DETAILED DESCRIPTION - Preparing graphene intercalation material involves weighing certain amount of natural graphite to prepare graphite solvent through chemical reagents and oxidizing agents to perform redox reactions, adding vanadium oxide to graphite solvent multiple times and stirring and mixing thoroughly to prepare graphite oxide mixture, placing obtained graphite oxide mixture into mixer for heating, and stirring and drying to obtain a solid reactant. The fixed body reactant is washed with water, and washed solid is dried at a low temperature to obtain graphite oxide powder. The high-temperature heating and peeling of graphite oxide powder is performed to obtain graphene oxide. The graphite oxide is placed into water and mixed, and dispersed by ultrasonic vibration to form uniformly dispersed graphene oxide solution. An ammonia water is added drop-wise to graphene oxide solution to form mixed aqueous solution by dissolving reducing agent in water. The prepared graphene oxide solution and reducing agent aqueous solution are mixed uniformly, resulting mixed solution is placed under oil bath conditions, and stirred. The mixture is filtered, washed, and dried after the reaction is completed to obtain graphene.
