{"product_id":"cgpefrmdevp","title":"DEVP {Diethyl Vinylphosphonate, \u003e99.0%} as Flame-Retardant Monomer for Gel Polymer Electrolyte, 5-20 g\/bottle, CGPEFRMDEVP","description":"\u003cp\u003eDiethyl vinylphosphonate (DEVP) is a specialized organophosphorus monomer (C6H13O3P) featuring a polymerizable vinyl (CH2=CH-) group directly bonded to a dialkyl phosphonate (-P(=O)(OC2H5)2) moiety. In advanced energy storage research, DEVP is utilized as a dual-function, reactive flame-retardant co-monomer for Gel Polymer Electrolytes (GPEs). By copolymerizing directly into the 3D polymer network, it permanently anchors phosphorus into the gel matrix, drastically suppressing electrolyte flammability while contributing to stable interfacial passivation in high-safety lithium and sodium metal batteries.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of DEVP monomer in GPEs are: (1) \u003cstrong\u003eActive Suppression of Electrolyte Flammability\u003c\/strong\u003e: By immobilizing high concentrations of phosphorus directly within the gel polymer network, DEVP effectively raises the flash point of the liquid electrolyte plasticizer and terminates radical chain reactions during thermal runaway, preventing sustained ignition. (2) \u003cstrong\u003eInterfacial Passivation (SEI\/CEI Enhancement)\u003c\/strong\u003e: The phosphonate functionality participates in electrochemical reduction and oxidation processes during initial formation cycles, contributing to the formation of a robust, inorganic-rich Solid Electrolyte Interphase (SEI) on anodes and Cathode Electrolyte Interphase (CEI) on high-voltage cathodes. (3) \u003cstrong\u003eCopolymerization with Crosslinking Networks\u003c\/strong\u003e: Because DEVP possesses a reactive vinyl group, it readily copolymerizes alongside multi-functional crosslinkers (such as PEGDA, TMPTA, or TMPTMA) or via thiol-ene click chemistry, ensuring that the flame-retardant segments are uniformly distributed throughout the 3D gel mesh rather than acting as inert fillers.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 352.587px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPEFRMDEVP (C-GPE-FRM-DEVP)\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e682-30-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 123.475px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 123.475px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 123.475px;\"\u003e\n\u003cp\u003eCH₂=CHPO(OCH₂CH₃)₂\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEFRMDEVP_structure_160x160.jpg?v=1793080088\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 42.2625px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 42.2625px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 42.2625px;\"\u003e\n\u003cp\u003eColorless to light-yellow clear liquid\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 42.2625px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 42.2625px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 42.2625px;\"\u003e\n\u003cp\u003e\u003cspan\u003e164.14 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 42.2625px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 42.2625px;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 42.2625px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1.068 g\/mL at 25 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eBoling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e1.068 g\/mL at 25 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eFlash Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e110 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 31.125px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 31.125px;\"\u003e5 g, 10, and 20 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 try to store the DEVP\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e monomer in a dry and dark place.  \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:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.202409836\"\u003e\u003cspan\u003eZ.
