· Ni1 S2

Nickel disulfide (NiS₂) is a layered semiconductor compound belonging to the transition metal dichalcogenide family, characterized by strong metal-sulfur bonding and tunable electronic properties. This material is primarily investigated in research contexts for energy storage applications (battery electrodes and supercapacitors), photocatalysis, and emerging optoelectronic devices, where its semiconductor behavior and relatively high mechanical stiffness make it attractive compared to graphene or other carbon-based alternatives for applications requiring both structural integrity and electrochemical activity.

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.
