{"product_id":"chplibselfpg","title":"Specific Electrolyte for High-Performance Lithium-Ion Battery {LiFePO4 + Graphite}, 200 g\/bottle, CHPLIBSELFPG","description":"\u003cp\u003eOperating a lithium-ion cell with a Lithium Iron Phosphate ({LiFePO4 \/ LFP) positive electrode paired with a Graphite (Gr) negative electrode presents a distinct electrochemical environment compared to high-voltage cobalt or nickel chemistries. LFP operates at a flat, moderate potential plateau (~ 3.4 V vs. Li\/Li+) and possesses an exceptionally stable olivine crystal structure that does not suffer from lattice oxygen release or severe transition metal dissolution. Consequently, the primary electrolyte engineering goals for LFP \/\/ Graphite cells shift away from high-voltage oxidative shielding toward low interfacial resistance, wide temperature operational stability, minimal iron dissolution, and long calendar\/cycle life.\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). LiPF6 provides an optimal balance of ionic conductivity, thermal dissociation, and critical passivation of aluminum current collectors at moderate potentials (~3.5 V). Dual-salt variations (adding 0.2–0.5 M LiFSI) are sometimes utilized for ultra-low temperature or high-rate capability, but standard LiPF6 remains the commercial baseline for cost-effective longevity. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: Ethylene Carbonate (EC) blended with linear carbonates such as Ethyl Methyl Carbonate (EMC) or Dimethyl Carbonate (DMC). A standard baseline ratio is EC:EMC = 3:7 or 3:8 (by weight). (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) 1.0 wt% to 2.0 wt% Vinylene Carbonate (VC): The gold-standard passivating additive for LFP \/\/ Graphite systems. VC undergoes preferential two-electron reduction on the graphite anode during initial formation, building a stable, low-impedance polymeric\/inorganic SEI that suppresses continuous electrolyte consumption and prevents gas generation. (ii) 0.5 wt% to 1.0 wt% Fluoroethylene Carbonate (FEC): Often co-added in minor amounts (especially for wide-temperature formulations) to further enhance low-temperature charge acceptance and stabilize the graphite interphase. (iii) 0.5 wt% Lithium difluoro(oxalato)borate (LiDFOB) or LiBOB (Optional): Assists in mitigating trace iron dissolution from the LFP cathode over extended high-temperature storage (calendar aging).\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\u003eCHPLIBSELFPG (C-HPLIB-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 + Graphtie\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:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/anie.202409409\"\u003e\u003cspan\u003eZ.
