| 摘 要： | 采用低成本的两步水热法直接将Co-Al双金属硫化物生长在泡沫镍上,成功制备了CoAl2S4/Ni电极材料,利用X射线衍射(XRD)、扫描电镜(SEM)和电化学测试等手段对其结构、形貌和超级电容性能进行了表征。结果表明,CoAl2S4/Ni电极材料呈现花瓣状的三维多孔结构,且表面粗糙,这种结构有利于电解液和电极材料的充分接触,具有良好的导电性和比电容性能；当电流密度为1A/g时,电极的放电比容量高达2187.1 F/g, 循环100次后比电容的保持率为90.1%,相关研究为超级电容器电极材料的制备及性能研究提供思路。

| Abstract: | The binary Ni-Al sulfide with petal-like structure was grown directly on Ni foams via a low cost two-step hydrothermal method. The CoAl2S4/Ni electrode materials were successfully prepared. The structure and surface morphology were characterized by X-ray diffraction analysis, field emission scanning electron microscopy (FESEM), respectively. The results show that the CoAl2S4/Ni electrode materials own amorphous porous structure and rough surface with high conductivity, capacitance and transport rate for electrolyte ions and electrons. The specific capacitance of the electrode can reach 2187.1 F/g under current density of 1A g-1. It displayed good electrochemical stability with 96.28% of the initial capacitance over consecutive 100 cycles. The researches are expected to provide a reference for the fabrication of supercapacitor electrode materials and its properties of electrochemistry.
