· Li2 V2 P4 O14

Li₂V₂P₄O₁₄ is a lithium vanadium phosphate ceramic compound that functions as a semiconductor material, belonging to the polyphosphate family of inorganic compounds. This material is primarily of research and developmental interest for energy storage and electrochemical applications, where its layered structure and mixed-valence transition metal composition (vanadium) offer potential for ion transport and electron conduction. While not yet widely deployed in commercial products, compounds in this material family are being investigated as cathode materials, solid electrolytes, and electrochemically active phases in advanced lithium-ion and solid-state battery systems due to their thermal stability and tunable electrochemical properties.
