· JVASP-59896· YCo2S4

YCo2S4 is an yttrium cobalt sulfide compound belonging to the rare-earth transition metal chalcogenide family. This is a research-phase material primarily investigated for electrochemical and energy storage applications due to its mixed-valence transition metal chemistry and layered crystal structure. It represents an emerging class of materials being explored as catalysts and electrode materials where the combination of rare-earth elements with cobalt sulfides offers potential advantages over conventional single-metal sulfides.
