{"product_id":"cbeafppn","title":"FPPN (Pentafluoro(phenoxy)cyclotriphosphazene, \u003e99.0%) as Battery Electrolyte Additive, 5 g\/bottle, CBEAFPPN","description":"\u003cp\u003ePentafluoro(phenoxy)cyclotriphosphazene (commonly designated as FPPN) is a specialized heterocyclic organophosphorus compound engineered as a multifunctional electrolyte additive for advanced lithium-ion and sodium-ion batteries. Featuring a stable P3N3 cyclic phosphazene core substituted with five fluorine atoms and one electroactive phenoxy group, FPPN simultaneously delivers exceptional flame retardancy and dual-side interfacial stabilization.\u003c\/p\u003e\n\u003cp\u003eIts functional roles in electrolyte engineering are: (1) \u003cstrong\u003eSimultaneous SEI and CEI Passivation\u003c\/strong\u003e: Because of its tailored frontier orbital energy levels, FPPN undergoes sacrificial electrochemical reactions on both electrodes simultaneously during initial formation. It constructs uniform, ultrathin, inorganic-rich Solid Electrolyte Interphases (SEI) on anodes and Cathode Electrolyte Interphases (CEI) on positive electrodes. (2) \u003cstrong\u003eRobust Flame Retardancy \u0026amp; Thermal Safety\u003c\/strong\u003e: The high phosphorus, nitrogen, and fluorine content imparts powerful flame-suppressant characteristics. FPPN effectively quenches radical chain reactions during thermal abuse, significantly raising the self-extinguishing threshold and delaying exothermic decomposition. (3) \u003cstrong\u003eMitigation of Transition-Metal Dissolution\u003c\/strong\u003e: The nitrogen- and phosphorus-rich heterocyclic degradation products coordinate strongly with active transition metal sites on high-capacity oxide surfaces, suppressing catalytic side reactions and structural degradation.\u003c\/p\u003e\n\u003cp\u003eThe primary electrochemical domains are: (1) \u003cstrong\u003eHigh-Energy Sodium-Ion Batteries (SIBs)\u003c\/strong\u003e: Integrated into advanced carbonate or ester-based electrolytes to stabilize hard carbon anodes and layered oxide cathodes, supporting extended cycle stability and wide temperature operation in large-format pouch cells. (2) \u003cstrong\u003eHigh-Voltage Lithium-Ion Chemistries\u003c\/strong\u003e: Deployed alongside high-nickel layered oxide cathodes (such as NMC811) and silicon-containing composites to mitigate capacity fade, reduce gas evolution, and suppress thermal runaway risks under aggressive charging profiles\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 295.325px;\"\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\u003eCBEAFPPN (C-BEA-FPPN)\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\u003e33027-68-8\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 113.725px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 113.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 113.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e5\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e5\u003c\/sub\u003e\u003cspan\u003eN\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eOP\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\/CBEAFPPN_Structure_100x100.jpg?v=1790011130\" 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;99.0%\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: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e323.04 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\u003e5 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 FPPN liquid in the 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:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adma.202312287\"\u003eY.
