Insight into the prospects and limitations of mechanochemically-synthesised lithium tetrahalogallates, LiGaX₄ (X = Cl, Br, I), as Li-ion conductors.

ABSTRACT: Halide solid-state electrolytes have attracted significant interest due to their appreciable Li⁺ conductivity at room temperature, good electrochemical stability against oxidation, and favourable compatibility with oxide cathodes. Nevertheless, the family of lithium tetrahalogallates, LiGaX₄ (X = Cl, Br, I), has scarcely been studied and, consequently, their physicochemical properties remained largely unknown. In this work, we report the mechanochemical synthesis of high-purity LiGaX₄ and investigate their crystal structures, thermal, electronic, vibrational, and ionic transport properties through a combination of advanced characterisation techniques and computational methods. Powder X-ray and neutron diffraction confirm that all three phases crystallise in
