Li₂FeBO₄ is an inorganic ceramic compound combining lithium, iron, boron, and oxygen—a mixed-metal borate that belongs to the family of lithium-iron borates. This material is primarily investigated in research contexts for energy storage and solid-state electrolyte applications, where its ionic conductivity and structural stability at elevated temperatures make it a candidate for advanced lithium-ion battery systems and solid electrolyte membranes. Its appeal lies in leveraging iron's abundance and cost-effectiveness compared to conventional electrolyte materials, though it remains largely in the development phase rather than widespread commercial deployment.
