摘　　要：叙述了二次锂离子电池过充保护添加剂的原理、特点,介绍了金属茂化合物、聚吡啶络合物、二甲羟基苯衍生物等氧化还原对添加剂和联苯、二甲苯、环己苯等电聚合添加剂的研究现状,并对过充保护添加剂的前景进行了预测,认为电聚合添加剂、氧化还原添加剂和其他保护装置的联合使用将是今后发展的方向。In this paper,the principle and characteristics of overcharge protection additives for lithium ion sec ondary batteries are described. Developments of redox shuttle additives including metallocenes, metal complexes with phenanthroline,dimethoxybenzene derivatives and elctropolymerization additives including biphenyl, xylene, cyclohexyl benzene are introduced. And the prospect of overcharge protection additives is predicted. The application of elctropolymerization additives,redox shuttle additives associated with other protection devices is regarded as the development direction in the future.
