{"product_id":"cbssepcp2s5","title":"Phosphorus Pentasulfide (P2S5, \u003e99.9%) Precursor Powder for Sulfide Solid-State Electrolyte Synthesis, 100 g\/bottle, CBSSEPCP2S5","description":"\u003cp\u003ePhosphorus pentasulfide (P2S5) is the primary network-forming precursor used alongside Li2S to synthesize sulfide-based solid-state electrolytes (SSEs). It provides the structural backbone (PS4^{3-} tetrahedra) responsible for creating the open framework that allows rapid lithium-ion transport. Managing P2S5 requires precise control because its chemical stability, purity, and particle morphology directly dictate the ionic conductivity and electrochemical stability window of the resulting electrolyte.\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003eIn sulfide systems, P2S5 reacts with Li2S to modify the sulfide network. The ratio between the modifier (Li2S) and the network former (P2S5) determines the local structural units formed: (1) \u003cstrong\u003eHigh Li2S Ratios (e.g., 3Li2S P2S5 or Li3PS4)\u003c\/strong\u003e: Completely breaks down the P2S5 cage to form isolated, highly symmetrical ortho-thiophosphate [PS4]^{3-} tetrahedra. This structure provides optimal pathways for Li+ hopping and minimizes electronic conductivity. (2) \u003cstrong\u003eArgyrodites (Li6PS5X)\u003c\/strong\u003e: P2S5 provides the central [PS_4]^{3-} units, which are surrounded by free sulfide (S^{2-}) and halide (X-) ions, achieving ionic conductivities exceeding 10^{-3} S cm-1. (3) \u003cstrong\u003eMeta- and Pyro-thiophosphates\u003c\/strong\u003e: Lower ratios of Li2S yield shared tetrahedra frameworks (like [P2S7]^{4-} or [P2S6]^{4-}), which generally exhibit lower ionic conductivities but can offer unique mechanical flexibility.\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: 30.5755%; 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\u003eCBSSEPCP2S5 (C-BSSE-PC-P2S5)\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\u003e222.3 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: 30.5755%; height: 46.8875px;\"\u003e\u003cem\u003eParticle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; 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\u003e\n\u003ctd style=\"width: 30.5755%;\"\u003e\u003cem\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%;\"\u003e\n\u003cp\u003e\u003cspan\u003e280-284 °C (lit.)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.5755%;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%;\"\u003e\n\u003cp\u003e\u003cspan\u003e2.09 g\/mL at 25 °C (lit.)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 10px;\"\u003eWater Level\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; 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\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 P2S5 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:\/\/pubs.acs.org\/doi\/full\/10.1021\/acsomega.4c03784\"\u003e\u003cspan\u003eZ.
