摘　　要：锂电池储能系统火灾具有热失控温升快、热蔓延速度快、易复燃、燃烧特性复杂等特点,因此限制了其大规模应用。为解决这一问题,概述了锂电池热失控起火机理,对比分析了各类灭火剂对锂电池火灾的抑制效果,指出了现有锂电池灭火试验研究存在试验尺度小、系统布置缺乏标准等问题,并提出了开发兼具高效灭火与快速冷却功能的新型灭火剂、统一锂电池灭火剂的试验尺度及评价标准等建议,为锂电池消防技术的发展提供理论和技术支撑。The fire of lithium battery energy storage system has the characteristics of fast thermal runaway temperature rise,fast thermal spread,easy reburning and complex combustion peculiarity,which limits its large-scale application.To address this situation,the mechanism of lithium battery thermal runaway fire was outlined,the suppression effect of various types of extinguishing agents on lithium battery fire was compared.The problems of small test scale and lack of standards for system arrangement in the existing lithium battery fire extinguishing test research were pointed out,and suggestions such as developing new extinguishing agents with efficient fire extinguishing and fast cooling functions,unifying the test scale and evaluation standards of lithium battery extinguishing agents were put forward,providing theoretical and technical support for the development of lithium bat-tery fire technology.
