Trace Sc 3+ additive (1.0 mol%) is shown to greatly improve the Coulombic efficiency and cycling stability of Zn metal anodes in aqueous ZnSO 4 electrolyte due to the decreased nucleation overpotential and increased kinetics for Zn plating/stripping. Both Zn‖Zn and Zn‖V 2 O 5 cells show enhanced cycling stability and rate capability in the Sc 3+ -modified electrolyte.
