· Li4 Fe4 O4 F8

Li₄Fe₄O₄F₈ is an experimental lithium iron oxyfluoride ceramic compound belonging to the class of mixed-anion materials, combining oxide and fluoride ligands in a single framework structure. This material is primarily of research interest for energy storage applications, particularly as a potential cathode or electrolyte component in advanced lithium-ion and solid-state battery systems, where the fluoride component is expected to enhance ionic conductivity and electrochemical stability compared to conventional oxide-only ceramics.
