In NMC-111 to maintain structural integrity only 66% of the lithium in the structure can be used, thus NMC gives us a gravimetric capacity of 160 mAh/g compared to the theoretical capacity of 274 mAh/g . The cobalt in the NMC structure contributes to good electrical conductivity and electrochemical performance. It further prevents nickel-lithium site mixing and its associated structural distortion.
