It serves as the high-stability, non-flammable solvent into which a mobile metal salt is dissolved (e.g., LiTFSI, NaTFSI, or KTFSI) to create the working electrolyte.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLithium-Ion \u0026amp; Sodium-Ion Batteries\u003c\/strong\u003e: [EMIM][TFSI] is used as a co-solvent or additive to enhance safety and voltage. It is non-flammable and has negligible vapor pressure, acting as a flame retardant in standard carbonate electrolytes. It is highly stable at high potentials, making it suitable for high-voltage cathodes (e.g., LNMO). It should be noted that Imidazolium cations can intercalate into graphite anodes, potentially causing exfoliation. Therefore, it is often used with film-forming additives like VC (Vinylene Carbonate) or in \"solvent-in-salt\" configurations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCO2 Electroreduction (CO2RR)\u003c\/strong\u003e: While [EMIM][BF4] is more famous for CO2 reduction, [EMIM][TFSI] is used in non-aqueous CO2 reduction or as a hydrophobic additive. The [EMIM]+ cation stabilizes the CO2'- radical, lowering the overpotential for CO production. Moreover, it can be used to create a \"water-lean\" interface at the catalyst due to its hydrophobicity, which effectively suppresses the competing Hydrogen Evolution Reaction (HER).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupercapacitors\u003c\/strong\u003e: It is a premier choice for high-energy density supercapacitors. By replacing aqueous electrolytes with pure [EMIM][TFSI], the operating voltage can be pushed from 1.2V to 3.0 V. Since energy density scales with V^2, this leads to a massive increase in stored energy.\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\u003eCESAILEMIMTFSI (C-ESA-ILEMIMTFSI)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAlso named as [EMIM][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\u003e174899-82-2\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\u003eC8H11F6N3O4S2\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBESEMIMTFSI_molecular_structure_160x160.png?v=1765155612\"\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;99.5% (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\u003e391.31 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\u003e1.52 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\/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 [EMIM][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.acs.org\/doi\/abs\/10.1021\/acs.jpcb.2c02822\"\u003eH.
