Nickel Cobalt Manganese NCM622-B (Single Crystal)

This product is designed for advanced lithium-ion battery research, specifically as a single-crystal nickel cobalt manganese (NCM622) cathode material with a molar ratio of 6:2:2. Its well-controlled particle size distribution, featuring a D50 around 3.9 μm and a specific surface area of approximately 0.95 m²/g, supports consistent electrode processing and enhances structural stability. Electrochemical characterization in a coin cell configuration demonstrates an initial discharge capacity of ≥170 mAh/g and a first-cycle efficiency exceeding 81%, indicating good capacity utilization. The single-crystal morphology is intended to improve cycling performance and reduce gas generation compared to polycrystalline alternatives. Common research applications include evaluation in high-energy-density lithium-ion cells, cathode formulation optimization, and degradation mechanism studies. An NCM-specific electrolyte is recommended for optimal performance. The material is available in multiple quantities to accommodate laboratory-scale testing needs.
