Abstract

Abstract Rechargeable aqueous Zn/MnO 2 batteries are very attractive large‐scale energy storage technologies, but still suffer from limited cycle life and low capacity. Here the novel adoption of a near‐neutral acetate‐based electrolyte (pH ≈ 6) is presented to promote the two‐electron Mn 4+ /Mn 2+ ...
