Effective Battery Energy Capacity As a Function of Temperature and Discharge Current
Effective Battery Energy Capacity as a Function of Temperature and Discharge Current Michael Ruscito, Mingshi Yang, Tomas Pavydis, Jinghan Huang University of Illinois at Urbana-Champaign PHYS 398DLP, Professor George Gollin 1 May 2020 Abstract The goal of this project is to analyze the effects of variable environmental temperatures and discharge currents on the effective energy capacity of common batteries. AAA batteries with different chemical compositions were considered including: alkaline, nickel-metal hydride, primary lithium, and lithium ion. Additionally, lithium coin cell batteries were tested to compare the results of different form factors. In theory, the chemical reactions and electrical processes within the batteries are optimized to perform at specific temperatures and current draws. These specifications are commonly provided by the manufacturer and give information on the “ideal” conditions for use. Operating outside of these optimal specifications could demonstrate a noticeable effect on battery life expectancy, and more specifically, lower the effective energy capacity. This project’s approach to measure these effects consisted of collecting information on battery voltages under specific temperatures and discharge currents. The results demonstrated that battery behavior is altered by these conditions. I Introduction Nearly all common electronics rely on battery power in order to run and the lifespan of these devices often seems strongly correlated with the temperature around them. For example, a phone battery may appear to drain much quicker during the winter or in colder environments and electric cars seem to lose a noticeable amount of range after being left out in the cold overnight. To combat this, Tesla car batteries will even drain some of their energy in order to heat themselves preventing damage to the energy cells. -
CHARGING AHEAD: How to Find Powerful Rechargeable Batteries That Go on and On…And On
CHARGING AHEAD: How to Find Powerful Rechargeable Batteries That Go On and On…and On A Report by the Responsible Purchasing Network to San Francisco Department of the Environment Recommending Specifications for AA, AAA and D-Sized Rechargeable Batteries for San Francisco’s SF Approved Program Authors: Susan Kinsella Alicia Culver July 2016 The primary purpose of this report, Charging Ahead, is to recommend specifications for three sizes of rechargeable consumer batteries (AA, AAA and D) based on a review of available literature and an assessment of the technical and marketing information about available products. It includes: • Overview and History of Rechargeable Batteries • Recommended Specifications for Rechargeable Batteries that identify the battery chemistry (NiMH), the minimum power rating of the battery (measured in milli-amp- hours) and the maximum self-discharge rate of qualifying products. The specifications, which are based on RPN’s in-depth comparison of NiMH consumer batteries currently on the market, can be met by at least three brands of batteries in each size category. • Best Practices for Procuring and Using Rechargeable Batteries • Glossary of Terms • Comparison of Battery Chemistry Types describes the relative availability as well as the performance advantages and disadvantages of each type of rechargeable battery in the U.S. marketplace and compares them to standard, single-use alkaline batteries. • Applicable Standards • Cost Comparisons of AA NiMH rechargeable batteries with single-use alkaline batteries. • Report References • Appendix A: Benchmarking Assessment, which describes several federal agencies, local governments, state agencies and universities that have evaluated or pilot tested rechargeable batteries for their operations. • Appendix B: Contacts includes people interviewed or communicated with via email during the development of this report. -

Exemption for the Use of Cadmium in Portable Batteries and Accumulators
Exemption for the use of cadmium in portable batteries and accumulators intended for the use in cordless power tools in the context of the Batteries Directive 2006/66/EC Final Report (revised) 26 January 2010 Consortium ESWI Expert TeamBIPRO, to S upportUmweltbundesamt Waste Implementation BiPRO Beratungsgesellschaft für integrierte Problemlösungen ENV.G.4/FRA/2007/0066 iii European Commission ESWI Final Report - Replacement of Cadmium Batteries in Cordless Power Tools ENV.G.4/FRA/2007/0066 iv Executive Summary Background The Batteries Directive 2006/66/EC (repealing Directive 91/157/EEC) entered into force on 26 September 20061. The Directive sets out rules applicable to all batteries and accumulators that are put on the European Union market. These rules include, among others, restriction on the use of cadmium in portable batteries and accumulators (PBA) according to Article 4(1)(b) of the Directive. Portable batteries and accumulators, including those incorporated into appliances, that contain more than 0,002% of cadmium by weight shall not be placed on the market. However, according to Article 4(3) of the Directive the above requirement shall not apply to portable batteries and accumulators intended for use in: (a) emergency and alarm systems, including emergency lighting; (b) medical equipment; or (c) cordless power tools. Furthermore, based on Article 4(4) of the Directive the Commission shall review the exemption from the cadmium ban for use in cordless power tool with a view to the prohibition of cadmium in batteries and accumulators. The Commission shall submit a corresponding report to the European Parliament and to the Council by 26 September 2010, together, if appropriate, with relevant proposals. -
