{"product_id":"cesailbmimpf6","title":"[BMIM][PF6] (1-Butyl-3-methylimidazolium hexafluorophosphate, \u003e99.0%) Ionic Liquid as Electrolyte Solvent and Additive, 25 or 100 g\/bottle, CESAILBMIMPF6","description":"\u003cp\u003eBMIMPF6 (1-Butyl-3-methylimidazolium hexafluorophosphate) is a popular and widely studied example of an ionic liquid (IL) used as an electrolyte component in various electrochemical devices, particularly batteries and supercapacitors. It serves as the high-stability, non-flammable solvent into which a mobile metal salt is dissolved (e.g., LiPF6, LiTFSI, NaTFSI, or KTFSI) to create the working electrolyte.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLithium-Ion Batteries (LIB) Additive\u003c\/strong\u003e: Used in small concentrations (1–5 wt%) as a functional additive. It can also significantly reduces the flammability of standard carbonate electrolytes, acting as a safety \"buffer\". Some studies show that 5% [BMIM][PF6] in a binary electrolyte improves capacity retention in LiFePO4 batteries by stabilizing the electrode-electrolyte interface.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCO2 Electroreduction (CO2RR)\u003c\/strong\u003e: Like other imidazolium ionic liquids, [BMIM][PF6] acts as a co-catalyst for CO2 reduction. (1) \u003cstrong\u003eIntermediate Stabilization\u003c\/strong\u003e: The [BMIM]+ cation adsorbs onto catalysts (like Silver or Gold) and stabilizes the energy-intensive CO2'- radical intermediate. It is highly effective at steering the reaction toward Carbon Monoxide (CO) while suppressing the competing Hydrogen Evolution Reaction (HER). Its hydrophobic nature helps repel water from the electrode, further starving the HER.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupercapacitors:\u003c\/strong\u003e [BMIM][PF6] is a popular electrolyte for high-energy density supercapacitors. While aqueous capacitors are limited to 1.2 V, [BMIM][PF6] can operate up to 3.0 V. The bulky [BMIM]+ and [PF6]- ions form a thick electric double layer (EDL). Research shows that the larger anion size compared to BF4- can actually enhance capacitance at high voltages.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 371.6px;\"\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\u003eCESAILBMIMPF6 (C-ESA-ILBMIMPF6)\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\u003e174501-64-5\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 196px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 196px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 196px;\"\u003e\n\u003cp\u003eC8H15F6N2P\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBESBMIMPF6_molecular_structure_160x160.png?v=1765247558\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 10px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 10px;\"\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\u003e284.18 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\u003e1.38 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 BMIMPF6 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\/articlelanding\/2013\/cp\/c3cp51218e\/unauth\"\u003eZ.
