· Li2 Fe3 O3 F5

Li₂Fe₃O₃F₅ is an anionic mixed-valence iron oxide fluoride compound belonging to the family of lithium iron fluoroxides, which are layered ionic semiconductors under active research for battery and electrochemical applications. This material is primarily investigated in laboratory and pilot-scale research contexts for potential use as a cathode material or electronic component in advanced lithium-ion batteries and solid-state electrochemical devices, where its combined iron, oxygen, and fluorine chemistry offers opportunities for tuning electronic structure and ion transport. Engineers evaluating this compound should recognize it as an emerging functional ceramic rather than a mature commercial material, positioned within the broader exploration of fluoride-based and transition-metal oxide semiconductors for next-generation energy storage systems.
