▎ 摘  要

NOVELTY - Manufacture of aqueous zinc-ion battery positive electrode material involves coating the conductive polymer on the surface of the positive electrode active material by gas phase polymerization or liquid phase polymerization. The conductive polymer formed on the surface of the positive electrode material of the aqueous zinc ion battery is ordered. The positive electrode active material comprises graphene, manganese-based oxide, vanadium-based oxide, vanadium-based nitrogen oxide, Prussian blue and its analogs, metal/covalent organic framework compound, organic electrochemical materials, layered MXene, layered sulfides, and layered selenide. USE - Manufacture of aqueous zinc-ion battery positive electrode material. ADVANTAGE - The prepared positive electrode material overcomes the dissolution problem of the active material in the existing positive electrode material, realizes the efficient utilization of the positive electrode active material, enhances the storage of zinc ions, and further improves the rate performance and cycle stability of the battery.
