· JVASP-10489· Li4TiO4

Li₄TiO₄ is an inorganic ceramic compound containing lithium, titanium, and oxygen, belonging to the family of lithium titanates. This material is primarily investigated in battery research and solid-state electrolyte applications, where its ionic conductivity and structural stability at operating temperatures make it a candidate for next-generation lithium-ion and all-solid-state battery systems. Engineers consider lithium titanates for energy storage when conventional liquid electrolytes present thermal or safety constraints, though Li₄TiO₄ itself remains largely in the research phase relative to established commercial alternatives like lithium phosphates.
