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

SciTech Connect

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 70C). 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.

Calendar and PHEV Cycle Life Aging of High-Energy, Lithium-Ion Cells Containing Blended Spinel and Layered-Oxide Cathodes  

DOE Green Energy (OSTI)

One hundred seven commercially available, off-the-shelf, 1.2-Ah cells were tested for calendar life and CS cycle- and CD cycle-life using the new USABC PHEV Battery Test Manual. Here, the effects of temperature on calendar life, on CS cycle life, and on CD cycle life; the effects of SOC on calendar life and on CS cycle life; and the effects of rest time on CD cycle life were investigated. The results indicated that the test procedures caused performance decline in the cells in an expected manner, calendar < CS cycling < CD cycling. In some cases, the kinetic law changed with test type, from linear-with-time to about t2. Additionally, temperature was found to stress the cells more than SOC, causing increased changes in performance with increasing temperature.

Calendars Calendars Nature Bulletin No. 447-A March 4, 1972 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation CALENDARS This is a Leap Year with 366 days instead of the usual 365, and 29 days in February. Julius Caesar was responsible for that. The Roman calendar was patterned after those of the ancient Greeks and Egyptians which, in turn, had been modeled on that of the early Sumerians in Babylonia. The Sumerians had 12 lunar months in a year but every so often, to make up for the difference between that year and the year of the natural seasons, their astronomer-priests inserted an extra month. The Roman year was too short. It had had only 365 days for so many centuries that their calendar was badly out of step with the seasons and something had to be done about it. The summer months were coming in spring. Caesar's astronomers told him the reason: instead of being exactly 365 days long, a year was 365 and one-quarter days in length. Julius then solved the problem -- so he thought -- by establishing a leap year of 366 days every fourth year. He put the extra day in February because that was the last month on the old Roman calendar. Their new year started on the first day of March.

Battery Technology Life Verification Testing and Analysis  

DOE Green Energy (OSTI)

A critical component to the successful commercialization of batteries for automotive applications is accurate life prediction. The Technology Life Verification Test (TLVT) Manual was developed to project battery life with a high level of statistical confidence within only one or two years of accelerated aging. The validation effort that is presently underway has led to several improvements to the original methodology. For example, a newly developed reference performance test revealed a voltage path dependence effect on resistance for lithium-ion cells. The resistance growth seems to depend on how a target condition is reached (i.e., by a charge or a discharge). Second, the methodology for assessing the level of measurement uncertainty was improved using a propagation of errors in the fundamental measurements to the derived response (e.g., resistance). This new approach provides a more realistic assessment of measurement uncertainty. Third, the methodology for allocating batteries to the test matrix has been improved. The new methodology was developed to assign batteries to the matrix such that the average of each test group would be representative of the overall population. These changes to the TLVT methodology will help to more accurately predict a battery technologys life capability with a high degree of confidence.

Battery Life Prediction Method for Hybrid Power Applications: Preprint  

Science Conference Proceedings (OSTI)

Batteries in hybrid power applications that include intermittent generators, such as wind turbines, experience a very irregular pattern of charge and discharge cycles. Because battery life is dependent on both depth and rate of discharge (and other factors such as temperature, charging strategy, etc.), estimating battery life and optimally sizing batteries for hybrid systems is difficult. Typically, manufacturers give battery life data, if at all, as cycles to failure versus depth of discharge, where all discharge cycles are assumed to be under conditions of constant temperature, current, and depth of discharge. Use of such information directly can lead to gross errors in battery lifetime estimation under actual operating conditions, which may result in either a higher system cost than necessary or an undersized battery bank prone to early failure. Even so, most current battery life estimation algorithms consider only the effect of depth of discharge on cycle life. This paper will discuss a new battery life prediction method, developed to investigate the effects of two primary determinants of battery life in hybrid power applications, varying depths of discharge and varying rates of discharge. A significant feature of the model is that it bases its analysis on battery performance and cycle life data provided by the manufacturer, supplemented by a limited amount of empirical test data, eliminating the need for an electrochemical model of the battery. It performs the analysis for a user-prescribed discharge profile consisting of a series of discharge events of specified average current and duration. Sample analyses are presented to show how the method can be used to select the most economical battery type and size for a given hybrid power system application.

?Just-in-Time? Battery Charge Depletion Control for PHEVs and E-REVs for Maximum Battery Life  

SciTech Connect

Conventional methods of vehicle operation for Plug-in Hybrid Vehicles first discharge the battery to a minimum State of Charge (SOC) before switching to charge sustaining operation. This is very demanding on the battery, maximizing the number of trips ending with a depleted battery and maximizing the distance driven on a depleted battery over the vehicle s life. Several methods have been proposed to reduce the number of trips ending with a deeply discharged battery and also eliminate the need for extended driving on a depleted battery. An optimum SOC can be maintained for long battery life before discharging the battery so that the vehicle reaches an electric plug-in destination just as the battery reaches the minimum operating SOC. These Just-in-Time methods provide maximum effective battery life while getting virtually the same electricity from the grid.

A long-life deep cycle, tubular lead-acid battery  

SciTech Connect

The lead-acid battery is used in a variety of applications to provide primary and stand-by power. Because the battery significantly impacts the system cost, it behooves the designer to select a battery having the minimum life-cycle cost. Tubular batteries generally enjoy a longer life than equivalent flat plate batteries. This is because the frequency and severity of the most prevalent modes of failure are much reduced. Since the specific capacity of a tubular battery is comparable to that of a flat plate battery, the use of a tubular battery can result in a reduced system life-cycle cost.

Comparison of Battery Life Across Real-World Automotive Drive-Cycles (Presentation)  

DOE Green Energy (OSTI)

Laboratories run around-the-clock aging tests to try to understand as quickly as possible how long new Li-ion battery designs will last under certain duty cycles. These tests may include factors such as duty cycles, climate, battery power profiles, and battery stress statistics. Such tests are generally accelerated and do not consider possible dwell time at high temperatures and states-of-charge. Battery life-predictive models provide guidance as to how long Li-ion batteries may last under real-world electric-drive vehicle applications. Worst-case aging scenarios are extracted from hundreds of real-world duty cycles developed from vehicle travel surveys. Vehicles examined included PHEV10 and PHEV40 EDVs under fixed (28 degrees C), limited cooling (forced ambient temperature), and aggressive cooling (20 degrees C chilled liquid) scenarios using either nightly charging or opportunity charging. The results show that battery life expectancy is 7.8 - 13.2 years for the PHEV10 using a nightly charge in Phoenix, AZ (hot climate), and that the 'aggressive' cooling scenario can extend battery life by 1-3 years, while the 'limited' cooling scenario shortens battery life by 1-2 years. Frequent (opportunity) charging can reduce battery life by 1 year for the PHEV10, while frequent charging can extend battery life by one-half year.

Life-cycle energy analyses of electric vehicle storage batteries. Final report  

DOE Green Energy (OSTI)

The results of several life-cycle energy analyses of prospective electric vehicle batteries are presented. The batteries analyzed were: Nickel-zinc; Lead-acid; Nickel-iron; Zinc-chlorine; Sodium-sulfur (glass electrolyte); Sodium-sulfur (ceramic electrolyte); Lithium-metal sulfide; and Aluminum-air. A life-cycle energy analysis consists of evaluating the energy use of all phases of the battery's life, including the energy to build it, operate it, and any credits that may result from recycling of the materials in it. The analysis is based on the determination of three major energy components in the battery life cycle: Investment energy, i.e., The energy used to produce raw materials and to manufacture the battery; operational energy i.e., The energy consumed by the battery during its operational life. In the case of an electric vehicle battery, this energy is the energy required (as delivered to the vehicle's charging circuit) to power the vehicle for 100,000 miles; and recycling credit, i.e., The energy that could be saved from the recycling of battery materials into new raw materials. The value of the life-cycle analysis approach is that it includes the various penalties and credits associated with battery production and recycling, which enables a more accurate determination of the system's ability to reduce the consumption of scarce fuels. The analysis of the life-cycle energy requirements consists of identifying the materials from which each battery is made, evaluating the energy needed to produce these materials, evaluating the operational energy requirements, and evaluating the amount of materials that could be recycled and the energy that would be saved through recycling. Detailed descriptions of battery component materials, the energy requirements for battery production, and credits for recycling, and the operational energy for an electric vehicle, and the procedures used to determine it are discussed.

A review of battery life-cycle analysis : state of knowledge and critical needs.  

DOE Green Energy (OSTI)

A literature review and evaluation has been conducted on cradle-to-gate life-cycle inventory studies of lead-acid, nickel-cadmium, nickel-metal hydride, sodium-sulfur, and lithium-ion battery technologies. Data were sought that represent the production of battery constituent materials and battery manufacture and assembly. Life-cycle production data for many battery materials are available and usable, though some need updating. For the remaining battery materials, lifecycle data either are nonexistent or, in some cases, in need of updating. Although battery manufacturing processes have occasionally been well described, detailed quantitative information on energy and material flows is missing. For all but the lithium-ion batteries, enough constituent material production energy data are available to approximate material production energies for the batteries, though improved input data for some materials are needed. Due to the potential benefit of battery recycling and a scarcity of associated data, there is a critical need for life-cycle data on battery material recycling. Either on a per kilogram or per watt-hour capacity basis, lead-acid batteries have the lowest production energy, carbon dioxide emissions, and criteria pollutant emissions. Some process-related emissions are also reviewed in this report.

PNGV Battery Performance Testing and Analyses  

SciTech Connect

In support of the Partnership for a New Generation of Vehicles (PNGV), the Idaho National Engineering and Environmental Laboratory (INEEL) has developed novel testing procedures and analytical methodologies to assess the performance of batteries for use in hybrid electric vehicles (HEVs). Tests have been designed for both Power Assist and Dual Mode applications. They include both characterization and cycle life and/or calendar life. At periodic intervals during life testing, a series of Reference Performance Tests are executed to determine changes in the baseline performance of the batteries. Analytical procedures include a battery scaling methodology, the calculation of pulse resistance, pulse power, available energy, and differential capacity, and the modeling of calendar- and cycle-life data. PNGV goals, test procedures, analytical methodologies, and representative results are presented.

Nickel-zinc batteries for RPV applications. Interim technical report 15 Nov 78-15 Dec 79  

SciTech Connect

Interim results are presented for a program dealing with the placement of nickel-zinc batteries in specific military applications, namely the BQM-34A and the PQM-102 Remotely Piloted Vehicles. The nickel-zinc system was chosen for these applications because RPV's demand a high quality secondary battery that offers a compromise between long life (calendar and cycle) and low weight and volume. Program tasks include continued development of the nickel zinc system, calendar and cycle life testing of the two candidate batteries, qualification testing, and flight testing in operational RPV's. Test results of developmental cells and batteries include cycle life testing of various separator materials, high rate/low temperature discharges with various types of nickel electrodes, zinc electrode substrate, and charging methods. Calendar and cycle life testing is underway which will demonstrate the ability of the nickel-zinc system to be routinely cycled over an extended period of time.

