{"product_id":"cbesbmimfsi","title":"[BMIM][FSI] {1-Butyl-3-methylimidazolium bis(fluorosulfonyl)imide, \u003e99.9%} Ionic Liquid as Battery Electrolyte Solvent, 25-100 g\/bottle, CBESBMIMFSI","description":"\u003cp\u003e[BMIM][FSI] (1-Butyl-3-methylimidazolium bis(fluorosulfonyl)imide) is a room-temperature ionic liquid (RTIL) that combines an aromatic, 5-membered imidazolium cation (bearing a butyl chain) with the highly mobile, flexible bis(fluorosulfonyl)imide (FSI) anion. By pairing the fast ion-transport kinetics and low viscosity of the FSI anion with the fluid dynamics of an imidazolium base, this formulation offers exceptional ionic conductivity. However, utilizing an imidazolium-based ionic liquid in battery systems introduces distinct electrochemical and interfacial trade-offs.\u003c\/p\u003e\n\u003cp\u003eThe key physicochemical \u0026amp; electrochemical characteristics are: (1) \u003cstrong\u003eExceptionally High Ionic Conductivity \u0026amp; Low Viscosity\u003c\/strong\u003e: Because the FSI anion possesses a small ionic radius, low molecular weight, and weak charge localization, and because the [BMIM] cation maintains low fluid friction, [BMIM][FSI] exhibits remarkably high ionic conductivity and low viscosity at ambient temperatures compared to bulkier pyrrolidinium or piperidinium imide systems. (2) \u003cstrong\u003eFavorable Anode Interfacial Chemistry\u003c\/strong\u003e: The FSI anion readily decomposes under cathodic polarization to form a stable, inorganic-rich Solid Electrolyte Interphase (SEI) containing lithium fluoride (LiF) and sulfur-oxygen species, assisting in interfacial stabilization. (3) \u003cstrong\u003eHigh Purity (\u0026gt;99.9%)\u003c\/strong\u003e: High-purity grades minimize residual halide ions (like chlorides) and trace moisture, which are critical for preventing premature corrosion or parasitic side reactions.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 352.8px;\"\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\u003eCBESBMIMFSI (C-BES-BMIMFSI)\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\u003e1235234-58-8\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 116px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 116px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 116px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e8\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e15\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eN\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eS\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\/CBESBMIMFSI_Structure_100x100.jpg?v=1791182771\" 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: 71.2px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 71.2px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 71.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9% (Battery Grade)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWater level: \u0026lt;200 ppm\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\u003e319.35 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\u003e1.36 g\/cm3\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 \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the [BMIM][FSI] ionic liquid in the dry 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\/full\/10.1002\/adfm.202001444\"\u003e\u003cspan\u003eS.
