| description | The invention discloses a method for electrochemical preparation of graphene. The method comprises the following steps of: (1) heating and melting alkyl acid, then adding crystalline flake graphite, mixing the substances uniformly, and carrying out compression molding to obtain a graphite electrode; (2) taking a graphite electrode as an anode, immersing the graphite electrode into an electrolyte solution, and applying a direct-current voltage for electrochemical expansion to prepare expanded graphite; and (3) carrying out liquid-phase ultrasonic stripping on the expanded graphite to obtain a graphene slurry, and drying the graphene slurry to obtain the graphene powder. The invention provides the new method for electrochemical continuous preparation of graphene, and solves the technical problems of complex preparation process, higher cost, unsuitability for large-scale production and easy environmental pollution in the existing graphene preparation technology.
