▎ 摘　　要

NOVELTY - A nickel hydroxide/graphene oxide sheet capacitor electrode material is prepared by utilizing nickel sulfate hepta hydrate as a nickelous source, which is prepared through single-step reflux reaction. Inherent natures of structures of nickel hydroxide and graphene are combined in the mixture. Graphite oxide is directly restored to the graphene through potassium hydroxide, and the combined nickel hydroxide is adhered to the surface of the graphene fluffily. USE - Nickel hydroxide/graphene oxide sheet capacitor electrode material for use in a super capacitor. ADVANTAGE - The material has improved electrical conductivity, and is easy to operate, low in cost, long in cycle life, free of pollution and high in efficiency.
