Preparation method of supercapacitor composite electrode material based on foamed nickel

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 invention, the thiourea is usedas a sulfur source, and the precipitant method is simple, convenient and relatively small in pollution. The glutathione is used as a reducing agent, so that the original solid micro beams can be converted into hollow micro beam
