1 伴随组分的转变，达到高氧化状态。组分的转变容易引起相转移和物理相结构的变化。所以电极材料相变是由于晶格参数的变化以及晶格失配，进而引起晶粒开裂而产生的感应应力，并且导致开裂不断扩展，造成材料的结构破坏，造成电化学性能的衰减，也导致了我们电池容量的衰减。

2、洗电池负极材料的结构；锂离子电池容量的衰减首先发生在这个阶段，此阶段形成于负极表面消耗部分锂离子。随着锂离子电池的使用，石墨结构的改变也会造成电池容量的下降，所以锂离子电池的容量衰减也会引起。 3、电池正极延长反应：当正极活性物质含量过低时，容易引起正极超声充电不良。

洗骑行电池正极过渡造成容量损失是由于电化学惰性物质（如CO3O4、MN2O3等）的出现，破坏了电极间的容量平衡，造成容量衰减。
