For many systems, this is followed by a post-annealing step at 200°C–550°C to precipitate highly conductive crystalline or glass-ceramic phases (e.g., Argyrodite or Li7P3S11). (2) \u003cstrong\u003eSolid-State Sintering\u003c\/strong\u003e: Stoichiometric mixtures of Li2S, P2S5, and modifiers are sealed under vacuum in quartz ampoules and heated directly to temperatures ranging from 500°C to 900°C (or up to 1100°C for melt-quenching systems like Li2S–SiS2). High crystallinity, though grain boundary engineering is required during subsequent processing to ensure seamless interparticle contact. (3) \u003cstrong\u003eLiquid-Phase\/Solution Synthesis\u003c\/strong\u003e: Dissolving Li2S and co-precursors in anhydrous organic solvents such as tetrahydrofuran (THF), acetonitrile, or ethanol. The reaction proceeds at moderate temperatures (25°C–80°C), followed by vacuum drying and calcination. It enables low-temperature scalable wet-chemical processing, slurry casting, and excellent infiltration into porous, tortuous cathode frameworks.\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; height: 301.038px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 46.8875px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 46.8875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 46.8875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBSSEPCLS (C-BSSE-PC-LS)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.99%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 71.2px;\"\u003e\u003cem\u003eImpurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 71.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eNa\u0026lt;34 ppm, Ca\u0026lt;30 ppm, Mg\u0026lt;5 ppm, K\u0026lt;8 ppm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFe\u0026lt;4 ppm Al\u0026lt;4 ppm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e45.95 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 46.8875px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 46.8875px;\"\u003e\u003cem\u003eParticle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 46.8875px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~30 um\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 10px;\"\u003eWater Level\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;50 ppm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 28.5625px;\"\u003e\n\u003ctd style=\"width: 30.6028%; height: 28.5625px;\"\u003e\u003cem\u003eXRD\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0375%; height: 28.5625px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBSSEPCLS_XRD_100x100.png?v=1779895312\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: (1) Please store the Li2S powder in a glovebox due to its air\/humidity sensitivity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.nature.com\/articles\/s41467-025-64924-8\"\u003e\u003cspan\u003eY.
