碱性锌电池负极材料的研究进展

Research on anode material of alkaline zinc battery

基于锌的碱性电池例如锌镍电池、锌银电池等因锌资源丰富、比容量高而被广泛关注。但锌负极普遍存在变形、枝晶、自腐蚀、钝化等问题,降低了电极的循环寿命,影响了锌镍等电池的产业化发展。围绕解决锌负极缺陷的方法,从添加剂、材料表面改性、材料结构设计及电解液改性等方面将近年来的研究成果总结分析。

Zinc based alkaline batteries,such as nickel zinc batteries and silver zinc batteries,have attracted much attention due to their rich zinc resources and high specific capacity.However,the problems of deformation,dendrite,self corrosion and passivation exist in zinc negative electrode,which reduce the cycle life of the electrode and affect the industrial development of zinc nickel batteries.The research results in recent years were summarized and analyzed from the aspects of additives,material surface modification,material structure design and electrolyte modification.
