· Li2 Fe5 O5 F7

Li₂Fe₅O₅F₇ is a lithium iron fluoroxide ceramic compound belonging to the family of mixed-valence iron oxyfluorides, which are being actively explored as potential cathode materials and ion conductors for advanced electrochemical devices. This is primarily a research-phase material rather than an established commercial compound; it represents the broader class of fluoride-containing lithium compounds being investigated for next-generation solid-state batteries and fast-ion conductors, where the fluoride component can enhance ionic mobility and structural stability compared to conventional oxide-only ceramics.
