{"product_id":"cscsedl3413","title":"Specific Electrolyte for Supercapacitor {2.85-3.0 V, -40℃~80℃}, 200 g\/bottle, CSCSEDL3413","description":"\u003cp\u003eDesigning a supercapacitor (Electric Double-Layer Capacitor, EDLC) operating at an aggressive voltage window of 2.85 V to 3.0 V across a wide thermal range of -40 ℃ to +80℃ pushes traditional organic electrolyte formulations to their absolute limits. At +80 ℃ combined with 3.0 V, standard acetonitrile-based electrolytes suffer from extreme vapor pressure and accelerated electrolyte oxidation, while pure high-boiling solvents freeze or cause sharp internal resistance (ESR) spikes at -40 ℃. To survive this environment, the formulation must employ an advanced salt and a high-boiling binary co-solvent system engineered to suppress both low-temperature viscosity barriers and high-temperature gas generation.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.0 M Triethylmethylammonium spiro-bis(pyrrolidinium) tetrafluoroborate (TEMABF4) or 1.0 M Spiro-(1,1'-bipyrrolidine) tetrafluoroborate (SBPBF4). While standard TEABF4 can begin to show oxidative degradation or Hofmann-type elimination side-reactions at 3.0 V and +80 ℃, quaternary spirocyclic ammonium salts like SBPBF4 or TEMABF4 possess superior anodic stability windows (stable past 3.2 V vs. carbon) and higher thermal decomposition thresholds, preventing calendar-life fade at +80 ℃. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: (i) \u003cem\u003eCore Solvents\u003c\/em\u003e: Propylene Carbonate (PC) + y-Butyrolactone (GBL) mixed at a volumetric ratio of PC : GBL = 3 : 7 to 4 : 6 by volume. y-Butyrolactone (GBL) has a low melting point and low viscosity, ensuring that ion transport remains active and Equivalent Series Resistance (ESR) is kept within bounds down to -40 ℃. Propylene Carbonate (PC) provides a high boiling point (~242 °C) and excellent anodic stability. Together, this non-acetonitrile blend eliminates the dangerous vapor pressure build-up that pure low-boiling nitriles would experience at +80 ℃.\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\u003eCSCSEDL3413 (C-SC-SE-DL3413)\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\u003e2.85-3.0 V, -40℃~80℃\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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S2211285512002303\"\u003e\u003cspan\u003eW.
