摘　　要：在众多储能技术中,锂离子电池以其能量密度大、能量转换效率高、循环寿命长、应用范围广、对环境友好等优势,成为当前最具应用前景的电力系统电池储能技术之一。但现有锂离子电池体系无法从本质上保证其安全性,在使用过程中具有发生热失控乃至燃烧、爆炸等安全事故的风险。本文就锂离子电池的热失控机理、电池本体的安全设计、安全预警、电池组热失控起火的阻燃装置以及消防安全的研究进展进行了综述。Among many energy storage technologies,lithium-ion batteries have become one of the most promising energy storage system,due to their high energy density,high energy conversion efficiency,long cycle life,and environmentfriendly features.However,the present battery system cannot guarantee its safety in nature,because of the possible thermal runaway or even safety accident,such as burning or explosion during use.In this paper,the mechanism of thermal runaway of lithium-ion battery,the safety design of battery itself,the safety warning,the fire-retardant device of the thermal runaway battery pack and the research progress of fire safety were reviewed.
