▎ 摘　　要

NOVELTY - Preparation of graphene current collector involves mixing graphene, binder and solvent at a high speed, and grinding with three rollers or homogeneously mixing to obtain a graphene conductive coating material, scraping or rolling the graphene conductive coating material on the surface of a textured current collector, and drying the graphene conductive coating on the textured current collector in an oven at 50-100degrees Celsius. USE - Preparation of graphene current collector used for lithium-ion battery for mobile phone, camera and small electric tool. ADVANTAGE - The graphene is conductive coating conductive agent which not only increases the conductivity, but also increases the adhesive force, and reduces the dosage of the adhesive agent. The graphene current collector has reduced resistance, and effectively avoids the electrode active substance from falling off the current collector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for preparing graphene current collector. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene current collector.
