锂离子电池针刺测试影响因素研究

Study on the influence factors of acupuncture test for Li-ion battery

对锂离子电池进行针刺测试时,电池很容易发生内部短路,进而发生爆炸起火等危险。为了提高电池的稳定性,本文从隔膜、电解液阻燃添加剂、导电剂黏结剂和电池结构四个方面综述了有关电池针刺测试的影响因素,并提出了合理化建议,这对提高电池的安全性能,促进电池产业发展有很大的帮助。

When testing with acupuncture, it is prone to have short-circuited the battery, and then experiences explosion and fire. In order to improve the stability of battery, this paper describes the influence factors of acupuncture test for battery from four aspects, such as separator, electrolyte flame-retardant additives, conductive agent, binder and structure. Besides, we also propose proper suggestions. It has great help to improve the safety and to promote the development of battery industry.
