锂离子电池容量损失原因分析

On capacity fading and its mechanisms for lithium-ion batteries

二次锂离子电池在充放电过程中，由于过充电或过放电、电解液氧化分解、钝化膜的形成、活性物质的溶解及其他现象会导致电池容量损失，综述了锂离子电池容量损失的原因并对其反应机理作简要阐述。

The capacity of lithium-ion secondary batteries was decreased during cycling. The capacity loss or fading occurred due to several different reasons, which were including overcharge or overdischarge, electrolyte decomposition, passive film formation, active material dissolution. The current literature about capacity fading source and mechanism of lithium ion batteries was reviewed.
