NMC materials have layered structures similar to the individual metal oxide compound lithium cobalt oxide (LiCoO₂).During discharge, lithium ions intercalate between the layers, staying within the lattice planes. When the battery charges, the lithium ions de-intercalate and migrate to the anode.

Points in a solid solution phase diagram between the end members LiCoO₂, LiMnO₂, and LiNiO₂ represent stoichiometric NMC cathodes. Three numbers immediately following the NMC abbreviation indicate the relative stoichiometry of the three defining metals. For example, an NMC molar composition of 33% nickel, 33% manganese, and 33% cobalt would abbreviate to NMC111 (also NMC333 or NCM333) and have a chemical formula of LiNi _0.33Mn_0.33Co _0.33O₂. A composition of 50% nickel, 30% manganese, and 20% cobalt would be called NMC532 (or NCM523) and have the formula LiNi_0.5Mn_0.3Co_0.2O₂. Other newer common compositions are NMC622 and NMC811. The general lithium content typically remains around 1:1 with the total transition metal content, with commercial NMC samples usually containing less than 5% excess lithium.

For NMC111, the ideal oxidation states for charge distribution are Mn⁴⁺, Co³⁺, and Ni²⁺. Cobalt and nickel oxidize partially to Co⁴⁺ and Ni⁴⁺ during charging, while Mn⁴⁺ remains inactive and maintains structural stability. Modifying the transition metal stoichiometry changes the material’s properties, providing a way to adjust cathode performance. Most notably, increasing the nickel content in NMC increases its initial discharge capacity, but lowers its thermal stability and capacity retention. Increasing cobalt content comes at the cost of replacing either higher-energy nickel or chemically stable manganese while also being expensive.

Oxygen can generate from the metal oxide at 300 °C when fully discharged, degrading the lattice. Higher nickel content decreases the oxygen generation temperature while also increasing the heat generation during battery operation. Cation mixing, a process in which Li⁺ substitutes Ni²⁺ ions in the lattice, increases as nickel concentration increases as well. The similar size of Ni²⁺ (0.69 Å) and Li⁺ (0.76 Å) facilitates cation mixing. Displacing nickel from the layered structure can alter the material’s bonding characteristics, forming undesirable phases and lowering its capacity.

Researchers recognize that the crystallinity, particle size distribution, morphology, and composition significantly influence the performance of NMC materials. They adjust these parameters by employing different synthesis methods. The first report of nickel manganese cobalt oxide described the coprecipitation method, which remains widely used today. This method involves dissolving the desired amount of metal precursors together and then drying them to remove the solvent. This material is then blended with a lithium source and heated to temperatures up to 900 °C under oxygen in a process called calcination. Hydroxides, oxalic acid, and carbonates are the most common coprecipitation agents.

Sol–gel methods are another common NMC synthesis method. In this method, researchers dissolve transition metal precursors in a nitrate or acetate solution and then combine them with a lithium nitrate or lithium acetate and citric acid solution. They stir this mixture and heat it to about 80 °C under basic conditions until a viscous gel forms. Afterward, they dry the gel at around 120 °C and calcine it twice—first at 450 °C and then at 800–900 °C—to produce NMC material.

Hydrothermal treatment can be paired with either the coprecipitation or sol–gel routes. It involves heating the coprecipitate or gel precursors in an autoclave. The treated precursors are then filtered off and calcined normally. Hydrothermal treatments before calcination improves the crystallinity of NMC, which increases the material’s performance in cells. However, this comes at the cost of longer material processing times.

Conclusion

2-NMC is a synthetic compound related to the cathinone family, notable for its structural similarities to other stimulants. While it holds relevance in analytical and forensic research, it is not intended for human consumption. Understanding its properties and related compounds is essential for researchers and forensic professionals working in the field of synthetic stimulants.
