▎ 摘　　要

NOVELTY - Preparation of carbon nanotube composite graphene foam electrode sheet involves ball-milling graphite oxide and polyacrylonitrile, adding mixed solution of ethanol and water, ultrasonically dispersing, soaking nickel foam in obtained suspension, evaporating solvent, adding obtained product to a muffle furnace under hydrogen and nitrogen mixed gas protection atmosphere, reacting, cooling, immersing obtained product in hydrochloric acid, reacting, obtained foamed graphene, dispersing carbon nanotubes in anhydrous ethanol, applying obtained suspension on the foamed graphene, and drying. USE - Preparation of carbon nanotube composite graphene foam electrode sheet (claimed). ADVANTAGE - The method enables economical preparation of carbon nanotube composite graphene foam electrode sheet without using a binder and a conductive agent. DETAILED DESCRIPTION - Preparation of carbon nanotube composite graphene foam electrode sheet involves adding graphite oxide and polyacrylonitrile to a ball mill, ball-milling, adding mixed solution of ethanol and water, ultrasonically dispersing, soaking nickel foam in obtained suspension, evaporating solvent, adding obtained product to a muffle furnace under hydrogen and nitrogen mixed gas protection atmosphere, reacting, naturally cooling, immersing obtained product in hydrochloric acid, reacting, obtained foamed graphene, adding carbon nanotubes to an anhydrous ethanol, ultrasonically dispersing, applying the ethanol suspension containing carbon nanotubes on the foamed graphene, drying, cooling and pressing.
