NaVS is a sodium vanadium sulfide compound that belongs to the family of metal chalcogenides and layered transition metal sulfides. This material is primarily of research and development interest for energy storage applications, particularly as a potential cathode or electrode material in sodium-ion batteries and other electrochemical systems seeking alternatives to lithium-based chemistries. Sodium vanadium sulfides are studied for their ion intercalation properties and potential to enable cost-effective, abundant-element battery technologies suited for stationary energy storage and emerging markets where lithium supply constraints are a concern.
