{"product_id":"chvlibselcog","title":"Specific Electrolyte for High-Voltage Lithium-Ion Battery {≥4.5V LiCoO2 + Graphite}, 200 g\/bottle, CHVLIBSELCOG","description":"\u003cp\u003eOperating a lithium-ion cell with a Lithium Cobalt Oxide (LiCoO2 \/ LCO) positive electrode charged to ~ 4.5 V paired with a Graphite (Gr) negative electrode unlocks high volumetric energy densities (~ 180-190 mAh\/g practical LCO capacity). However, standard carbonate electrolytes (such as 1 M LiPF6 in EC\/EMC) undergo aggressive oxidative decomposition at the high-potential LCO surface, causing severe cobalt dissolution, surface phase transitions, and gas evolution. To achieve stable cycling under these harsh conditions, advanced high-voltage electrolyte engineering relies on Localized High-Concentration Electrolytes (LHCE) or functionalized multi-additive carbonate systems designed to build a robust, inorganic-rich Cathode Electrolyte Interphase (CEI) and Solid Electrolyte Interphase (SEI).\u003c\/p\u003e\n\u003cp\u003eThe Localized High-Concentration Electrolyte (LHCE) Strategy: \u003cstrong\u003ePrimary Salt\u003c\/strong\u003e: 1.0 M to 1.2 M Lithium bis(fluorosulfonyl)imide (LiFSI) or LiPF6. \u003cstrong\u003eCo-Solvent \/ Primary Complexing Matrix\u003c\/strong\u003e: Dimethyl Carbonate (DMC) or Ethyl Methyl Carbonate (EMC) with minimal Ethylene Carbonate (EC) to reduce parasitic oxidation. \u003cstrong\u003eInert Fluorinated Diluent\u003c\/strong\u003e: 1,2-bis(1,1,2,2-tetrafluoroethoxy)ethane (TFEE \/ HFE-578E) or 1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether (TTE) added in a high volume ratio (e.g., 1.2:2.8 salt-solvent complex to diluent). The diluent does not coordinate with Li+, forcing an anion-rich inner solvation sheath. Upon electrochemical formation, this yields an inorganic-rich CEI (packed with LiF and sulfur-oxygen species) that passivates the 4.5 V LCO surface against transition metal leaching and structural collapse.\u003c\/p\u003e\n\u003cp\u003eIf utilizing a conventional carbonate solvent framework for cost and viscosity optimization, a heavily additized standard formulation is required: \u003cstrong\u003eMain Salt\u003c\/strong\u003e: 1.0 M LiPF6; \u003cstrong\u003eSolvent Base\u003c\/strong\u003e: Ethylene Carbonate (EC) + Ethyl Methyl Carbonate (EMC) (3:7 by weight); \u003cstrong\u003eFunctional Additives\u003c\/strong\u003e: (i) 2.0 wt% Fluoroethylene Carbonate (FEC) that is essential for generating a protective, elastic SEI on the graphite anode and contributing to fluoride-based CEI stabilization.
