· Li4 Fe2 O2 F6

Li4Fe2O2F6 is a mixed-valence lithium iron oxide fluoride compound belonging to the class of lithium-based inorganic solids with potential electrochemical activity. This material is primarily of research interest rather than established industrial use, positioned within the family of lithium iron fluorides and oxyfluorides that are being investigated as cathode materials and solid-state electrolyte candidates for next-generation lithium-ion and all-solid-state battery systems. The combination of lithium, iron, oxygen, and fluorine offers tunable ionic conductivity and electrochemical stability, making it notable compared to conventional oxide cathodes for its potential to enable higher energy density and improved thermal stability in advanced battery chemistries.
