Li6 Fe2 O2 F6

Li₆Fe₂O₂F₆ is an experimental lithium iron oxide fluoride ceramic compound belonging to the family of mixed-anion oxyfluorides. This material is primarily of research interest for solid-state energy storage and ionic conductor applications, where the combination of lithium, iron, and fluoride ions creates a framework potentially suitable for fast Li⁺ transport. Unlike conventional lithium oxide ceramics, the fluoride substitution can modify crystal structure and ionic conductivity pathways, making it relevant to researchers developing next-generation solid electrolytes and cathode materials for all-solid-state batteries.
