摘　　要：LiFePO4电池以其卓越的安全性和良好的综合电化学性能成为目前众多锂电池公司与EV/HEV制造公司关注的重点,然而由于LiFePO4电池在材料及工艺等方面还存在一些问题,使得LiFePO4电池在配组使用的时候,电池的一致性和其性能会随着使用时间推移有一定程度的下降。介绍了一种专门用于LiFePO4电池的电解液添加剂-氧化还原飞梭的基本性能和作用原理,为LiFePO4电池在EV/HEV中的大规模商业应用提供了一个现实的解决方案。LiFePO4 lithium ion battery is the most popular and suitable battery for HEV/EV due to its excellent safety and integrated electrochemical performance. But LiFePO4 battery has some problems in material and process, which result in the decrease of consistency and performance with the time when the batteries are used in matching. The basic performance and theory of a novel electrolyte additive for LiFePO4 battery was introduced in this paper which will provide a solution for the wide application of LiFePO4 lithium ion battery in EV/HEV.
