Overview
NCM811 contains 80% nickel and delivers capacity close to 200 mAh/g, making it a key route to higher cell energy density. The high nickel content brings greater surface reactivity and residual alkali, requiring coating, doping and low-dew-point handling.
- Ni ≥ 80%
- Capacity 190–200 mAh/g
- Residual alkali ≤ 0.03%, magnetic ≤ 0.3 ppm
