Solid-state batteries are considered the next generation of batteries, but they still suffer from high interfacial resistance. One strategy to mitigate the problem is to use coating. We performed a computational screening to find promising cathode coating compositions. Polyanionic oxides are highlighted for good overall characteristics, and LiH 2 PO 4 , LiTi 2 (PO 4 ) 3 , and LiPO 3 are particularly appealing candidates. Furthermore, factors including oxygen bond covalency and Li content are identified to affect oxidation stability of polyanionic oxide coatings.