Performance and life evaluation of nickel/iron battery technology for dual shaft electric propulsion vehicle  

SciTech Connect

As part of a cost-shared contract between the US Department of Energy (Office of Transportation Systems) and Eaton Corp. to develop an advanced dual shaft electric propulsion (DSEP) vehicle, several nickel/iron (Ni/Fe) batteries were designed and procured from Eagle-Picher Industries (EPI) for evaluation and vehicle use. In March 1986, two individual 5-cell Ni/Fe modules and a 140-cell (28-module) battery pack were delivered to Argonne for evaluation. Performance characterization tests were conducted on the two modules and life testing performed on the battery pack. Module performance testing was completed in early 1987 after about 215 cycles of operation. Each module still retained {approximately}90% of its initial 180-Ah capacity at the end of testing ({approximately}163 Ah/970 Wh). Life evaluation of the 168-V, 28-kWh battery pack was conducted with driving profile discharges. A 1377-s power profile that represented the battery load in a DSEP vehicle undergoing a Federal Urban Driving Schedule (FUDS) was used. Testing was temporarily suspended in October 1987 after the battery pack had accumulated 502 cycles (209 cycles in 1986). After a three-month trickle charge ({approximately}3 A), testing was resumed (January 1988) with driving profile discharges. In March 1988, battery performance was being limited by three modules. After 545 cycles, the three modules were removed from the pack. Battery performance, however, continued to decline and another four modules were removed in September 1988 (645 cycles). Several remaining modules started to exhibit a high self-discharge loss and a capacity of only 119 Ah (15.1 kWh) could be achieved. The life evaluation was halted in October 1988 after 661 cycles had been accumulated. This report outlines the test activities and presents the performance results of the individual modules and the battery pack involved in this technology evaluation. 18 figs., 4 tabs.

Researchers at the National Renewable Energy Laboratory (NREL) are providing new insights into the relationships between the climate-control systems of plug-in electric vehicles and the distances these vehicles can travel on a single charge. In particular, NREL research has determined that 'preconditioning' a vehicle-achieving a comfortable cabin temperature and preheating or precooling the battery while the vehicle is still plugged in-can extend its driving range and improve battery life over the long term.

Materials Processing for Lithium-Ion Batteries  

SciTech Connect

Extensive efforts have been undertaken to develop and optimize new materials for lithium-ion batteries to address power and energy demands of mobile electronics and electric vehicles. However, the introduction of large-format lithium-ion batteries is hampered by high cost, safety concerns, and deficiencies in energy density and calendar life. Advanced materials-processing techniques can contribute solutions to such issues. From that perspective, this work summarizes the materials-processing techniques used to fabricate the cathodes, anodes, and separators used in lithium-ion batteries.

Effect of electrolyte additives in improving the cycle and calendar life of graphite/Li{sub1.1}[Ni{sub1/3}Co{sub1/3}Mn{sub1/3}]{0.9}O{sub 2} Li-ion cells.  

DOE Green Energy (OSTI)

Lithium-rich layered metal oxide Li{sub 1.1}[Ni{sub 1/3}Co{sub 1/3}Mn{sub 1/3}]{sub 0.9}O{sub 2} was investigated as a potential positive electrode material for high-power batteries for hybrid electric vehicle (HEV) applications. In order to evaluate the power and life characteristics of the graphite/Li{sub 1.1}[Ni{sub 1/3}Co{sub 1/3}Mn{sub 1/3}]{sub 0.9}O{sub 2} cell chemistry, hybrid pulse power characterization (HPPC) and accelerated calendar life tests were conducted on several pouch cells containing electrolytes with and without additives. The data show that the cells containing 0.5 wt% lithium bis(oxalate)borate (LiBOB) or vinyl ethyl carbonate (VEC) additives, or the novel lithium difluoro(oxalato)borate (LiDFOB) additive, have much improved cycle and calendar life performance.

Characterization of vacuum-multifoil insulation for long-life thermal batteries  

DOE Green Energy (OSTI)

The use of vacuum multifoil (VMF) container for thermal insulation in long-life thermal batteries was investigated in a proof-of-concept demonstration. An InvenTek-designed VMF container 4.9 inches in diameter by 10 inches long was used with an internally heated aluminum block, to simulate a thermal-battery stack. The block was heated to 525 C or 600 C and allowed to cool while monitoring the temperature of the block and the external case at three locations with time. The data indicate that it should be possible to build an equivalent-sized thermal battery that should last up to six hours, which would meet the requirements for a long-life sonobuoy application.

A Vehicle Systems Approach to Evaluate Plug-in Hybrid Battery Cold Start, Life and Cost Issues  

E-Print Network (OSTI)

The batteries used in plug-in hybrid electric vehicles (PHEVs) need to overcome significant technical challenges in order for PHEVs to become economically viable and have a large market penetration. The internship at Argonne National Laboratory (ANL) involved two experiments which looked at a vehicle systems approach to analyze two such technical challenges: Battery life and low battery power at cold (-7 ?C) temperature. The first experiment, concerning battery life and its impact on gasoline savings due to a PHEV, evaluates different vehicle control strategies over a pre-defined vehicle drive cycle, in order to identify the control strategy which yields the maximum dollar savings (operating cost) over the life of the vehicle, when compared to a charge sustaining hybrid. Battery life degradation over the life of the vehicle, and fuel economy savings on every trip (daily) are taken into account when calculating the net present value of the gasoline dollars saved. The second experiment evaluates the impact of different vehicle control strategies in heating up the PHEV battery (due to internal ohmic losses) for cold ambient conditions. The impact of low battery power (available to the vehicle powertrain) due to low battery and ambient temperatures has been well documented in literature. The trade-off between the benefits of heating up the battery versus heating up the internal combustion engine are evaluated, using different control strategies, and the control strategy, which provided optimum temperature rise of each component, is identified.

Temperature effects on sealed lead acid batteries and charging techniques to prolong cycle life.  

DOE Green Energy (OSTI)

Sealed lead acid cells are used in many projects in Sandia National Laboratories Department 2660 Telemetry and Instrumentation systems. The importance of these cells in battery packs for powering electronics to remotely conduct tests is significant. Since many tests are carried out in flight or launched, temperature is a major factor. It is also important that the battery packs are properly charged so that the test is completed before the pack cannot supply sufficient power. Department 2665 conducted research and studies to determine the effects of temperature on cycle time as well as charging techniques to maximize cycle life and cycle times on sealed lead acid cells. The studies proved that both temperature and charging techniques are very important for battery life to support successful field testing and expensive flight and launched tests. This report demonstrates the effects of temperature on cycle time for SLA cells as well as proper charging techniques to get the most life and cycle time out of SLA cells in battery packs.

Comparison of Plug-In Hybrid Electric Vehicle Battery Life Across Geographies and Drive-Cycles  

DOE Green Energy (OSTI)

In a laboratory environment, it is cost prohibitive to run automotive battery aging experiments across a wide range of possible ambient environment, drive cycle and charging scenarios. Since worst-case scenarios drive the conservative sizing of electric-drive vehicle batteries, it is useful to understand how and why those scenarios arise and what design or control actions might be taken to mitigate them. In an effort to explore this problem, this paper applies a semi-empirical life model of the graphite/nickel-cobalt-aluminum lithium-ion chemistry to investigate impacts of geographic environments under storage and simplified cycling conditions. The model is then applied to analyze complex cycling conditions, using battery charge/discharge profiles generated from simulations of PHEV10 and PHEV40 vehicles across 782 single-day driving cycles taken from Texas travel survey data.

Cycle life testing of lithium-ion batteries for small satellite LEO space missions  

DOE Green Energy (OSTI)

In 1990, Sony corporation announced their intention to manufacture a rechargeable lithium ion battery, based on the intercalation of lithium ions into a carbonaceous anode. The cells were first introduced for portable telephone use in June, 1991. (1) A 3.6V average cell voltage (4.1-2.75V range); (2) Excellent cycle life (1200 @ 100% DOD); (3) Good capacity retention (70% after 6 months); (4) Wide temperature range performance ({minus}20 to +60{degrees}C); (5) Excellent Discharge rate (82% capacity at 30 min. discharge rate); (6) Excellent Charge rate (100% Charge in <3 hrs); and (7) High energy density (264 W*hr/1 and 120 Whr/kg for ``D`` size cell. These specifications show significant promise for application of these batteries in low earth orbit (LEO) small satellites, particularly when compared to existing NiH{sub 2} and NiCd technology. The very high energy density and specific energy will reduce power system volume and weight. The wide temperature range enables simpler thermal design, particularly for new, small, high power satellites. The materials used in the lithium ion batteries are relatively inexpensive and benign, so that we expect costs to come down substantially in the future. The specified cycle life at 100% DOD is also 50% longer than most NiCds, so low DOD (depth of discharge) performance could be substantial. This study was undertaken to: (a) assess the feasibility for using lithium ion cells on small satellite LEO missions and (b) verify the claims of the manufacturer. This was accomplished by performing a detailed autopsy and various depth of discharge and rate tests on the cells. Of special interest was the cycle life performance of these cell at various depths of discharge DOD`s, to get an initial measure of the reduction in capacity fade with cycle conditions. Low DOD`s are used to extend the life of all batteries used in a space application.

Battery Wear from Disparate Duty-Cycles: Opportunities for Electric-Drive Vehicle Battery Health Management; Preprint  

SciTech Connect

Electric-drive vehicles utilizing lithium-ion batteries experience wholly different degradation patterns than do conventional vehicles, depending on geographic ambient conditions and consumer driving and charging patterns. A semi-empirical life-predictive model for the lithium-ion graphite/nickel-cobalt-aluminum chemistry is presented that accounts for physically justified calendar and cycling fade mechanisms. An analysis of battery life for plug-in hybrid electric vehicles considers 782 duty-cycles from travel survey data superimposed with climate data from multiple geographic locations around the United States. Based on predicted wear distributions, opportunities for extending battery life including modification of battery operating limits, thermal and charge control are discussed.

Nickel-zinc batteries for RPV applications. Final technical report 15 Nov 79-15 Aug 81  

SciTech Connect

Final technical results are presented for a program dealing with the placement of nickel-zinc batteries in specific military applications, namely the BQM-34A and the PQM-102 Remotely Piloted Vehicles (RPV's). The nickel-zinc system was selected for these applications because RPV's demand a high quality secondary battery that offers a compromise between long life (calendar and cycle) and low weight and volume.

High energy cathode material for long-life and safe lithium batteries.  

DOE Green Energy (OSTI)

Layered lithium nickel-rich oxides, Li[Ni{sub 1-x}M{sub x}]O{sub 2} (M=metal), have attracted significant interest as the cathode material for rechargeable lithium batteries owing to their high capacity, excellent rate capability and low cost. However, their low thermal-abuse tolerance and poor cycle life, especially at elevated temperature, prohibit their use in practical batteries. Here, we report on a concentration-gradient cathode material for rechargeable lithium batteries based on a layered lithium nickel cobalt manganese oxide. In this material, each particle has a central bulk that is rich in Ni and a Mn-rich outer layer with decreasing Ni concentration and increasing Mn and Co concentrations as the surface is approached. The former provides high capacity, whereas the latter improves the thermal stability. A half cell using our concentration-gradient cathode material achieved a high capacity of 209 mA h g{sup -1} and retained 96% of this capacity after 50 charge-discharge cycles under an aggressive test profile (55 C between 3.0 and 4.4 V). Our concentration-gradient material also showed superior performance in thermal-abuse tests compared with the bulk composition Li[Ni{sub 0.8}Co{sub 0.1}Mn{sub 0.1}]O{sub 2} used as reference. These results suggest that our cathode material could enable production of batteries that meet the demanding performance and safety requirements of plug-in hybrid electric vehicles.

