Li3 V4 O8

Li₃V₄O₈ is a mixed-valence vanadium oxide compound with lithium, belonging to the class of transition metal oxides that exhibit semiconductor behavior. It is primarily investigated as a cathode material and electrochemical storage component in lithium-ion battery research, where its layered structure and variable oxidation states enable reversible lithium insertion and extraction. The material is notable in exploratory energy storage applications due to its potential for high capacity and structural stability compared to conventional oxide cathodes, though it remains largely in the research phase rather than established commercial production.
