{"product_id":"cbesadtdl","title":"DTDL {2,2-Dimethoxy-4-(trifluoromethyl)-1,3-dioxolane, \u003e99.0%} as Battery Electrolyte Co-Solvent and Additive, 5-25 g\/bottle, CBESADTDL","description":"\u003cp\u003e2,2-Dimethoxy-4-(trifluoromethyl)-1,3-dioxolane (commonly designated as DTDL) is an advanced fluorinated cyclic ether solvent and electrolyte component. By incorporating a cyclic dioxolane backbone functionalized with an electron-withdrawing trifluoromethyl (-CF3) group and dual linear methoxy groups, DTDL bridges the gap between the high anodic stability of fluorinated media and the solvating performance required for high-energy lithium batteries.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of the DTDL are: (1) \u003cstrong\u003eSolvation Structure \u0026amp; Sheath Tuning\u003c\/strong\u003e: DTDL actively modifies the primary lithium-ion coordination shell. Its specific molecular geometry encourages contact ion pairs (CIPs) and aggregates (AGGs), suppressing solvent-separated ion pairing even at moderate salt concentrations. (2) \u003cstrong\u003eAnion-Derived Interphase (SEI\/CEI) Passivation\u003c\/strong\u003e: When paired with salts like lithium bis(fluorosulfonyl)imide (LiFSI), DTDL promotes the preferential decomposition of counter-anions on the anode surface. This generates a robust, inorganic-rich Solid Electrolyte Interphase (SEI) heavily enriched with lithium fluoride (LiF) that suppresses dendrite proliferation. (3) \u003cstrong\u003eHigh-Voltage Oxidative Resistance\u003c\/strong\u003e: The electron-withdrawing inductive effect of the -CF3 group lowers the Highest Occupied Molecular Orbital (HOMO) energy level, successfully preventing premature oxidative breakdown when operating against high-cutoff-voltage transition metal oxide cathodes.\u003c\/p\u003e\n\u003cp\u003eIts primary electrochemical domains are: (1) \u003cstrong\u003eHigh-Voltage Lithium-Metal Batteries (LMBs)\u003c\/strong\u003e: Utilized as a primary or co-solvent system to enable stable, long-term lithium stripping and plating, achieving high average Coulombic efficiencies (exceeding 99.2% over hundreds of cycles). (2) \u003cstrong\u003eAdvanced Full-Cell Configurations\u003c\/strong\u003e: Integrated into high-energy cells paired with nickel-rich layered oxide cathodes (such as LiNi0.8Co0.1Mn0.1O2 or NMC811) to mitigate transition-metal dissolution and maintain high-capacity retention under demanding cycling protocols.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 255.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.8802%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBESADTDL (C-BESA-DTDL)\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: 33.8802%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e2977166-74-6\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 74px;\"\u003e\n\u003ctd style=\"width: 33.8802%; height: 74px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 74px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e9\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e4\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\/CBESADTDL_Structure_100x100.jpg?v=1789942813\" 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: 33.8802%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; 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: 33.8802%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.0%\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: 33.8802%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 19.6px;\"\u003e\u003cspan\u003e202.13 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.8802%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 19.6px;\"\u003e\u003cspan\u003e5 g, 10 g, and 25 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 DTDL liquid in the dry place (glovebox is the best).\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.nature.com\/articles\/s41467-022-29199-3\"\u003e\u003cspan\u003eY.
