Challenges and Mitigation of Li-ion Battery Performance at Low Temperatures for Military Applications

Abstract

Lithium ion batteries are used for enormous application across the globe. Its being widely used in armies also. The use of lithium batteries at low temperature has poor performance, whether charging or discharging, and may have an impact on life. Under low temperature conditions, the performance of lithium battery will decline, such as prolonged charging time, reduced charge and discharge, smaller battery capacity and faster power loss, which will affect the driving mileage of new energy vehicles. Low temperature conditions significantly reduces the battery power hence it is crucial to understand the various factors responsible for degradation of LIBs at various temperatures. For example a fully charged laptop in one place , if brought to a high altitude place immediately shows 10% charge just reaching there. In this paper the generic effects of both high and low temperatures on LIBs are covered and more focus will be on improving the performance of batteries in extreme cold climates. Low temperature LIBs are designed to operate in harsh environments where the temperature is below 0°C
