▎ 摘  要

NOVELTY - Preparing zinc-cobalt-nickel oxide/graphene/ANF composite thin-film electrode involves dissolving zinc salt, nickel salt, cobalt salt, cetrimonium bromide (CTAB) and ammonium fluoride (NH4F) in water and stir to obtain homogeneous mixed solution. The graphene oxide dispersion liquid mixed with uniform mixed solution, stir to obtain uniform mixing system 1 and perform hydrothermal reaction to obtain reaction product. The reaction product is separated by extraction, washed, and dried to obtain zinc cobalt nickel oxide/rGO. The zinc-cobalt-nickel oxide/rGO dissolve in dimethyl sulfoxide (DMSO) and disperse ultrasonically until there are no solid particles to obtain zinc-cobalt-nickel oxide/rGO solution. The zinc cobalt nickel oxide/rGO solution, carbon black and ANF solution is mixed and stir to obtain uniform mixing system II. The vacuum pumping method is used for homogeneous mixing system 2 to assemble layers to obtain zinc-cobalt-nickel oxide/graphene/ANF composite thin-film electrode. USE - Method for preparing zinc-cobalt-nickel oxide/graphene/ANF composite thin-film electrode. ADVANTAGE - The method enables to prepare zinc-cobalt-nickel oxide/graphene/ANF composite thin-film electrode has high energy storage and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a capacitor, which is coated with a solid electrolyte on a composite thin-film electrode, which uses a zinc-cobalt-nickel oxide/graphene/ANF composite film electrode.
