{"product_id":"cesailbmimtfsi","title":"[BMIM][TFSI] (1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, \u003e99.0%) Ionic Liquid as Electrolyte Solvent and Additive, CESAILBMIMTFSI","description":"\u003cp\u003e[BMIM][TFSI] (1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) is one of the most versatile and commercially popular hydrophobic ionic liquids in modern electrochemistry. It is prized for its combination of a wide electrochemical stability window, high thermal stability, and significantly lower viscosity compared to other [BMIM]-based salts like [BMIM][PF6].\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLithium-Ion and Lithium-Metal Batteries\u003c\/strong\u003e: [BMIM][TFSI] is used both as a co-solvent and a safety additive. (1) \u003cstrong\u003eFlame Retardancy\u003c\/strong\u003e: Even at 10–20% concentration in carbonate electrolytes, it drastically reduces flammability and vapor pressure, preventing \"thermal runaway.\" (2) \u003cstrong\u003eInterfacial Stability\u003c\/strong\u003e: It helps in the formation of a robust Solid Electrolyte Interphase (SEI). Unlike [EMIM]+ (which can exfoliate graphite), the bulkier [BMIM]+ cation is generally more compatible with carbon-based anodes when paired with appropriate film-forming additives like Vinylene Carbonate (VC). (3)\u003cstrong\u003e Lithium-Sulfur (Li-S) Batteries\u003c\/strong\u003e: It is a preferred solvent for Li-S systems because it has low polysulfide solubility, which helps suppress the \"shuttle effect\" that usually kills the cycle life of these batteries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCO2 Electroreduction (CO2RR)\u003c\/strong\u003e: In CO2 reduction, [BMIM][TFSI] is often used in gas-diffusion electrode (GDE) setups. (1) \u003cstrong\u003eWater Management\u003c\/strong\u003e: Its hydrophobic nature creates a \"water-lean\" interface. This is crucial for suppressing the competing Hydrogen Evolution Reaction (HER), allowing for much higher Faradaic Efficiencies toward Carbon Monoxide (CO) or Ethylene. (2) \u003cstrong\u003eCO2 Solubility\u003c\/strong\u003e: CO2 is significantly more soluble in [BMIM][TFSI] than in water, which helps overcome the mass-transport limitations that often restrict current density in aqueous cells.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupercapacitors (EDLCs)\u003c\/strong\u003e: It is a leading electrolyte for high-voltage supercapacitors. By moving from aqueous electrolytes to [BMIM][TFSI], the cell voltage can be increased from 1.2 V to 3.2 V. Because it doesn't freeze or boil easily, [BMIM][TFSI] allows supercapacitors to operate in extreme environments (e.g., -20°C to 100°C) where water-based systems would fail.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 373px;\"\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\u003eCESAILBMIMTFSI (C-ESA-ILBMIMTFSI)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAlso named as [BMIM][Tf2N]\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\u003e174899-83-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 154px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 154px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 154px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e10\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e15\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e6\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\/CESAILBMIMTFSI_molecular_structure_160x160.png?v=1771919739\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 55.2px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 55.2px;\"\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: 33.8px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 33.8px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 33.8px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.0% (Battery Grade)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWater level: \u0026lt;500 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\u003e419.36 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\u003e1.45 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 or 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][TFSI] 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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/en\/content\/articlehtml\/2024\/ta\/d4ta05906a\"\u003eH.
