▎ 摘  要

NOVELTY - Preparing manganese(IV) oxide/graphene composite material, comprises taking graphite as anode, foamed nickel as cathode, and mixed solution of sodium sulfate and potassium permanganate as electrolyte, and then co-assembling using electrochemical one-step method to obtain final product. USE - The composite material is useful in electrode in electronic device, and in super capacitor (all claimed). ADVANTAGE - The composite material has excellent capacitance of 607F/g at 1 A/g, high rate performance and super-cycle stability, and 94.1% after 10,000 charge-discharge cycles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manganese(IV) oxide/graphene composite material, prepared by above mentioned method.
