{"product_id":"cbesadmtfa","title":"DMTFA (N,N-Dimethyltrifluoroacetamide, \u003e99.5%) as Battery Electrolyte Co-Solvent and Additive, 10-50 g\/bottle, CBESADMTFA","description":"\u003cp\u003eN,N-Dimethyltrifluoroacetamide (commonly designated as DMTFA) is a specialized fluorinated amide compound engineered for advanced energy storage systems. By pairing a strongly electron-withdrawing trifluoromethyl group with a polar dimethylamide backbone, DMTFA functions as a high-permittivity co-solvent, solvation-sheath modifier, and functional interphase-directing additive for high-voltage lithium-ion, lithium-metal, and sodium-ion batteries.\u003c\/p\u003e\n\u003cp\u003eIts main functional roles in electrolyte engineering are: (1) \u003cstrong\u003eSolvation Sheath Engineering\u003c\/strong\u003e: DMTFA actively participates in the primary solvation shell of lithium or sodium ions. Because of its strong donor number coupled with the electron-withdrawing inductive effect of the -CF3 group, it facilitates anion incorporation into the inner solvation sheath, encouraging anion-derived interphase formation. (2) \u003cstrong\u003eRobust Interphase (SEI\/CEI) Passivation\u003c\/strong\u003e: During initial electrochemical reduction and oxidation, DMTFA decomposes to help construct a hybrid, inorganic-organic protective film. This interphase is enriched with metal fluorides (LiF \/ NaF) alongside nitrogen-containing decomposition species, which collectively suppress continuous electrolyte consumption and dendrite growth. (3) \u003cstrong\u003eHigh-Voltage Oxidative Stability\u003c\/strong\u003e: The electron-withdrawing fluorinated tail deactivates the amide nitrogen and carbonyl oxygen against premature electrophilic attack, raising the anodic stability threshold to support high-voltage cathode operation (\u0026gt;4.3 V).\u003c\/p\u003e\n\u003cp\u003eIts main electrochemical applications are: (1) \u003cstrong\u003eHigh-Voltage Lithium-Ion Systems\u003c\/strong\u003e: Integrated into master formulations paired with high-nickel layered oxides (e.g., NMC811) to minimize transition-metal dissolution and reduce gassing during high-temperature cycling. (2) \u003cstrong\u003eLithium-Metal and Sodium-Metal Anodes\u003c\/strong\u003e: Assists in stabilizing highly reactive alkali metal surfaces by establishing a dense, uniform, and ionically conductive passivation layer.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 283.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBESADMTFA (C-BESA-DMTFA)\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: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1547-87-1\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 102px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 102px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 102px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eNO\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\/CBESADMTFA_Structure_100x100.jpg?v=1789841216\" 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: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eColorless Liquid\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: 33.7019%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.5% (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: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e141.09 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e10 g, 25 g, and 50 g\/bottle\u003c\/span\u003e\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 DMTFA 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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.acs.org\/aamick\/article-abstract\/9\/25\/21307\/703956\/Enhanced-Cycle-Stability-of-Rechargeable-Li-O2?redirectedFrom=fulltext\"\u003eE.
