes are synthesized by a fast microwave-assisted hydrothermal process and exhibit high lithium ion storage properties due to their unique geometry and porous characteristics.

Characterization of high-power lithium-ion cells-performance and diagnostic analysis  

SciTech Connect (OSTI)

Lithium-ion cells, with graphite anodes and LiNi0.8Co0.15Al0.05O2 cathodes, were cycled for up to 1000 cycles over different ranges of SOC and temperatures. The decline in cell performance increases with the span of SOC and temperature during cycling. Capacity fade was caused by a combination of the loss of cycleable Li and degradation of the cathode. The room temperature anodes showed SEI compositions and degrees of graphite disorder that correlated with the extent of the Li consumption, which was linear in cell test time. TEM of the cathodes showed evidence of crystalline defects, though no major new phases were identified, consistent with XRD. No evidence of polymeric deposits on the cathode particles (FTIR) was detected although both Raman and TEM showed evidence of P-containing deposits from electrolyte salt degradation. Raman microscopy showed differences in relative carbon contents of the cycled cathodes, which is blamed for part of the cathode degradation.

Design and simulation of lithium rechargeable batteries  

SciTech Connect (OSTI)

Lithium -based rechargeable batteries that utilize insertion electrodes are being considered for electric-vehicle applications because of their high energy density and inherent reversibility. General mathematical models are developed that apply to a wide range of lithium-based systems, including the recently commercialized lithium-ion cell. The modeling approach is macroscopic, using porous electrode theory to treat the composite insertion electrodes and concentrated solution theory to describe the transport processes in the solution phase. The insertion process itself is treated with a charge-transfer process at the surface obeying Butler-Volmer kinetics, followed by diffusion of the lithium ion into the host structure. These models are used to explore the phenomena that occur inside of lithium cells under conditions of discharge, charge, and during periods of relaxation. Also, in order to understand the phenomena that limit the high-rate discharge of these systems, we focus on the modeling of a particular system with well-characterized material properties and system parameters. The system chosen is a lithium-ion cell produced by Bellcore in Red Bank, NJ, consisting of a lithium-carbon negative electrode, a plasticized polymer electrolyte, and a lithium-manganese-oxide spinel positive electrode. This battery is being marketed for consumer electronic applications. The system is characterized experimentally in terms of its transport and thermodynamic properties, followed by detailed comparisons of simulation results with experimental discharge curves. Next, the optimization of this system for particular applications is explored based on Ragone plots of the specific energy versus average specific power provided by various designs.

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.
