摘　　要：研制了 40Ah混合电动汽车 (HEV)用高功率型锂离子动力电池。放电测试结果显示 :电池大电流输出能力良好 ,最大脉冲功率达 898W /kg。电池循环 2 0 0次 ( 2 5℃ ,1C)的容量保持率大于 90 % ,表现出优异的循环性能 ;电池 -2 0℃与 5 5℃的1C放电容量分别为常温下的 96 63 %和 10 3 % ,具有良好的温度适应能力。安全测试显示40Ah high-power Li-ion batteries were developed. Discharge test showed that it could be discharged with high current and the maximum discharge pulse power of the battery was 898 W/kg. After 200 cycles at 25℃with 1 C rate ,the battery retained 95% of its initial capacity. The discharge capacity at -20℃ and 55℃ retained 96.63% and 103% of its capacity at normal temperature ,it had good adaptability for temperature. Overcharge behavior of the battery was studied and it had strong tole-rance to overcharging.
