▎ 摘　　要

NOVELTY - The method involves adding graphite oxide and polypropylene into a ball mill. Carbon nano-tubes are added into absolute ethanol. A ball-milled mixture is added into a mixed solution of ethanol and water to form a suspension. A foamed nickel is subjected to suspension soaking process. Solvent is evaporated and placed in a muffle furnace protected by a hydrogen-nitrogen gas mixture to react in a furnace, where the reaction is completely cooled down. A product is immersed in hydrochloric acid to react to obtain a foam graphene. USE - Method for manufacturing a carbon nanotube-graphene foam composite electrode for use as a current collector. ADVANTAGE - The method enables simplifying carbon nanotube-graphene foam composite electrode manufacturing process and avoiding a need to add a binder and conductive agent to manufacture the electrode, so as to reduce electrode manufacturing cost. The method enables effectively increasing capacity of the electrode after the carbon nanotubes loaded graphene. The method enables providing effective electron and ion conduction channels to achieve high energy density and high power density by using a porous structure of the graphene foam. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing a carbon nanotube-graphee foam composite electrode. '(Drawing includes non-English language text)'
