· Li2 W1 S4

Li₂WS₄ is a ternary layered semiconductor compound combining lithium, tungsten, and sulfur, belonging to the family of transition metal dichalcogenides and their derivatives. This material is primarily investigated in research contexts for energy storage and optoelectronic applications, where its layered crystal structure and electronic properties offer potential advantages in lithium-ion batteries, solid-state electrolytes, and thin-film photovoltaic or photoelectrochemical devices. Compared to conventional battery materials and simple dichalcogenides, the lithium-tungsten-sulfide system is notable for combining ionic conductivity pathways (via lithium) with the electronic and catalytic properties of tungsten disulfide, making it of particular interest for next-generation energy devices, though it remains largely in the development and optimization phase.

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.
