Lithium Ion Secondary Battery Cathode Material Lithium Nickel Cobalt Manganese Oxide

Product Overview

This premium lithium nickel cobalt manganese oxide (NMC) cathode material delivers a balanced electrochemical profile designed for next-generation energy storage systems. Formulated with a balanced ternary transition-metal matrix, the powder provides an optimal synergy between high specific capacity, thermal robustness, and extended cyclic durability. Strict stoichiometric control ensures consistent phase purity and stable structural transitions during repetitive lithium intercalation and deintercalation cycles, minimizing capacity degradation in high-rate operational regimes.

Engineered specifically for lithium-ion secondary cell fabrication, this cathode powder is suited for electric vehicle (EV) battery packs, grid-scale energy storage solutions (ESS), consumer electronic cells, and advanced electrochemical research laboratories. The powder integrates seamlessly into industrial aqueous or solvent-based slurry formulations, ensuring homogenous coating rheology and superior adhesion on aluminum current collectors across diverse pilot and automated production lines.

Manufactured under rigorous cleanroom conditions and comprehensive quality assurance protocols, this material demonstrates exceptionally low magnetic and transition-metal contaminant levels. High chemical stability, controlled moisture absorption, and minimal residual surface lithium guarantee extended slurry pot life and reduced gas generation during high-voltage cycling, providing engineers and researchers with dependable, reproducible results in demanding industrial and scientific environments.

Key Features

• Precise Stoichiometric Transition Metal Balance: Rigorously controlled ICP elemental composition (Ni: 20.60±1.00%, Co: 21.00±1.00%, Mn: 16.60±1.00%, Li: 7.3~7.9%) guarantees stable layered crystalline structures and superior electrochemical reversibility over prolonged cycling.
• Optimized Particle Size Distribution: Narrow laser diffraction profile with D10 ≥ 2.5 µm, median D50 of 7.5 ± 1.0 µm, and D90 ≤ 16 µm enables close packing during calendering, achieving excellent volumetric energy density without localized current crowding.
• High Tap Density and Compaction Performance: A verified tap density of ≥ 2.2 g/cm³ facilitates the fabrication of dense, high-loading electrode coatings, enhancing the gravimetric and volumetric efficiency of secondary pouch, cylindrical, and prismatic cells.
• Ultra-Low Residual Soluble Lithium: Free lithium dissolution capped at ≤ 0.25% (measured via automatic potentiometric titration) prevents slurry gelation, minimizes gas swelling during cell formation, and enhances shelf-life stability.
• Controlled Surface Area for Enhanced Kinetics: A stable BET specific surface area between 0.25 and 0.45 m²/g offers optimal electrolyte wetting and rapid charge-transfer kinetics while reducing undesirable parasitic side reactions at elevated operating potentials.
• Strict Impurity and Trace Metal Suppression: Stringent ICP-verified thresholds for Fe (≤ 30 µg/g), Cu (≤ 20 µg/g), Zn (≤ 20 µg/g), and S (≤ 3500 µg/g) safeguard cells against internal micro-short circuits and self-discharge phenomena.
• Low Moisture and Controlled Alkalinity: Karl Fischer moisture testing confirms water content ≤ 500 µg/g with a strictly regulated pH (≤ 12), ensuring flawless binder compatibility (e.g., PVDF in NMP) without phase separation or premature cross-linking.
• Hazardous Substance Regulatory Compliance: Fully compliant with the electronic information products environmental standard SJ/T 11363-2006, ensuring eco-conscious and safe handling for industrial manufacturing and global export compliance.
