· TiS2

Titanium disulfide (TiS2) is a layered transition metal dichalcogenide semiconductor composed of titanium and sulfur atoms arranged in a hexagonal crystal structure. The material is primarily investigated in research contexts for energy storage and intercalation chemistry applications, where its layered structure enables efficient ion insertion and extraction. TiS2 is notable as a cathode material candidate for lithium-ion and sodium-ion batteries, and also shows promise in supercapacitors and electrochemical sensing, where its two-dimensional character and tunable electronic properties offer advantages over conventional layered oxides.

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.
