Abstract:
... The Mn²⁺ dissolution of MnO₂ cathode materials causes rapid capacity decay in aqueous zinc batteries. We herein show that the dissolved Mn²⁺ can be deposited back to the cathode with the aid of a suitable conductive agent. The active material is thus retained for energy storage, and this MnO₂/Mn²⁺ redox process also provides capacity. In the Mn²⁺ free ZnSO₄ electrolyte, MnO₂ delivers 325 mA h g⁻¹ ...
