{"product_id":"cbeafbsn","title":"FBSN {4-Fluoro-N,N- Dimethylbenzenesulfonamide, \u003e99.0%} as Battery Electrolyte Additive, 5-25 g\/bottle, CBEAFBSN","description":"\u003cp\u003e4-Fluoro-N,N-dimethylbenzenesulfonamide (commonly designated as FBSN) is a specialized functional organosulfur and fluorinated aromatic additive engineered for advanced lithium-ion batteries. By combining an electron-withdrawing fluorobenzene ring with a stable sulfonyl-amide (-SO2N(CH3)2) core, FBSN is tailored to address interfacial degradation and parasitic side reactions in high-voltage, nickel-rich cells.\u003c\/p\u003e\n\u003cp\u003eIts functional roles in electrolyte engineering are: (1) \u003cstrong\u003eInterfacial Passivation \u0026amp; CEI Stabilization\u003c\/strong\u003e: FBSN acts as a film-forming additive that participates in electrochemical reactions at the positive electrode surface. It assists in constructing a dense, robust Cathode Electrolyte Interphase (CEI) that suppresses continuous electrolyte oxidation and transition-metal dissolution. (2) \u003cstrong\u003eMitigation of Solvent Dehydrogenation\u003c\/strong\u003e: Studies on high-voltage and nickel-rich chemistries indicate that FBSN helps mitigate destructive solvent degradation pathways—such as suppressing the catalytic dehydrogenation of cyclic carbonates (like EC)—during prolonged cycling. (3) \u003cstrong\u003eEnhanced Structural Integrity\u003c\/strong\u003e: The decomposition products of FBSN contribute to a rigid, ionically conductive interphase layer that accommodates surface breathing and structural strain on high-capacity oxide cathodes.\u003c\/p\u003e\n\u003cp\u003eThe primary electrochemical domains are: (1) \u003cstrong\u003eHigh-Voltage Nickel-Rich Cells\u003c\/strong\u003e: Integrated into standard carbonate master electrolytes to support long-term cycling stability in cells paired with high-nickel layered oxide cathodes (e.g., NMC811) operating at upper voltage cutoffs exceeding 4.3 V. (2) \u003cstrong\u003eCapacity Retention and Impedance Suppression\u003c\/strong\u003e: Deployed to reduce polarization growth, mitigate gas evolution, and prevent rapid capacity fade under aggressive charging and high-temperature operating protocols.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 239.525px;\"\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\u003eCBEAFBSN (C-BEA-FBSN)\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\u003e383-31-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 57.925px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 57.925px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 57.925px;\"\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003eC\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003csub\u003e\u003cspan dir=\"auto\"\u003e8\u003c\/span\u003e\u003c\/sub\u003e\u003cspan dir=\"auto\"\u003e\u003cspan\u003e \u003c\/span\u003eH\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003csub\u003e\u003cspan dir=\"auto\"\u003e10\u003c\/span\u003e\u003c\/sub\u003e\u003cspan dir=\"auto\"\u003e\u003cspan\u003e \u003c\/span\u003eFNO\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003csub\u003e\u003cspan dir=\"auto\"\u003e2\u003c\/span\u003e\u003c\/sub\u003e\u003cspan dir=\"auto\"\u003e\u003cspan\u003e \u003c\/span\u003eS\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\/CBEAFBSN_Structure_100x100.jpg?v=1789978772\" 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\u003eWhite Powder\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\u003e203.23 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, 10 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 store the FBSN powder 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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1385894724026408\"\u003eY.
