What is NCM Battery?

NCM battery, also known as the “Ternary lithium battery,” incorporates nickel, cobalt, and manganese in its cathode composition. Increased nickel levels pose challenges by making Li+ removal more difficult, leading to reduced capacity and cycling. Higher nickel content results in an unstable Ni3+ proportion, intensifying reactions with moisture and CO2, thereby impacting overall performance. The term “ternary” originates from the three cathode metals: nickel (Ni), cobalt (Co), and manganese (Mn). Varied ratios, such as 1:1:1, 5:2:3, and 8:1:1, create distinct compounds, forming the basis for the fixed compound materials in Ternary lithium batteries.

Why we use Ni, Co and Mn in ternary lithium battery ?

Nickel (Ni) exhibits low reactivity at room temperature, hindering oxidation in air. The presence of Ni ions contributes to a higher volumetric energy density.

Cobalt (Co) remains stable in humid air and is unreactive with water at room temperature. Despite its relatively high cost, the laminar structure of the material enhances stability, reduces impedance values, and improves conductivity and cycling performance through the presence of Co ions.

Manganese (Mn) is inherently stable, resistant to oxidation or reduction. The inclusion of Mn ions enhances material safety and stability.
