· Rb4 Li2 V2 S8

Rb₄Li₂V₂S₈ is a mixed-metal sulfide semiconductor compound containing rubidium, lithium, and vanadium in a layered or framework crystal structure. This is a research-stage material being investigated for solid-state battery electrolytes and ion-conducting applications, where the combination of alkali metals (Rb, Li) with vanadium sulfide provides potential for high ionic conductivity and electrochemical stability. The material belongs to an emerging class of thiophosphate and sulfide-based solid electrolytes that offer advantages over oxide ceramics in terms of mechanical flexibility and wider electrochemical windows, making it relevant for next-generation energy storage where conventional liquid electrolytes present safety or performance limits.