Development of novel strategies for enhancing the cycle life of lithium solid polymer electrolyte batteries. Final report  

SciTech Connect

Lithium/solid polymer electrolyte (Li/SPE) secondary batteries are under intense development as power sources for portable electronic devices as well as electric vehicles. These batteries offer high specific energy, high energy density, very low self-discharge rates, and flexibility in packaging; however, problems have inhibited their introduction into the marketplace. This report summarizes findings to examine processes that occur with Li/SPE secondary batteries upon cyclic charging/discharging. The report includes a detailed analysis of the impedance measured on the Li/SPE/IC and IC/SPE/IC systems. The SPE was a derivative of methoxyethoxyethoxyphosphazene (MEEP) with lithium triflate salt as the electrolyte, while the intercalated cathodes (IC) comprised mixtures of manganese dioxide, carbon powder, and MEEP as a binder. Studies on symmetrical Li/SPE/Li laminates show that cycling results in a significant expansion of the structure over the first few tens of cycles; however, no corresponding increase in the impedance was noted. The cycle life of the intercalation cathode was found to be very sensitive to the method of fabrication. Results indicate that the cycle life is due to the failure of the IC, not to the failure of the lithium/SPE interface. A pattern recognition neural network was developed to predict the cycle life of a battery from the charge/discharge characteristics.

Materials cost evaluation report for high-power Li-ion batteries.  

SciTech Connect

The U.S. Department of Energy (DOE) is the lead federal agency in the partnership between the U.S. automobile industry and the federal government to develop fuel cell electric vehicles (FCEVs) and hybrid electric vehicles (HEVs) as part of the FreedomCAR Partnership. DOE's FreedomCAR and Vehicle Technologies Office sponsors the Advanced Technology Development (ATD) Program--involving 5 of its national laboratories--to assist the industrial developers of high-power lithium-ion batteries to overcome the barriers of cost, calendar life, and abuse tolerance so that this technology can be rendered practical for use in HEV and FCEV applications under the FreedomCAR Partnership. In the area of cost reduction, Argonne National Laboratory (ANL) is working to identify and develop advanced anode, cathode, and electrolyte components that can significantly reduce the cost of the cell chemistry, while simultaneously extending the calendar life and enhancing the inherent safety of this electrochemical system. The material cost savings are quantified and tracked via the use of a cell and battery design model that establishes the quantity of each material needed in the production of batteries that are designed to meet the requirements of a minimum-power-assist HEV battery or a maximum-power-assist HEV battery for the FreedomCAR Partnership. Similar models will be developed for FEV batteries when the requirements for those batteries are finalized. In order to quantify the material costs relative to the FreedomCAR battery cost goals, ANL uses (1) laboratory cell performance data, (2) its battery design model and (3) battery manufacturing process yields to create battery-level material cost models. Using these models and industry-supplied material cost information, ANL assigns battery-level material costs for different cell chemistries. These costs can then be compared with the battery cost goals to determine the probability of meeting the goals with these cell chemistries. As can be seen from the results of this materials cost study, a cell chemistry based on the use of a LiMn{sub 2}O{sub 4} cathode material is lowest-cost and meets our battery-level material cost goal of <$250 for a 25-kW minimum-power-assist HEV battery. A major contributing factor is the high-rate capability of this material, which allows one to design a lower-capacity cell to meet the battery-level power and energy requirements. This reduces the quantities of the other materials needed to produce a 25-kW minimum-power-assist HEV battery. The same is true for the 40-kW maximum-power-assist HEV battery. Additionally, the LiMn{sub 2}O{sub 4} cathode is much more thermally and chemically stable than the LiNi{sub 0.8}Co{sub 0.2}O{sub 2} type cathode, which should enhance inherent safety and extend calendar life (if the LiMn{sub 2}O{sub 4} cathode can be stabilized against dissolution via HF attack). Therefore, we recommend that the FreedomCAR Partnership focus its research and development efforts on developing this type of low-cost high-power lithium-ion cell chemistry. Details supporting this recommendation are provided in the body of this report.

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

DOE Green Energy (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.

Battery-level material cost model facilitates high-power li-ion battery cost reductions.  

SciTech Connect

Under the FreedomCAR Partnership, Argonne National Laboratory (ANL) is working to identify and develop advanced anode, cathode, and electrolyte components that can significantly reduce the cost of the cell chemistry, while simultaneously enhancing the calendar life and inherent safety of high-power Li-Ion batteries. Material cost savings are quantified and tracked via the use of a cell and battery design model that establishes the quantity of each material needed in batteries designed to meet the requirements of hybrid electric vehicles (HEVs). In order to quantify the material costs, relative to the FreedomCAR battery cost goals, ANL uses (1) laboratory cell performance data, (2) its battery design model and (3) battery manufacturing process yields to create battery-level material cost models. Using these models and industry-supplied material cost information, ANL assigns battery-level material costs for different cell chemistries. These costs can then be compared to the battery cost goals to determine the probability of meeting the goals with these cell chemistries. The most recent freedomCAR cost goals for 25-kW and 40-kW power-assist HEV batteries are $500 and $800, respectively, which is $20/kW in both cases. In 2001, ANL developed a high-power cell chemistry that was incorporated into high-power 18650 cells for use in extensive accelerated aging and thermal abuse characterization studies. This cell chemistry serves as a baseline for this material cost study. It incorporates a LiNi0.8Co0.15Al0.05O2 cathode, a synthetic graphite anode, and a LiPF6 in EC:EMC electrolyte. Based on volume production cost estimates for these materials-as well as those for binders/solvents, cathode conductive additives, separator, and current collectors--the total cell winding material cost for a 25-kW power-assist HEV battery is estimated to be $399 (based on a 48- cell battery design, each cell having a capacity of 15.4 Ah). This corresponds to {approx}$16/kW. Our goal is to reduce the cell winding material cost to <$10/kW, in order to allow >$10/kW for the cell and battery manufacturing costs, as well as profit for the industrial manufacturer. The material cost information is obtained directly from the industrial material suppliers, based on supplying the material quantities necessary to support an introductory market of 100,000 HEV batteries/year. Using its battery design model, ANL provides the material suppliers with estimates of the material quantities needed to meet this market, for both 25-kW and 40-kW power-assist HEV batteries. Also, ANL has funded a few volume-production material cost analyses, with industrial material suppliers, to obtain needed cost information. In a related project, ANL evaluates and develops low-cost advanced materials for use in high-power Li-Ion HEV batteries. [This work is the subject of one or more separate papers at this conference.] Cell chemistries are developed from the most promising low-cost materials. The performance characteristics of test cells that employ these cell chemistries are used as input to the cost model. Batteries, employing these cell chemistries, are designed to meet the FreedomCAR power, energy, weight, and volume requirements. The cost model then provides a battery-level material cost and material cost breakdown for each battery design. Two of these advanced cell chemistries show promise for significantly reducing the battery-level material costs (see Table 1), as well as enhancing calendar life and inherent safety. It is projected that these two advanced cell chemistries (A and B) could reduce the battery-level material costs by an estimated 24% and 43%, respectively. An additional cost advantage is realized with advanced chemistry B, due to the high rate capability of the 3-dimensional LiMn{sub 2}O{sub 4} spinel cathode. This means that a greater percentage of the total Ah capacity of the cell is usable and cells with reduced Ah capacity can be used. This allows for a reduction in the quantity of the anode, electrolyte, separator, and current collector materials needed f

Systems approach to rechargeable batteries

When selecting a rechargeable battery for an application, consideration must be given to the total system. Electrical load requirements, mechanical restrictions, environmental conditions, battery life, and charging must be considered to assure satisfactory battery performance. Meeting the electrical requirements involves selecting a battery that will deliver adequate voltage, run time and power. The mechanical aspects are largely a matter of resolving volume and weight. The charger must be capable of returning the battery to full charge in an allotted time. But of greater importance, the charge control method should be chosen carefully to maximize the operational life of the battery. 4 refs.

Battery chargers  

SciTech Connect

A battery charger designed to be installed in a vehicle, and while utilizing a portion of this vehicle's electrical system, can be used to charge another vehicle's battery or batteries. This battery charger has a polarity sensor, and when properly connected to an external battery will automatically switch away from charging the internal battery to charging the external battery or batteries. And, when disconnected from the external battery or batteries will automatically switch back to charging the internal battery, thus making it an automatic vehicle to vehicle battery charger.

NLE Websites -- All DOE Office Websites (Extended Search)

Goals Goals Environmental pollution and the looming energy crisis have been attracting significant concerns worldwide. Much of the criticism has been directed to the consumption of fossil fuels and the greenhouse gases emitted by automobiles, which consume almost 45% of all fossil fuels produced. The huge amount of carbon dioxide emitted by automobiles is also highly blamed for global warming. Recently, there has been a worldwide active effort to develop hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) to effectively reduce the consumption of fossil fuels in the transportation sector. Among the available battery technologies, lithium-ion batteries have the highest capacity density and energy density, and are promising candidates for energy storage devices for HEV and PHEV with improved energy efficiency. However, the key technological barriers that hinder commercial use of lithium-ion batteries for HEV and PHEV are their high cost, not enough calendar and cycle life, limited low temperature performance during cold cranking, and intrinsic abuse tolerance.

PNGV battery test manual  

DOE Green Energy (OSTI)

This manual defines a series of tests to characterize aspects of the performance or life cycle behavior of batteries for hybrid electric vehicle applications. Tests are defined based on the Partnership for New Generation Vehicles (PNGV) program goals, although it is anticipated these tests may be generally useful for testing energy storage devices for hybrid electric vehicles. Separate test regimes are defined for laboratory cells, battery modules or full size cells, and complete battery systems. Some tests are common to all three test regimes, while others are not normally applicable to some regimes. The test regimes are treated separately because their corresponding development goals are somewhat different.

Screening report on cell materials for high-power Li-Ion HEV batteries.  

DOE Green Energy (OSTI)

The Battery Technology Department at Argonne National Laboratory is a major participant in the U.S. Department of Energy's Advanced Technology Development (ATD) program. This multi-national laboratory program is dedicated to improving lithium-ion batteries for high-power HEV and FCEV applications. As part of the FreedomCAR Partnership, this program is addressing the three key barriers for high-power lithium-ion batteries: calendar life, abuse tolerance, and cost. All three of these barriers can be addressed by the choice of materials used in the cell chemistry. To date, the ATD program has developed two high-power cell chemistries, denoted our Gen 1 and Gen 2 cell chemistries. The selection of materials for use in the Gen 2 cell chemistry was based largely on reducing material cost and extending cell calendar life, relative to our Gen 1 cell chemistry. Table 1 provides a list of the materials used in our Gen 2 cell chemistry and their projected costs, when produced in large-scale quantities. In evaluating advanced materials, we have focused our efforts on materials that are lower cost than those listed in Table 1, while simultaneously offering enhanced chemical, structural, and thermal stability. Therefore, we have focused on natural graphite anode materials (having round-edge particle morphologies), cathode materials that contain more Mn and less Co and Ni (which can be produced via low-cost processes), lower cost electrode binders and/or binders that possess superior bonding properties at lower concentrations, and lower cost salts and solvents (with superior thermal and oxidation/reduction stability) for use in the electrolyte. The purpose of this report is to document the results of screening tests that were performed on a large number of advanced low-cost materials. These materials were screened for their potential to impact positively on the calendar life, safety, and/or cost of high-power lithium-ion cell chemistries, relative to our Gen 2 cell chemistry. As part of this effort, we developed and employed a set of standard test protocols to evaluate all of the materials. After brief descriptions of the screening test methodologies and equipment, relevant data on each material are summarized in the body of this report. We have evaluated five categories of materials, and the report is organized accordingly. Results will be presented on advanced carbons for anodes, improved cathode materials, new salts and solvent systems, alternative binders, and novel separators.

