{"product_id":"cscsedl3611","title":"Specific Electrolyte for Supercapacitor {2.7 V, -40℃~70℃}, 200 g\/bottle, CSCSEDL3611","description":"\u003cp\u003eDesigning an electric double-layer capacitor (EDLC) or supercapacitor operating at a standard 2.7 V window across an extended temperature range of -40 ℃ to +70 ℃ requires balancing sub-zero ionic conductivity with high-temperature thermal stability and vapor-pressure suppression. While 2.7 V is less demanding on oxidative stability than 3.0 V systems, reaching +70 ℃ means pure low-boiling solvents (like neat acetonitrile) can generate excessive internal vapor pressure and risk cell bulging. Conversely, pure high-boiling solvents (like propylene carbonate) freeze or become too viscous at -40 ℃. A balanced binary co-solvent approach resolves this trade-off.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.2 M Tetraethylammonium tetrafluoroborate (TEABF4). The TEABF4 is the industry standard for carbon-based EDLCs. It offers excellent dissociation, high ionic conductivity, and exceptional electrochemical stability up to and beyond 2.7 V without undergoing reductive or oxidative breakdown on high-surface-area activated carbon electrodes. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: (i) \u003cem\u003eCore Solvents\u003c\/em\u003e: Propylene Carbonate (PC) + Acetonitrile (AN) mixed at a volumetric ratio of PC : AN = 1 : 1 to 2 : 3 by volume. Acetonitrile (AN) provides the low viscosity and low freezing point necessary to maintain high ionic conductivity and low Equivalent Series Resistance (ESR) down to -40 ℃. Propylene Carbonate (PC) features a high boiling point (~242 °C) and suppresses the high-temperature vapor pressure of AN, ensuring structural safety and preventing dry-up or gas generation during continuous operation at +70 ℃.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 272.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSEDL3611 (C-SC-SE-DL3611)\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: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; 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: 74.8px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 74.8px;\"\u003e\u003cem\u003eElectrolyte Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 74.8px;\"\u003e\n\u003cp\u003eUndisclosed recipe from leading manufacturer that has been well demonstrated in pilot-scale supercapacitor project. \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eHumidity Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;20 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eAcid Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;50 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003ePerformance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e2.7 V, -40℃~70℃\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 19.6px;\"\u003e\u003cspan\u003e200 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 specific supercapacitor electrolyte in the glovebox due to its sensitivity to humidity.\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:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/batt.202000314\"\u003e\u003cspan\u003eF.
