{"product_id":"cscsedl3702","title":"Specific Electrolyte for Supercapacitor {3 V, -40℃~65℃}, 200 g\/bottle, CSCSEDL3702","description":"\u003cp\u003eDesigning a supercapacitor (Electric Double-Layer Capacitor, EDLC) capable of a 3.0 V operating window across an extreme temperature range of -40 ℃ to +65 ℃ requires moving away from standard acetonitrile (which struggles with high-temperature vapor pressure\/safety at 65℃) and pure ionic liquids (which freeze or suffer massive viscosity spikes at -40 ℃).The optimal strategy involves a co-solvent organic formulation or a solvent-plasticized ionic liquid engineered to maintain high ionic conductivity at sub-zero temperatures while resisting oxidative decomposition at 3.0 V and +65 ℃.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.0 M Tetraethylammonium tetrafluoroborate (TEABF4) or 1.0 M Triethylmethylammonium spiro-bis(pyrrolidinium) tetrafluoroborate ({TEMABF4). TEABF4 is the industry standard for high-voltage carbon-based supercapacitors. It offers exceptional electrochemical stability up to and beyond 3.0 V when paired with high-surface-area activated carbon electrodes, alongside high thermal decomposition thresholds. (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 = 3 : 7 to 4 : 6 by volume. Pure acetonitrile provides the ultra-low viscosity and high conductivity required to reach -40 ℃ without freezing, but it has a high vapor pressure at 65 ℃. Pure propylene carbonate extends the high-temperature safety and boiling point, but is too viscous at -40 ℃. Blending them creates a synergistic medium that suppresses freezing points, maintains low Equivalent Series Resistance (ESR) at -40 ℃, and remains stable against gas generation or boiling at +65℃ under a 3.0 V load.\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\u003eCSCSEDL3702 (C-SC-SE-DL3702)\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;100 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\u003e3 V, -40℃~65℃\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:\/\/pubs.acs.org\/enfuem\/article-abstract\/38\/10\/8528\/637538\/A-Comprehensive-Review-of-Novel-Emerging?redirectedFrom=fulltext\"\u003e\u003cspan\u003eMoumita Saha, et al.
