Li4 V2 O4 F4

Li₄V₂O₄F₄ is an inorganic ceramic compound combining lithium, vanadium, oxygen, and fluorine, classified as a semiconductor with potential electrochemical properties. This is primarily a research-phase material of interest for next-generation energy storage and ion-conducting applications, rather than an established commercial compound; the fluorine-doped vanadium oxide framework positions it within the family of materials explored for solid-state battery electrolytes, cathode materials, and fast-ion conductors where combining high electrochemical stability with ionic mobility is critical.
