Manganese, which has an oxidation state of +4 is detrimental towards ionic conductivity as it interferes with the charge carriers. However, it stabilizes the structure as a whole and improves cyclic stability. The NMC chemistry can be considered as a balancing act between the advantages and disadvantages of lithium cobalt oxide, lithium manganese oxide and nickel oxide thereby leading to higher capacity and better cyclic stability. The major problems associated with NMC are that phase transformations are occurring in the material, the effect of the mixed population (Ni, Co, Mn) on the lithium positions leading to a high irreversible capacity, possibility of oxygen evolution during charging. Another problem is that it has a lower discharge voltage (3.7V) vs Li/Li+ as compared to 3.9V of LCO. Increasing the nickel content has been studied to improve the usable capacity to 190 mAh/g . NMC 442 and NMC 922 have shown that with a slight increase in lithium and manganese concentration, the discharge capacity can be improved marginally while retaining good rate capability. This has led to an effective decrease in cobalt concentration . Batteries with NMC cathode with Si anode have been predicted to be a future game-changer in the domain of electric mobility .