Annual Site Environmental Report Calendar Year 2007  

Science Conference Proceedings (OSTI)

This report summarizes the environmental status of Ames Laboratory for calendar year 2007. It includes descriptions of the Laboratory site, its mission, the status of its compliance with applicable environmental regulations, its planning and activities to maintain compliance, and a comprehensive review of its environmental protection, surveillance and monitoring activities. Ames Laboratory is located on the campus of Iowa State University (ISU) and occupies 11 buildings owned by the Department of Energy (DOE). See the Laboratory's Web page at www.external.ameslab.gov for locations and Laboratory overview. The Laboratory also leases space in ISU owned buildings. In 2007, the Laboratory accumulated and disposed of waste under U.S. Environmental Protection Agency (EPA) issued generator numbers. All waste is handled according to all applicable EPA, State, Local and DOE Orders. In 2006 the Laboratory reduced its generator status from a Large Quantity Generator (LQG) to a Small Quantity Generator (SQG). EPA Region VII was notified of this change. The Laboratory's RCRA hazardous waste management program was inspected by EPA Region VII in April 2006. There were no notices of violations. The inspector was impressed with the improvements of the Laboratory's waste management program over the past ten years. The Laboratory was in compliance with all applicable federal, state, local and DOE regulations and orders in 2007. There were no radiological air emissions or exposures to the general public due to Laboratory activities in 2007. See U.S. Department of Energy Air Emissions Annual Report in Appendix B. As indicated in prior SERs, pollution awareness, waste minimization and recycling programs have been in practice since 1990, with improvements implemented most recently in 2003. Included in these efforts were battery and CRT recycling, waste white paper and green computer paper-recycling. Ames Laboratory also recycles/reuses salvageable metal, used oil, styrofoam peanuts, batteries, fluorescent lamps and telephone books. Ames Laboratory reported to DOE-Ames Site Office (AMSO), through the Laboratory's Self Assessment Report, on its Affirmative Procurement Performance Measure. A performance level of 'A' was achieved in 2007 for Integrated Safety, Health, and Environmental Protection. As reported in Site Environmental Reports for prior years, the Laboratory's Environmental Management System has been integrated into the Laboratory's Integrated Safety Management System since 2005. The integration of EMS into the way the Laboratory does business allows the Laboratory to systematically review, address and respond to the Laboratory's environmental impacts.

Smart battery controller for lithium/sulfur dioxide batteries  

Science Conference Proceedings (OSTI)

Each year, the U.S. Army purchases millions of lithium sulfur dioxide batteries for use in portable electronics equipment. Because of their superior rate capability and service life over a wide variety of conditions, lithium batteries are the power source of choice for military equipment. There is no convenient method of determining the available energy remaining in partially used lithium batteries; hence, users do not take full advantage of all the available battery energy. Currently, users replace batteries before each mission, which leads to premature disposal, and results in the waste of millions of dollars in battery energy every year. Another problem of the lithium battery is that it is necessary to ensure complete discharge of the cells when the useful life of the battery has been expended, or when a hazardous condition exists; a hazardous condition may result in one or more of the cells venting. The Electronics Technology and Devices Laboratory has developed a working prototype of a smart battery controller (SBC) that addresses these problems.

Life-cycle cost comparisons of advanced storage batteries and fuel cells for utility, stand-alone, and electric vehicle applications  

DOE Green Energy (OSTI)

This report presents a comparison of battery and fuel cell economics for ten different technologies. To develop an equitable economic comparison, the technologies were evaluated on a life-cycle cost (LCC) basis. The LCC comparison involved normalizing source estimates to a standard set of assumptions and preparing a lifetime cost scenario for each technology, including the initial capital cost, replacement costs, operating and maintenance (O M) costs, auxiliary energy costs, costs due to system inefficiencies, the cost of energy stored, and salvage costs or credits. By considering all the costs associated with each technology over its respective lifetime, the technology that is most economical to operate over any given period of time can be determined. An analysis of this type indicates whether paying a high initial capital cost for a technology with low O M costs is more or less economical on a lifetime basis than purchasing a technology with a low initial capital cost and high O M costs. It is important to realize that while minimizing cost is important, the customer will not always purchase the least expensive technology. The customer may identify benefits associated with a more expensive option that make it the more attractive over all (e.g., reduced construction lead times, modularity, environmental benefits, spinning reserve, etc.). The LCC estimates presented in this report represent three end-use applications: utility load-leveling, stand-alone power systems, and electric vehicles.

9. annual battery conference on advances and applications  

SciTech Connect

The developments in batteries reported at the 9th Annual Battery Conference on Advances and Applications, are discussed. It was sponsored by the Electrical Engineering Department of California State University, Long Beach, CA, with IEEE-AESS cooperation. Previous well-funded battery research had been directed toward getting low weight in spacecraft batteries, which had to be boosted into orbit with expensive rockets. Ni-H{sub 2} batteries, even though costly, won the race. Their demonstrated life, like 30,000 charge-discharge cycles, gives an earth-orbiting satellite decades of usable life. Other types of batteries discussed are: aircraft batteries; electric vehicle batteries; Ni-Cd cells; Zn-Br batteries; industrial Pb-acid batteries; rechargeability; computer controlled charging; and small rechargeable and primary batteries.

Attempting clairvoyance with battery performance  

E-Print Network (OSTI)

The light-weight, long-lasting, high-performance attributes of cellular phones and laptop computers, among other equally impressive portable devices currently in the marketplace, are responsible for igniting the overwhelming growth of the battery-powered electronics industry. The demand for smaller and longer lasting solutions, in fact, is only increasing, and key to this success is the battery, which can range from single-use alkaline and zinc-air to rechargeable nickel-cadmium, nickel-metal hydride, lithium-ion, and lithium-polymer technologies. Unfortunately, however, advancements in circuit and system integration have outpaced energy and power density improvements in the battery. Consequently, as batteries conform to the size constraints of portable applications, capacity and output power are necessarily compromised. Degradation in battery performance over time not only affects functionality but also operational life, proving inadequate the traditional assumption that the battery is an ideal voltage source. Including the effects of the battery on state-of-theart systems during the design phase is therefore of increasing importance for optimal life and performance. The problem is securing a suitable Cadence-compatible model. Battery Models State-of-the-art electrical models for batteries are either Thevenin-, impedance-, or runtime-based. Thevenin- and impedance-based models, shown in Figures 1(a)-(b), assume both open-circuit voltage and capacity or state-of-charge (SOC) are constant and approximate loading and ac/transient effects with an impedance network of passive devices for

Iron-Air Rechargeable Battery: A Robust and Inexpensive Iron-Air Rechargeable Battery for Grid-Scale Energy Storage  

Science Conference Proceedings (OSTI)

GRIDS Project: USC is developing an iron-air rechargeable battery for large-scale energy storage that could help integrate renewable energy sources into the electric grid. Iron-air batteries have the potential to store large amounts of energy at low costiron is inexpensive and abundant, while oxygen is freely obtained from the air we breathe. However, current iron-air battery technologies have suffered from low efficiency and short life spans. USC is working to dramatically increase the efficiency of the battery by placing chemical additives on the batterys iron-based electrode and restructuring the catalysts at the molecular level on the batterys air-based electrode. This can help the battery resist degradation and increase life span. The goal of the project is to develop a prototype iron-air battery at significantly cost lower than todays best commercial batteries.

Annual Site Environmental Report Calendar Year 2010  

Science Conference Proceedings (OSTI)

This report summarizes the environmental status of Ames Laboratory for calendar year 2010. It includes descriptions of the Laboratory site, its mission, the status of its compliance with applicable environmental regulations, its planning and activities to maintain compliance, and a comprehensive review of its environmental protection, surveillance and monitoring activities. In 2010, the Laboratory accumulated and disposed of waste under U.S. Environmental Protection Agency (EPA) issued generator numbers. All waste is handled according to all applicable EPA, State, Local regulations and DOE Orders. In 2006 the Laboratory reduced its generator status from a Large Quantity Generator (LQG) to a Small Quantity Generator (SQG). EPA Region VII was notified of this change. The Laboratory's RCRA hazardous waste management program was inspected by EPA Region VII in April 2006. There were no notices of violations. The inspector was impressed with the improvements of the Laboratory's waste management program over the past ten years. The Laboratory was in compliance with all applicable federal, state, local and DOE regulations and orders in 2010. There were no radiological air emissions or exposures to the general public due to Laboratory activities in 2010. See U.S. Department of Energy Air Emissions Annual Report in Appendix B. As indicated in prior SERs, pollution awareness, waste minimization and recycling programs have been in practice since 1990, with improvements implemented most recently in 2010. Included in these efforts were battery and CRT recycling, miscellaneous electronic office equipment, waste white paper and green computer paper-recycling and corrugated cardboard recycling. Ames Laboratory also recycles/reuses salvageable metal, used oil, foamed polystyrene peanuts, batteries, fluorescent lamps and telephone books. Ames Laboratory reported to DOE-Ames Site Office (AMSO), through the Laboratory's Performance Evaluation Measurement Plan, on its Affirmative Procurement Performance Measure. A performance level of 'A-' was achieved in 2010 for Integrated Safety, Health and Environmental Protection. As reported in Site Environmental Reports for prior years, the Laboratory's Environmental Management System (EMS) has been integrated into the Laboratory's Integrated Safety Management System since 2005. The integration of EMS into the way the Laboratory does business allows the Laboratory to systematically review, address and respond to the Laboratory's environmental impacts. The Laboratory's EMS was audited in April 2009 by DOE-CH. There were four 'Sufficiently in Conformity' findings as a result of the audit. All four findings were tracked in the Laboratory's corrective action database for completion. Beryllium was used routinely at Ames Laboratory in the 1940's and 1950's in processes developed for the production of highly pure uranium and thorium in support of the historic Manhattan Project. Laboratory metallurgists also worked on a process to produce pure beryllium metal from beryllium fluoride. In the early 1950's, beryllium oxide powder was used to produce shaped beryllium and crucibles. As a result of that work, beryllium contamination now exists in many interstitial spaces (e.g., utility chases) and ventilation systems in Wilhelm, Spedding and Metals Development buildings. Extensive characterization and remediation efforts have occurred in 2009 and 2010 in order to better understand the extent of the contamination. Analysis of extensive sampling data suggests that a fairly wide dispersion of beryllium occurred (most likely in the 1950's and 60's) in Wilhelm Hall and in certain areas of Spedding Hall and Metals Development. Area air-sampling results and work-area surface characterizations indicate the exposure potential to current workers, building visitors and the public remains extremely low. This information is now used to guide cleaning efforts and to provide worker protection during remodeling and maintenance activities. Results were shared with the DOE's Former Worker Program to support former worker medical test

Second use of transportation batteries: Maximizing the value of batteries for transportation and grid services  

SciTech Connect

Plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs) are expected to gain significant market share over the next decade. The economic viability for such vehicles is contingent upon the availability of cost-effective batteries with high power and energy density. For initial commercial success, government subsidies will be highly instrumental in allowing PHEVs to gain a foothold. However, in the long-term, for electric vehicles to be commercially viable, the economics have to be self-sustaining. Towards the end of battery life in the vehicle, the energy capacity left in the battery is not sufficient to provide the designed range for the vehicle. Typically, the automotive manufacturers indicated the need for battery replacement when the remaining energy capacity reaches 70-80%. There is still sufficient power (kW) and energy capacity (kWh) left in the battery to support various grid ancillary services such as balancing, spinning reserve, load following services. As renewable energy penetration increases, the need for such balancing services is expected to increase. This work explores optimality for the replacement of transportation batteries to be subsequently used for grid services. This analysis maximizes the value of an electric vehicle battery to be used as a transportation battery (in its first life) and then as a resource for providing grid services (in its second life). The results are presented across a range of key parameters, such as depth of discharge (DOD), number of batteries used over the life of the vehicle, battery life in vehicle, battery state of health (SOH) at end of life in vehicle and ancillary services rate. The results provide valuable insights for the automotive industry into maximizing the utility and the value of the vehicle batteries in an effort to either reduce the selling price of EVs and PHEVs or maximize the profitability of the emerging electrification of transportation.

