This type of battery was developed as an improvement over Nickel-Cadmium (Ni-Cd) batteries, offering higher energy density and reduced environmental impact. Nickel–metal hydride batteries store more energy than nickel–cadmium batteries. The negative electrode, which is a metal hydride mixture, consists of the potassium hydroxide electrolyte
Constructional, the nickel-cadmium battery is the same as lead acid-based batteries. It consists of three fundamental layers. The first one is a nickel layer, then the separator layer, and the cadmium layer. The nickel acts as a positive electrode collector and the cadmium layer acts as a negative layer collector.
The nickel–cadmium (Ni–Cd) battery consists of an anode made from a mixture of cadmium and iron, a nickel-hydroxide (Ni (OH) 2) cathode, and an alkaline electrolyte of aqueous KOH. Ni–Cd batteries have an operating voltage of 1.2 V and are used in digital cameras, laptops, calculators, medical devices, space applications, etc. [1].
Ni-Cd batteries consist of several key components, including the positive electrode (nickel oxide hydroxide), the negative electrode (cadmium), and an alkaline electrolyte solution. The positive and negative electrodes are separated by a porous membrane, which allows the flow of ions while preventing direct contact between the electrodes.

A Nickel Cadmium Battery is a type of rechargeable battery that contains a nickel electrode coated with reactive nickel hydroxide and uses potassium hydroxide as the cell electrolyte. These batteries have higher energy densities, are lighter than lead-acid batteries, and cool down during recharging, allowing for quick charging times.
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. The specific gravity of the electrolyte is 1.2.
The active material on the positive electrode of the Nickel-cadmium Battery is composed of nickel oxide powder and graphite powder. The graphite does not participate in the chemical reaction, and its main function is to enhance the conductivity. The active material on the negative electrode plate is composed of cadmium oxide powder and iron oxide powder.

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.
The nickel-cadmium batteries are secondary cells since the chemical reaction is reversible and the cell can also be recharged as a result. The cathode (positive plate) of a Ni-Cd battery is built of nickel oxide hydroxide, and the electrode anode negative plate) is made of metalliccadmium.
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.
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.
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.
