本发明属于超级电容器电极材料制备技术领域，特指一种基于泡沫镍上的超级电容器复合电极材料的制备方法。称取镍盐、硫脲与谷胱甘肽，加入溶剂中，搅拌至分散均匀，并加入基于泡沫镍上的CoO电极材料，于120-200℃下水热8-16h，所得产品水洗、醇洗各三次，烘干后即可得到以泡沫镍为基底的四氧化三钴/硫化镍复合电极材料。本发明中，采用硫脲作为硫源以及沉淀剂方法简便且污染较小。并且利用谷胱甘肽作为还原剂，可使原本实心微米束转变为空心微米束，能够有效地保持电子与离子的传输。通过水热法所得的NiS与CoO结合的更牢固。 The invention belongs to the technical field of preparation of supercapacitor composite electrode materials, and in particular relates to a preparation method of the supercapacitor composite electrodematerial based on foamed nickel. The method comprises the steps of weighing nickel salts, thiourea and glutathione, adding the same into a solvent, and stirring to be uniformly dispersed; further adding Co3O4 electrode material based on the foamed nickel, and heating by water for 8-16h at the temperature of 120-200 DEG C; separately washing acquired products by water and alcohol for three times;and drying to acquire the cobaltosic oxide/nickel sulfide composite electrode material sing the foamed nickel as a substrate. In the preparation method provided by the inv
