NMC622 Cathode Active Material Li(Ni0.6Co0.2Mn0.2)O2
NMC622 cathode material delivers an excellent balance of high capacity (≥170 mAh/g), cycle stability, and thermal safety, making it a popular choice for EV, energy storage, and power tool applications. Its intermediate Ni content (60%) provides better structural stability and lower thermal reactivity versus NMC811, with capacity above NMC532.
