{"product_id":"cgpeiscotf","title":"Sc(OTf)3 {Scandium(III) Triflate, \u003e99.0%} as Initiator for Gel Polymer Electrolytes (GPEs) and Battery Electrolyte Additive, 5-25 g\/bottle, CGPEIScOTf","description":"\u003cp\u003eScandium(III) triflate [Sc(OTf)3, also called Scandium(III) Trifluoromethanesulfonate] is a highly active, water-tolerant Lewis acid catalyst and cationic polymerization initiator (Sc(CF3SO3)3). In advanced energy storage research, Sc(OTf)3 is utilized to drive the in situ cationic ring-opening polymerization (CROP) of multi-epoxy, cyclic ether, and oxetane crosslinking monomers (such as PEGE, PEGDE, and TMPTE) for Gel Polymer Electrolytes (GPEs), delivering rapid curing kinetics, superior thermal stability, and robust interfacial passivation in high-energy lithium, sodium, and metal-ion batteries.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of Sc(OTf)3 in GPEs are: (1) \u003cstrong\u003eInitiation of Cationic Ring-Opening Polymerization (CROP)\u003c\/strong\u003e: Sc(OTf)3 coordinates with the oxygen atoms of epoxide or cyclic ether monomers, polarizing the ring and rendering it susceptible to nucleophilic attack by adjacent monomers. This triggers rapid chain growth and crosslinking without generating gaseous byproducts or requiring external UV irradiation. (2) \u003cstrong\u003eRobust In Situ Gelation in Sealed Cells\u003c\/strong\u003e: Catalyzes uniform, controlled solidification of liquid precursor solutions infiltrating porous separator membranes (glass fiber, PE\/PP) and dense electrode microstructures at moderate thermal settings (55°C-70°C), completely eliminating free-flowing liquid electrolyte leakage. (3) \u003cstrong\u003eInterfacial Passivation \u0026amp; Ionic Transport Enhancement\u003c\/strong\u003e: The Lewis-acidic scandium sites and triflate anions actively interact with polar groups on polymer segments and lithium\/sodium salts, assisting in anion complexation, mitigating concentration polarization, and participating in the formation of a stable, inorganic-rich Solid Electrolyte Interphase (SEI) on metal anodes.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 395.113px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPEIScOTf (C-GPE-I-ScOTf)\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e144026-79-9\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 143.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 143.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 143.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eSc(SO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eCF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEIScOTf_structure_100x100.jpg?v=1793211372\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003eWhite Powder\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026gt;99.0%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 42.2625px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 42.2625px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 42.2625px;\"\u003e\n\u003cp\u003e\u003cspan\u003e492.16 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eMelting Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;300 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 31.125px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 31.125px;\"\u003e5 g, 10, and 25 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the Sc(OTf)3\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e in a dry place (glovebox is preferred).  \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\/abs\/pii\/S1385894724012427\"\u003eQ.
