{"product_id":"clibsehncmsic","title":"Specific Electrolyte for Lithium-Ion Battery {NCM (Ni≥80%) + Si\/C}, 200 g\/bottle, CLIBSEHNCMSiC","description":"\u003cp\u003eOperating a high-energy-density lithium-ion cell with an ultra-high nickel cathode (NCM ≥ 80%, such as NCM811 NCM9055) paired with a Silicon-Carbon (Si\/C) composite anode represents the pinnacle of modern commercial energy density, but it also creates the most aggressive interfacial environment in battery electrochemistry. At the cathode interface, highly reactive Ni^{4+} species, lattice oxygen release, and high operational voltages (\u0026gt;4.3 V) drive severe oxidative decomposition and transition-metal dissolution. Simultaneously, at the anode interface, the silicon component undergoes extreme volumetric fluctuations (~ 200-300%), which shatters conventional solid electrolyte interphases (SEI) and triggers continuous, parasitic electrolyte consumption paired with severe gassing.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003e1.1 to 1.2 M LiPF6 + 0.4 to 0.6 Lithium bis(fluorosulfonyl)imide (LiFSI). \u003cspan class=\"math-inline\" data-math=\"\\text{LiPF}_6\" data-index-in-node=\"14\"\u003eLiPF6\u003c\/span\u003e is strictly required to passivate the aluminum current collector against pitting corrosion at high potentials. The high concentration of \u003cspan class=\"math-inline\" data-math=\"\\text{LiFSI}\" data-index-in-node=\"165\"\u003eLiFSI\u003c\/span\u003e suppresses free solvent activity, lowers desolvation activation energy, and provides an abundant flux of fluoride ions to construct a dense, inorganic-rich (\u003cspan class=\"math-inline\" data-math=\"\\text{LiF}\" data-index-in-node=\"335\"\u003eLiF\u003c\/span\u003e) passivating network on both the expanding silicon surfaces and the high-voltage cathode. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: (i) \u003cem\u003eCore Solvents\u003c\/em\u003e: Ethylene Carbonate (EC) + Ethyl Methyl Carbonate (EMC) + Dimethyl Carbonate (DMC) restricted to a lean-EC framework (e.g., EC:EMC:DMC = 2:5:3 or 1:6:3 by weight). (ii) \u003cem\u003eFluorinated Co-Solvent \/ Diluent Option\u003c\/em\u003e: Incorporation of a high-performance fluorinated component (such as ETFEC, MHFPC, or a fluorinated ether like TTE or TFEE) to form a localized high-concentration or fluorinated-hybrid system. This raises the oxidative stability threshold well above 4.4 V and substantially improves thermal safety under abuse conditions. (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) \u003cem\u003e4.0 wt% to 7.0 wt% Fluoroethylene Carbonate (FEC)\u003c\/em\u003e: Indispensable for silicon-containing anodes. High-content FEC ensures the formation of a highly elastic, self-healing, LiF-rich SEI capable of flexing with the severe breathing of the Si\/C particles without cracking. (ii) \u003cem\u003e1.0 wt% to 1.5 wt% Lithium difluoro(oxalato)borate (LiDFOB) or LiBOB\u003c\/em\u003e: Forms a robust, protective boron- and oxalate-rich Cathode Electrolyte Interphase (CEI) directly on the vulnerable NCM811 surface, shielding the lattice from oxygen loss and stabilizing surface phase transitions. (iii) 1.0 wt% Tris(trimethylsilyl) phosphite (TMSPi) or Phenyl 4-fluorobenzene sulfonate (PFBS): Acts as a powerful hydrofluoric acid (HF) scavenger and protective film-former, neutralizing trace acid to prevent the acid-catalyzed disproportionation and dissolution of surface nickel ions.\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\u003eCLIBSEHNCMSiC (C-LIB-SE-HNCMSiC)\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\u0026gt;4.4 V, NCM (Ni≥80%, eg: NCM811, NCM9055) + Si\/C\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.sciencedirect.com\/science\/article\/abs\/pii\/S2405829725005070\"\u003eJ.
