摘　　要：由于锂离子电池电压高、循环性能好、比能量高、环境污染少,因此,被广泛应用在各种电子设备中,以及广泛用于电力系统中。在新的电池技术发展过程中,蓄电池的电化学性能和能量密度都有了很大的提高,但同时也会降低其使用寿命,并容易引发电池起火和爆炸。基于此,介绍了过充、锂枝晶、外界撞击和隔膜缺陷等因素对锂离子电池的火灾危害,并结合其成因进行了探讨,给出了相应的消防措施,并提出了今后的研究方向。Lithium ion batteries have been widely used in various electronic devices and power systems due to their high voltage,good cycling performance,high specific energy and less environmental pollution.In the process of new battery technology development,the electrochemical performance and energy density of the battery have been greatly improved,but at the same time,it will also reduce its service life,and easily lead to battery fire and explosion.This paper introduces the fire hazards of overcharge,lithium dendrite,external impact and diaphragm defects on lithium ion batteries,and discusses their causes,and gives corresponding fire protection measures.The future research directions are also proposed.
