Nickel

Nickel (Ni) is a transition metal element, widely used in cathode materials, especially in ternary materials of lithium-ion batteries (NMC, NCA), where it plays an important role. Its addition can significantly improve the energy density and capacity of batteries, and is one of the key raw materials for high-performance electric vehicle batteries.
The role of nickel in batteries: Enhancing capacity: Nickel can significantly increase the reversible capacity of the cathode, thereby enhancing the energy density of the entire battery pack. Reducing cobalt usage: Through high-nickel design (such as NMC 811), the usage of expensive cobalt can be reduced, controlling costs. Affecting thermal stability: Although the increase in nickel content enhances energy density, it may also reduce the thermal stability of the battery, requiring the use of a better thermal management system.
