▎ 摘　　要

NOVELTY - The method involves adding graphite oxide and nano-carbon fiber to solvent. The solvent is added and mixed with hydrazine hydrate solution to obtain graphene nano-carbon fiber composite suspension. A filter cake is dried and peeled from an upper filter film at temperature of 100 to 50 degrees celsius. Atmosphere heat treatment is finished to obtain a graphene nano-meter carbon fiber composite element. The filter cake is entered into a tubular furnace. Protective gas used is argon gas and reducing gas utilized is hydrogen. USE - Method for manufacturing a graphene nano-carbon fiber composite collector. ADVANTAGE - The method enables adding nano-carbon fiber with graphene oxide suspension solution so as to improve mechanical strength and tensile strength of the graphene nano-carbon fiber composite element. DETAILED DESCRIPTION - The solvent is water, ethanol, isopropanol, propanol and N-methyl pyrrolidone or N-dimethyl formamide. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing a graphene nano-carbon fiber composite collector. '(Drawing includes non-English language text)'
