· JVASP-48722· Li5FeO3F

Li5FeO3F is an experimental lithium iron oxide fluoride ceramic compound being investigated for energy storage and electrochemical applications. This material belongs to the family of lithium-containing mixed-metal oxyfluorides, which are of significant research interest as potential cathode or solid electrolyte materials for next-generation lithium-ion and solid-state batteries. While not yet in widespread commercial use, compounds in this chemical family are pursued for their ionic conductivity, structural stability, and potential to improve battery energy density and safety compared to conventional layered oxide cathodes.
