{"product_id":"ccibescaotf","title":"Ca(OTf)2 (Calcium Trifluoromethanesulfonate, \u003e99.9%) Powder as Electrolyte Salt for Calcium-Ion Battery, 25-100 g\/bottle, CCIBESCaOTf","description":"\u003cp\u003eCalcium trifluoromethanesulfonate (commonly designated as Ca(OTf)2 or calcium triflate) is a high-purity metal-organic salt widely investigated as a primary electrolyte solute for rechargeable calcium-ion batteries (CIBs). By pairing a divalent calcium cation (Ca^{2+}) with charge-delocalized, hydrophobic trifluoromethanesulfonate (CF3SO3^-) anions, Ca(OTf)2 provides a conductive, halide-free alternative to traditional chloride- or perchlorate-based calcium salts.\u003c\/p\u003e\n\u003cp\u003eIts functional roles in electrolyte engineering are: (1) \u003cstrong\u003eDivalent Ion Transport \u0026amp; High Energy Density\u003c\/strong\u003e: As a divalent charge carrier, each calcium ion transfers two electrons per redox event, offering a pathway toward higher volumetric capacity compared to monovalent alkali systems (Li+, Na+). (2) \u003cstrong\u003eHalide-Free Corrosion Mitigation\u003c\/strong\u003e: Unlike corrosive calcium halide salts (CaCl2), which aggressively pit aluminum current collectors and degrade cell components, Ca(OTf)2 provides a non-chloride environment that drastically suppresses metal dissolution and premature pitting. (3) \u003cstrong\u003eAnion-Derived Interphase Passivation\u003c\/strong\u003e: During initial electrochemical cycling, the triflate anion participates in reductive decomposition at the electrode interface, assisting in the formation of a hybrid inorganic-organic Solid Electrolyte Interphase (SEI) containing fluorides and sulfites.\u003c\/p\u003e\n\u003cp\u003eIts primary electrochemical application domains are: (1) \u003cstrong\u003eRechargeable Calcium-Ion Batteries\u003c\/strong\u003e: Utilized in organic liquid and gel polymer electrolyte formulations to study reversible intercalation into transition metal oxides, sulfides, and specialized host materials. (2) \u003cstrong\u003eAlternative Anode Integration\u003c\/strong\u003e: Deployed in research aiming to overcome the high desolvation energy and passivation challenges associated with calcium metal deposition and stripping.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 309.2px;\" width=\"100%\"\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\u003eCCIBESCaOTf (C-CIB-ES-CaOTf)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 124px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 124px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 124px;\"\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\u003eCa\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\/CCIBESCaOTf_Structure_100x100.jpg?v=1790234240\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\n\u003cp\u003e55120-75-7\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\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\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9% (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\u003e338.22 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\u003eMelting Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e~350 °C (lit.)\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\u003eMoisture\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e\u0026lt;50 ppm\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;\"\u003e\u003cspan\u003e25 g, 50 g, and 100 g\/bottle\u003c\/span\u003e\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: Please store the Ca(OTf)2 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\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.202104639\"\u003eZ.
