{"product_id":"cbeabstfa","title":"BSTFA (N,O-Bis(trimethylsilyl)trifluoroacetamide, BSA or NOB, \u003e99.0%) as Battery Electrolyte Additive, 25-100 g\/bottle, CBEABSTFA","description":"\u003cp\u003eN,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA)—frequently referenced in electrochemical research as a functional electrolyte additive—has drawn attention for its ability to stabilize high-energy electrode interfaces, particularly for lithium and sodium-based batteries. \u003c\/p\u003e\n\u003cp\u003eThe main features of BSTFA in electrolyte engineering are: (1) \u003cstrong\u003eTailored SEI Passivation Layer\u003c\/strong\u003e: BSTFA preferentially reduces on the surface of reactive anodes (such as lithium metal) ahead of bulk electrolyte solvents. This reductive decomposition constructs a robust, hybrid solid electrolyte interphase (SEI) rich in inorganic and organosilicon components like LiF, Li3N, and SiOx. (2) \u003cstrong\u003eDendrite Suppression\u003c\/strong\u003e: The resulting inorganic-rich passivation layer regulates local Li+ flux, mitigating continuous electrolyte consumption and promoting uniform, dendrite-free metal deposition. (3) \u003cstrong\u003eElectrochemical Polymerization\u003c\/strong\u003e: Due to its unsaturated molecular structure and functional groups, BSTFA-derived radical cations can participate in interfacial polymerization processes alongside carbonate co-solvents, improving the elasticity and structural integrity of the protective film. (4) \u003cstrong\u003eScavenging Impurities\u003c\/strong\u003e: Organosilicon compounds structurally related to BSTFA inherently act as effective moisture and trace-HF scavengers, protecting lithium salts (like LiPF6) from destructive hydrolysis pathways.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 319.8px;\" 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\u003eCBEABSTFA (C-BEA-BSTFA)\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\u003e25561-30-2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 99px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 99px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 99px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e8\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e18\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eNOSi\u003c\/span\u003e\u003csub\u003e2\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\/CBEABSTFA_Structure_100x100.jpg?v=1790568128\" 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% (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\u003e257.40 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\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e0.969 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\u003e Boling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e45-50 °C\/14 mmHg (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 store the BSTFA liquid in a dry place (glovebox is the best option).\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\/S2405829721003585\"\u003eR.
