▎ 摘　　要

NOVELTY - Preparation of activated carbon composite graphene foam electrode sheet involves adding oxidized graphene and polyacrylonitrile to a ball mill, ball-milling, adding mixed solution of ethanol and water, ultrasonically processing, forming a oxidized graphite suspension, adding foam nickel, evaporating solvent, providing in a muffle furnace, reacting, immersing in hydrochloric acid, reacting, obtaining graphene foam, adding activated carbon to anhydrous ethanol, ultrasonically processing, coating resultant activated carbon ethanol suspension on the graphene foam, drying, and cooling. USE - Preparation of activated carbon composite graphene foam electrode sheet (claimed). ADVANTAGE - The method enables economical preparation of activated carbon composite graphene foam electrode sheet without adding binder and conductive agent. DETAILED DESCRIPTION - Preparation of activated carbon composite graphene foam electrode sheet involves adding oxidized graphite and polyacrylonitrile to a ball mill, ball-milling, adding mixed solution of ethanol and water, ultrasonically processing, forming a oxidized graphite suspension, adding foam nickel, evaporating solvent, providing in a muffle furnace in hydrogen-nitrogen mixed gas atmosphere, reacting, naturally cooling to room temperature, immersing obtained product in hydrochloric acid, reacting, obtaining graphene foam, adding activated carbon to anhydrous ethanol, ultrasonically processing, coating resultant activated carbon ethanol suspension on the graphene foam, drying, and cooling.
