CsFeO2F

CsFeO2F is a mixed-anion ceramic compound combining iron oxide and fluoride phases, belonging to the family of layered or perovskite-related oxyfluorides. This is a research-stage material primarily studied for its potential in energy storage and catalytic applications, where the combination of iron redox activity and fluoride substitution can modify electronic structure and ionic transport properties. The oxyfluoride chemistry makes it a candidate for next-generation battery cathodes, solid electrolytes, or catalytic materials, though it remains largely in the experimental phase with limited commercial deployment compared to established iron oxide or fluoride ceramics.
