In this thesis , the research and development status of nickel metal hydride batteries have been reviewed . based on the result mentioned above , the effects of ptfe content , cut - off voltage and charge time at activation , the different concentration of koh or lioh or xaoh in alkaline electrolyte on the key characteristics are studied 本文先对镍氢电池各工作部分的研究情况进行了综述，并在此基础上，研究了ptfe乳液用量，化成时截止电压以及充电时间，碱液中改变koh 、 lioh 、 naoh浓度对电池各项性能的影响。
The charging is unable to accomplished if the battery is damaged or removed and ic will always stay at the charging status , fortunately , due to the charging period of the li battery with certain capacity is assessable , a timer can be added to disable charging if the maximum charging period is exceed 充电时间保护:锂电池被损坏或被移除时,充电不能完成,芯片会被一直设定在充电状态。而一定容量锂电池的充电时间是可以预计的,因此可以设计一个定时器,在锂电池超出最大充电时间时,停止对它的充电。
