摘要: 本文阐述了锂离子电池常规安全性问题和热失控引发燃烧爆炸泄漏毒物的非常规安全性问题,探讨了锂离子电池泄露物的毒性及其对人体和环境的危害,以电动车用锂离子电池为例分析了城市交通和环境将面临的继发问题和压力,定量对比了10 A·h软包装的磷酸铁锂、锰酸锂和三元材料锂离子电池热失控燃烧释放的代表性毒物之一的CO浓度,提出了锂离子电池热失控毒物安全性问题的不可回避性。

关键词: 锂离子电池, 材料, 毒物, 热失控

Abstract: The safety and thermal runaway processes of a lithium ion battery and its toxic leakage effects on human and environments are elaborated and discussed in detail. The EV power lithium ion battery was used as example to analysis its impact to a city environment. One of the representative combustion toxics CO was analyst in quantity from three different 10 A·h lithium ion cell (LiFePO4, LiMnO2 and NMC) combustion experiment. It shows that the toxics safety problems of lithium ion battery can not be ignored any more.

Key words: Li-ion battery, materials, toxics, thermal runway
