摘　　要：参照行业标准和IEC标准进行充放电实验,研究环境温度对商品化磷酸铁锂(LiFePO4)动力型锂离子电池性能的影响。从容量和电压平台的角度评价商品化的LiFePO4动力型锂离子电池的循环性能和安全性能。在高温(55℃)条件下,电池着火;在低温(-20℃)条件下,容量衰减严重。Charge-discharge experiments referred to industry standard and IEC standard were taken, the effect of environmental temperature to the performance of commercialization LiFePO4 power Li-ion battery was investigated. The cycle performance and safety performance of LiFePO4 power Li-ion battery were evaluated from the view of capacity and voltage platform. In the condition of high temperature （55 ℃）, the battery was on fire; the capacity decayed in the condition of low temperature （ -20 ℃）.
