摘　　要：锂离子电池因其能量密度高、自放电率低、循环寿命长、输出功率大等优点被广泛应用于储能领域,然而由于其不稳定性导致储能事故频发。从热失控-火灾蔓延角度出发,对热失控机理进行探究,基于产气成分及含量、膨胀力、表面温度、电压变化等热失控特征参数,对现有的磷酸铁锂体系电池早期预警(外部)方式进行综述,在此基础上,提出未来电池热失控早期预警(外置)的发展思路,为锂电池热失控早期监控及预警提供思路。Lithium ion battery is widely used in energy storage field because of its advantages of high energy density,low self dis-charge rate,long cycle life and large output power.However,due to its intrinsic instability,more and more accidents occur fre-quently in energy storage.From the point of view of thermal run-away and fire propagation,this paper explores the mechanism of thermal runaway.Based on the characteristics of thermal runaway such as gas generation composition and content,expansion force,surface temperature and voltage-drop,the existing early warning(external)methods are summarized.On this basis,the develop-ment idea of early warning(external)of battery thermal runaway in the future is proposed,which provides ideas for early monitor-ing and early warning of thermal runaway of lithium battery.
