Nickel (Ni): is the core component in the positive electrode materials of ternary lithium batteries (such as NCM: nickel-cobalt manganese, NCA: nickel-cobalt aluminum). Increasing nickel content can significantly increase the battery's energy density (storage more power), thereby extending the range of the electric vehicle. It is the key direction of the current research and development of high-energy density batteries.
Cobalt (Co): It mainly plays a role in stabilizing the layered structure in ternary materials, improves the structural stability and cycle life of the material (the battery can last longer), and improves the rate performance (charge and discharge speed).
