Summary: In this study, the authors demonstrate how the fast reaction rate activates charge redistribution in manganese hexacyanomanganates, which helps alleviate the strong Jahn-Teller effect of high-spin Mn(III) by solving the unequal number of electrons in e(g) orbitals. As a result, the dissolution of Mn is effectively suppressed, leading to improved long-term cyclability in an aqueous electrolyte.
