Na1 V2 S4

Na₁V₂S₄ is a layered vanadium sulfide semiconductor compound combining sodium, vanadium, and sulfur in a crystalline structure. This material is primarily explored in research contexts for energy storage and photocatalytic applications, particularly as a candidate for battery cathodes, supercapacitors, and photoelectrochemical devices where its mixed-valence vanadium chemistry and layered structure offer potential advantages in ion transport and electron transfer. The compound represents an emerging alternative to conventional vanadium oxides and lithium-based cathode materials, with ongoing investigation into its electrochemical stability and catalytic performance in laboratory and prototype-scale systems.
