LaCl₃-based sodium halide solid electrolytes with high ionic conductivity for all-solid-state batteries.

ABSTRACT: To enable high performance of all solid-state batteries, a catholyte should demonstrate high ionic conductivity, good compressibility and oxidative stability. Here, a LaCl₃-based Na⁺ superionic conductor (Na_1-xZr_xLa_1-xCl₄) with high ionic conductivity of 2.9 × 10^-4S cm^-1 (30 °C), good compressibility and high oxidative potential (3.80 V vs. Na₂Sn) is prepared via solid state reaction combining mechanochemical method. X-ray diffraction reveals a hexagonal structure (P6₃/m) of Na_1-xZr_xLa_1-xCl₄, with Na⁺ ions forming a one-dimensional diffusio
