In article number 1903698, Xiayin Yao, Zhong‐Shuai Wu, Yan Yu and co‐workers design an ultrahigh energy density (1503 Wh kg −1 based on the cathode active material) aqueous Zn–Mn 2+ battery by coupling an acid‐alkaline dual electrolyte and dual dissolution/deposition reactions of both the anode and cathode. The new Zn–Mn 2+ batteries show high coulombic efficiency and excellent cycling stability.
