NMC batteries technology and applications
In 2008, the NMC (Nickel Manganese Cobalt Oxide) battery was developed. LiaC6 serves as the anode, LibNi1–x–yCoxMnyO2 serves as the cathode, and Li+ serves as the carrier. It is frequently utilized in a variety of applications, including energy systems and electric automobiles. The best of manganese and nickel are combined in NMC. Nickel has a low stability but a high specific energy; Manganese has the ability to form a spinel structure with low specific energy and low internal resistance. The strengths of both parts are increased when the metals are joined. Power tools, energy storage systems (EES), and electrical powertrains like automobiles make extensive use of NMC batteries. Typically, the cathode composition is 1-1-1, or one third nickel, one third manganese, and one third cobalt. Due to the lower cobalt content, this lowers the cost of the raw materials.

Advantages and disadvantages of NMC batteries
The NMC batteries have the following main advantages:
NMC cells have a longer life cycle, are cheaper, and have a higher energy density. By weight and volume, NMC cathodes contain the most energy.
The following are the primary drawbacks of NMC batteries:
The disadvantage of adding silicon to graphite is that it causes the anode to expand and contract as the cell charges and discharges, resulting in mechanical instability.
less voltage than cobalt systems
