摘要: 针对锂离子电池热失控及消防技术,介绍现有不同灭火剂类型,分析其在电池火灾中的灭火机理及优劣势,研究锂离子电池热失控机理及演变过程,对锂离子电池灭火剂的未来进行展望。研究结果表明,这些灭火剂在应对锂离子电池火灾时均满足扑灭明火的基本特性,但仍存在不同程度的复燃风险,灭火时长和阻燃效果也不尽相同;此外部分灭火剂在使用后会对环境和设备产生负面影响。因此,开发兼具高效、环保及防复燃特性的新型灭火剂是未来研究的必然趋势。

Abstract: :Aiming at the thermal runaway of lithium ion battery and fire fighting technology, the existing types of fire extinguishing agents are introduced, their fire extinguishing mechanism and advantages and disadvantages are analyzed, the mechanism and evolution process of thermal runaway of lithium ion battery are studied, and the future of lithium ion battery fire extinguishing agents is prospected.The research results show that these fire extinguishing agents meet the basic characteristics of extinguishing open fire when dealing with lithium-ion battery fires, but there are still different degrees of reignition risk, fire extinguishing time and flame retardant effect are not the same,in addition some fire extinguishing agents will have a negative impact on the environment and equipment after use. Therefore, the development of new fire extinguishing agents with high efficiency,environmental protection and anti-reignition characteristics is an inevitable trend of future research.

Key words: lithium-ion batteries, thermal runaway, fire control technology
