NOVELTY - A cobalt-iron alloy/graphene composite material manufacturing method involves dispersing oxidized graphene in water, followed by stirring 1,1'-ferrocenecarboxylic acid and cobalt acetate tetrahydrate and dissolving, adding alkali solution to adjust pH, transferring into hydrothermal kettle, heating, cooling, taking out the reaction solution, separating out the precipitate and drying to obtain dried precipitate. The dried precipitate is ground, stirred and calcinated to obtain finished product. USE - Method for manufacturing cobalt-iron alloy/graphene composite material that is utilized as electrode material in super capacitor (claimed). ADVANTAGE - The method enables manufacturing the cobalt-iron alloy/graphene composite material with improved capacitor performance and wide development prospect. DETAILED DESCRIPTION - A cobalt-iron alloy/graphene composite material manufacturing method involves ultrasonically dispersing oxidized graphene in water to obtain graphene oxide dispersion liquid. 1,1'-Ferrocenecarboxylic acid and cobalt acetate tetrahydrate are stirred and dissolved in graphene oxide dispersion liquid at room temperature, the temperature is controlled at 20-80 degrees C, alkali solution to adjust the pH of the solution to 4-12 and stirred for 2-10 hours, followed by transferring into hydrothermal kettle, heating at 40-200 degrees C for 48-72 hours, cooling to room temperature, taking out the reaction solution, separating out the precipitate and drying to obtain dried precipitate. The dried precipitate is ground, stirred under nitrogen atmosphere and calcinated at 400-600 degrees C for 2-8 hours to obtain finished product, where the mass ratio of graphene oxide: water: 1,1'-ferrocenecarboxylic acid: cobalt acetate tetrahydrate is 0.2-0.7 g: 300-400 mL : 1 g: 1-9 g. An INDEPENDENT CLAIM is also included for a cobalt-iron alloy/graphene composite material manufactured by the method.
