· Li4 V4 O8

Li₄V₄O₈ is a mixed-valence lithium vanadium oxide ceramic compound that belongs to the family of vanadium-based metal oxides with potential electrochemical activity. This material is primarily investigated in research and development contexts for energy storage and battery applications, where vanadium oxides are explored as cathode or electrode materials due to their variable oxidation states and ionic conductivity. Li₄V₄O₈ is notable within vanadium oxide systems for its mixed V³⁺/V⁴⁺ character, which can influence lithium-ion intercalation behavior; however, it remains largely experimental rather than a commercial material in widespread industrial use.
