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.
The theoretical capacity of cadmium metal is 480 mAh g −1. However, cadmium is not usually applied as a metal to form a battery anode. The cadmium electrode may be formed starting with a mixed cadmium hydroxide, and/or cadmium oxide and a certain amount of cadmium powder. Two types of cadmium electrode are also widely used.
A method for manufacturing a common pasted-type electrode for use in the cadmium negative electrode includes mixing a cadmium oxide activate material and PVA or the like with ethylene glycol to form a paste, applying the paste to a nickel-plated perforated iron sheet, and then drying the same to form a plate.
In a NiCd battery, nickel oxide hydroxide is used to make the cathode, and the anode is made from metallic cadmium. An aqueous alkali solution is used as the electrolyte between the two electrodes. NiCd batteries are currently widely used for portable electronics applications, like lead-acid and lithium-ion batteries.
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.
The energy density of nickel-cadmium batteries is high. Also, these are lighter and more compact. Therefore, these are preferred in applications where weight and size of the battery are very important like in airplanes and helicopters. There these are used to start the engine.