Battery testing at Argonne National Laboratory  

SciTech Connect

Advanced battery technology evaluations are performed under simulated electric-vehicle operating conditions at the Analysis Diagnostic Laboratory (ADL) of Argonne National Laboratory. The ADL results provide insight into those factors that limit battery performance and life. The ADL facilities include a test laboratory to conduct battery experimental evaluations under simulated application conditions and a post-test analysis laboratory to determine, in a protected atmosphere if needed, component compositional changes and failure mechanisms. This paper summarizes the performance characterizations and life evaluations conducted during FY 1992 on both single cells and multi-cell modules that encompass six battery technologies [Na/S, Li/FeS, Ni/Metal-Hydride, Ni/Zn, Ni/Cd, Ni/Fe]. These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division, and the Electric Power Research Institute. The ADL provides a common basis for battery performance characterization and lie evaluations with unbiased application of tests and analyses. The results help identify the most promising R D approaches for overcoming battery limitations, and provide battery users, developers, and program managers with a measure of the progress being made in battery R D programs, a comparison of battery technologies, and basic data for modeling.

A User Programmable Battery Charging System  

E-Print Network (OSTI)

Rechargeable batteries are found in almost every battery powered application. Be it portable, stationary or motive applications, these batteries go hand in hand with battery charging systems. With energy harvesting being targeted in this day and age, high energy density and longer lasting batteries with efficient charging systems are being developed by companies and original equipment manufacturers. Whatever the application may be, rechargeable batteries, which deliver power to a load or system, have to be replenished or recharged once their energy is depleted. Battery charging systems must perform this replenishment by using very fast and efficient methods to extend battery life and to increase periods between charges. In this regard, they have to be versatile, efficient and user programmable to increase their applications in numerous battery powered systems. This is to reduce the cost of using different battery chargers for different types of battery powered applications and also to provide the convenience of rare battery replacement and extend the periods between charges. This thesis proposes a user programmable charging system that can charge a Lithium ion battery from three different input sources, i.e. a wall outlet, a universal serial bus (USB) and an energy harvesting system. The proposed charging system consists of three main building blocks, i.e. a pulse charger, a step down DC to DC converter and a switching network system, to extend the number of applications it can be used for. The switching network system is to allow charging of a battery via an energy harvesting system, while the step down converter is used to provide an initial supply voltage to kick start the energy harvesting system. The pulse charger enables the battery to be charged from a wall outlet or a USB network. It can also be reconfigured to charge a Nickel Metal Hydride battery. The final design is implemented on an IBM 0.18m process. Experimental results verify the concept of the proposed charging system. The pulse charger is able to be reconfigured as a trickle charger and a constant current charger to charge a Li-ion battery and a Nickel Metal Hydride battery, respectively. The step down converter has a maximum efficiency of 90% at an input voltage of 3V and the charging of the battery via an energy harvesting system is also verified.

Carbon-enhanced VRLA batteries.  

Science Conference Proceedings (OSTI)

The addition of certain forms of carbon to the negative plate in valve regulated lead acid (VRLA) batteries has been demonstrated to increase the cycle life of such batteries by an order of magnitude or more under high-rate, partial-state-of-charge operation. Such performance will provide a significant impact, and in some cases it will be an enabling feature for applications including hybrid electric vehicles, utility ancillary regulation services, wind farm energy smoothing, and solar photovoltaic energy smoothing. There is a critical need to understnd how the carbon interacts with the negative plate and achieves the aforementioned benefits at a fundamental level. Such an understanding will not only enable the performance of such batteries to be optimzied, but also to explore the feasibility of applying this technology to other battery chemistries. In partnership with the East Penn Manufacturing, Sandia will investigate the electrochemical function of the carbon and possibly identify improvements to its anti-sulfation properties. Shiomi, et al. (1997) discovered that the addition of carbon to the negative active material (NAM) substantially reduced PbSO{sub 4} accumulation in high rate, partial state of charge (HRPSoC) cycling applications. This improved performance with a minimal cost. Cycling applications that were uneconomical for traditional VRLA batteries are viable for the carbon enhanced VRLA. The overall goal of this work is to quantitatively define the role that carbon plays in the electrochemistry of a VRLA battery.

Batteries: Overview of Battery Cathodes  

SciTech Connect

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

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

Battery discharge characteristics of wireless sensor nodes: An experimental analysis  

E-Print Network (OSTI)

Abstract Battery life extension is the principal driver for energy-efficient wireless sensor network (WSN) design. However, there is growing awareness that in order to truly maximize the operating life of battery-powered systems such as sensor nodes, it is important to discharge the battery in a manner that maximizes the amount of charge extracted from it. In spite of this, there is little published data that quantitatively analyzes the effectiveness with which modern wireless sensor nodes discharge their batteries, under different operating conditions. In this paper, we report on systematic experiments that we conducted to quantify the impact of key wireless sensor network design and environmental parameters on battery performance. Our testbed consists of MICA2DOT Motes, a commercial lithiumcoin battery, and a suite of techniques for measuring battery performance. We evaluate the extent to which known electrochemical phenomena, such as rate-capacity characteristics, charge recovery and thermal effects, can play a role in governing the selection of key WSN design parameters such as power levels, packet sizes, etc. We demonstrate that battery characteristics significantly alter and complicate otherwise well-understood trade-offs in WSN design. In particular, we analyze the non-trivial implications of battery characteristics on WSN power control strategies, and find that a battery-aware approach to power level selection leads to a 52 % increase in battery efficiency. We expect our results to serve as a quantitative basis for future research in designing battery-efficient sensing applications and protocols. I.

Amorphous Hierarchical Porous GeOx as High-Capacity Anodes for LiIon Batteries with Very Long Cycling Life  

SciTech Connect

Many researchers have focused in recent years on resolving the crucial problem of capacity fading in Li ion batteries when carbon anodes are replaced by other group-IV elements (Si, Ge, Sn) with much higher capacities. Some progress was achieved by using different nanostructures (mainly carbon coatings), with which the cycle numbers reached 100-200. However, obtaining longer stability via a simple process remains challenging. Here we demonstrate that a nanostructure of amorphous hierarchical porous GeO{sub x} whose primary particles are {approx}3.7 nm diameter has a very stable capacity of {approx}1250 mA h g{sup -1} for 600 cycles. Furthermore, we show that a full cell coupled with a Li(NiCoMn){sub 1/3}O{sub 2} cathode exhibits high performance.

Smart battery controller for lithium/sulfur dioxide batteries. Technical report, Jan 89-Apr 91  

Science Conference Proceedings (OSTI)

Each year, the U.S. Army purchases millions of lithium sulfur dioxide batteries for use in portable electronics equipment. Because of their superior rate capability and service life over a wide variety of conditions, lithium batteries are the power source of choice for military equipment. There is no convenient method of determining the available energy remaining in partially used lithium batteries; hence, users do not take full advantage of all the available battery energy. Currently, users replace batteries before each mission, which leads to premature disposal, and results in the waste of millions of dollars in battery energy every year. Another problem of the lithium battery is that it is necessary to ensure complete discharge of the cells when the useful life of the battery has been expended, or when a hazardous condition exists; a hazardous condition may result in one or more of the cells venting. The Electronics Technology and Devices Laboratory has developed a working prototype of a smart battery controller (SBC) that addresses these problems.

Near-term batteries for electric vehicles  

SciTech Connect

Major progress has been achieved in the lead-acid , nickel/iron and nickel/zinc battery technology development since the initiation of the Near-Term eV Battery Project in 1978. Against the specific energy goal of 56 wh/kg the demonstrated specific energies are 41 wh/kg for the improved lead-acid batteries, 48 wh/kg for the improved nickel/iron batteries, and 68 wh/kg for the improved nickel/zinc batteries. These specific energy values would allow an ETV-1 vehicle to have an urban range of 80 miles in the case of the improved lead-acid batteries, 96 miles for the improved nickel/zinc batteries, and 138 miles for the improved lead-acid batteries. All represent a significant improvement over the state-of-the-art lead-acid battery capability of about 30 wh/kg with approximately a 51 mile urban range for the ETV-1 vehicle. The project goal for specific power of 104 w/kg for 30 seconds at a 50% depth of discharge has been achieved for all of the technologies with the improved lead-acid demonstrating 111 w/kg, the improved nickel/iron demonstrating 103 w/kg, and the improved nickel/zinc demonstrating 131 w/kg. Again this is a significant improvement over the state-of-the-art lead-acid battery capability of 70 w/kg. Substantial progress has been made against the life cycle goal of 800 cycles as evidenced by the demonstrated lead-acid battery achievement of > 295 cycles in ongoing tests, the nickel/iron demonstrated capability of > 515 cycles in ongoing tests, and the nickel/zinc demonstrated capability of 179 cycles. Except for the nickel/zinc batteries, the demonstrated cycle life is better than the state-of-the-art lead-acid battery cycle life of about 250 cycles. Future program emphases will be on improving cycle life and further reductions in cost.

Battery developments: The positive connection to a greener future  

SciTech Connect

Extraordinary innovations are being made in the performance of today`s portable electronic equipment. But, although electronics manufacturers have been leaping generations ahead of themselves technologically, they are still forced to look back to see battery technology struggling to close the distance that ever widens with each new electronics breakthrough. The need to improve battery performance, namely in the area of battery longevity, has stemmed from a growing consumer demand and has become one of the electronics industry`s newest challenges. Battery manufactures like Duracell, Ovonic Battery Company (OBC), Ergenics, Matsushita, and Sony Corporation are answering the call with research and development programs that will aid the transition to more efficient, environmentally friendly batteries. Traditionally, the market was dedicated to primary batteries, or non-rechargeable, disposable batteries that are composed of zinc-carbon, alkaline-manganese, mercury oxide, silver oxide, lithium metal, and lead-acid. Conventional lead-acid automotive batteries, while rechargeable, are toxic and not recyclable; new secondary battery designs will satisfy the needs of the electronics industry, while offering environmental benefits. The new types, such as rechargeable nickel metal-hydride (NiMH), lithium-ion, and lithium-polymer have longer life-cycles and are also recyclable. Zinc-air batteries, which are classified as primary batteries, are not rechargeable but offer substantial power and environmental benefits. Portable computers, cellular telephones, video camcorders, stereo equipment, and LCD televisions are a few of the many practical applications that will benefit from new battery technology.

Thermal control of electric vehicle batteries  

DOE Green Energy (OSTI)

The need to operate electric vehicles in warm, summer conditions and also provide for long periods of standby in cold climates is a challenging problem for any battery system. All advanced batteries of high specific energy require active cooling systems because adiabatic heating will raise the temperature to a level that is deleterious to cycle life. This cooling requires efficient paths for escape of heat to cooled surfaces; cooling the exterior of modules is insufficient. If a battery is heated by its own energy, and insulated to withstand exposure to a cold climate, only vacuum insulation will afford an appreciable reduction (>10{degrees}C) in the ambient temperature that can be tolerated. Standard insulations are of little use for this purpose because the heat loss rate causes too high a drain on the battery energy even for near-ambient temperature batteries.

