▎ 摘　　要

NOVELTY - Manufacturing a storage battery, comprises: forming a first mixture comprising an active material, graphene oxide and a solvent; evaporating the solvent in the first mixture to form a second mixture comprising the active material and the graphene oxide; and reducing the graphene oxide in the second mixture to form a graphene, where the step of reducing the graphene oxide is performed (i) in a reducing solution comprising a reducer and an organic solvent, or (ii) by immersing the second mixture in a reducing solution comprising a reducer and an organic solvent. USE - The method is useful for manufacturing a storage battery, which is used in an electronic device (claimed). ADVANTAGE - The method: manufactures storage battery with high capacity per unit volume of the electrode; and utilizes the reducer which allows fabrication of a storage battery electrode through highly safe chemical reduction of graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electronic device comprising the storage battery.
