Customer ServiceThe 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.
The operating principle of a nickel-cadmium battery is the same as other batteries. To improve efficiency, nickel and cadmium are used. A battery is the source of DC voltage, hence it must consist of two potential points i.e positive and negative or also called anode and cathode.
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.
Nickel-Cadmium Battery Equations The chemical equations that represent the reaction are as follows: 2NiOOH + 2H2O + 2e" => 2 Ni (0H)2 + 2 OH Cd + 2 OH' => 2 Cd (OH)2 + 2e- 2NiOOH + Cd + 2H2O <-> 2 Ni (OH)2 + Cd (OH)2 The reaction between the cathode layer nickel and the separator is described by the first equation.
A nickel-cadmium cell has two plates. The active material of the positive plate (anode) is Ni (OH) 4 and the negative plate (cathode) is of cadmium (Cd) when fully charged. The electrolyte is a solution of potassium hydroxide (KOH) with a small addition of lithium hydrate which increases the capacity and life of the battery.
Nickel-Cadmium Battery Temperature Range During charging, the temperature range for nickel batteries is 0 to 45 degrees Celsius, and during discharging, the temperature range is -20 to 65 degrees Celsius. The battery can not work outside of this temperature range, and there is a risk of explosion.
