At these elevated cutoff voltages, standard carbonate electrolytes undergo accelerated oxidative decomposition, leading to transition-metal dissolution (Ni^{2+}, Co^{2+}, Mn^{2+}), reactive oxygen release from the lattice, and continuous structural micro-cracking at the secondary particle boundaries.\u003c\/p\u003e\n\u003cp\u003eThe recommended electrolyte recipe are shown below: (1) \u003cstrong\u003eSalt Framework: \u003c\/strong\u003eThe primary salt is\u003cstrong\u003e \u003c\/strong\u003e1.0 M to 1.2 M LiPF6 (essential for passivating the aluminum current collector against pitting corrosion at potentials \u0026gt;4.3 V). The secondary salt additive can be 0.1 M to 0.2 M Lithium bis(fluorosulfonyl)imide (LiFSI) to enhance ionic conductivity and assist in forming a robust, inorganic-rich Solid Electrolyte Interphase (SEI) on the graphite anode. (2) \u003cstrong\u003eSolvent Architecture\u003c\/strong\u003e: (i) \u003cem\u003eCore Solvents\u003c\/em\u003e: Ethylene Carbonate (EC) + Ethyl Methyl Carbonate (EMC) + Dimethyl Carbonate (DMC). A balanced weight ratio like EC:EMC:DMC = 2:4:4 or a restricted-EC formulation (EC:EMC = 3:7) minimizes excessive solvent oxidation while maintaining excellent separator wetting and low bulk viscosity. Incorporation of a minor fraction (e.g., 5–15 wt.%) of a fluorinated ether (such as TTE or TFEE) or a fluorinated carbonate (like ETFEC or MHFPC) to suppress free solvent activity and widen the electrochemical stability window. (3) \u003cstrong\u003eEssential Functional Interphase Additives\u003c\/strong\u003e: (i) 1.5 wt% to 2.0 wt% Fluoroethylene Carbonate (FEC): Vital for building a dense, elastic, LiF-rich SEI on the graphite anode that prevents exfoliation and continuous solvent reduction. (ii) 1.0 wt% Lithium difluoro(oxalato)borate (LiDFOB) or LiBOB: Forms a stable, protective boron- and oxalate-based passivating film (CEI) on the high-voltage NCM surface, mitigating transition-metal dissolution and surface phase transitions. (iii) 0.5 wt% Tris(trimethylsilyl) phosphite (TMSPi) or Succinonitrile (SN): Scavenges trace hydrofluoric acid (HF) and moisture, neutralizing acid-catalyzed degradation and coordinating with dissolved transition-metal ions to prevent them from poisoning the anode SEI.\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\u003eCHVLIBSEMNCMG (C-HVLIB-SE-MNCMG)\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;4.35V, NCM (Ni\u0026lt;80%, eg: NCM111, NCM523, NCM622, NCM711) + Graphite\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:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/aenm.202003738\"\u003eS.
