▎ 摘　　要

NOVELTY - A hollow corn-like cobalt oxides-nickel cobaltite/nitrogen-doped graphene flexible electrode material preparing method involves dispersing graphene oxide, nickel nitrate hexahydrate and cobalt nitrate hexahydrate in an aqueous solution of ethylenediamine and uniformly dispersed to obtain a mixed solution. The mixed solution is transferred to a microwave reactor and subjected to a microwave reaction after completion, the product is washed with deionized water and ethanol, respectively, to obtain product. USE - Method for preparing hollow corn-like cobalt oxides-nickel cobaltite/nitrogen-doped graphene flexible electrode material that is utilized for preparing flexible super capacitor electrode (claimed). ADVANTAGE - The material has improved capacitance and cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a hollow corn-like cobalt oxides-nickel cobaltite/nitrogen-doped graphene flexible electrode material prepared by the method.
