▎ 摘  要

NOVELTY - Aqueous zinc ion full battery comprises a positive electrode, a negative electrode, a membrane between the positive and negative electrodes and an electrolytic solution with ion conductivity and an electrolyte additive. The positive electrode comprises a current collector, a positive active material, a conductive agent and a binder. The negative electrode comprises a current collector, a cathode active material, a conductive agent and a binder. The electrolyte additive is soluble salt of zinc as solute, water as solvent and liquid or gel state material with ion conductivity. The electrolyte additive is soluble salt containing bivalent manganese. USE - Rechargeable and dischargable aqueous zinc ion full battery. ADVANTAGE - The system utilizes anthraquinone organic compound material with reduction potential higher than zinc deposition potential to replace the metal zinc cathode, which can avoid the formation of zinc dendrite, at the same time, solves the problem of corrosion and passivation of zinc cathode, and improves the safety of the battery.
