Li3TaO4 is an inorganic ceramic compound combining lithium, tantalum, and oxygen, belonging to the family of lithium tantalates and mixed-metal oxides. This material is primarily investigated in research settings for solid-state battery applications, where its ionic conductivity and electrochemical stability make it a candidate for solid electrolytes in next-generation lithium-ion and lithium-metal batteries. Its high density and rigid crystal structure offer potential advantages in energy storage systems requiring mechanical robustness and chemical compatibility with lithium metal anodes, though commercial adoption remains limited compared to more established solid electrolyte materials.
