Investigation of Structure, Ionic Conductivity, and Electrochemical Stability of Halogen Substitution in Solid-State Ion Conductor Li₃YBr _x Cl_6-x.

ABSTRACT: Li₃YX₆ (X = Cl, Br) materials are Li-ion conductors that can be used as solid electrolytes in all solid-state batteries. Solid electrolytes ideally have high ionic conductivity and (electro)chemical compatibility with the electrodes. It was proven that introducing Br to Li₃YCl₆ increases ionic conductivity but, according to thermodynamic calculations, should also reduce oxidative stability. In this paper, the trade-off between ionic conductivity and electrochemical stability in Li₃YBr _x Cl_6-x halogen-substituted compounds is investigated. The compositions of Li₃YBr_1.5Cl_4.5 and Li₃YBr_4.5Cl_1.5 are reported for the first time, along with
