摘要
随着电动车、新能源汽车的广泛使用,其安全问题日益凸显,特别是锂电池的安全性成为研究的重点。本文综述了过充、锂枝晶、外界撞击及隔膜缺陷等对锂电池火灾事故的影响,通过锂电池火灾事故的原因分析,提出锂电池火灾灭火对策。最后对锂电池的保护机制进行了展望。
With the wide use of electric vehicles and new energy vehicles,its security problem is increasingly prominent,especially the safety of lithium-ion batteries is the focus of research in recent years.The cause of short circuit like overcharge,lithium dendrite,diaphragm defects,outside impact were analyzed,through Research on factors of the fire accident on Lithium-ion battery,fire extinguishing measures of lithium-ion batteries were put forward.Finally,lithium battery protection mechanism was discussed.
