摘要:

锂离子电池自问世以来,凭借其能量密度高、循环寿命长等优点,已经被广泛应用于人们生活的各个方面。然而锂离子电池本身有着不可忽视的安全问题,锂离子电池因热失控引发的火灾、爆炸等事故造成了不可避免的财产损失和人员伤亡,锂离子电池的安全问题也越来越受到人们关注。本文结合了热失控的相关知识,分析了电池出现热失控时出现的温度、内阻、电压、电池内部压力及生成的气体等特征参数,从这些特征参数着手对现有的锂离子电池热失控进行安全预警方法进行了总结并对未来的电池预警发展趋势做了分析与展望。

Abstract:

Since its invention, the lithium-ion battery has been widely used in various aspects of human life due to its advantages of high-energy density and long cycle life, among others. However, the safety problem of the lithium-ion battery cannot be ignored. Accidents, such as fire hazards and explosions caused by the thermal runaway of a lithium-ion battery cause inevitable property loss and casualties. Hence, many researchers have been paying attention to the safety problems of the lithium-ion battery. This study analyzes existing early warming methods of the lithium-ion battery thermal runaway from characteristic parameters like temperature, resistance, voltage, and inside pressure and the produced gas of the batteries combined with the knowledge of thermal runaway, concludes the normal early warning methods, and performs analyzation and prospect of the development of future early battery warming methods.

Key words: lithium-ion battery, warning methods, characteristic parameters, temperature, characteristic gas
