摘要
MH-Ni蓄电池长期贮存会导致容量下降、极板活性物质钝化、充电接受能力下降,以及电池快速升温等情况。针对电池贮存后容量下降这一现象进行了探讨;结果表明:长期搁置后的蓄电池在使用前进行几次充放电循环,其有效容量和综合性能明显得到提高。
The long term storing of Ni MH battery would lead to fading of cap acity, passivating of plate materials, decreasing of charge acceptance capabilit y and rising of temperature at final stage of charge.The phenomenon and cause of capacity fading after long term storing of battery were introduced in this pap er.The experimental results showed that,before practical application, the initia l capacity and comprehensive performance of stored battery can be obviously incr eased after some charge-discharge cycles.
