CoSe2

Cobalt diselenide (CoSe2) is an intermetallic compound belonging to the transition metal chalcogenide family, characterized by a layered crystal structure similar to pyrite. While primarily investigated in advanced materials research rather than established industrial production, CoSe2 has emerged as a promising candidate for electrochemical energy storage and conversion applications due to its electronic properties and surface reactivity. Engineers consider this material for next-generation battery electrodes, electrocatalysts, and supercapacitor systems where its conductivity and catalytic activity offer advantages over conventional oxide or sulfide alternatives in cost-sensitive or performance-demanding scenarios.
