NOVELTY - Preparing graphene/graphene nano belt/nickel disulfide composite aerogel comprises (i) preparing graphene oxide nano belt, (ii) preparing graphene oxide, (iii) mixing 0.1 g graphene oxide nano belt obtained in the step (i), 0.1 g graphene oxide obtained in the step (ii), and 1 g hexadecyl trimethyl ammonium bromide, then adding 100 ml deionized water, and ultrasonically treating to obtain mixed solution, (iv) adding 0.6 g thiophene, 50 ml n-octane and 0.4 g nickel nitrate to the mixture obtained in the step (iii), hydrothermally reacting at 165-180 degrees C for 4-6 hours to obtain hydrogel, (v) placing the hydrogel obtained in the step (iv) into a potassium nitrate solution, performing secondary hydrothermal reaction at 120-130 degrees C for 2-3 hours, cooling to room temperature, filtering, washing and freeze-drying, and (vi) thermally cracking the product obtained after freeze drying in the step (v) in an argon atmosphere to obtain the product. USE - The graphene/graphene nano belt/nickel disulfide composite aerogel is useful in electrode materials for supercapacitors. ADVANTAGE - The method: improves the electrochemical performance of the graphene/graphene nano belt/nickel disulfide composite aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for using the graphene/graphene nano belt/nickel disulfide composite aerogel, comprising adding graphene/graphene nano belt/nickel disulfide composite aerogel, acetylene black, and polytetrafluoroethylene emulsion into the same weighing bottle in a mass ratio of 90:5:5, stirring and mixing uniformly, blowing the sample to a paste with an electric blower, using nickel foam as the current collector, coating the paste material on nickel foam, and vacuum-drying at 120 degrees C for 24 hours to obtain the required electrode.
