摘要/Abstract

摘要： 应用溶剂热法合成Ni3S4微米球，采用XRD和SEM表征样品物相结构、观察其微观形貌. 电化学性能测试表明Ni3S4电极有较好的比电容性能，0.5和4 A?g-1放电电流密度下，其比容量分别为1120.6和433.4 F?g-1. 1000周循环充放电后，其容量保持率为89.37 %和84.88 %. 通过XRD、XPS和CV测试，结果表明其电化学反应机理为Ni(OH)2与NiOOH的相互转化.

Abstract: The Ni₃S₄ microspheres have been synthesized via a facile solvothermal method. The crystal structure and surface morphology are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Microspherical Ni3S4 exhibits good electrochemical capacitance validated by electrochemical measurements. The specific capacities of 1120.6 F.g-1 at 0.5 A.g^-1 and 433.4 F.g^-1 at 4 A.g^-1 with the capacitance retention of 89.37 % and 84.88 % were obtained after 1000 cycles, respectively. The electrochemical reaction is expected due to the transformation of Ni(OH)₂ and NiOOH based on the XRD, XPS and CV analysis results.

Key words: supercapacitor, nickel sulfide, solvothermal method
