· Li4 Fe4 O2 F8

Li₄Fe₄O₂F₈ is an experimental lithium iron oxide fluoride compound belonging to the mixed-anion ceramic family, designed for electrochemical energy storage applications. This material is primarily investigated in battery research contexts—particularly as a potential cathode or solid-state electrolyte component—due to its mixed anionic framework (oxide and fluoride) which can enhance ionic conductivity and structural stability compared to single-anion alternatives. While not yet commercialized at scale, compounds in this structural class are notable for their potential to improve energy density and cycle life in next-generation lithium-ion and solid-state battery systems.
