The working of the nickel-cadmium battery is based on the chemical reaction taking place between the layers. The battery which is a source of DC voltage consists of two ports i.e. anode and cathode. While making the battery, first the cadmium layer is kept on the redox. The cadmium layer acts as the cathode terminal.
