Preparation method of graphene-loaded Ni-Co-S nanorod electrode material

The invention discloses a preparation method of a graphene-loaded Ni-Co-S nanorod electrode material, which specifically comprises the following steps of firstly, taking a graphite foil as an anode and a platinum wire as a cathode, carrying out electrochemical stripping on graphite, mixing the obtained graphene, NiCl2.6H2O, CoCl2.6H2O and urea, carrying out ultrasonic treatment, carrying out hydrothermal treatment, cleaning, drying, mixing with urea and H2O, carrying out ultrasonic treatment, and then carrying out hydrothermal reaction, filtering and drying to obtain the graphene-loaded Ni-Co-S nanorod electrode material. The electrochemical stripping graphene is used as a two-dimensional carrier, the nickel-cobalt sulfide is used as a pseudocapacitance material, the electrode material which is large in contact area, rich in active site and high in conductivity is obtained, in addition, the electrode material is prepared through a two-step hydrothermal method, the electrochemical performance of the electrode
