Zusammenfassung:Charge Redistribution In article number 2111901, Young Hwa Jung, Hyun‐Wook Lee, and co‐workers demonstrate that the fast reaction rate activates charge redistribution in manganese hexacyanomanganates, which can mitigate the strong Jahn–Teller effect of high‐spin Mn(III) by solving the unequal number of electrons in eg orbitals. As a result, the dissolution of Mn is effectively suppressed, inducing improved long‐term cyclability in an aqueous electrolyte.
