摘要
随着市场需求量的增加,高安全性、可靠性成为人们对锂离子电池的基本要求~([1])。为了提高锂离子电池的安全性、可靠性,深入系统的研究电池的失效原因十分重要,包活分析不同化学体系(如LCO-MCMB,LFP-graphite)和不同电池类型(18650圆柱型电池,软包电池,钢壳动力电池)的失效原因。电池的失效机制非常多样,大概可分为如下两类:一类是锂离子电池的材料自身存缺陷而在使用过程中导致衰退,例如正负极的结构衰退,电解液分解,隔膜的老化等;另一类是锂离子电池使用及存储环境引起的衰退,例如环境温度过高,充放电过快,过度充放等~([2])。依托物理所锂离子电池第三方分析、诊断平台,本文从以上两方面介绍锂离子电池失效的不同原因及对应的检测手段,致力于对新鲜电池的性能评估以及老化电池的失效分析。
With the increasing market demands high safety and reliability become people's basic requirements for lithium-ion batteries(LIBs)~([1]).In order to improve the performance of LIBs,it's quite necessary to carry out failure analysis on LIBs,including different chemical systems(such as LCO- MCMB,LFP- graphite) and different cell types(such as 18650 cylindrical battery,soft package batteries and power battery with box-hat).Though the failure causes are very variant,they can be roughly classified into the material related factors,such as structural degradation,electrolyte decomposition and membrane aging,and the operating condition involved factors,such as overheating,overcharging/discharging and charging/discharging at high rate~([2]).In this paper relying on the Comprehensive Analysis Facilities For Energy Storage(Caffes) in Institute of physics,we introduce different failure causes and corresponding detection methods,aiming at the performance evaluation of fresh batteries and failure analysis on aged batteries.
