The operating principle of nickel-cadmium batteries is based on the chemical reactions between layers. The battery, which has anode and cathode connections, is a source of direct current. When manufacturing the battery, the conductive heavy metal cadmium coating is maintained in a redox state.
The nickel–cadmium battery system still uses the same positive electrode as the nickel–iron one, while the negative electrode is cadmium. The maximum cell voltage during charge is 1.3 V, and the average cell voltage is 1.2 V. In eqns – , the cell reactions during charging and discharging are presented. At the cathode electrode,
The specific gravity of the electrolyte is 1.2. Since the voltage produced by a single cell is very low, many cells are connected in series to get the desired voltage output and then this arrangement is known as the nickel cadmium battery. In these batteries, the number of positive plates is one more than that of negative plates.
Once the battery is assembled, it is usually not opened to ensure all layers are visible and safe. When the gadget is not in use, it is advised to remove the battery to maintain safety because of the chemical processes occurring inside the battery. A schematic diagram of the nickel-cadmium battery is provided below.
The nickel–cadmium secondary battery contains NiOOH/nickel hydroxide as a positive active material, cadmium/cadmium hydroxide as a negative active material, and an aqueous solution containing potassium hydroxide as the main component as an electrolyte. Generally the charge-and-discharge reaction is shown in the following formulas 1, 2 and 3.
A metal is rolled with cadmium and separator layers and kept in redox so that the chemical reaction produces the DC voltage. Batteries have been popular for a long, and in an effort to increase the efficiency of the battery more and more chemical elements are used. This makes the construction compact.

Nickel Cadmium Battery Construction & Working
Electrical Characteristics of Nickel Cadmium Battery. The EMF of a fully charged cell is 1.4 V which decreases to 1.3 V rapidly. The average EMF of the cell is 1.2 V which reduces to 1.0 V when discharged. The internal resistance of the cell is very less, even lesser than a lead-acid battery. Due to low internal resistance these can be operated ...
