{"product_id":"cbeabdtd","title":"BDTD {[4, 4′-bi(1,3,2-dioxathiolane)] 2,2′-dioxide, \u003e99.0%} as Battery Electrolyte Additive, 5-25 g\/bottle, CBEABDTD","description":"\u003cp\u003eBDTD ([4,4'-bi(1,3,2-dioxathiolane)] 2,2'-dioxide or more precisely 4,4'-bi(1,3,2-dioxathiolane) 2,2,2',2'-tetraoxide) is an advanced, multi-functional dimeric cyclic sulfate compound engineered as a high-performance electrolyte additive for advanced lithium-ion and high-voltage lithium-metal batteries. By linking two cyclic sulfate rings into a rigid dimeric architecture, BDTD provides exceptional interfacial stabilization and radical scavenging capabilities under high-voltage and high-temperature stress.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of the BDTD are: (1) \u003cstrong\u003eSacrificial Cathode-Electrolyte Interphase (CEI) Formation\u003c\/strong\u003e: BDTD preferentially oxidizes at the surface of high-voltage transition metal oxide cathodes during early-stage charging. This sacrificial oxidation yields a uniform, passivating CEI layer that suppresses continuous electrolyte oxidation, transition-metal dissolution, and parasitic gas generation. (2) \u003cstrong\u003eRobust Anode Passivation (SEI Enhancement)\u003c\/strong\u003e: Beyond its primary role at the positive electrode, reduction products derived from the multi-functional cyclic sulfate moieties participate in forming an inorganic-rich, highly stable Solid Electrolyte Interphase (SEI) on graphite, silicon-composite, or lithium metal anodes. (3) \u003cstrong\u003eImpedance Mitigation \u0026amp; Structural Protection\u003c\/strong\u003e: By establishing a thin, electronically insulating yet ionically conductive dual-interphase film, BDTD prevents the progressive impedance growth typically associated with repeated solvent breakdown and surface phase transitions on high-nickel cathodes. (4) \u003cstrong\u003eThermal and Overcharge Stability\u003c\/strong\u003e: The rigid dimeric sulfate structure enhances thermal resistance, helping mitigate exothermic runaway reactions during abusive thermal or overcharge testing.\u003c\/p\u003e\n\u003cp\u003eIts primary electrochemical domains are: (1) \u003cstrong\u003eHigh-Voltage Lithium-Ion Full Cells\u003c\/strong\u003e: Integrated into standard carbonate master electrolytes (e.g., LiPF6 in EC\/EMC) to support cells cycled at upper cut-off voltages exceeding 4.5 V to 4.6 V (such as with high-nickel NMC811 or high-voltage cobalt systems). (2) \u003cstrong\u003eSilicon-Anode and High-Energy Integrations\u003c\/strong\u003e: Deployed to stabilize the highly reactive surfaces of silicon-containing anodes, accommodating volumetric shifts while curbing continuous electrolyte consumption.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 244.325px;\"\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\u003eCBEABDTD (C-BEA-BDTD)\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\u003e1914148-67-6\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 62.725px;\"\u003e\n\u003ctd style=\"width: 33.8802%; height: 62.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7989%; height: 62.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eS\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\/CBEABDTD_Structure_100x100.jpg?v=1789953747\" 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\u003e214.22 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 BDTD 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\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775317316282\"\u003eS.
