· VS2

VS2 is a vanadium sulfide compound, a transition metal chalcogenide that belongs to the family of layered 2D materials and advanced ceramics. It has been studied primarily in research contexts for energy storage and catalytic applications, where its electronic and structural properties make it a candidate for next-generation battery electrodes, supercapacitors, and heterogeneous catalysis. While not yet established as a mainstream engineering material like conventional alloys or ceramics, VS2 is notable for its potential in electrochemical devices where layered crystal structures enable high surface area and ion intercalation.
