摘　　要：由于Ni(OH)_(2)具有成本低、来源丰富、对环境友好及比电容大等优点,常被用作超级电容器的赝电容电极材料。介绍了Ni(OH)_(2)电极材料的一些制备方法,探讨了这些制备方法的优缺点。同时,还对Ni(OH)_(2)及其复合材料(包括Ni(OH)_(2)与其他金属氢氧化物/氧化物、碳材料及导电聚合物等)在赝电容器中的应用进行了综述,并分析讨论了其微观形貌和结构及导电性能等对其电化学性能的影响。Due to its low cost,rich sources,environmental friendliness,and huge specific capacitance,nickel hydroxide has widely been investigated as an electrode material in pseudocapacitance.Herein,we introduced some preparation methods of the Ni(OH)_(2)electrode and analyzed the strength and weakness of these methods.At the same time,the application of Ni(OH)_(2)and its composite electrode materials(including Ni(OH)_(2)/other metal hydroxides/oxides,Ni(OH)_(2)/carbon materials,and Ni(OH)_(2)/conductive polymers)in the supercapacitors were reviewed,and the influence of the morphology,microstructure,and conductivity on the electrochemical performance of the supercapacitor was discussed.
