{"product_id":"clclibselfpg","title":"Specific Electrolyte for Long-Cycling Lithium-Ion Battery {LiFePO4 + Graphite}, 200 g\/bottle, CLCLIBSELFPG","description":"\u003cp\u003eDesigning an electrolyte optimized for long-cycling, calendar-stable Lithium Iron Phosphate (LiFePO4 \/ LFP) \/\/ Graphite cells requires focusing on long-term interfacial stability, suppressing transition metal (iron) dissolution and migration, maintaining a stable and elastic Solid Electrolyte Interphase (SEI) on the graphite anode, and preventing electrolyte dry-up over thousands of deep cycles. While LFP is inherently stable due to its robust olivine framework, achieving ultra-long cycle life (e.g., 3,000-6,000+ cycles) demands careful management of parasitic side reactions and parasitic hydrogen\/gas evolution at the anode.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.0 M to 1.2 M Lithium hexafluorophosphate (LiPF6) with ultra-low free acid (HF \u0026lt; 20 ppm) and moisture (H2O \u0026lt; 10 ppm). LiPF6 provides the necessary passivation film on aluminum current collectors at moderate potentials (~3.5 V). Ultra-high purity is non-negotiable for long cycling; minimizing trace acid prevents slow, cumulative iron dissolution from the LFP cathode and subsequent deposition on the graphite anode (which acts as a catalyst for continuous electrolyte decomposition). (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: Ethylene Carbonate (EC) + Ethyl Methyl Carbonate (EMC) + Dimethyl Carbonate (DMC). A balanced volumetric or weight ratio, such as EC:EMC:DMC = 1:1:1 or 2:4:4, provides an optimal trade-off between wetting capability, viscosity, and film-forming ability. Maintaining an adequate EC fraction (typically 20–30 wt.%) ensures a continuous supply of precursor for a stable, regenerating graphite SEI, while the linear carbonate blend prevents excessive viscosity increases over long-term aging. (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) 1.5 wt% to 2.0 wt% Vinylene Carbonate (VC): The foundational additive for long-term SEI stabilization on graphite. VC polymerizes during initial formation to construct a dense, low-impedance interfacial layer that suppresses ongoing solvent reduction and gas generation. (ii) 0.5 wt% to 1.0 wt% Lithium difluoro(oxalato)borate (LiDFOB) or LiBOB: Acts as a dual-functional stabilizer. It assists in reinforcing the anode SEI while forming a protective, boron-based passivating layer on the LFP cathode surface to inhibit iron dissolution and surface reconstruction. (iii) 0.5 wt% 1,3,6-Hexanetricarbonitrile (HTCN) or Succinonitrile (SN): Nitrile co-additives coordinate with transition metal ions and trace impurities, effectively scavenging reactive species and preventing them from migrating across the separator to poison the anode interphase.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 118.6px;\" 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\u003eCLCLIBSELFPG (C-LCLIB-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: 27.8px;\"\u003e\n\u003ctd style=\"width: 36.7332%; height: 27.8px;\"\u003e\u003cem\u003eElectrolyte Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%; height: 27.8px;\"\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\u003e\n\u003ctd style=\"width: 36.7332%;\"\u003e\u003cem\u003eHumidity Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%;\"\u003e\n\u003cp\u003e\u0026lt;20 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 36.7332%;\"\u003e\u003cem\u003eAcid Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%;\"\u003e\n\u003cp\u003e\u0026lt;100 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 36.7332%;\"\u003e\u003cem\u003ePerformance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9458%;\"\u003e\n\u003cp\u003e~ 3.2-3.4 V vs. Li\/Li+, LiFePO4 + Graphite\u003c\/p\u003e\n\u003cp\u003e\u0026gt;1000 cycles\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\u003ca href=\"https:\/\/iopscience.iop.org\/article\/10.1149\/1945-7111\/ac67f9\/meta\"\u003e\u003cspan\u003eE.
