· Na1 V1 S2 O8

Na₁V₁S₂O₈ is a vanadium-based mixed-valence oxide sulfide compound belonging to the class of layered transition metal chalcogenides, synthesized primarily for research into ion-conduction and energy-storage materials. This compound is investigated experimentally in solid-state electrochemistry and battery research communities, where the combination of vanadium redox activity and sulfur coordination offers potential for sodium-ion conduction pathways and cathode/anode functionality. Its appeal lies in the abundance of sodium and vanadium compared to lithium-based alternatives, making it a candidate for cost-effective energy storage systems, though it remains largely in the exploratory phase rather than in widespread industrial production.
