2、vivo手机边充电边玩会掉电是为什么？

1.

一边充电一边使用手机,会使通过锂电池的电路密度(current density)相比于非充电状态下使用的手机电池会大大升高。

2.

电路密度的升高会导致锂电池内部电压降增大,电化学能更多地转变为库伦热,热能的产生进一步使锂电池内阻增大,进而继续增大锂电池内阻和产生的库伦热,形成恶性循环。

3.

最终,过电压增大,手机背部设置的安全电压传感器所检测到的锂电池的充放电电压已不是真实充放电电压,结果真实电压会超出规定的安全电压电势窗(potential window)或截止电压(cut-off),导致锂电池电极材料化学结构及成分遭到破坏,材料结构坍塌,导致电池性能急速下降,电量就会越来越少,如果严重的话,会导致充不进电,或者电池鼓包甚至爆炸。
