{"product_id":"cbead3f","title":"D3F {1,3,5-trimethyl-1,3,5-tris­(3,3,3-trifluoropropyl) cyclotrisiloxane, TTC, \u003e99.0%} as Battery Electrolyte Additive, 25-100 g\/bottle, CBEAD3F","description":"\u003cp\u003eD3F (1,3,5-trimethyl-1,3,5-tris(3,3,3-trifluoropropyl) cyclotrisiloxane, C12H21F9O3Si3) is a specialized fluorosilicone cyclic trimer explored as a functional film-forming electrolyte additive for advanced lithium-ion batteries—particularly those utilizing high-nickel layered oxide cathodes and graphite or silicon-based anodes.   By combining a flexible siloxane (Si--O-Si) ring backbone with pendant trifluoropropyl groups, D3F is engineered to construct robust, hybrid protective interphases on both electrode surfaces.  \u003c\/p\u003e\n\u003cp\u003eThe key functional roles of D3F as battery electrolyte additive are shown below:\u003cstrong\u003e \u003c\/strong\u003e(1) \u003cstrong\u003eHybrid Interfacial Passivation (SEI\/CEI Formation)\u003c\/strong\u003e:\u003cstrong\u003e \u003c\/strong\u003eThe siloxane core and trifluoropropyl chains participate in preferential reductive and oxidative decomposition reactions prior to the bulk carbonate solvents.This yields a dual-functioning protective film comprising inorganic silicon-oxygen species, silicates, and fluorine-rich components (such as LiF), which effectively passivates the electrode interfaces. (2) \u003cstrong\u003eProtection of High-Voltage \/ Ni-Rich Cathodes\u003c\/strong\u003e: In cells operating at high upper cutoff voltages (~ 4.3-4.4 V), D3F helps build a stable Cathode Electrolyte Interphase (CEI) that mitigates parasitic electrolyte oxidation. By suppressing transition metal dissolution (such as manganese, cobalt, or nickel leaching from high-nickel oxides), it prevents those metal ions from migrating and poisoning the anode-side Solid Electrolyte Interphase. (3) \u003cstrong\u003eAnode Stabilization\u003c\/strong\u003e: The fluorinated alkyl chains assist in homogenizing ion flux across the graphite or silicon-carbon anode interface, preventing localized structural degradation and reducing continuous electrolyte consumption during prolonged cycling.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 275.725px;\" width=\"100%\"\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\u003eCBEAD3F (C-BEA-D3F)\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\u003e2374-14-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 119.725px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 119.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 119.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e12\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e21\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eSi\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\/CBEAD3F_Structure_100x100.jpg?v=1791317175\" 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\u003eWhite Solid (or Powder)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 10px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 10px;\"\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: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e468.54 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\u003e25 g, 50 g, and 100 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 try to store the D3F in a dry place (glovebox or dryroom is preferred)\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\/jacsat\/article-abstract\/147\/27\/23931\/3737685\/Designing-High-Temperature-Stable-Electrolytes?redirectedFrom=fulltext\"\u003e\u003cspan\u003eZ.
