{"product_id":"cazibeadotf","title":"DOTf {Dimethylformamidium Trifluoromethanesulfonate, \u003e98.0%} Powder as Electrolyte Additive for Aqueous Zinc Ion Battery, 5 g\/bottle, CAZIBEADOTf","description":"\u003cp\u003eDOTf (N,N-dimethylformamidium trifluoromethanesulfonate, HCON(CH3)2+CF3SO3^-) is a specialized, mildly acidic organic-inorganic hybrid salt used as an advanced electrolyte additive in high-performance aqueous zinc-ion batteries (AZIBs). Designed to target the solid electrolyte interphase (SEI) on zinc metal anodes, DOTf acts as a functional precursor that engineers a stable, protective passivation layer in-situ.\u003c\/p\u003e\n\u003cp\u003eThe key functions of DOTs are:\u003cstrong\u003e \u003c\/strong\u003e(1) \u003cstrong\u003eIn-Situ Generation of an Inorganic Protective SEI (ZnS Formation)\u003c\/strong\u003e: When introduced in minor amounts (typically 0.05 M to 0.1 M}) into standard aqueous zinc electrolytes (such as ZnSO4), DOTf provides controlled localized acidity. This mild proton activity facilitates the electrochemical reduction and decomposition of sulfate anions (SO4^{2-}), reacting locally with Zn^{2+} to construct an inorganic-rich zinc sulfide (ZnS) passivation layer on the zinc surface. (2) \u003cstrong\u003eMitigation of Dendrites and Side Reactions\u003c\/strong\u003e: The resulting ZnS-rich interphase acts as an artificial SEI that smooths out local electric field gradients, promotes uniform 2D horizontal zinc deposition, and successfully suppresses both zinc dendrite propagation and parasitic hydrogen evolution reactions (HER). (3) \u003cstrong\u003eSynergistic Triflate Anion Integration\u003c\/strong\u003e: The trifluoromethanesulfonate (OTf-) component assists in restructuring the primary solvation sheath of zinc ions near the inner Helmholtz layer, reducing free water activity at the electrode interface.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 194px;\"\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\u003eCAZIBEADOTf (C-AZIB-EA-DOTf)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 48px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 48px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 48px;\"\u003e\n\u003cp\u003eC₄H₈F₃NO₄S\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CAZIBEADOTf_Structure_100x100.png?v=1791694792\" 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\u003e705301-17-3\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\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;98.0%\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\u003e223.17 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 DOTf 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:\/\/www.cell.com\/joule\/fulltext\/S2542-4351(22)00184-2\"\u003e\u003cspan\u003eC.
