摘要
Abstract
Over-discharge behavior of power battery modules was investigated using prismatic aluminum shell lithium iron phosphate(LiFePO4) cathode Li-ion battery.Failure state of power battery modules was reproduced by over-discharge test of single battery/battery modules and cyclic voltammetry of button cell.Capacity fading was accelerated by over-discharge when the voltage of battery over 0.This fading could be result in capacity unbalance among battery module during usage.The lower capacity battery would be discharge to the voltage under 0 at normal voltage range of battery module.It made the battery failure.关键词
