Li5 V2 Fe3 O10

Li₅V₂Fe₃O₁₀ is a mixed-valence oxide semiconductor composed of lithium, vanadium, iron, and oxygen, belonging to the family of layered or tunnel-structure metal oxides. This is primarily a research-stage material investigated for energy storage and electrochemical applications, particularly as a cathode material or electrolyte component in lithium-ion batteries, where the combination of multiple redox-active metal centers (vanadium and iron) offers potential for high capacity and tunable electrochemical behavior. The material is notable within exploratory battery chemistry for its ability to leverage both transition metals for charge compensation, though it remains largely in academic development rather than commercial production.
