摘要
法拉第赝电容器兼具二次电池高能量密度和超级电容器高功率密度的优点,而电极材料是决定法拉第赝电容器性能的关键。过渡金属氧化物/氮化物作为两种主要的赝电容器电极材料,能在提高能量密度的同时保持高功率密度。本文综述钌氧化物、镍氧化物、锰氧化物、钒氧化物、钴氧化物、铱氧化物等过渡金属氧化物和钛氮化物、钒氮化物、钼氮化物、铌氮化物等过渡金属氮化物的纳米结构设计和高比表面积复合材料制备的最新进展,为法拉第赝电容器电极材料的深入研究提供重要的借鉴意义。
Faraday pseudocapacitors take both advantages of secondary battery with high energy density and supercapacitors with high power density,and electrode material is the key to determine the performance of Faraday pseudocapacitors.Transition metal oxides and nitrides,as the two main kinds of pseudocapacitor electrode materials,can enhance energy density while maintaining high power capability.Recent advances in designing nanostructured architectures and preparing composites with high specific surface areas based on transition metal oxides and nitrides,including ruthenium oxides,nickel oxides,manganese oxides,vanadium oxides,cobalt oxides,iridium oxides,titanium nitrides,vanadium nitrides,molybdenum nitrides and niobium nitrides,are addressed,which would provide important significances for deep researches on pseudocapacitor electrode materials.
