{"product_id":"cbssepcsns2","title":"Tin Disulfide (SnS2, 99.9%) Precursor Powder for Sulfide Solid-State Electrolyte Synthesis, 25 g\/bottle, CBSSEPCSnS2","description":"\u003cp\u003eTin disulfide (SnS2) is an important network-forming precursor used to synthesize low-cost, chemically stable sulfide solid-state electrolytes (SSEs), such as the Li2S-SnS2 and Li4SnS4 frameworks, as well as multi-cation systems like Li10SnP2S12 (LSTPS). As a replacement for expensive germanium (Ge) in the classic LGPS structure, tetravalent tin (Sn}^{4+}) offers an earth-abundant, highly cost-effective alternative. Furthermore, [SnS4]^{4-} tetrahedra exhibit excellent structural stability and a lower reduction potential against lithium metal compared to phosphorus-only networks, helping to mitigate rapid dendritic short-circuiting at the anode interface. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Energy Mechanochemical Ball Milling\u003c\/strong\u003e: Mechanochemical amorphization is highly effective for tin-based systems because the mechanical energy breaks down the layered SnS2 sheets, facilitating room-temperature coordination with lithium sulfide (Li2S).

Ensure the jar is sealed tightly with a fresh Viton O-ring. (3) \u003cem\u003eMilling Run\u003c\/em\u003e: Run the planetary ball mill at 400 to 500 RPM for 15 to 24 hours. Program interval reversals and rest cooling cycles (e.g., 30 minutes of milling followed by 10 minutes of rest) to prevent internal thermal spikes from inducing premature phase separation. (4) \u003cem\u003ePost-Annealing Crystallization\u003c\/em\u003e: The resulting amorphous glass-ceramic powder is recovered, pelletized, vacuum-sealed in a quartz tube, and annealed at 400°C to 450°C for 12 hours. This triggers the nucleation of the highly conductive, pure crystalline Li4SnS4 phase.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 331.688px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 46.8875px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 46.8875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 46.8875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBSSEPCSnS2 (C-BSSE-PC-SnS2)\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: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1315-01-1\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: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9%\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: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e182.8 g\/mol\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: 30.5755%; height: 35.6px;\"\u003eWater Level\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;0.01 wt% (battery grade)\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: 30.5755%; height: 35.6px;\"\u003eBoling Point\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e600℃ (it thermally decomposes into tin(II) sulfide (SnS) and sulfur gas at approximately 600 °C)\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: 30.5755%; height: 35.6px;\"\u003eDensity\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e4.5 g\/cm3\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: 30.5755%; height: 35.6px;\"\u003ePackage Grade\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e25 g\/bottle\u003c\/span\u003e\u003c\/p\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: Please store the SnS2 powder in a dry place (glovebox is preferred 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:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsaem.0c02671\"\u003e\u003cspan\u003eW.
