摘要 分析了影响锂离子电池安全性的主要因素和关键材料。通过钴酸锂(LiCoO2)表面包覆和使用电解液阻燃添加剂,研制了具有较好耐过充安全性的原型LiCoO2正极锂离子电池。该电池经1C、20 V过充电,没有燃烧的现象。 The main factors and key materials responsible for Li-ion battery safety were analyzed. The overcharge safety lithium cobalt oxide(LiCoO2) cathode prototype Li-ion battery was developed based on surface coating LiCoO2 and using fire resistant electrolyte additives. The battery did not fire while overcharged with 1 C,20 V.
