{"product_id":"cgpeisnotf","title":"Sn(OTf)2 {Tin(III) Triflate, \u003e99.0%} as Initiator for Gel Polymer Electrolytes (GPEs), 10-50 g\/bottle, CGPEISnOTf","description":"\u003cp\u003eTin(II) trifluoromethanesulfonate [Sn(OTf)2]—commonly referred to as tin(II) triflate (Sn(CF3SO3)2)—is a highly active Lewis acid catalyst and cationic polymerization initiator. In advanced energy storage research, Sn(OTf)2 is widely utilized to drive the in situ ring-opening polymerization of cyclic ether solvents (such as 1,3-dioxolane [DOL]) and multi-epoxy\/ether crosslinking precursors for Gel Polymer Electrolytes (GPEs) and quasi-solid-state sodium and lithium metal batteries. Beyond its catalytic function, Sn^{2+} species actively participate in electrochemical reduction processes to engineer robust, hybrid protective interphases on alkali metal anodes.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of Sn(OTf)2 in GPEs are: (1) \u003cstrong\u003eInitiation of Cationic Ring-Opening Polymerization (CROP)\u003c\/strong\u003e: Sn(OTf)2 coordinates with cyclic ether monomers (such as DOL), activating the ring structure toward nucleophilic attack. This triggers spontaneous chain propagation to convert liquid precursors into a dimensionally stable poly(ether)-based quasi-solid gel network. (2) \u003cstrong\u003eIn Situ Formation of Hybrid SEI Passivation Layers\u003c\/strong\u003e: During initial cell formation cycles, cathodic reduction of Sn^{2+} yields a uniform metal-tin alloy and inorganic-rich Solid Electrolyte Interphase (SEI). This hybrid layer homogenizes local ionic flux, suppresses parasitic side reactions, and mitigates dendrite penetration during extended high-rate cycling.   (3) \u003cstrong\u003eElimination of Interfacial Resistance\u003c\/strong\u003e: The low-viscosity liquid precursor thoroughly infiltrates porous separators and dense electrode microstructures before setting. Upon in situ polymerization, it establishes intimate interfacial contact, drastically reducing boundary resistance.\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\u003eCGPEISnOTf (C-GPE-I-SnOTf)\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\u003e62086-04-8\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\u003e(CF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eSO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eSn\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEISnOTf_structure_100x100.jpg?v=1793213016\" 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\u003e416.84 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≥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;\"\u003e10 g, 20, and 50 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 Sn(OTf)2\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\/S2352152X24032791\"\u003eH.
