· JVASP-135377· LiYS

LiYS is a lithium yttrium sulfide ceramic compound belonging to the sulfide ceramic family, which combines ionic bonding characteristics typical of ceramics with sulfide chemistry. This material is primarily of research interest for solid-state energy storage and optoelectronic applications, where its ionic conductivity and thermal stability make it a candidate for next-generation solid electrolytes in lithium-ion batteries and potentially for infrared optical components. While not yet widely deployed in mainstream industrial production, LiYS represents an emerging class of sulfide-based ceramics being explored as alternatives to oxide ceramics in high-performance energy storage systems where improved ionic transport and stability at elevated temperatures are advantageous.

Regulatory Screening

Environmental

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.
