摘要(Abstract):

外部短路是锂离子电池应用中的主要失效模式之一。外部短路会导致锂离子电池在较短的时间内产生较大的短路电流,带来热失控风险。当前锂离子电池外部短路的研究主要集中在小容量的电池上,但是不同容量的电池会在短路持续时间、短路温升以及温升滞后等行为上产生明显的差异。本文以51 Ah三元(NCM622)商用方形锂离子电池为研究对象,探究了锂离子电池在不同电阻下的短路行为,并关注了温度特征。研究表明,锂离子电池短路放电容量、短路电流对最高温度具有决定作用。高容量方形锂离子电池产热速率与导热速率的不平衡导致锂离子电池短路过程温升的滞后性。对短路后的电池进行拆解,电池内部发生了正极对隔膜的热粘接以及正极析铜现象,外部短路对锂离子电池产生了不可逆的破坏。基于锂离子电池在短路过程中电压、电流、温度的变化,提出锂离子电池短路机制。
