{"product_id":"chvlibselcosic","title":"Specific Electrolyte for High-Voltage Lithium-Ion Battery {≥4.4V LiCoO2 + Si\/C, Si≤20%}, 200 g\/bottle, CHVLIBSELCOSiC","description":"\u003cp\u003ePairing a high-voltage Lithium Cobalt Oxide (LiCoO2 \/ LCO) cathode charged to ~ 4.4 V–4.5 V with a Silicon-Carbon (Si\/C, 20 wt% silicon content) composite anode creates severe dual-interface challenges. The high-potential LCO requires an electrolyte with strong oxidation resistance to suppress cobalt dissolution and lattice oxygen release, while the silicon component demands a robust, elastic passivating layer to accommodate large volume fluctuations (~ 250-300%) and prevent continuous electrolyte consumption.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.2 M dual-salt composition consisting of 1.0 M LiPF6 + 0.2 M Lithium bis(fluorosulfonyl)imide (LiFSI). LiPF6 ensures effective passivation of aluminum current collectors at high potentials, while the minor LiFSI component facilitates the rapid generation of an inorganic-rich, flexible fluoride layer essential for stabilizing the volume-changing silicon surface. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: (i) \u003cem\u003eCore Solvents\u003c\/em\u003e: Ethylene Carbonate (EC) + Diethyl Carbonate (DEC) + Fluoroethylene Carbonate (FEC) balanced to minimize gas evolution while maintaining high ionic conductivity. A typical optimized ratio is EC:DEC = 3:7 by weight supplemented by high-concentration functional co-solvents. (ii) \u003cem\u003eLocalized High-Concentration (LHCE) Alternative\u003c\/em\u003e: For ultra-stable high-voltage cycling, a localized high-concentration matrix utilizing a fluorinated ether diluent (such as TTE or TFEE) helps lock down solvent reactivity against both the 4.4 V+ LCO surface and the lithiated silicon matrix. (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) 5.0 wt% Fluoroethylene Carbonate (FEC): Non-negotiable for silicon-composite anodes; acts as the primary reductive precursor to build a dense, elastic, LiF-rich Solid Electrolyte Interphase (SEI) that accommodates particle breathing. (ii) 1.5 wt% Lithium difluoro(oxalato)borate (LiDFOB) or LiBOB: Forms a protective boron- and oxalate-based passivating film on the high-voltage LCO surface (forming a stable Cathode Electrolyte Interphase \/ CEI) to mitigate transition metal leaching. (iii) 1.0 wt% Vinylene Carbonate (VC) or Succinonitrile (SN): Works synergistically with FEC to optimize interfacial resistance and reduce gas generation during initial formation cycles.\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\u003eCHVLIBSELCOSiC (C-HVLIB-SE-LCOSiC)\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≥4.4V, LiCoO2 + Si\/C, ~450-500 mAh\/g (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003efor reference only\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: 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:\/\/www.cell.com\/joule\/abstract\/S2542-4351(25)00347-2\"\u003eZ.
