The anode is connected to the positive side of a battery, or other power source, and the cathode to the negative side. Current flows through the electrolyte, causing nickel chloride to dissociate into positive nickel ions and negative chloride ions. The negative chloride ions are attracted to the anode, where they cause nickel to dissolve into solution. Nickel ions, in turn, are attracted to the cathode, where they coat the product.

Benefits: The benefits of nickel electroplating include improving the hardness, strength and resistance to corrosion of the product. It can also improve the brightness and external appearance of a product.
