▎ 摘  要

NOVELTY - Preparation of graphene negative carbon material comprises taking pitch coke, calcined coke and modified asphalt, adding kneading pot with calcined coke and pitch coke powder, and dry mixing to obtain first mixture; and adding graphene powder to modified asphalt, heating to melt and obtain molten asphalt mixture, adding to kneading pot, kneading to obtain paste, grinding, vacuum packaging, isostatic pressing to obtain carbon strip, baking, graphitizing, and grinding. USE - Method for preparation of graphene negative carbon material. ADVANTAGE - The method saves trouble and labor, and has less steps, low cost, and high production efficiency. The product has greatly improved electrical properties and prolonged service life.
