{"product_id":"cbeaes","title":"ES (Ethylene Sulfite, \u003e99.0%) as Battery Electrolyte Additive, 10-50 g\/bottle, CBEAES","description":"\u003cp\u003eEthylene Sulfite (ES)—systematically named 1,3,2-dioxathiolane 2-oxide—is a cyclic sulfur-containing organic ester widely used as a film-forming SEI\/CEI additive and PC-co-solvent suppressor in non-aqueous electrolytes for lithium-ion, lithium-metal, and sodium-ion batteries. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSacrificial Reduction \u0026amp; Sulfur-Rich Inorganic SEI\u003c\/strong\u003e: Ethylene Sulfite possesses a higher reduction potential (~ 1.2 V to1.4 V vs. Li\/Li+) than cyclic carbonates like ethylene carbonate (EC) or propylene carbonate (PC). During initial formation, ES preferentially reduces at the anode surface, cleavage of the C–O and S–O bonds yields an inorganic-rich Solid Electrolyte Interphase (SEI) dominated by inorganic sulfur species (such as lithium sulfite, Li2SO3, and lithium sulfide, Li2S) alongside alkyl sulfites (CH2OSO2Li2).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInhibition of Graphite Exfoliation in PC-Rich Formulations\u003c\/strong\u003e: Standard Propylene Carbonate (PC) causes destructive graphite exfoliation due to co-intercalation of solvated Li+ or Na+ ions. Adding a small quantity of ES forms a dense, passivating SEI on graphite prior to PC reduction, suppressing co-intercalation and enabling PC-based electrolytes to cycle stably on graphite anodes at sub-zero temperatures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCathode Interphase Passivation (CEI)\u003c\/strong\u003e: ES also participates in oxidative passivation at cathode surfaces above 4.2 V vs. Li\/Li+. The resulting Cathode Electrolyte Interphase (CEI) mitigates transition-metal leaching Ni^(3+)\/Ni^(4+), Mn^(3+) and reduces oxygen release from high-nickel layered oxides or high-manganese cathodes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLower Interfacial Charge-Transfer Impedance\u003c\/strong\u003e: The inorganic sulfur species (Li2SO3 \/ Li2S) formed within the SEI exhibit significantly higher ionic conductivity for Li+ or Na+ cations compared to standard organic alkyl carbonate reduction products (ROCO2Li). This reduces charge-transfer resistance and improves low-temperature rate performance.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 318.8px;\"\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\u003eCBEAES (C-BEA-ES)\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\u003e3741-38-6\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 98px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 98px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 98px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eS\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEAES_02_100x100.jpg?v=1785984007\" 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\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; 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: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e108.12 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\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e1.433 g\/mL at 25 °C\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\u003eBoiling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e159.1 °C (lit.)\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\u003e10 g, 20 g, and 50 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 EC solution 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:\/\/pubs.rsc.org\/ee\/article-abstract\/2\/10\/1102\/106617\/Vinyl-ethylene-sulfite-as-a-new-additive-in\"\u003e\u003cspan\u003eW.
