Cobalt disulfide (CoS₂) is a transition metal chalcogenide compound that belongs to the pyrite family of materials. It is primarily investigated as an electrode material in energy storage and catalysis applications, particularly for electrochemical devices requiring sulfide-based active materials. CoS₂ is notable for its potential in lithium-ion batteries, supercapacitors, and hydrogen evolution catalysis, where its mixed-valence cobalt centers and layered electronic structure offer advantages over traditional carbon or oxide alternatives.
