NCM622 Cathode Active Material

Overview

NCM622 (LiNi₀.₆Co₀.₂Mn₀.₂O₂) is a layered oxide cathode active material widely used in lithium-ion battery research to study higher energy density performance with practical processing behaviour. During charge and discharge, lithium ions reversibly intercalate/de-intercalate within the layered structure, while transition-metal redox (predominantly Ni²⁺/Ni⁴⁺) provides the main charge compensation. This chemistry is commonly selected for benchmarking electrolyte additives, coatings, formation protocols, and impedance evolution in coin cells, pouch cells, and prototype cylindrical formats.

Key material specifications (typical quality targets)

• Particle size distribution: D10 ≥ 5.0 µm; D50 = 8.0–12.0 µm; D90 ≤ 25.0 µm
• Moisture: ≤ 0.10% (low water content supports more stable slurry and reduced side reactions)
• Impurity control: Ca ≤ 0.0200%, Cu ≤ 0.0050%, Fe ≤ 0.0100%, Na ≤ 0.0300%
• Coin-cell performance indicators: 0.5C ≥ 165 mAh/g; 1C ≥ 160 mAh/g; first efficiency ≥ 83%
  
  

Compatibility and processing notes

NCM622 is compatible with standard cathode formulations using PVDF binder in NMP, conductive carbon additives, and aluminium current collectors. For reproducible results, minimise humidity exposure and consider pre-drying before batching to reduce moisture-driven parasitic reactions.

Typical applications

• Lithium-ion cathode screening (rate capability, cycling, calendar ageing)
• Electrolyte/additive and separator evaluation
• EIS/impedance studies and degradation analysis
• Academic and industrial R&D for EV and high-energy Li-ion chemistries
