摘要
综述了锂离子电池正极活性材料、充电制度、热稳定性及过充保护添加剂等对锂离子电池过充电行为的影响,指出:优化正极材料的热稳定性、采用合理的充放电制度可防止因电池过充时温度过高而造成安全隐患;选择合理的过充保护添加剂是提高锂离子电池耐过充性能的主要措施.
The effect of overcharge performance of Lithiun ion battery was summarized by suming up the affecting factors such as active materials of cathode, charge regime, additives of overcharge protection, thermal stability etc, of the overcharging tolerance of the batteries. It is pointed out that prevent the safety hazard through optimizing hot stability of the anodal material and rational The main measures of improving overcharge performance was adaptive system of charging and discharging. overcharge protecting additive.
