Publication number: 20220052393Abstract: Lithium ion batteries and battery modules are disclosed. The lithium ion battery includes a housing where a positive electrode, a negative electrode, and an electrolyte are provided. Some of the areas of the housing are made from the fusible material. When the temperature in the housing exceeds a set threshold, the area, made from the fusible material, on the housing is communicated, where the electrolyte flows out to separate from the positive electrode and the negative electrode. Timely separation of the electrolyte in the single lithium ion battery is achieved when the temperature thereof rises abnormally, the electrolyte is effectively protected from being ignited or decomposed, the single lithium ion battery is protected from being ignited and exploded, and damages to the rest surrounding single lithium ion batteries caused by a chain reaction brought by the single lithium ion battery of which the temperature rises abnormally are avoided.Type: ApplicationFiled: May 29, 2019Publication date: February 17, 2022Applicants: State Grid Jiangsu Electric Power Research Institute, Jiangsu Electric Power Research Institute Co., Ltd.Inventors: Hongbin ZHU, Xiaoqin ZHANG, Xiang YU
