High capacity Long cycle NMC811 With Ni Content 83% For Li Ion NMC Battery Cathode
1. M2-C material characteristics
High capacity:
By increasing the nickel content of the material, using pure oxygen preparation process, and surface post-treatment process, the discharge capacity of the M2-C material is significantly improved, and the discharge capacity of 0.1C button is 210mAh/g.
Long cycle:
Through the special doping and coating technology, the structural stability of the M2-C material is significantly improved, and the cycle performance of the material is effectively improved. The 45°C button cell 0.5C/1C: 97%@50cls.
Easy processing:
Use surface coating materials to reduce surface alkali content to meet the processing performance of the material under different conditions.

Recommendations:
1. Adjust the cathode design compaction according to the cathode surface density. If the surface density is 400-480g/m2, the recommended compaction is 3.3-3.4g/cm3
2. The anode is matched with graphite, and the gram capacity of the cathode is recommended to be between 188-192mAh/g
3. Reference electrolyte Xinzhoubang high nickel electrolyte
