· Li4 Fe4 O12

Li₄Fe₄O₁₂ is a lithium iron oxide compound with semiconductor properties, belonging to the family of transition metal oxides used in electrochemical and energy storage applications. This material is primarily of research interest for lithium-ion battery components and solid-state electrolyte systems, where its mixed-valence iron chemistry and lithium mobility make it a candidate for enhancing ionic conductivity and cycle stability. While not yet a commercial commodity material, compounds in this lithium-iron-oxide family are being investigated as alternatives to conventional cathode and electrolyte materials to improve energy density and thermal stability in next-generation battery architectures.
