title: High energy density MnO4-/MnO42-redox couple for alkaline redox flow batteries.
abstract: The MnO4-/MnO42-redox couple has a positive redox potential, high electrochemical reversibility and high solubility, up to 3.62 M at room temperature. Careful optimization of the electrolyte composition and the potential limits eliminates the side reactions, making this redox couple an attractive option for alkaline redox flow batteries.
