A comparative study on Na2MnPO4F and Li2MnPO4F for rechargeable battery cathodes.
Electrochemical properties of A(2)MnPO(4)F (A = Na/Li) were investigated both experimentally and with first principles calculations. A new Li(2)MnPO(4)F 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.
