{"product_id":"cbesdee","title":"DEE (1,2-Diethoxyethane, \u003e99.95%) Liquid as Battery Electrolyte Solvent, 100-500 g\/bottle, CBESDEE","description":"\u003cp\u003e1,2-Diethoxyethane (commonly designated as DEE or ethyl glyme) is a symmetric linear dialkyl ether engineered as an advanced high-performance electrolyte solvent, co-solvent, and solvation-sheath modifier for next-generation lithium-metal and sodium-metal batteries. By substituting the smaller methoxy groups of traditional 1,2-dimethoxyethane (DME) with bulkier ethoxy groups, DEE utilizes steric hindrance to fundamentally alter cation coordination chemistry without requiring complex fluorinated structures.\u003c\/p\u003e\n\u003cp\u003eThe functional roles of DEE in electrolyte engineering are: (1) \u003cstrong\u003eSteric-Effect Solvation Tuning\u003c\/strong\u003e: DEE’s bulky ethoxy architecture discourages solvent-dominated coordination sheaths. Even at moderate or standard salt concentrations (e.g., 1 M to 4 M LiFSI), it induces an anion-rich inner solvation shell, bypassing the high-concentration requirements typically needed to drive contact ion pair formation. (2) \u003cstrong\u003eRobust Anion-Derived Interphase (SEI\/CEI) Formation\u003c\/strong\u003e: Because the primary coordination sphere is rich in anions (FSI-), DEE-based electrolytes promote the preferential decomposition of counter-anions during early-stage cycling. This yields a dense, inorganic-rich Solid Electrolyte Interphase (SEI) heavily enriched with lithium or sodium fluoride (LiF \/ NaF) that suppresses dendrite proliferation.  (3) \u003cstrong\u003eEnhanced High-Voltage Oxidative Stability\u003c\/strong\u003e: The altered solvation structure and elevated LUMO\/HOMO stability thresholds prevent premature electrolyte breakdown, allowing stable operation above 4.3 V–4.4 V against high-nickel layered oxide cathodes without relying on expensive fluorinated co-solvents. (4) \u003cstrong\u003eImproved Thermal Safety Margin\u003c\/strong\u003e: Offering a substantially wider thermal window than standard DME (which features a hazardous flash point of -2 °C), DEE's higher boiling point (~121 °C) and safer flash point (~35 °C) heavily reduce volatility and flammability hazards during storage and cell assembly.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 283.2px;\"\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\u003eCBESDEE (C-BES-DEE)\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\u003e629-14-1\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 82px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 82px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 82px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e1\u003c\/sub\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBESDEE_Structure_100x100.jpg?v=1789964321\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\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\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; 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: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.95% (Battery Grade, Anhydrous)\u003c\/span\u003e\u003cspan\u003e\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\u003e118.18 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\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e100 g, 200 g, and 500 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 DEE liquid a dry place (glovebox is the best option).\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:\/\/www.nature.com\/articles\/s41560-021-00962-y\"\u003eZ.
