{"product_id":"cbeattfb","title":"TFEB (Tris(2,2,2-trifluoroethyl)borate, TTFEB, \u003e99.0%) as Battery Electrolyte Additive, 10-25 g\/bottle, CBEATTFB","description":"\u003cp\u003eTFEB (Tris(2,2,2-trifluoroethyl) borate, frequently abbreviated as TTFEB, B(OCH2CF3)3) is an advanced organoborate compound engineered as a functional electrolyte additive for high-performance lithium-ion and lithium-metal batteries. By pairing a central electron-deficient boron atom with heavily fluorinated alkoxy groups, TFEB provides targeted interfacial stabilization, particularly under high-voltage and elevated-temperature conditions.   \u003c\/p\u003e\n\u003cp\u003eThe key functional roles of TFEB as battery electrolyte additive are shown below:\u003cstrong\u003e \u003c\/strong\u003e(1) \u003cstrong\u003eCathode Electrolyte Interphase (CEI) Formation\u003c\/strong\u003e:\u003cstrong\u003e \u003c\/strong\u003eTFEB preferentially undergoes electrochemical oxidation on high-potential cathode surfaces before bulk carbonate solvents decompose. This yields a stable, protective passivating film that prevents direct contact between the active material and the liquid electrolyte, suppressing transition-metal dissolution (e.g., manganese or cobalt leaching). (2) \u003cstrong\u003eLewis Acid \/ Anion Receptor Behavior\u003c\/strong\u003e: The central boron atom functions as a Lewis acid and effective anion receptor. It coordinates with degradation byproducts (such as fluoride ions or trace nucleophiles generated from LiPF6 hydrolysis), mitigating destructive side reactions. (3) \u003cstrong\u003eImpurities and HF Scavenging\u003c\/strong\u003e: By chemically trapping trace moisture and acidic species like hydrofluoric acid (HF), TFEB protects the current collectors and prevents acid-catalyzed destruction of the active cathode structure. (4) \u003cstrong\u003eAnode Interphase Enhancement\u003c\/strong\u003e: The fluorinated ethyl groups assist in contributing inorganic fluoride components (such as LiF) to the Solid Electrolyte Interphase (SEI) on graphite or lithium-metal anodes, promoting more uniform ion flux and suppressing dendritic growth.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 254.6px;\" 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\u003eCBEATTFB (C-BEA-TTTFB)\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\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e659-18-7\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 73px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 73px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 73px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eBF\u003c\/span\u003e\u003csub\u003e9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEATTFB_Structure_100x100.jpg?v=1791312455\" 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\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: 33.6331%; 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;99.0%\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\u003e307.91 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;\"\u003e\u003cspan\u003e10 g and 25 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 try to store the TFEB liquid in a dry place (glovebox or dryroom 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\u003ca href=\"https:\/\/pubs.acs.org\/jacsat\/article-abstract\/147\/27\/23931\/3737685\/Designing-High-Temperature-Stable-Electrolytes?redirectedFrom=fulltext\"\u003e\u003cspan\u003eZ.
