The present disclosure describes a rechargeable zinc ion battery, in which anodic zinc will be electrochemically dissolved as Znions, diffuses to the cathodic electrode/electrolyte interface through the electrolyte, and zinc ions are subsequently intercalated into manganese dioxide during discharging. In charging, above-mentioned process will be reversed. The rechargeable zinc ion battery comprises a cathode formed from a compressed mixture of alpha manganese dioxide particles, electrically conductive particles and one or more binder(s); a zinc anode separated from cathode; an aqueous electrolyte contains zinc ions in which the pH value may be controlled between 4 and 7.
