▎ 摘　　要

NOVELTY - The method involves using graphite foil as a carbon electrode, that is, an anode. A platinum wire is used as a cathode. The graphene, nickel chloride hydroxide, cobalt chloride hydroxide and urea are mixed. Ultrasonic treatment is carried out and transferred to an autoclave for hydrothermal treatment to obtain a hydrothermal product; Finally, the hydrothermal product is vacuum filtered and washed with deionized water for several times to obtain a graphene-nickel-cobalt oxide precursor. The graphene-nickel-cobalt oxide precursor is put into an oven to dry to obtain graphene-nickel-cobalt oxide precursor powder. The graphene-nickel-cobalt oxide precursor powder, thiourea and water are mixed and ultrasonically treated and transferred into the autoclave and carry out hydrothermal reaction, The hydrothermal product is then vacuum filtered, washed with deionized water for several times, and dried to obtain the graphene-supported nickel-cobalt-sulfur nanorod electrode material. USE - Preparation method of graphene-loaded nickel-cobalt-sulfur nano-rod electrode material used in electrochemical performance of energy storage device such as super capacitor and lithium ion battery (LIB). ADVANTAGE - The method is configured to provide the electrode material with large area contact rich active site, high conductivity, and improved electrochemical performance and energy density. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of the graphene-nickel cobalt sulfide sample.