SYSPLAN. Load Leveling Battery System Costs  

SciTech Connect

SYSPLAN evaluates capital investment in customer side of the meter load leveling battery systems. Such systems reduce the customer`s monthly electrical demand charge by reducing the maximum power load supplied by the utility during the customer`s peak demand. System equipment consists of a large array of batteries, a current converter, and balance of plant equipment and facilities required to support the battery and converter system. The system is installed on the customer`s side of the meter and controlled and operated by the customer. Its economic feasibility depends largely on the customer`s load profile. Load shape requirements, utility rate structures, and battery equipment cost and performance data serve as bases for determining whether a load leveling battery system is economically feasible for a particular installation. Life-cycle costs for system hardware include all costs associated with the purchase, installation, and operation of battery, converter, and balance of plant facilities and equipment. The SYSPLAN spreadsheet software is specifically designed to evaluate these costs and the reduced demand charge benefits; it completes a 20 year period life cycle cost analysis based on the battery system description and cost data. A built-in sensitivity analysis routine is also included for key battery cost parameters. The life cycle cost analysis spreadsheet is augmented by a system sizing routine to help users identify load leveling system size requirements for their facilities. The optional XSIZE system sizing spreadsheet which is included can be used to identify a range of battery system sizes that might be economically attractive. XSIZE output consisting of system operating requirements can then be passed by the temporary file SIZE to the main SYSPLAN spreadsheet.

Efficient Power Profiling for Battery-Driven Embedded System Design  

E-Print Network (OSTI)

The ability to efficiently and accurately estimate battery life under different design choices at the system level is an important aid in designing battery-efficient systems. Recently developed battery models help by estimating battery life under given profiles of the battery discharge current over time. However, existing techniques for energy (or average power) estimation do not provide sufficient information (such as time profiles of system power consumption) to drive battery-life estimation. Techniques that are capable of generating such profiles often lack the efficiency required to support exploration at the system level. In this paper, we describe techniques for efficient generation of system-level power profiles, for use in a battery-life estimation framework. Our power profiling technique allows a designer to experiment with: 1) the mapping of system tasks to a set of architectural components and 2) the mapping of system communications to a specified communication architecture, and efficiently generate system power profiles for each alternative. The resulting profiles can then be analyzed using existing battery models to estimate battery lifetime and capacity. Extensive experiments conducted on an IEEE 802.11 MAC processor design demonstrate that our power profiler offers orders of magnitude improvement in runtimes over state-of-the-art cosimulation-based power estimation techniques, while suffering minimal loss of accuracy (average profiling error was 3.8%).

Recommended mission directed goals for electric vehicle battery research and development. The task force on electric vehicle battery goals  

SciTech Connect

Research and development goal packages were developed for the state-of-the-art, flow-through, and bipolar lead-acid batteries, nickel/iron, nickel/zinc, nickel/cadmium, zinc/bromine, iron/air, lithium/iron sulfide, and sodium/sulfur technologies. Since each battery must satisfy mission power/energy requirements throughout every cycle of its operating life, the principal ''design point'' is the end-of-life condition. Since all batteries exhibit deteriorating performance with age, excess kWh capacity of 20 to 30 percent is required early in life. The Battery Panel first identified present state-of-the-art performance characteristics and design interrelationships for each battery technology, and projected the degree of advance expected by 1995. Near-term and 1995 design tradeoffs were modeled using the EVA computerized system developed by ANL. The next step was to target each battery system for a single range (80, 120 or 160 km), depending on its projected 1995 capabilities. For each battery, baseline calculations were carried out assuming the maximum battery weight (695 kg) to be on board. In addition to performance, life, and cost goals, development targets were also established for efficiency, maintenance, and allowable self-discharge rate. The Task Force attempted to establish battery cost requirements, assuming economic parity (in 1995) with other modes of transportation.

Two Studies Reveal Details of Lithium-Battery Function  

NLE Websites -- All DOE Office Websites (Extended Search)

Two Studies Reveal Details of Lithium-Battery Function Print Two Studies Reveal Details of Lithium-Battery Function Print Our way of life is deeply intertwined with battery technologies that have enabled a mobile revolution powering cell phones, laptops, medical devices, and cars. As conventional lithium-ion batteries approach their theoretical energy-storage limits, new technologies are emerging to address the long-term energy-storage improvements needed for mobile systems, electric vehicles in particular. Battery performance depends on the dynamics of evolving electronic and chemical states that, despite advances in material synthesis and structural probes, remain elusive and largely unexplored. At Beamlines 8.0.1 and 9.3.2, researchers studied lithium-ion and lithium-air batteries, respectively, using soft x-ray spectroscopy techniques. The detailed information they obtained about the evolution of electronic and chemical states will be indispensable for understanding and optimizing better battery materials.

Battery modeling for electric vehicle applications using neural networks  

SciTech Connect

Neural networking is a new approach to modeling batteries for electric vehicle applications. This modeling technique is much less complex then a first principles model but can consider more parameters then classic empirical modeling. Test data indicates that individual cell size and geometry and operating conditions affect a battery performance (energy density, power density and life). Given sufficient battery data, system parameters and operating conditions a neural network model could be used to interpolate and perhaps even extrapolate battery performance under wide variety of operating conditions. As a result the method could be a valuable design tool for electric vehicle battery design and application. This paper describes the on going modeling method at Texas A and M University and presents preliminary results of a tubular lead acid battery model. The ultimate goal of this modeling effort is to develop the values necessary to be able to predict performance for batteries as wide ranging as sodium sulfur to zinc bromine.

Improving Battery Design with Electro-Thermal Modeling  

DOE Green Energy (OSTI)

Temperature greatly affects the performance and life of batteries in electric and hybrid vehicles under real driving conditions, so increased attention is being paid to battery thermal management. Sophisticated electrochemical models and finite element analysis tools are available for predicting the thermal performance of batteries, but each has limitations. In this study we describe an electro-thermal finite element approach that predicts the thermal performance of a cell or module with realistic geometry, material properties, loads, and boundary conditions.

Results of advanced battery technology evaluations for electric vehicle applications  

SciTech Connect

Advanced battery technology evaluations are performed under simulated electric-vehicle operating conditions at the Analysis & Diagnostic Laboratory (ADL) of Argonne National Laboratory. The ADL results provide insight Into those factors that limit battery performance and life. The ADL facilities include a test laboratory to conduct battery experimental evaluations under simulated application conditions and a post-test analysis laboratory to determine, In a protected atmosphere if needed, component compositional changes and failure mechanisms. This paper summarizes the performance characterizations and life evaluations conducted during 1991--1992 on both single cells and multi-cell modules that encompass eight battery technologies [Na/S, Li/MS (M=metal), Ni/MH, Ni/Cd, Ni/Zn, Ni/Fe, Zn/Br, and Pb-acid]. These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division, and the Electric Power Research Institute. The ADL provides a common basis for battery performance characterization and life evaluations with unbiased application of tests and analyses. The results help identify the most-promising R&D approaches for overcoming battery limitations, and provide battery users, developers, and program managers with a measure of the progress being made in battery R&D programs, a comparison of battery technologies, and basic data for modeling.

SciTech Connect

In an exemplary embodiment, a battery monitoring system includes sensors for monitoring battery parameters and a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle, and by monitoring battery current thereafter during operation, a relatively accurate measure of remaining battery capacity becomes available. The battery monitoring system may include programmed processor circuitry and may be secured to the battery so as to receive operating power therefrom during storage and handling; thus, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters.

Recycling readiness of advanced batteries for electric vehicles  

SciTech Connect

Maximizing the reclamation/recycle of electric-vehicle (EV) batteries is considered to be essential for the successful commercialization of this technology. Since the early 1990s, the US Department of Energy has sponsored the ad hoc advanced battery readiness working group to review this and other possible barriers to the widespread use of EVs, such as battery shipping and in-vehicle safety. Regulation is currently the main force for growth in EV numbers and projections for the states that have zero-emission vehicle (ZEV) programs indicate about 200,000 of these vehicles would be offered to the public in 2003 to meet those requirements. The ad hoc Advanced Battery Readiness Working Group has identified a matrix of battery technologies that could see use in EVs and has been tracking the state of readiness of recycling processes for each of them. Lead-acid, nickel/metal hydride, and lithium-ion are the three EV battery technologies proposed by the major automotive manufacturers affected by ZEV requirements. Recycling approaches for the two advanced battery systems on this list are partly defined, but could be modified to recover more value from end-of-life batteries. The processes being used or planned to treat these batteries are reviewed, as well as those being considered for other longer-term technologies in the battery recycling readiness matrix. Development efforts needed to prepare for recycling the batteries from a much larger EV population than exists today are identified.

Hardware Architecture for Measurements for 50-V Battery Modules  

SciTech Connect

Energy storage devices, especially batteries, have become critical for several industries including automotive, electric utilities, military and consumer electronics. With the increasing demand for electric and hybrid electric vehicles and the explosion in popularity of mobile and portable electronic devices such as laptops, cell phones, e-readers, tablet computers and the like, reliance on portable energy storage devices such as batteries has likewise increased. Because many of the systems these batteries integrated into are critical, there is an increased need for an accurate in-situ method of monitoring battery state-of-health. Over the past decade the Idaho National Laboratory (INL), Montana Tech of the University of Montana (Tech), and Qualtech Systems, Inc. (QSI) have been developing the Smart Battery Status Monitor (SBSM), an integrated battery management system designed to monitor battery health, performance and degradation and use this knowledge for effective battery management and increased battery life. Key to the success of the SBSM is an in-situ impedance measurement system called the Impedance Measurement Box (IMB). One of the challenges encountered has been development of a compact IMB system that will perform rapid accurate measurements of a battery impedance spectrum working with higher voltage batteries of up to 300 volts. This paper discusses the successful realization of a system that will work up to 50 volts.

A battery energizer for button batteries, such as zinc-silver oxide or zinc-mercuric oxide batteries, that are normally considered unchargeable, provides for energizing of the batteries in a safe and simple manner. A solar cell having a maximum current output (e.g., 20 milliamps) is operatively connected to terminals for releasably receiving a button battery. A light emitting diode, or like indicator, provides an indication of when the battery is fully energized, and additionally assists in preventing overenergization of the battery. The solar cell, terminals, LED, and the like can be mounted on a nonconductive material mounting plate which is mounted by a suction cup and hook to a window, adjacent a light bulb, or the like. A battery charger for conventional dry cell rechargeable batteries (such as nickel-cadmium batteries) utilizes the solar cells, and LED, and a zener diode connected in parallel with terminals. An adaptor may be provided with the terminal for adapting them for use with any conventional size dry cell battery, and a simple dummy battery may be utilized so that less than the full complement of batteries may be charged utilizing the charger.

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.

Progress and forecast in electric-vehicle batteries  

SciTech Connect

With impetus provided by US Public Law 94-413 (Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976), the Department of Energy (DOE) launched a major battery development program early in 1978 for near-term electric vehicles. The program's overall objective is to develop commercially viable batteries for commuter vehicles (with an urban driving range of 100 miles) and for vans and trucks (with a range of 50 miles) by the mid-1980's. Three near-term battery candidates are receiving major developmental emphasis - improved lead-acid, nickel/iron and nickel/zinc systems. Sharing the cost with the government, nine industrial firms (battery developers) are participating in the DOE battery project. They are Eltra Corp., Exide Management and Technology Co., and Globe-Union Inc., for the lead-acid battery; Eagle-Picher Industries, Inc., and Westinghouse Electric Corp. for the nickel/iron battery; and Energy Research Corp., Exide Management and Technology Co., and Gould Inc., for the nickel/zinc battery. Good progress has been made in improving the specific energy, specific power, and manufacturing processes of these three battery technologies. Current emphasis is directed toward reduction of manufacturing cost and enhancement of battery cycle life and reliability. Recently, the zinc-chloride battery was added as the fourth candidate to the near-term battery list. Testing of the zinc-chloride battery in a vehicle and evaluation of its operating characteristics are currently under way. This paper presents the development goals, the status, and the outlook for the near-term battery program.

