{"product_id":"cbesg3","title":"Triglyme (Triethylene glycol dimethyl ether, G3, \u003e99.95%) Liquid as Battery Electrolyte Solvent, 100-500 g\/bottle, CBESG3","description":"\u003cp\u003eTriglyme (chemically known as triethylene glycol dimethyl ether or G3) is a high-boiling, acyclic polyether engineered as a premium solvent, chelating agent, and structural matrix for advanced lithium-metal, lithium-sulfur, and sodium-ion liquid electrolytes. By extending the ethylene glycol chain compared to shorter glymes (like monoglyme\/DME or diglyme\/G2), G3 provides unique solvation and thermal safety profiles tailored for high-performance electrochemical cells.\u003c\/p\u003e\n\u003cp\u003eIts functional roles in electrolyte engineering are: (1) \u003cstrong\u003eSolvation Shell Engineering (HCE \/ LHCE Systems)\u003c\/strong\u003e: G3 is a primary building block for High-Concentration Electrolytes (HCEs) and Localized High-Concentration Electrolytes (LHCEs). Its multi-ether backbone binds tightly to lithium or sodium ions, reducing free solvent activity and shifting reduction\/oxidation pathways toward beneficial anion-derived interphases. (2) \u003cstrong\u003eThermal Stability \u0026amp; Volatility Reduction\u003c\/strong\u003e: Unlike short-chain, highly volatile ethers (such as 1,3-dioxolane or dimethoxyethane), G3's significantly elevated boiling point (~216 °C) and low vapor pressure drastically suppress evaporation risks and enhance the overall thermal safety margin of the cell. (3) \u003cstrong\u003ePolysulfide Retention Management\u003c\/strong\u003e: In lithium-sulfur systems, its balanced solvent power helps regulate the dissolution and transport of intermediate polysulfides when paired with appropriate fluorinated diluents, mitigating the destructive shuttle effect.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 247.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBESG3 (C-BES-G3)\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: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e112-49-2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 46px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 46px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 46px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCH\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eO(CH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eCH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eO)\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eCH\u003c\/span\u003e\u003csub\u003e3\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\/CBESG3_Structure_100x100.jpg?v=1790089644\" 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: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; 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: 33.7019%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; 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: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e178.23 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7019%;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%;\"\u003e\u003cspan\u003e0.986 g\/mL at 25 °C (lit.)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003eBoling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e216 °C (lit.)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e100g, 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 \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please store the G3 liquid in the glovebox and process it with molecular sieve before use. \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\/S2405829724002290\"\u003e\u003cspan\u003eG.
