Abstract

Electrochemical properties of A₂MnPO₄F (A = Na/Li) were investigated both experimentally and with first principles calculations. A new Li₂MnPO₄F phase was successfully synthesized for the first time. A one alkali metal ion reaction occurred reversibly within a reasonable voltage window and a two alkali metal ion reaction took place at higher voltages.
