{"product_id":"clibearbotf","title":"RbOTf {[Rubidium Triflate], \u003e99.95%} Powder as Electrolyte Additive for Lithium-Ion Battery, 10-50 g\/bottle, CLIBEARbOTf","description":"\u003cp\u003eRubidium Triflate (RbOTf}, or Rubidium trifluoromethanesulfonate, RbCF3SO3) is an alkali metal salt functional additive evaluated in non-aqueous electrolytes for advanced rechargeable batteries.  While closely related to RbTFSI, RbOTf combines the large Rb+ cation with a smaller, rigid triflate anion (CF3SO3^-) rather than the bulkier, flexible imide anion (TFSI-).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelf-Healing Electrostatic Shield (SHES)\u003c\/strong\u003e: Like other heavy alkali cations (Cs+, Rb+), Rb+ operates through an electrostatic shielding mechanism on lithium-metal anodes: The reduction potential of Rb+ (~ -2.93 V vs. SHE) is slightly less negative than that of Li+ (~ -3.04 V). At high local current densities (e.g., emerging dendrite tips), accumulated Rb+ ions create a localized positive electric field without being reduced into metallic rubidium. This electrostatically repels incoming Li+ ions to adjacent flat areas, forcing smooth, planar lithium deposition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTriflate-Derived Interphase Construction\u003c\/strong\u003e: The triflate anion (OTf-) exhibits distinct decomposition characteristics on anode and cathode surfaces: Under reductive conditions at the lithium anode, OTf- breaks down to form an inorganic-rich Solid Electrolyte Interphase (SEI) composed of lithium fluoride (LiF) and sulfur species (Li2S). This layer offers high mechanical strength and fast Li+ interfacial transport. Unlike imide salts (TFSI-), which can cause aluminum current collector pitting at higher potentials (\u0026gt; 3.8 V), triflate species are generally less corrosive toward aluminum, providing better high-voltage current collector stability.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 261px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLIBEARbOTf (C-LIB-EA-RbOTf)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 115px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 115px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 115px;\"\u003e\n\u003cp\u003eRbSO₃CF₃\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBEARbOTf_02_100x100.jpg?v=1785740980\" 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: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite Powder\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: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.95% (Battery Grade)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e234.53 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e10 g, 25 g, 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 store the RbOTf powder in the glovebox due to its sensitivity to humidity and oxygen\u003c\/span\u003e\u003cspan\u003e \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\n\u003ca href=\"https:\/\/pubs.rsc.org\/eb\/article\/doi\/10.1039\/d6eb00050a\/1244564\/Secondary-alkali-metal-salts-in-supporting\"\u003e\u003cspan\u003eT.
