硫化镍电极材料的制备及其电化学性能研究

Preparation and Electrochemical Properties of Nickel Sulfide Supercapacitor Electrode Material

电极材料是影响超级电容器性能的关键所在,目前已发现氧化镍作为超级电容器电极材料具有良好的电容性能,利用硫元素与氧元素同族的特点,研究硫化镍的电容性能。以碳布为基底,将六水合硝酸镍和六次甲基四胺混合溶液通过水热法制备氧化镍;然后利用硫代乙酰胺溶液水热硫化得到硫化镍,并通过循环伏安法、热场扫描电子显微镜、拉曼光谱分析法、X射线粉末晶体衍射等方法表征所制备硫化镍的电化学性能和形貌组成。

Electrode materials is a key influence supercapacitors, nickel oxide has been found as a supercapacitorelectrode materials witli good capacitive behavior, because of elemental sulfur and oxygen characteristics of thesame family, research capacitive properties of nickel sulfide. Nickel oxide was prepared by hydrothermal method using a mixture of nickel nitrate hexahydrate （ Ni （ NO3 ）3 · 6H2O） and hexamethylenetetramine （ HMT） using flexible carbon cloth as substrate. Then nickel sulfide was obtained by hydrothermal treatment with thioacetamidesolution. Cyclic voltammetry （ CV）, thermal field scanning electron microscopy （ SEM）, Raman spectroscopy, X-ray powder diffraction （ XRD） were conducted on the as-prepared sample.
