摘要
安全问题已成为制约锂离子电池向大型化、高能化方向发展的主要障碍。文章概述了从电池自身系统的影响及正极材料对电池的影响两个角度,来分析锂离子电池的安全问题的原因,并对三元正极材料残留锂对电池性能的影响进行分析,提出通过控制残留锂含量来在保障产品电性能的同时控制安全性能。
Safety issues have been the main obstacle to restrict lithium ion batteries to large scale and high energy density. The article summarizes the causes of lithium-ion battery safety issues from two aspects, namely, battery-system and cathode materials. The influence of residual lithium in Li NixCoyMn（1-x-y）O2 on battery safety is analyzed in this article. It is also proposed that not only the electrochemical performance but also the safety performance can be improved by controlling the residual lithium content of Li NixCoyMn（1-x-y）O2.
