Abstract

A fluorine-doped antiperovskite Li-ion conductor Li₂(OH)X (X=Cl, Br) is shown to be a promising candidate for a solid electrolyte in an all-solid-state Li-ion rechargeable battery. Substitution of F⁻for OH⁻transforms orthorhombic Li₂OHCl to a room-temperature cubic phase, which shows electrochemical stability to 9 V versus Li⁺/Li and two orders of magnitude higher Li-ion conductivity than that of orthorhombic Li₂OHCl. An all-solid-state Li/LiFePO₄with F-doped Li₂OHCl as the solid electrolyte showed good cyclability and a high coulombic efficiency over 40 charge/discharge cycles.
