▎ 摘　　要

NOVELTY - Electrochemically preparing grapheme involves heating and melting the alkyl acid, adding flake graphite, mixing uniformly and pressing to form a graphite electrode, and then immersing the graphite electrode as an anode in the electrolyte and applying direct current voltage to perform electrochemical expansion to obtain expanded graphite. The graphene slurry is prepared by performing liquid phase ultrasonic peeling on the expanded graphite, and then the graphene slurry is dried to obtain graphene powder. USE - Method for electrochemically preparing graphene. ADVANTAGE - The method enables to continuously prepare graphene, and reduces the technical problems in the existing graphene preparation technology, and production cost and not pollutes environment.
