· JVASP-43733· Li6FeO4F2

Li6FeO4F2 is an experimental lithium iron oxide fluoride ceramic compound being investigated for electrochemical and energy storage applications. This material belongs to the family of mixed-anion ceramics (oxyfluorides) where fluorine substitution modifies the crystal structure and ionic transport properties compared to conventional oxide counterparts. Research interest centers on its potential as a solid-state electrolyte or cathode material in next-generation lithium-ion batteries, where the fluoride component can enhance ionic conductivity and electrochemical stability.
