摘　　要：锂离子电池贮存性能近来越来越得到重视。考察了不同充电状态、不同贮存温度的LiFePO4锂离子电池的剩余容量、恢复容量、内阻、充放电平台以及充放电循环寿命。结果表明:在磷酸亚铁锂电池使用时,80%荷电状态的电池贮存性能好于100%荷电状态的电池,而且从安全性考虑,满电态贮存的电池危险性也很大。The storage performance of Li ion batteries gets more attention recently. The residual capacity, recovery capacity, internal resistance, charge discharge platform and cycle life of LiFe- PO4 Li-ion battery at different charge states and different storage temperatures was examined in this paper. The results showed that, in the use of the batteries,the storage performance of LiFe PO4 Li-ion battery with 80% state of charge was better than that of LiFePO4 I.i ion battery with 100% state of charge, and it is also very danger that batteries are stored at fully charged state.
