Used as a potential solid-state electrolyte in lithium-ion and lithium-metal batteries due to its high lithium ion conductivity. It serves as a hydrogen storage material when reacting with hydrogen under pressure to form lithium hydride and ammonia. Acts as a catalyst or precursor in the synthesis of other lithium-containing compounds and nitrides. Investigated for use in electrochromic devices and as a reducing agent in organic synthesis. Also explored in research for its role in ammonia synthesis under mild conditions.
