· JVASP-12373· Cr2CoS4

Cr2CoS4 is a quaternary transition metal sulfide compound combining chromium and cobalt with sulfur, belonging to the thiospinel or related metal chalcogenide family. This material is primarily investigated in research contexts for electrochemical energy storage and catalysis applications, where its mixed-valence transition metal composition and sulfide chemistry offer potential advantages in electron transfer and ion transport. Its development is driven by the search for high-performance, earth-abundant alternatives to precious metal catalysts in batteries, supercapacitors, and electrocatalytic systems.
