▎ 摘　　要

NOVELTY - The device comprises an electrolytic cell (1), a clamp (2), an electrode material (3) and a conductive plate (4). The inner portion of the electrolysis cell is provided with a clamp. The clamp is arranged inside the electrolytic tank. The conductive plate is provided inside the clamp. An electrode material is provided on the conductive plate. The electrode material is extended into the electrolytic tank, and both sides of the conductivity plate are connected to a variable frequency power supply. The conductive plate is platinum sheet or copper plate. USE - Device for mass production of graphene material such as carbon material graphene by electrochemical method, used in industrial application. ADVANTAGE - The high-quality water-based graphene dispersion or slurry can be obtained after separation, washing and dispersion from the electrolyte. High-quality few-layer graphene powder can be obtained by freeze-drying or spray-drying. The separated electrolyte and cleaning water can be reused as electrolyte after concentration adjustment, which is a green and environmentally friendly graphite material production process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production method for mass production of graphene material by electrochemical method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structure of the device for mass production graphene material by electrochemical method. 1Electrolytic tank 2Clamp 3Electrode material 4Conductive plate
