{"product_id":"cbssepclb","title":"Lithium Bromide (LiBr, Anhydrous, 99.9%) Precursor Powder for Sulfide \u0026 Halide Solid-State Electrolyte Synthesis, 50 or 100 g\/bottle, CBSSEPCLB","description":"\u003cp\u003eIn the synthesis of sulfide-halide solid-state electrolytes—most notably lithium argyrodites (such as Li6PS5Br) and halide-doped glass-ceramics (like Li7P3S11 * LiBr)—lithium bromide (LiBr) serves as a critical dopant precursor. Integrating LiBr into a pure sulfide framework expands the polarizable anion lattice, creates beneficial lithium-ion vacancies, and optimizes the local structural disorder, pushing the room-temperature ionic conductivity of the electrolyte toward or beyond 10^{-3} S cm-1.\u003c\/p\u003e\n\u003cp\u003eCompared to transition metal chlorides like ZrCl4, LiBr is thermally stable and will not sublime or volatilize at typical synthesis temperatures. However, its primary challenge is an extreme susceptibility to moisture. (1) \u003cstrong\u003ePurity Requirements\u003c\/strong\u003e: Standard protocols demand 99.9% (3N) or 99.99% (4N) anhydrous grade (trace metals basis). Impurities like sodium or heavy metals can compromise the electrochemical window or induce unwanted electronic leakage. (2) \u003cstrong\u003eExtreme Hygroscopicity\u003c\/strong\u003e: LiBr is significantly more hygroscopic than LiCl. Upon even brief exposure to trace moisture, it quickly forms hydrates (LiBr *H2O). (3) \u003cstrong\u003eCrucial Dehydration Protocol\u003c\/strong\u003e: Commercial \"anhydrous\" LiBr often contains bound surface moisture. To prevent the irreversible formation of insulating lithium oxide (Li2O) or phase degradation during synthesis, LiBr should be dried under a deep vacuum (10^{-2} Torr or better) at 200°C to 300°C for 12–24 hours before weighing inside the glovebox.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 296.087px;\" 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\u003eCBSSEPCLB (C-BSSE-PC-LB)\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\u003e7550-35-8\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\u003e86.85 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;0.005 wt% (battery grade, anhydrous)\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\u003e1265 °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\u003e1.57 g\/mL at 25 °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;\"\u003ePackage Grade\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e50 g or 100 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: (1) Please store the LiBr 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\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2405829724005592\"\u003eP.
