Summary: Emerging halides show promise as alternatives for solid-state electrolytes, offering low Li+ migration energy barriers, high electrochemical stability, and beneficial mechanical properties. Mechanochemical synthesis has allowed for the characterization and synthesis of new LiAlX4 compounds, with LiAlBr4 showing the highest room temperature ionic conductivity and LiAlCl4 exhibiting the highest thermal and oxidative stability. Modeling suggests that the Li-ion transport mechanism in each tetrahaloaluminate is closely related to halide polarizability and complex anion motions.
