· 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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
