{"product_id":"clibealitfop","title":"LiTFOP (Lithium tetrafluoro(oxalato)phosphate, \u003e99.5%) Powder as Electrolyte Additive for Lithium-Ion Battery, 10-50 g\/bottle, CLIBEALiTFOP","description":"\u003cp\u003eLithium Tetrafluoro(oxalato)phosphate—abbreviated as LiTFOP, LiOTFP, or LiPF4(C2O4)—is a chelated organophosphorus lithium-salt additive. Combining a central phosphorus atom bound to four fluorine atoms and one bidentate oxalate ligand, it acts as a film-forming interphase builder and thermal stabilizer for high-voltage, fast-charging lithium-ion and lithium-metal batteries. The core functional roles \u0026amp; electrochemical advantages are shown below:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual-Sided Interphase Passivation (SEI \u0026amp; CEI)\u003c\/strong\u003e: (1) \u003cem\u003eAnode (SEI)\u003c\/em\u003e: Owing to its lower LUMO energy level relative to baseline carbonate solvents, LiTFOP undergoes sacrificial reduction at ~ 1.3–1.5 V vs. Li\/Li+. Ring-opening of the oxalate ligand polymerizes into an organic matrix, while fluorine and phosphorus moieties yield a hybrid inorganic\/organic Solid Electrolyte Interphase (SEI) rich in LiF and lithium phosphates LixPOyFz). (2) \u003cem\u003eCathode (CEI)\u003c\/em\u003e: Under oxidation at high potentials (\u0026gt;4.3–4.5 V vs. Li\/Li+), the oxalate unit forms a dense Cathode Electrolyte Interphase (CEI) on nickel-rich (NMC811, NCMA) and high-voltage cobalt oxides. This layer passivates active surface oxygen sites and suppresses transition-metal leaching.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow Charge-Transfer Impedance \u0026amp; Rapid Kinetics\u003c\/strong\u003e: The LiF- and Li3PO4-rich inorganic species generated by LiTFOP offer lower activation energy barriers for Li+ desolvation. This significantly reduces interfacial charge-transfer resistance (Rct) at both electrode interfaces compared to mono-salt additives, aiding rate capability and fast-charging performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEnhanced Thermal Stability vs. Standard LiPF6\u003c\/strong\u003e: Unlike LiPF6, which undergoes thermal decomposition into volatile PF5 gas at elevated temperatures, the oxalate-chelated phosphorus structure in LiTFOP exhibits higher thermal decomposition thresholds. When added to carbonate electrolytes, it mitigates autocatalytic electrolyte breakdown and suppresses cell swelling during high-temperature aging. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDendrite Inhibition on Lithium Metal\u003c\/strong\u003e: The uniform LiF-dense inner SEI layer levels local electric field variations on alkali-metal anodes, promoting homogeneous Li+ flux and suppressing dendritic growth in lithium-metal systems.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 241px;\"\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\u003eCLIBEALiTFOP (C-LIB-EA-LiTFOP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 95px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 95px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 95px;\"\u003e\n\u003cp\u003eC2F4LiO4P\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBEALiTFOP_02_100x100.jpg?v=1786242737\" 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 Powder\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;99.5% (Battery Grade)\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\u003e201.93 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;\"\u003e10 g, 25 g, and 50 g\/bottle\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 LiTFOP powder in the glovebox due to its sensitivity to humidity and oxygen\u003c\/span\u003e\u003cspan\u003e \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:\/\/iopscience.iop.org\/article\/10.1149\/1.3261738\/meta\"\u003e\u003cspan\u003eY.
