摘　　要：空天往返飞行器舵机等负载会对满荷电态锂离子电池组产生较大的高频正负脉冲电流,正负脉冲电流可能导致锂离子电池性能衰退和发生短路危害。针对空天往返飞行器的使用环境和要求,研制了ITP20锂离子电池单体,并进行高低温度下正负脉冲电流循环测试,循环实验后进行了电性能测试评估及破坏性物理分析(DPA),结果表明,一定时间范围下大的正负脉冲电流对锂离子电池性能无明显影响,无安全性问题。Reentry aerocraft steering engine brings large charge or discharge high frequency pluse current into full charged Li-ion battery,large charge or discharge pluse current possibly results in performance decline,taking place short circuit safety accidents.According to reentry aerocraft condition and requirements,developing ITP20 cell,high/low temperature large charge or discharge pluse current cycles of ITP20 cell was tested,and electrical performance test evaluation and destructive physical analysis(DPA)were carried out after the cyclic experiment.The results show that large charge or discharge pluse curren has little effect on Li-ion battery performances.
