NCM622 Cathode Material with High Capacity and Stability

A rich-nickel battery cathode material for high powder Li-ion batteries

Overview | Product Information | Related Products | Technical Support

NMC622 is named after the composition ratio of nickel, manganese and cobalt as 6:2:2. Being a nickel-rich cathode material, it displays greater capacity extracted at the same potential and improved stability, compared to low-nickel NMC cathode materials.

NMC622 can be further modified with an ultra-thin CeO₂ coating. The modification overcomes the H2/H3 phase transition, reducing Ni/Li mixing and leading to a long battery life. At the end of the 50th cycle test, ceria-coated NMC622 gains 14% capacity while pristine NCM622 loses 18% of its initial capacity. This behavior indicates activation for efficient Li diffusion, mediated by enhanced the electronic interaction between ceria and NMC.

This material has also demonstrated good oxygen evolution reaction activity in 1 M KOH solution. It shows an overpotential of 280 mV to pass 100 mA·cm⁻² and a low Tafel slope of 42 mV·dec⁻¹.
