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.
The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.
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. What is a Nickel-Cadmium Battery?
Ni–Cd batteries contain between 6% (for industrial batteries) and 18% (for commercial batteries) cadmium, which is a toxic heavy metal and therefore requires special care during battery disposal. In the United States, part of the battery price is a fee for its proper disposal at the end of its service lifetime.
It is therefore usual to specify that a nickel–cadmium battery in a PV system has a maximum DOD of 90%. Industrial nickel–cadmium batteries used in PV systems are normally of the open type designed for standby use at low discharge rates. They may be of the pocket-plate or fibre-plate type.