To make electricity, they depended exclusively upon chemical reactions involving metal components of the battery. But today a revolutionary new type of battery is available commercially. It stores electricity in plastic. Plastic batteries are the most radical innovation in commercial batteries since the dry cell was introduced in 1890. Plastic batteries offer higher capacity, higher voltage, and longer shelf-life than many competitive designs. Companies are testing new shapes and configurations, including flat batteries, that can be bent like cardboard. Researchers expect that the new technology will free electronic designers from many of the constraints imposed by metal batteries such as limited recharging cycles, high weight, and high cost.

Recovery Act - Demonstration of Sodium Ion Battery for Grid Level Applications  

SciTech Connect

Aquion Energy received a $5.179 million cooperative research agreement under the Department of Energy??s Smart Grid Demonstration Program ?? Demonstration of Promising Energy Storage Technologies (Program Area 2.5) of FOA DE-FOE-0000036. The main objective of this project was to demonstrate Aquion??s low cost, grid-scale, ambient temperature sodium ion energy storage device. The centerpiece of the technology is a novel hybrid energy storage chemistry that has been proven in a laboratory environment. The objective was to translate these groundbreaking results from the small-batch, small-cell test environment to the pilot scale to enable significant numbers of multiple ampere-hour cells to be manufactured and assembled into test batteries. Aquion developed a proof of concept demonstration unit that showed similar performance and major cost improvement over existing technologies. Beyond minimizing cell and system cost, Aquion built a technology that is safe, environmentally benign and durable over many thousands of cycles as used in a variety of grid support roles. As outlined in the Program documents, the original goals of the project were to demonstrate a unit that: 1. Has a projected capital cost of less than $250/kWh at the pack level 2. A deep discharge cycle life of > 10,000 cycles 3. A volumetric energy density of >20 kWh/m3 4. Projected calendar life of over 10 years 5. A device that contains no hazardous materials and retains best in class safety characteristics. Through the course of this project Aquion developed its aqueous electrolyte electrochemical energy storage device to the point where large demonstration units (> 10 kWh) were able to function in grid-supporting functions detailed by their collaborators. Aquion??s final deliverable was an ~15 kWh system that has the ability to perform medium to long duration (> 2 hours) charge and discharge functions approaching 95% DC-DC efficiency. The system has functioned, and continues to function as predicted with no indication that it will not tolerate well beyond 10 calendar years and 10,000 cycles. It has been in continuous operation for more than 1 year with 1,000 cycles (of varying depth of discharge, including 100% depth of discharge) and no identifiable degradation to the system. The final thick electrode cell structure has shown an energy density of 25 kWh/m3 at a five hour (or greater) discharge time. The primary chemistry has remained non-toxic, containing no acids or other corrosive chemicals, and the battery units have passed numerous safety tests, including flame resistance testing. These tests have verified the claim that the device is safe to use and contains no hazardous materials. Current projections show costs at the pack level to offer best in class value and are competitive with lead-acid batteries, factoring in LCOE.

Industrial battery stack  

SciTech Connect

A novel industrial battery stack is disclosed, wherein positive plates which have been longitudinally wrapped with a perforate or semi-perforate material are accurately aligned with respect to the negative plates and separators in the stack during the stacking operation. The novel spacing members of the present invention have a generally U-shaped cross section for engaging through the wrapping a portion of the positive plate adjacent to the longitudinal edges of that plate. Projections protruding substantially from the base of the ''U'' provide the proper distance between the edge of the wrapped plate and an adjacent longitudinal surface. During the stacking and burning operation, this longitudinal surface comprises the back wall of a novel industrial battery plate holder. Following the burning of the battery stack and its subsequent assembly into an appropriate industrial battery case, the spacing member or members act to protect the positive battery plates and retain them in their proper alignment during the operation of the battery. Applicants have also provided a novel apparatus and method for stacking, aligning and burning industrial battery stacks which comprises a battery stack holder having several upstanding walls which define a stacking column having a coplanar terminus. An adjustably locatable partition within said stacking column may be disposed at any of a plurality of positions parallel with respect to the coplanar terminus so that the battery stack holder may be adjusted for any of a variety of given sizes of plates and separators. The battery plates and separators may then be stacked into the battery stack holder so that only the plate lugs extrude beyond the coplanar terminus. A dam is insertable along the top of the battery plates and across the top of the upstanding side walls of the battery stack holder to facilitate the rapid efficient burning of the industrial battery stack.

Performance Analysis of Battery Power Management Schemes in Wireless Mobile Devices  

E-Print Network (OSTI)

In this paper, we analyze the performance of battery power management schemes in wireless mobile devices using a queueing theory approach. We model the battery as a server with finite service capacity and data packets as customers to be served. With an intent to exploit the recharging capability of the battery when left idle, we allow the battery to go on intentional vacations during which the battery can recharge itself. The recharge thus built up can effectively increase the number of customers served (in other words, battery life can be extended). Such improved battery life performance would, however, come at the expense of increased packet delay performance. We quantify the battery life gain versus delay performance trade-off in this approach through analysis and simulations. By considering a continuous recharge model of the battery, we derive expressions for the number of customers served and the mean delay for an M=GI=1 queueing system without and with server vacations. We show that allowing intentional vacations during busy periods helps to increase battery life, and that this approach can be beneficial when applied on traffic of delay-tolerant applications. We also propose a packet delay constrained power saving algorithm that will exploit the recharge phenomenon when packet delay constraints are imposed. I.

Status of improved lead-acid, nickel/iron, and nickel/zinc batteries being developed under DOE's electric vehicle battery program  

SciTech Connect

The significant progress achieved in each of the three battery systems since the initiation of this battery development program is described. The 1982 demonstrated accomplishments are verified test results obtained on multicell modules (typically three to six cells each) at NBTL through May 1982. In particular, significant technical progress has been made in extending battery life. Additional progress in cell development and battery subsystem design (chargers, watering systems, electrolyte management systems) has allowed the construction of full-size battery packs. Globe Battery Division (lead-acid), Westinghouse (nickel/iron), and Eagle-Picher (nickel/iron) delivered full-size batteries to the Jet Propulsion Laboratory (JPL) for in-vehicle testing and evaluation.

Monitoring apparatus and method for battery power supply  

SciTech Connect

A monitoring apparatus and method are disclosed for monitoring and/or indicating energy that a battery power source has then remaining and/or can deliver for utilization purposes as, for example, to an electric vehicle. A battery mathematical model forms the basis for monitoring with a capacity prediction determined from measurement of the discharge current rate and stored battery parameters. The predicted capacity is used to provide a state-of-charge indication. Self-calibration over the life of the battery power supply is enacted through use of a feedback voltage based upon the difference between predicted and measured voltages to correct the battery mathematical model. Through use of a microprocessor with central information storage of temperature, current and voltage, system behavior is monitored, and system flexibility is enhanced.

One Million PHEVs by 2015: Challenges for Advanced Battery Technology  

DOE Green Energy (OSTI)

Lithium-ion batteries for hybrid electric vehicles (HEVs) have recently reached commercialization. R&D focus remains on cost reduction and improved abuse tolerance. DOE's battery R&D program has evolved to focus on high-energy plug-in hybrid electric vehicle (PHEV) systems. Li-ion represents the most promising chemistry for PHEVs because of its high energy density, high power capability and potential longer life & lower cost. Lack of domestic battery manufacturing remains a significant challenge. The 2009 Economic Recovery Act provides significant funding to address it. Long term success of PHEV & electric vehicle (EV) Li-ion batteries depends on further cost reduction and performance/life/safety improvements. Multi-physics CAE modeling is key enabler.

Nickel-metal hydride battery development. Final technical report  

SciTech Connect

Rechargeable batteries are used as the power source for a broad range of portable equipment. Key battery selection criteria typically are weight, volume, first cost, life cycle cost, and environmental impact. Rechargeable batteries are favored from a life cycle cost and environmental impact standpoint over primary batteries. The nickel-metal hydride (Ni-MH) battery system has emerged as the battery of choice for many applications based on its superior characteristics when judged on the above criteria against other battery types. In most cases commercial Ni-MH batteries are constructed with coiled electrodes in cylindrical metal containers. Electro Energy, Inc. (EEI) has been developing a novel flat bipolar configuration of the Ni-MH system that offers weight, volume, and cost advantages when compared to cylindrical cells. The unique bipolar approach consists of fabricating individual flat wafer cells in conductive, carbon-filled, plastic face plates. The individual cells contain a nonconductive plastic border which is heat sealed around the perimeter to make a totally sealed unit cell. Multi-cell batteries are fabricated by stacking the individual wafer cells in such a way that the positive face of one cell contacts the negative face of the adjacent cell. The stack is then contained in an outer housing with end contacts. The purpose of this program was to develop, evaluate, and demonstrate the capabilities of the EEI Ni-MH battery system for consumer applications. The work was directed at the development and evaluation of the compact bipolar construction for its potential advantages of high power and energy density. Experimental investigations were performed on various nickel electrode types, hydride electrode formulations, and alternate separator materials. Studies were also directed at evaluating various oxygen recombination techniques for low pressure operation during charge and overcharge.

Condition responsive battery charging circuit  

SciTech Connect

A battery charging circuit includes a ferroresonant transformer having a rectified output for providing a constant output voltage to be supplied to a battery to be charged. Battery temperature is sensed providing an input to a control circuit which operates a shunt regulator associated with the ferroresonant transformer to provide battery charge voltage as a function of battery temperature. In response to a high battery temperature the controller functions to lower the output voltage to the battery, and in response to a low battery temperature, operates to provide a higher output voltage, with suitable control for any battery temperature between minus 10* and plus 150* fahrenheit. As the battery approaches full charge and battery acceptance current falls below a predetermined level, a charge cycle termination control allows charging to continue for a period preset by the operator, at the end of which period, line voltage is removed from the charger thereby terminating the charge cycle.

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

Advanced Technology Development Program for Lithium-Ion Batteries: Gen 2 Performance Evaluation Final Report  

Science Conference Proceedings (OSTI)

The Advanced Technology Development Program has completed performance testing of the second generation of lithium-ion cells (i.e., Gen 2 cells). The 18650-size Gen 2 cells, with a baseline and variant chemistry, were distributed over a matrix consisting of three states-of-charge (SOCs) (60, 80, and 100% SOC), four temperatures (25, 35, 45, and 55C), and three life tests (calendar-, cycle-, and accelerated-life). The calendar- and accelerated-life cells were clamped at an open-circuit voltage corresponding to the designated SOC and were subjected to a once-per-day pulse profile. The cycle-life cells were continuously pulsed using a profile that was centered around 60% SOC. Life testing was interrupted every four weeks for reference performance tests (RPTs), which were used to quantify changes in cell degradation as a function of aging. The RPTs generally consisted of C1/1 and C1/25 static capacity tests, a low-current hybrid pulse power characterization test, and electrochemical impedance spectroscopy. The rate of cell degradation generally increased with increasing test temperature, and SOC. It was also usually slowest for the calendar-life cells and fastest for the accelerated-life cells. Detailed capacity-, power-, and impedance-based performance results are reported.

DOE-sponsored battery R and D: recent advances  

SciTech Connect

The main thrust of the battery research is in electric and hybrid vehicles. At the same time, batteries are being developed for utility load leveling and photovoltaic storage. Electric vehicle battery technology will be advanced in the late 1980's through RandD. Key battery development goals, based on the requirements of a passenger vehicle with a 100 mile range, acceptable performance, and a reasonable life cycle cost, are a specific energy of 56 Wh/kg (C/3 rate), a specific peak power for 30 seconds of 104 W/kg, a life of 800 cycles (80% depth of discharge), and an OEM price of /70/Wh-hr. Since 1978, differing technical approaches directed at achieving the battery goals have been pursued by each of the nine RandD contractors (three lead-acid, two nickel/iron, three nickel/zinc, and one zinc/chloride). RandD emphasis is placed on specific energy/power for lead-acid, cost for nickel/iron, cycle life for nickel/zinc, and packaging design and system control for the zinc/chloride battery. The article reviews progress by 12 laboratories.

