· Li6 P1 S5 Cl1

Li₆PS₅Cl is a halide-substituted lithium phosphorus sulfide compound belonging to the argyrodite family of solid-state electrolytes. This is an experimental/research material currently under development for next-generation energy storage systems, where it serves as a solid electrolyte alternative to liquid organic electrolytes in all-solid-state battery (ASSB) designs. Engineers and researchers select this material class for its potential to enable higher energy density, improved safety, and better cycle life compared to conventional lithium-ion batteries, though it remains in the laboratory and prototype phase without widespread commercial deployment.

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.
