{"product_id":"cbeatpp","title":"TPP (Tripropargyl Phosphate, \u003e99.0%) as Battery Electrolyte Additive, 5 g\/bottle, CBEATPP","description":"\u003cp\u003eTripropargyl Phosphate (TPP)—systematically named tri(prop-2-yn-1-yl) phosphate—is a multifunctional phosphate ester additive combining three reactive alkyne (propargyl) groups with a central phosphate core (O=P(O-CH2-C\u003cspan\u003e≡\u003c\/span\u003eCH3). It is widely used as a high-performance, film-forming additive, flame retardant, and structural stabilizer in non-aqueous electrolytes for high-voltage lithium-ion (LIBs), lithium-metal, and post-lithium battery systems. The core functional roles \u0026amp; electrochemical advantages are shown below:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRobust Cathode Electrolyte Interphase (CEI) Formation\u003c\/strong\u003e: High-voltage operation (\u0026gt;4.4 V vs. Li\/Li+) accelerates conventional carbonate solvent oxidation at cathode surfaces. Due to its lower Highest Occupied Molecular Orbital (HOMO) energy level compared to standard carbonates, TPP oxidizes preferentially on nickel-rich cathodes (e.g., NMC811, NCMA) and high-voltage cobalt-free\/spinel cathodes. Ring-opening and radical polymerization of the three carbon-carbon triple bonds (C\u003cspan\u003e≡\u003c\/span\u003eC) yield a dense, highly cross-linked, phosphorus- and organic-rich CEI layer. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransition Metal Coordination \u0026amp; Dissolution Suppression\u003c\/strong\u003e: The electron-rich phosphate carbonyl oxygen (P=O) and alkyne moieties coordinate with catalytic transition-metal sites (Ni^{3+}\/Ni^{4+}, Mn^{3+}) on cathode surfaces. This passivates active surface defect sites, suppressing transition-metal leaching, structural phase transitions (e.g., layered-to-rocksalt phase transformation), and subsequent metal ion migration to the anode.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInelastic Poly-Alkyne SEI on Anodes\u003c\/strong\u003e: TPP also participates in sacrificial reduction on graphite or lithium-metal anodes at potentials around 1.3 V to 1.5 V vs. Li\/Li+. The three propargyl arms polymerize into a flexible, conductive organic-inorganic interphase that promotes uniform Li+ ion flux and inhibits dendritic lithium growth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlame Retardancy \u0026amp; Thermal Stability Enhancement\u003c\/strong\u003e: Like other organic phosphate esters, the phosphate group (PO4)^{3-}-like core) acts as a radical scavenger in the gas phase during thermal abuse events. It suppresses electrolyte flammability and reduces self-extinguishing time (SET), improving overall battery safety under elevated temperatures (55-60°C).\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 321.6px;\" 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\u003eCBEATPP (C-BEA-TPP)\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\u003e1779-34-6\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 140px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 140px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 140px;\"\u003e\n\u003cp\u003eC9H9O4P\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEATPP_02_100x100.jpg?v=1786129746\" 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% (moisture sensitive)\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\u003e212.14 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\/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 TPP liquid in a 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:\/\/pubs.acs.org\/aamick\/article-abstract\/12\/9\/10443\/448540\/Mechanism-Study-of-Unsaturated-Tripropargyl?redirectedFrom=fulltext\"\u003eY.
