Part 1. What is an NMC lithium-ion battery?

NMC lithium batteries are widely used in the automotive industry. This is because they store large energy in a small mass. The combination of nickel, cobalt, and manganese is responsible for the high energy storage capacity of lithium NMC. Nickel provides high specific energy to the battery but is less stable. Manganese provides thermal stability. So, it lessens overheating during charging and discharging. Cobalt is used in lithium NMC batteries to reduce cathode corrosion. However, cobalt is expensive and harmful to the environment. So, many manufacturers are trying to reduce cobalt in NMC batteries.

Part 2. Main Parts of the NMC lithium-ion battery

It consists of three main parts. These are the cathode, anode, and electrolyte. These parts work together. So, they allow the movement of lithium ions during charging and discharging cycles.

  1. Cathode: The cathode comprises nickel, manganese, and cobalt. These three materials are used in different concentrations based on the battery design.
  2. Anode: Like all other lithium batteries, the anode is constructed from graphite. Graphite allows the storage and release of lithium ions while the battery is working.
  3. Electrolyte: The electrolyte consists of lithium ions dissolved in a liquid. The electrolyte composition varies in different batteries. The most commonly used lithium salts in electrolytes are lithium hexafluorophosphate (LiPF6) and lithium bis (trifluoromethyl sulfonyl)imide (LiTFSI). They are dissolved in organic solvents. The organic solvents that are frequently used are ethylene carbonate (EC), dimethyl carbonate (DMC), and diethyl carbonate (DEC).

Part 3. How Does a Lithium NMC Battery Work?

You might wonder how the lithium NMC battery works. Like all other batteries, it works on the principle of electrochemical reactions. It is a secondary battery. The lithium ions flow via electrolyte from the positive to the negative electrode during charging. During discharging, the ions move from the negative electrode (anode) to the positive electrode(cathode). Hence, it supplies energy to power devices such as electronic cars.

NMC Lithium-ion battery charging

During charging, the battery undergoes the following reaction:

At Negative Plate Anode (C6):

Here is the general reaction that occurs at the anode.

 C6+ xLi + e^− → LiC6

This reaction results in the formation of Lithium carbide (1/6) graphite intercalation compound.

At Positive Plate Cathode (LiNiMnCoO2):

So, the following is the reaction that is usually carried out at the cathode.

LiCoO2​ → Li1−x​CoO2​ + xLi + e^-

So, we can say the overall reaction that takes place during the charging of the battery is as follows.

LiCoO2​ + C6 → Li1−x​CoO2​ + LiC6

Overall, during charging, electrons move from cathode to anode. The result of the reaction is a lithium graphite intercalation compound.

NMC Lithium-ion battery discharging
The chemical reactions that occur during discharging are:

At Negative Plate Anode (C6):

LiC6 → C6+ xLi + e^−

At Positive Plate Cathode (LiNiMnCoO2):
 Li1−x​CoO2​ + xLi + e^- → LiCoO2​

So, the overall reaction during discharging is:

Li1−x​CoO2​ + LiC6 → LiCoO2​ + C6

x in the following reaction is a stoichiometric variable. It indicates the amount of lithium ions dissolved in the reaction. Hence, the overall discharging of the battery releases energy. This energy is provided to the electrical devices.
