Li5 Fe7 O3 F13

Li₅Fe₇O₃F₁₃ is a mixed-valence lithium iron oxide fluoride ceramic compound belonging to the family of fluoride-based inorganic materials. This composition is primarily of research and developmental interest rather than established in high-volume production; it represents exploration of lithium-iron frameworks doped with fluorine, which can alter ionic conductivity, electrochemical stability, and crystal structure compared to conventional oxide ceramics.
