· JVASP-47558· Li5VSi2O8

Li₅VSi₂O₈ is a lithium vanadium silicate ceramic compound that belongs to the family of mixed-metal oxides with potential electrochemical activity. This material is primarily of research interest for energy storage applications, particularly as a cathode or electrolyte component in lithium-ion battery systems, where the combination of lithium, vanadium, and silicon oxides offers tunable redox chemistry and ionic conductivity. Engineers would evaluate this compound for next-generation battery architectures seeking alternatives to conventional oxide cathodes, though it remains largely in the experimental phase rather than established production.
