摘要
循环性能是评价锂离子蓄电池长期正常使用的重要指标。一定的循环周期后将会发生容量的衰减,引起电池安全性能的变化。通过测试锂离子蓄电池循环前后容量、内阻、厚度的变化,对比了循环前后正、负极材料状态的变化,并采用XRD、SEM测试方法进行了研究,总结出锂离子蓄电池的循环性能与安全性能的关系,并从电池热力学角度进行了一定的解释。
Interrelated analysis of cycle and safety characteristics for lithium ion battery was researched. Resistance, capacity and thickness of battery fore-and-aft cycle were tested, state change of cathode and anode was compared. Cathode and anode of lithium ion battery were researched by XRD and SEM, and phenomena was explained from thermodynamics.
