Abstract: The discovery of the $LiMOCl_4 (M = Nb, Ta)$ oxyhalides is excitingfor the field of solid-state batteries as they offer similar benefits to other halidesolid electrolytes in terms of electrochemical stability, but with high ionicconductivities exceeding $10 mS·cm^{−1}$ . Analogous materials have also beensynthesised with $Na^+$ as the mobile cation making them attractive for Na-ionsolid-state battery applications as well. However, challenges remain, forexample, their poor reduction stabilities necessitate additional separator layerswhen used with metal anodes. In this perspective, an overview is providedof the known compositions, their structures, stabilities, syntheses, and theirsuggested conduction mechanisms, with an outlook into what developmentsare needed to see their adoption into solid-state batteries. A comparisonwill be made between the $LiMOCl_4$ and $NaMOCl_4$ materials, highlightingthe experimental and theoretical challenges when working with this class ofmaterials. While these oxyhalides are promising for use in solid-state batteries,research in this class of materials is still in its infancy, and further research intounderstanding their structure, processability in air and with solvents, and theirpotential usage as cathode coatings needs to be explored in greater depth.
