· Li1 Fe1 O1 F1

Lithium iron oxyfluoride (LiFeOF) is a mixed-anion compound combining lithium, iron, and oxygen/fluorine phases, belonging to the fluoride-oxide ceramic semiconductor family. This material is primarily investigated in electrochemistry and battery research contexts, where the combination of ionic lithium transport pathways and iron redox activity makes it attractive for next-generation lithium-ion battery cathodes and solid-state electrolyte applications. Its competitive advantage lies in potential for improved ionic conductivity and structural stability compared to single-anion oxide or fluoride phases, though it remains largely a research-stage compound with limited commercial deployment.
