Lithium diselenide (LiSe₂) is an inorganic ceramic compound belonging to the lithium chalcogenide family, characterized by ionic bonding between lithium cations and selenide anions. This material is primarily investigated in solid-state battery research and advanced electrolyte applications, where its ionic conductivity and electrochemical stability make it attractive for next-generation solid-state lithium-ion batteries seeking to replace conventional liquid electrolytes. LiSe₂ represents an emerging material class rather than an established commercial ceramic; its potential lies in enabling higher energy density, improved thermal stability, and safer battery systems compared to conventional lithium-ion technologies.
