{"product_id":"cbeaimpc","title":"IMPC (Propargyl 1H-imidazole-1-carboxylate, \u003e98.0%) as Battery Electrolyte Additive, 5-25 g\/bottle, CBEAIMPC","description":"\u003cp\u003eIMPC, Propargyl 1H-imidazole-1-carboxylate (also known as PImC, prop-2-yn-1-yl 1H-imidazole-1-carboxylate, or the Heller-Sarpong Reagent) is a multifunctional organic compound used primarily as a film-forming functional additive in non-aqueous electrolytes for high-voltage lithium-ion, lithium-metal, and post-lithium battery systems. Combining an unsaturated alkyne group, a carbonate linkage (-O-COO-), and an imidazole ring, this molecule functions as a dual-working interphase builder and acid scavenger.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual-Layer Interphase Passivation (SEI \u0026amp; CEI)\u003c\/strong\u003e: (1) \u003cem\u003eAnode (SEI)\u003c\/em\u003e: The reactive terminal alkyne group (-HC≡C-) undergoes sacrificial reduction at potentials higher than baseline carbonate solvents (typically around 1.2 V to 1.5 V vs. Li\/Li+). Polymerization of the triple bond generates an organic-rich, elastic poly-alkyne\/carbonate network on graphite or lithium metal anodes. (2) \u003cem\u003eCathode (CEI)\u003c\/em\u003e: The imidazole ring and carbonate core oxidatively polymerize at cathode surfaces at elevated cutoff voltages (\u0026gt; 4.4 V vs. Li\/Li+), creating a thin, protective Cathode Electrolyte Interphase (CEI) that mitigates transition-metal leaching (e.g., Ni^{3+}\/Ni^{4+}, Mn^{3+}) in nickel-rich NMC or high-voltage LCO chemistries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransition Metal Coordination \u0026amp; Dissolution Suppression\u003c\/strong\u003e: Nitrogen atoms on the imidazole ring act as Lewis bases, coordinating with active transition-metal sites at the cathode surface. This passivates catalytic surface defect sites, blocking parasitic side reactions and suppressing transition-metal migration to the anode.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHF and Lewis Acid Scavenging\u003c\/strong\u003e: In standard LiPF6-based electrolytes, hydrolysis by trace water yields hydrofluoric acid (HF) and Lewis-acidic PF5. The basic nitrogen site on the imidazole moiety scavenges PF5 and neutralizes HF, halting autocatalytic electrolyte degradation, reducing impedance growth, and suppressing gas generation during high-temperature aging (55°C-60°C).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuppression of Lithium Dendrite Growth\u003c\/strong\u003e: The uniform cross-linked interphase derived from propargyl polymerization levels the local electric field across alkali-metal anodes, fostering uniform Li+ (or Na+) ion flux and inhibiting dendritic growth in lithium-metal cells.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 301.325px;\"\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\u003eCBEAIMPC (C-BEA-IMPC)\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\u003e83395-38-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 125.725px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 125.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 125.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e7\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eN\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eO\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\/CBEAIMPC_02_100x100.jpg?v=1785956084\" 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 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;98.0%\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\u003e150.13 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\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e~45-50 °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\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 store the IMPC powder in a dry place.\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:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsami.4c02237\"\u003eZ.
