Key Features

• High Initial Coulombic Efficiency: Delivers a first-cycle efficiency of $\ge 96.0%$ in coin cell testing (vs. Li, 0.1C, 3.0V–4.3V), minimizing irreversibly trapped active lithium and maximizing usable energy output in balanced full-cell designs.
• Superior Specific Discharge Capacity: Demonstrates a high reversible discharge capacity of $\ge 157\text{ mAh/g}$ at 0.1C and $\ge 151\text{ mAh/g}$ at 1C (3.0V–4.3V), ensuring robust energy delivery and excellent rate capability under dynamic load profiles.
• Optimized Particle Size Distribution: Features a tight, monomodal granulometric profile ($D_{10} \ge 5.5,\mu\text{m}$, $D_{50} = 11.00\text{--}14.00,\mu\text{m}$, $D_{90} \le 30.0,\mu\text{m}$) that facilitates dense particle packing, smooth slurry rheology, and defect-free electrode foil coating.
• High Compacted Density Window: Supports high-pressure electrode calendering up to $4.05\text{--}4.20\text{ g/cm}^3$, enabling battery developers to attain industry-leading volumetric energy densities in compact cell designs.
• Low Residual Surface Lithium: Stringently controlled surface residual lithium ($Li_2CO_3 \le 0.08%$) and a stable alkaline threshold ($\text{pH} \le 11.00$) suppress PVDF slurry gelation and significantly reduce gas evolution during cycling and high-temperature storage.
• Ultra-Low Magnetic Contaminant Levels: Limits ferromagnetic foreign substances to $\le 300\text{ ppb}$ and trace metallic impurities (Fe, Cu, Ca, Na) to $\le 0.0200%$, drastically reducing internal micro-short circuits and self-discharge rates.
• High Tap Density: Achieves a tap density of $\ge 2.4\text{ g/cm}^3$ with a specific surface area (BET) of $0.18 \pm 0.100\text{ m}^2/\text{g}$, optimizing binder consumption and solvent loading during slurry formulation.
• High-Purity Stoichiometric Formulation: Maintains strict chemical precision with lithium content at $6.80\text{--}7.20%$ and cobalt content at $59.00\text{--}61.00%$, providing uniform crystal lattice integrity and extended electrochemical reversibility.
