NOVELTY - Preparing nickel-doped tungsten disulfide/graphene oxide composite electrode material involves dispersing sodium tungstate dihydrate, thiourea and nickel nitrate hexahydrate uniformly in ethanol solution to obtain suspension. The suspension is subjected to solvothermal reaction and then cooled to obtain the product. The product is subjected to centrifugal washing to get powder, which is collected by freeze drying to obtain nickel-doped tungsten disulfide/graphene oxide composite material. The nickel-doped tungsten disulfide/graphene oxide composite material is calcined and annealed to obtain a nickel-doped tungsten disulfide/graphene oxide composite electrode material. USE - Method for preparing nickel-doped tungsten disulfide/graphene oxide composite electrode material used as a battery negative electrode material (claimed). ADVANTAGE - The method enables to prepare nickel-doped tungsten disulfide/graphene oxide composite electrode material in a simple, cost-effective and controlled manner, has large specific surface area and good flexibility, inhibit the agglomeration of tungsten disulfide nano-sheet, improve the circulation stability of the material, and nickel doping improves the material conductivity, multiplying power performance of the material, so it is applied to the cathode material of the battery, increases the active locating point, has wide research value and application value in the electrochemical field, and used in large scale production.
