Li₄V₄As₄O₂₀ is a mixed-valence lithium vanadium arsenate ceramic compound belonging to the family of polyanion-framework phosphates and arsenates. This is a research-phase material primarily investigated for energy storage and electrochemical applications due to its potential as a lithium-ion battery cathode material, where the vanadium redox couples and framework structure can enable ionic transport and tunable electrochemical behavior. The arsenic-containing polyanion framework offers structural stability and allows tailoring of electrochemical windows, making it a candidate for next-generation battery chemistries, though industrial adoption remains limited compared to more established olivine and layered oxide cathodes.
