{"product_id":"cbeabmc","title":"BMC {Bis(2-methoxyethyl) Carbonate, BMEC, 99.0%} as Battery Electrolyte Additive, 5-25 g\/bottle, CBEABMC","description":"\u003cp\u003eBis(2-methoxyethyl) carbonate (commonly designated as BMC, BMEC, or diethyl ether-functionalized organic carbonate) is an advanced symmetric carbonate ester engineered as a high-performance electrolyte solvent, co-solvent, and functional additive for next-generation lithium-ion and sodium-ion batteries. By integrating polar methoxyethyl functional groups into the linear carbonate backbone, BMC provides a unique combination of high boiling points, enhanced safety profiles, and modified solvation behavior compared to conventional short-chain alkyl carbonates.\u003c\/p\u003e\n\u003cp\u003eIts functional roles in electrolyte engineering are: (1) \u003cstrong\u003eSolvation Sheath \u0026amp; Anion Coordination Tuning\u003c\/strong\u003e: BMC modifies the primary alkali metal ion coordination shell, balancing salt dissociation against restrained electron-donating reactivity. This helps encourage stable ion transport dynamics across varying temperature regimes. (2) \u003cstrong\u003eInterphase (SEI\/CEI) Passivation\u003c\/strong\u003e: Due to its specific reduction and oxidation potentials, BMC participates in early-stage electrochemical formation, contributing to the construction of a robust, protective Solid Electrolyte Interphase (SEI) on anodes and a stabilizing Cathode Electrolyte Interphase (CEI) on positive electrodes. (3) \u003cstrong\u003eThermal Safety \u0026amp; Volatility Suppression\u003c\/strong\u003e: With a remarkably high boiling point (~232 °C) and a safe flash point (~86 °C) compared to traditional low-boiling linear carbonates (like DMC or EMC), BMC heavily suppresses bulk electrolyte volatility and reduces fire hazards during thermal abuse or high-temperature storage.\u003c\/p\u003e\n\u003cp\u003eIts primary electrochemical application domains are: (1) \u003cstrong\u003eHigh-Voltage Lithium-Ion Full Cells\u003c\/strong\u003e: Integrated into master carbonate electrolytes (such as LiPF6 blends) to improve thermal stability, reduce gassing, and support cells operating at elevated voltage thresholds. (2) \u003cstrong\u003eAdvanced Sodium-Ion Systems\u003c\/strong\u003e: Utilized as a specialized co-solvent or additive to tailor the interfacial chemistry and solvation structure for sodium metal or hard carbon anodes.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 296.6px;\" 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\u003eCBEABMC (C-BEA-BMC)\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\u003cimg\u003e626-84-6\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 116px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 116px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 116px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e7\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e1\u003c\/sub\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e5\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\/CBEABMC_Structure_100x100.jpg?v=1789970025\" 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: 18.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 18.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 18.6px;\"\u003e\u003cspan\u003e178.18 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\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 \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the BMC (or BMEC) liquid in a dry place (glovebox is the best option).\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\/s41467-024-47448-5\"\u003e\u003cspan\u003eJ.
