Performance Loss of Lithium Ion Polymer Batteries Subjected to Overcharge and Overdischarge Abuse

Abstract

Lithium-ion-polymer (LiPo) batteries are rechargeable energy storage devices which power a variety of unmanned ground and aerial vehicles throughout the Department of Defense. Thin form factor make LiPo cells ideal for assembling in large strands or stacks to make high voltage and high energy batteries. However, faulty connections between cells or improper cell balancing during routine charge/discharge can lead to overcharge or overdischarge of an individual cell, thus reducing performance and safety. This report presents the performance loss of commercial LiPo cells subjected to repeated overcharge and overdischarge abuse.
