{"product_id":"cfclibselfpg","title":"Specific Electrolyte for Fast-Charging Lithium-Ion Battery {LiFePO4 + Graphite}, 200 g\/bottle, CFCLIBSELFPG","description":"\u003cp\u003eDesigning an electrolyte optimized for ultra-fast-charging (UFC) Lithium Iron Phosphate (LiFePO4 \/ LFP) \/\/ Graphite cells requires minimizing interfacial resistance, accelerating desolvation kinetics at the electrode surfaces, and preventing destructive lithium plating (dendrite formation) under high-rate current loads (e.g., 4C to 10C charging). Unlike standard cycling formulations, fast-charging electrolytes prioritize low bulk viscosity, high ionic conductivity, and specialized solvation sheath engineering to facilitate rapid Li+ transport through both the separator and the porous electrode tortuosity.\u003c\/p\u003e\n\u003cp\u003eThe recommended fast-charging electrolyte formulation (UFC LFP \/\/ Graphite) are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.0 M LiPF6 + 0.5 M Lithium bis(fluorosulfonyl)imide (LiFSI). Integrating LiFSI alongside LiPF6 significantly enhances ionic conductivity and lowers the desolvation activation energy of Li+ ions. Furthermore, LiFSI promotes the rapid formation of a thin, highly conductive, inorganic-rich (LiF) Solid Electrolyte Interphase (SEI) on the graphite anode, minimizing charge-transfer resistance (R_ct) during high-rate pulses. (2) \u003cstrong\u003eLow-Viscosity Solvent Architecture\u003c\/strong\u003e: Low-viscosity linear carbonates paired with minimal cyclic fractions. A typical optimized ratio is Propylene Carbonate (PC) \/ Dimethyl Carbonate (DMC) \/ Ethyl Methyl Carbonate (EMC) (e.g., a lean EC system or low-viscosity blend such as EC:EMC:DMC = 1:1:8 by weight). High proportions of low-viscosity linear carbonates (like DMC) drastically accelerate bulk transport rates and maintain high ionic conductivity (~ 12-15 mS\/cm at room temperature), preventing concentration polarization at the electrode faces during high-current charging. (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) 1.0 wt% to 2.0 wt% Fluoroethylene Carbonate (FEC): Vital for stabilizing the graphite anode against exfoliation and solvent co-intercalation, especially under high-rate potentials where polarization can approach the lithium plating threshold. (ii) 0.5 wt% to 1.0 wt% Lithium difluoro(oxalato)borate (LiDFOB): Works synergistically with LiFSI to form a robust, low-impedance passivating film that supports rapid charge-transfer kinetics without triggering excessive interfacial polarization. (iii) 0.5 wt% Succinonitrile (SN) or Adiponitrile (ADN): Nitrile-based additives coordinate weakly with Li+ and optimize the interfacial solvation structure, effectively homogenizing current distribution and suppressing localized lithium plating on graphite during fast charging.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 288.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCFCLIBSELFPG (C-FCLIB-SE-LFPG)\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: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; 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: 55.2px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 55.2px;\"\u003e\u003cem\u003eElectrolyte Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 55.2px;\"\u003e\n\u003cp\u003eUndisclosed recipe from leading manufacturer that has been well demonstrated in pilot-scale LIB. \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eHumidity Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;20 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 35.6px;\"\u003e\u003cem\u003eAcid Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;100 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 71.2px;\"\u003e\u003cem\u003ePerformance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 71.2px;\"\u003e\n\u003cp\u003e~ 3.2-3.4 V vs. Li\/Li+, LiFePO4 + Graphite\u003c\/p\u003e\n\u003cp\u003e5C-10C\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 19.6px;\"\u003e\u003cspan\u003e200 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 specific LIB electrolyte in the glovebox due to its sensitivity to humidity.\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:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/anie.202521171\"\u003eZ.
