Abstract: The research progress of carbon-coated metal oxides as electrode materials for supercapacitor is reviewed. The application status and problems of precious metal oxides (such as RuO2) and cheap metal oxides (such as of Fe3O4,SnO2,TiO2,MnO2,etc.) as electrode materials for supercapacitor are presented. Core/shell structure formed by carbon-coated cheap metal oxide resolves the problems of dissolution of metal oxide in the electrolyte,and expansion of charge and discharge volume,and proposed its application prospect in consumer electronics,aerospace and national defense technology as electrode materials for supercapacitor.

Key words: supercapacitor, metal oxide, carbon-coated, electrode material

摘要: 综述了碳包覆金属氧化物作为超级电容器电极材料的最新研究进展。详细介绍了贵重金属氧化物(如RuO2)和廉价金属氧化物(如Fe3O4、SnO2、TiO2、MnO2等)在超级电容器电极材料领域内的应用现状和存在的问题,指出了碳包覆廉价金属氧化物所形成的核/壳结构很好地解决了金属氧化物易溶于电解液、充放电体积易膨胀等问题,展望了其作为超级电容器电极材料在消费电子、航空航天、国防科技等领域中的应用前景。
