摘要
为满足锂离子蓄电池大于15年的长寿命使用需求,对锂离子蓄电池在不同存储条件下的性能进行探索。设计了不同温度、不同荷电态对锂离子蓄电池进行储存实验,通过交流阻抗、直流动态阻抗、电性能测试及安全性测试,总结电池在长期储存过程中以及循环使用过程中电池的阻抗特性、安全性变化规律,为较全面、系统地评估电池的性能和状态、进行技术分析打下基础。
To meet long-life（longer than 15 years） requirements of lithium-ion battery, extensive tests had been conducted on lithium-ion battery in order to find the optimistic storage conditions. Lithium ion batteries were stored at different temperature and different state of charge（SOC）. The performance of batteries was acquired by means of AC-impedance, DC-impedance, cycle ability, rate ability and safety tests.
