· MgCo2S4

MgCo2S4 is a ternary metal sulfide compound combining magnesium, cobalt, and sulfur in a thiospinel or related crystal structure. This is an experimental/research material primarily investigated for electrochemical energy storage and catalytic applications, rather than a commercialized engineering material. The cobalt-sulfide family has gained attention for battery cathodes, supercapacitors, and hydrogen evolution catalysts, where the mixed-metal composition can offer improved electron conductivity and surface reactivity compared to binary sulfides.
