· JVASP-43570· Li2Fe3F8

Li2Fe3F8 is a lithium iron fluoride compound under investigation as a potential cathode or electrochemical material for advanced battery and energy storage systems. This research-stage material belongs to the family of transition metal fluorides, which are studied for their high theoretical energy density and electrochemical activity in lithium-ion and beyond-lithium battery chemistries. While not yet in widespread commercial production, materials in this class are pursued by battery researchers seeking alternatives to conventional oxide cathodes, particularly for applications demanding high volumetric energy density or improved thermal stability.
