· Li4 Fe3 O2 F6

Li₄Fe₃O₂F₆ is an inorganic lithium iron oxide fluoride compound being developed as a solid-state electrolyte material for advanced battery systems. This is primarily a research-phase material within the broader family of lithium-conducting ceramics and hybrid oxyfluorides, designed to enable high energy density solid-state lithium batteries by replacing conventional liquid electrolytes. Its mixed anion composition (oxide and fluoride) is being explored to optimize ionic conductivity and electrochemical stability, making it relevant for next-generation energy storage where improved safety, cycle life, and energy density over conventional lithium-ion technology are critical.