Modeling of lead-acid battery capacity loss in a photovoltaic application  

SciTech Connect

The authors have developed a model for the probabilistic behavior of a rechargeable battery acting as the energy storage component in a photovoltaic power supply system. Stochastic and deterministic models are created to simulate the behavior of the system components. The components are the solar resource, the photovoltaic power supply system, the rechargeable battery, and a load. One focus of this research is to model battery state of charge and battery capacity as a function of time. The capacity damage effect that occurs during deep discharge is introduced via a non-positive function of duration and depth of deep discharge events. Because the form of this function is unknown and varies with battery type, the authors model it with an artificial neural network (ANN) whose parameters are to be trained with experimental data. The battery capacity loss model will be described and a numerical example will be presented showing the predicted battery life under different PV system use scenarios.

The 10 projects in ARPA-Es BEEST Project, short for Batteries for Electrical Energy Storage in Transportation, could make that happen by developing a variety of rechargeable battery technologies that would enable EV/PHEVs to meet or beat the price and performance of gasoline-powered cars, and enable mass production of electric vehicles that people will be excited to drive.

Analysis of batteries for use in photovoltaic systems. Final report  

SciTech Connect

An evaluation of 11 types of secondary batteries for energy storage in photovoltaic electric power systems is given. The evaluation was based on six specific application scenarios which were selected to represent the diverse requirements of various photovoltaic systems. Electrical load characteristics and solar insulation data were first obtained for each application scenario. A computer-based simulation program, SOLSIM, was then developed to determine optimal sizes for battery, solar array, and power conditioning systems. Projected service lives and battery costs were used to estimate life-cycle costs for each candidate battery type. The evaluation considered battery life-cycle cost, safety and health effects associated with battery operation, and reliability/maintainability. The 11 battery types were: lead-acid, nickel-zinc, nickel-iron, nickel-hydrogen, lithium-iron sulfide, calcium-iron sulfide, sodium-sulfur, zinc-chlorine, zinc-bromine, Redox, and zinc-ferricyanide. The six application scenarios were: (1) a single-family house in Denver, Colorado (photovoltaic system connected to the utility line); (2) a remote village in equatorial Africa (stand-alone power system); (3) a dairy farm in Howard County, Maryland (onsite generator for backup power); (4) a 50,000 square foot office building in Washington, DC (onsite generator backup); (5) a community in central Arizona with a population of 10,000 (battery to be used for dedicated energy storage for a utility grid-connected photovoltaic power plant); and (6) a military field telephone office with a constant 300 W load (trailer-mounted auxiliary generator backup). Recommendations for a research and development program on battery energy storage for photovoltaic applications are given, and a discussion of electrical interfacing problems for utility line-connected photovoltaic power systems is included.

High power battery test methods for hybrid vehicle applications  

DOE Green Energy (OSTI)

Commonly used EV battery tests are not very suitable for testing hybrid vehicle batteries, which may be primarily intended to supply vehicle acceleration power. The capacity of hybrid vehicle batteries will be relatively small, they will typically operate over a restricted range of states-of-charge, and they may seldom if ever be fully recharged. Further, hybrid propulsion system designs will commonly impose a higher regeneration content than is typical for electric vehicles. New test methods have been developed for use in characterizing battery performance and life for hybrid vehicle use. The procedures described in this paper were developed from the requirements of the government-industry cooperative Partnership for A New Generation of Vehicles (PNGV) program; however, they are expected to have broad application to the testing of energy storage devices for hybrid vehicles. The most important performance measure for a high power battery is its pulse power capability as a function of state-of-charge for both discharge and regeneration pulses. It is also important to characterize cycle life, although the {open_quote}cycles{close_quote} involved are quite different from the conventional full-discharge, full-recharge cycle commonly used for EV batteries, This paper illustrates in detail several test profiles which have been selected for PNGV battery testing, along with some sample results and lessons learned to date from the use of these test profiles. The relationship between the PNGV energy storage requirements and these tests is described so that application of the test methods can be made to other hybrid vehicle performance requirements as well. The resulting test procedures can be used to characterize the pulse power capability of high power energy storage devices including batteries and ultracapacitors, as well as the life expectancy of such devices, for either power assist or dual mode hybrid propulsion system designs.

Battery testing at Argonne National Laboratory. Electric and hybrid propulsion systems, No. 1  

SciTech Connect

Advanced battery technology evaluations are performed under simulated electric-vehicle operating conditions at the Analysis & Diagnostic Laboratory (ADL) of Argonne National Laboratory. The ADL results provide insight into those factors that limit battery performance and life. The ADL facilities include a test laboratory to conduct battery experimental evaluations under simulated application conditions and a post-test analysis laboratory to determine, in a protected atmosphere if needed, component compositional changes and failure mechanisms. This paper summarizes the performance characterizations and life evaluations conducted during FY 1992 on both single cells and multi-cell modules that encompass six battery technologies [Na/S, Li/FeS, Ni/Metal-Hydride, Ni/Zn, Ni/Cd, Ni/Fe]. These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division, and the Electric Power Research Institute. The ADL provides a common basis for battery performance characterization and lie evaluations with unbiased application of tests and analyses. The results help identify the most promising R&D approaches for overcoming battery limitations, and provide battery users, developers, and program managers with a measure of the progress being made in battery R&D programs, a comparison of battery technologies, and basic data for modeling.

SciTech Connect

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

Battery availability for near-term (1998) electric vehicles  

SciTech Connect

Battery Requirements were determined for a wide spectrum of electric vehicles ranging from 2-passenger sports cars and microvans to full-size vans with a payload of 500 kg. All the vehicles utilize ac, high voltage (340--360 V) powertrains and have acceleration performance (0--80 km/h in less than 15 seconds) expected to be the norm in 1988 electric vehicles. Battery packs were configured for each of the vehicles using families of sealed lead-acid and nickel-cadmium modules which are either presently available in limited quantities or are being developed by battery companies which market a similar battery technology. It was found that the battery families available encompass the Ah cell sizes required for the various vehicles and that they could be packaged in the space available in each vehicle. The acceleration performance and range of the vehicles were calculated using the SIMPLEV simulation program. The results showed that all the vehicles had the required acceleration characteristics and ranges between 80--160 km (50--100 miles) with the ranges using nickel-cadmium batteries being 40--60% greater than those using lead-acid batteries. Significant changes in the design of electric vehicles over the last fifteen years are noted. These changes make the design of the batteries more difficult by increasing the peak power density required from about 60 W/kg to 100--150 W/kg and by reducing the Ah cell size needed from about 150 Ah to 30--70 Ah. Both of these changes in battery specifications increase the difficulty of achieving low $/kWh cost and long cycle life. This true for both lead-acid and nickel-cadmium batteries. 25 refs., 6 figs., 16 tabs.

Battery Capacity Measurement And Analysis  

E-Print Network (OSTI)

In this paper, we look at different battery capacity models that have been introduced in the literatures. These models describe the battery capacity utilization based on how the battery is discharged by the circuits that consume power. In an attempt to validate these models, we characterize a commercially available lithium coin cell battery through careful measurements of the current and the voltage output of the battery under different load profile applied by a micro sensor node. In the result, we show how the capacity of the battery is affected by the different load profile and provide analysis on whether the conventional battery models are applicable in the real world. One of the most significant finding of our work will show that DC/DC converter plays a significant role in determining the battery capacity, and that the true capacity of the battery may only be found by careful measurements.

Battery disconnect sensing circuit for battery charging systems  

SciTech Connect

This patent describes a battery disconnect sensing circuit for battery charging systems which have a pair of cables adapted to be connected to a battery to charge it. The sensing circuit contains a first R-C circuit adapted to connect across the cables and a second R-C circuit adapted to connect across the cables. The time constant of the first R-C circuit is substantially greater than that of the second R-C circuit. Also means connected to the RC circuits produced a momentary control signal in response to disconnection of the cables from a battery being charged. Included in a battery charging system is a source of charging current whose voltage output is controlled at a predetermined value when connected to a battery. It increases to a higher value when disconnected from the battery. Controller means connected with the source activate the battery charging system automatically in response to electrical connection of the battery. The improvement consists of: means for momentarily effecting reversal of the higher voltage value, and battery disconnect sensing means connected the charging source and to the controller means for sensing the reversed higher voltage upon disconnection of the battery charger system from the battery and for responding by automatically deactivating the battery charging system.

Materials and Processing for Lithium-Ion batteries  

Science Conference Proceedings (OSTI)

Lithium ion battery technology is projected to be the leapfrog technology for the electrification of the drivetrain and to provide stationary storage solutions to enable the effective use of renewable energy sources. The technology is already in use for low-power applications such as consumer electronics and power tools. Extensive research and development has enhanced the technology to a stage where it seems very likely that safe and reliable lithium ion batteries will soon be on board hybrid electric and electric vehicles and connected to solar cells and windmills. However, safety of the technology is still a concern, service life is not yet sufficient, and costs are too high. This paper summarizes the state of the art of lithium ion battery technology for nonexperts. It lists materials and processing for batteries and summarizes the costs associated with them. This paper should foster an overall understanding of materials and processing and the need to overcome the remaining barriers for a successful market introduction.

Improving Battery Design with Electro-Thermal Modeling  

DOE Green Energy (OSTI)

Operating temperature greatly affects the performance and life of batteries in electric and hybrid vehicles. Increased attention is necessary to battery thermal management. Electrochemical models and finite element analysis tools are available for predicting the thermal performance of batteries, but each has limitations. In this study we describe an electro-thermal finite element approach that predicts the thermal performance of a cell or module with realistic geometry. To illustrate the process, we simulated the thermal performance of two generations of Panasonic prismatic nickel-metal-hydride modules used in the Toyota Prius. The model showed why the new generation of Panasonic modules had better thermal performance. Thermal images from two battery modules under constant current discharge indicate that the model predicts the experimental trend reasonably well.

Disclosed herein is a venting mechanism for a battery. The venting mechanism includes a battery vent structure which is located on the battery cover and may be integrally formed therewith. The venting mechanism includes an opening extending through the battery cover such that the opening communicates with a plurality of battery cells located within the battery case. The venting mechanism also includes a vent manifold which attaches to the battery vent structure. The vent manifold includes a first opening which communicates with the battery vent structure opening and second and third openings which allow the vent manifold to be connected to two separate conduits. In this manner, a plurality of batteries may be interconnected for venting purposes, thus eliminating the need to provide separate vent lines for each battery. The vent manifold may be attached to the battery vent structure by a spin-welding technique. To facilitate this technique, the vent manifold may be provided with a flange portion which fits into a corresponding groove portion on the battery vent structure. The vent manifold includes an internal chamber which is large enough to completely house a conventional battery flame arrester and overpressure safety valve. In this manner, the vent manifold, when installed, lessens the likelihood of tampering with the flame arrester and safety valve.

In this manner, a plurality of batteries may be interconnected for venting purposes, thus eliminating the need to provide separate vent lines for each battery. The vent manifold may be attached to the battery vent structure by a spin-welding technique. To facilitate this technique, the vent manifold may be provided with a flange portion which fits into a corresponding groove portion on the battery vent structure. The vent manifold includes an internal chamber which is large enough to completely house a conventional battery flame arrester and overpressure safety valve. In this manner, the vent manifold, when installed, lessens the likelihood of tampering with the flame arrester and safety valve.
