摘要
超级电容器(supercapacitor,SC)是近年出现的高功率、高能量密度和长循环寿命的新型储能装置,利用表面双电层储能或在材料表面及近表面与特定离子发生快速可逆的法拉第反应储能。镍钴硫化物电极材料具有比单一硫化物和相应氧化物更高的导电性,同时两种金属离子的协同作用使其具有优异的电化学性能。结合近年相关文献报导,综述了镍钴硫化物电极材料的工作原理、制备方法、电化学性能及其优缺点,展望了其在储能机理和结构设计上的研究前景。
Using electric double layers or rapidly reversible Faraday＇s reactions with special ion on or near the surface, supercapacitor （SC） is a new energy storage device of high power/energy density and long cycle life in recent years. The study of nickel-cobalt sulfide electrode material has been gotten more attentions, because of their higher electrical conductivity than single sulfides or oxides, and excellent electrochemical performance resulted by synergy effects of two metal ions. According to the related literatures reported in recent years, working principles, preparation methods, electrochemical performance and merits/demerits of nickel-cobalt sulfide are reviewed, and researches of its storage mechanism and structure design are prospected.
