{"product_id":"cbeatcep","title":"TCEP {1,2,3-Tris(2-cyanoethoxy)propane, TPPN, \u003e99.0%} as Battery Electrolyte Additive, 10-50 g\/bottle, CBEATCEP","description":"\u003cp\u003e1,2,3-Tris(2-cyanoethoxy)propane (commonly designated as TCEP or TPPN) is a specialized multi-nitrile ether compound engineered as a high-performance electrolyte additive and interphase-stabilizing agent for advanced lithium-ion and high-voltage lithium-metal batteries. By featuring three polar cyanoethoxy branches attached to a central propane backbone, TCEP delivers exceptional coordination capability and interfacial passivation under high-voltage operating conditions.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles of the TCEP are: (1) \u003cstrong\u003eRobust Cathode-Electrolyte Interphase (CEI) Formation\u003c\/strong\u003e: Due to the oxidation activity of the electron-withdrawing nitrile groups, TCEP preferentially participates in sacrificial electrochemical oxidation at the surface of high-voltage cathodes during initial charging. This builds a uniform, protective CEI layer that suppresses continuous solvent breakdown and gas evolution. (2) \u003cstrong\u003eMitigation of Transition-Metal Dissolution\u003c\/strong\u003e: The nitrogen-rich molecular fragments coordinate strongly with exposed transition metal ions on high-nickel cathode surfaces, effectively passivating catalytic sites and preventing structural degradation (such as phase transitions from layered to rock-salt structures). (3) \u003cstrong\u003eAnode Passivation Support (SEI Enhancement)\u003c\/strong\u003e: Reduction products derived from the cyanoalkyl groups assist in forming a stable, nitrogen-containing inorganic-organic hybrid Solid Electrolyte Interphase (SEI) on graphite or silicon composite anodes, curbing ongoing electrolyte consumption. (4) \u003cstrong\u003eSolvation Sheath \u0026amp; Viscosity Modification\u003c\/strong\u003e: While maintaining moderate fluidity, TCEP gently modulates the local lithium-ion coordination shell, encouraging beneficial anion participation in the inner solvation sphere.\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 extended cycle stability and capacity retention in cells operating at upper cut-off voltages exceeding 4.3 V to 4.5 V. (2) \u003cstrong\u003eHigh-Nickel and Cobalt-Rich Chemistries\u003c\/strong\u003e: Deployed alongside nickel-rich layered oxide cathodes (such as NMC811) to mitigate high-temperature impedance growth and minimize capacity fade under aggressive cycling protocols.\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\u003eCBEATCEP (C-BEA-TCEP)\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\u003e2465-93-2\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\u003e1\u003c\/sub\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e1\u003c\/sub\u003e\u003csub\u003e7\u003c\/sub\u003e\u003cspan\u003eN\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eO\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\/CBEATCEP_Structure_100x100.jpg?v=1789956356\" 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\u003e251.29 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\u003e10 g, 25 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\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please store the TCEP 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:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.78116\"\u003eJ.
