{"product_id":"cbesatfp","title":"TFP (Tris(2,2,2-trifluoroethyl)phosphate, \u003e99.8%) as Battery Electrolyte Co-Solvent and Additive, 10-50 g\/bottle, CBESATFP","description":"\u003cp\u003eTris(2,2,2-trifluoroethyl) Phosphate (TFP)—frequently abbreviated as TTFP or TFPa—is a fluorinated organophosphorus compound widely deployed as a flame-retardant co-solvent\/additive and high-voltage interphase modifier in non-aqueous electrolytes for lithium-ion, lithium-metal, and sodium-ion batteries. The core functional roles \u0026amp; electrochemical advantages are shown below:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNon-Flammability \u0026amp; Thermal Safety Enhancement\u003c\/strong\u003e: Unlike non-fluorinated alkyl phosphates (e.g., trimethyl phosphate\/TMP or triethyl phosphate\/TEP) which suffer from severe graphite anode incompatibility, TFP combines the radical-scavenging flame retardancy of the phosphate core (PO4^{3-}) with the electrochemical stability of trifluoroethyl groups. It scavenges active H* and OH* free radicals in the vapor phase, significantly reducing self-extinguishing time (SET) and eliminating electrolyte flash points when incorporated at 5 wt% to 20 vol%.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Oxidation Stability for High-Voltage Cathodes\u003c\/strong\u003e: The three strongly electron-withdrawing -CF3 groups lower TFP’s Highest Occupied Molecular Orbital (HOMO) energy level. TFP demonstrates high anodic oxidation tolerance (\u0026gt;4.8 V vs. Li\/Li+), resisting solvent breakdown on nickel-rich NMC (e.g., NMC811), high-voltage LiCoO2 (LCO), and cobalt-free high-voltage spinels (LiNi0.5Mn1.5O4).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInorganic Fluorine-Rich Interphase (SEI \u0026amp; CEI)\u003c\/strong\u003e: Sacrificial decomposition of TFP under extreme potentials yields an inorganic-rich interphase dominated by lithium fluoride (LiF) and lithium phosphate (LixPOyFz) species. This dense, highly ionically conductive layer passivates active cathode surface sites (suppressing transition-metal dissolution) and promotes uniform Li+ flux across alkali-metal anodes to inhibit dendrites.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeak Solvation \/ LHCE Diluent Behavior\u003c\/strong\u003e: The electron-withdrawing fluorinated chains reduce the donor power of the phosphate oxygen (P=O). In Localized High-Concentration Electrolytes (LHCEs), TFP can act as a fluorinated diluent that lowers bulk viscosity without disrupting contact ion pairs (CIPs) or aggregate (AGG) structures formed between solvating solvents and lithium salts (LiFSI or LiPF6).\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 321.6px;\" 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\u003eCBESATFP (C-BESA-TFP)\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\u003e358-63-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 140px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 140px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 140px;\"\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\u003eF\u003c\/span\u003e\u003csub\u003e9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eP\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\/CBESATFP_02_100x100.jpg?v=1786175405\" 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;99.8% (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\u003e344.07 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, 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 try to store the TFP liquid in a dry place (glovebox is the best)\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\/aaemcq\/article-abstract\/4\/5\/4919\/411792\/Tris-2-2-2-trifluoroethyl-Phosphate-as-a-Cosolvent?redirectedFrom=fulltext\"\u003eY.
