Effect of fast charging on the performance of lithium-ion battery 问题 具体因素 对电池造成的影响 负极界面析锂 快速充电过程，由于电流倍率较高，导致负极极化过大，进一步产生较高的过电位，为金属Li的沉积提供了条件，使得负极表面析锂长期充放电循环，进一步产生锂枝晶，可能刺破隔膜导致内短路，发生燃烧 锂枝晶导致电池安全性产生隐患 正、负极材料 结构 Li+在正、负极材料内部的快速脱出和嵌入，对材料颗粒内部的结构及稳定性有较大的影响，导致材料结构容易塌陷 电池循环性能下降 电解液 快速充放电过程电流较大，导致电池阻抗较大的部位产生较高的温升，高温会使得电解液部分成分发生分解，导致电解液性能下降 电池电性能和循环性能衰减严重
