{"product_id":"cbeapfp","title":"PFP (Pentafluoropyridine, \u003e99.0%) as Battery Electrolyte Additive, 25-100 g\/bottle, CBEAPFP","description":"\u003cp\u003ePFP (Pentafluoropyridine, C5F5N) is a highly electron-deficient, perfluorinated heteroaromatic compound evaluated as a specialized functional electrolyte additive for advanced lithium-ion and lithium-metal batteries. Featuring a pyridine ring completely substituted with fluorine atoms, PFP leverages strong electron-withdrawing inductive effects and specific ring-nitrogen coordination to stabilize electrode interfaces.\u003c\/p\u003e\n\u003cp\u003eThe key functional roles of PFP as battery electrolyte additive are shown below:\u003cstrong\u003e \u003c\/strong\u003e(1) \u003cstrong\u003ePreferential Reduction \u0026amp; Anode SEI Engineering\u003c\/strong\u003e: Because of the strongly electronegative fluorine atoms and the electron-deficient aromatic ring, PFP possesses a high reduction potential relative to standard carbonate solvents.It undergoes preferential electrochemical reduction during initial charging cycles, breaking down to help construct a dense, inorganic-rich Solid Electrolyte Interphase (SEI) containing lithium fluoride (LiF) and nitrogen-containing passivating species on graphite, silicon, or lithium-metal anodes. (2) \u003cstrong\u003eLewis Base Coordination \u0026amp; Anion Modulation\u003c\/strong\u003e: The ring nitrogen atom possesses a lone pair of electrons capable of mild coordination with Lewis acidic species (such as coordination centers or decomposition fragments from LiPF6), assisting in local solvation shell structuring and ionic dissociation. (3) \u003cstrong\u003eHigh-Voltage Cathode Compatibility (CEI Formation)\u003c\/strong\u003e: The fluorinated aromatic framework also participates in oxidative passivation on high-potential cathode surfaces, contributing to a stable Cathode Electrolyte Interphase (CEI) that minimizes transition metal dissolution and electrolyte oxidation at voltages ~ 4.3 V. \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 312.325px;\" 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\u003eCBEAPFP (C-BEA-PFP)\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\u003e700-16-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 130.725px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 130.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 130.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e5\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e5\u003c\/sub\u003e\u003cspan\u003eN\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\/CBEAPFP_Structure_100x100.jpg?v=1791353631\" 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\u003e169.05 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\u003cspan\u003e1.54 g\/mL at 25 °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\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\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the PFP 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.rsc.org\/ee\/article-abstract\/19\/18\/5980\/1297427\/Kinetic-coupling-derived-interphase-for-extreme\"\u003e\u003cspan\u003eM.
