By balancing nickel content for enhanced energy density with cobalt and manganese for structural and thermal robustness, the material supports high-rate charge-discharge profiles while maintaining low interfacial polarization and long calendar life.

Manufactured in strict accordance with the YS/T 798-2012 industrial standard, this cathode powder guarantees batch-to-batch consistency and trace impurity control. Every batch undergoes rigorous quality assurance—including ICP elemental analysis, laser diffraction particle sizing, and precision coin-cell cycling—ensuring dependable electrochemical execution under demanding operating conditions.

Key Features

• Optimized 6:2:2 Stoichiometric Balance: Precision transition metal formulation (LiNi0.6Co0.2Mn0.2O2) delivers a typical initial discharge capacity of 187 mAh/g with an initial Coulombic efficiency of 88%, maximizing gravimetric energy density.
• Controlled Particle Size Distribution: A tightly managed median particle diameter (D50 of 4.0 ± 1.0 µm) provides high particle packing density, smooth electrode slurry rheology, and uniform current distribution across the coated foil.
• Low Residual Surface Alkali: Stringent process controls limit residual LiOH to ≤0.20 wt% and Li2CO3 to ≤0.20 wt%, preventing slurry gelation during processing and significantly reducing gas generation during high-voltage cell cycling.
• Superior High-Rate Discharge Kinetics: Demonstrates robust power capability with typical coin-cell discharge capacities of 166.2 mAh/g at 0.5C and 162.3 mAh/g at 1.0C (2.75V–4.3V vs. Li/Li+).
• High Compaction Density Potential: Engineered to achieve calendar roll compaction densities between 3.20 g/cm³ and 3.40 g/cm³, enabling ultra-dense electrode coatings without inducing secondary particle pulverization.
• Ultra-Low Trace Impurities: Controlled heavy metal and alkali contamination (Fe ≤ 0.0100%, Cu ≤ 0.0050%, Ca ≤ 0.0200%, Na ≤ 0.0300%) ensures low cell self-discharge rates and protects against micro-short circuits.
• Excellent Full-Cell Compatibility: Specifically configured to deliver a stable design capacity of 163 mAh/g at 0.5C (3.0V–4.2V operating window) when paired with conventional synthetic and natural graphite anodes.
• Agglomerate-Free Powder Quality: Fully de-agglomerated gray-black powder guarantees high dispersion uniformity in standard organic solvents (NMP) using conventional PVDF binders and conductive carbons.
