Acid‐Alkaline Electrolytes: A High Energy Density Aqueous Battery Achieved by Dual Dissolution/Deposition Reactions Separated in Acid‐Alkaline Electrolyte (Adv. Energy Mater. 12/2020)

In article number 1903589, Xiaowei Chi, Yu Liu and co-workers demonstrate a high-energy-density Zn–Mn2+ aqueous battery system by coupling an acid-alkaline dual electrolyte and dual dissolution/deposition reactions of both the anode and cathode. The new Zn–Mn2+ batteries show high coulombic efficiency and excellent cycling stability in both flow and stationary modes.
