Title: Fluorine-doped antiperovskite electrolyte for all-solid-state Lithium-ion batteries

A fluorine-doped antiperovskite Li-ion conducto Li 2(OH)X (X=Cl, Br) is shown to be a promising candidat for a solid electrolyte in an all-solid-state Li-ion rechargeabl battery. Substitution of F¯ for OH¯ transforms orthorhombi Li 2OHCl to a room-temperature cubic phase, which show electrochemical stability to 9 V versus Li +/Li and two orders o magnitude higher Li-ion conductivity than that of orthorhombi Li 2OHCl. As a result, an all-solid-state Li/LiFePO 4 with F-dope Li 2OHCl as the solid electrolyte showed good cyclability an a high coulombic efficiency over 40 charge/discharge cycles
