One of the most successful lithium ion systems is the cathode combination of nickel-manganese-Cobalt (NMC). Like lithium manganate, the system can be customised for use as an energy or power battery. For example, the NMC in the 18650 battery under moderate load has a capacity of about 2,800mAh and can provide 4A to 5A discharge currents. The same type of NMC, optimized for a specific power, has a capacity of only 2,000mAh but provides a continuous discharge current of 20A. The silicon anode will reach above 4000mAh, but the load capacity will be reduced and the cycle life will be shortened. The silicon added to graphite has a defect, that is, the anode expands and contracts with charging and discharging, which makes the structure of the battery with high mechanical stress unstable.
The NMC’s secret lies in the combination of nickel and manganese. Nickel is known for its high specific energy, but its stability is poor. Manganese spinel structure can achieve low internal resistance but low specific energy. The two active metals complement each other.
The NMC cathode has good overall performance and performs well in specific energy. This battery is the first choice for electric vehicles with the lowest self heating rate.
NMC hybrid lithium ion battery has been paid more and more attention due to its good economic performance and comprehensive performance. The three active materials – nickel, manganese and cobalt – can be easily mixed to suit a wide range of applications requiring frequent cycling in vehicles and energy storage systems (EES). The diversity of the NMC family is growing.is
