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).

Nickel (Ni): is one of the most widely used electroplating metals. Nickel plating provides excellent corrosion resistance, wear resistance, gloss and solderability. Widely used in automotive parts, bathroom hardware, electronic product shells, fasteners, etc., as decorative coatings or functional protective layers (often as the bottom layer of chrome coating). Cobalt (Co): is often added to nickel plating solution as alloy elements to improve the performance of nickel plating: improve hardness and wear resistance: used in occasions where high wear resistance is required, such as engine parts and molds. Improve high-temperature performance: Keep the coating stable at high temperatures. Get a specific look: Sometimes used to get black or dark plating (such as gun color)
