· JVASP-44638· Li4NbFe3O8

Li4NbFe3O8 is a lithium-niobium-iron oxide ceramic compound that belongs to the family of mixed-metal oxides with potential electrochemical applications. This material is primarily investigated in research contexts for energy storage and solid-state battery technologies, where lithium-containing ceramics offer advantages in ionic conductivity and structural stability at elevated temperatures. The combination of niobium and iron oxides with lithium suggests applications in lithium-ion battery components or solid electrolyte materials, positioning it as an alternative to conventional layered oxide cathodes in next-generation battery systems.
