Question

What is a Nickel-Cadmium storage cell ?

Answer 1

It is a water- based cell having a Cadmium anode as well as a highly oxidized Nickel cathode. These are rechargeable cells often used in cameras, watches etc.The Nickel-Cadmium battery refers to a type of a secondary storage cell.

Complete answer:
A battery is defined as a device that consists of one or more than one electrical cell which basically converts chemical energy into electrical energy. There are majorly two kinds of battery that are mentioned below:
-Primary cell
-Secondary cell

Nickel-Cadmium Battery: The Nickel-Cadmium battery which is also referred to as the ‘NiCad’ battery is a type of rechargeable battery which utilizes Metallic Cadmium as well as Nickel Oxide Hydroxide as the electrodes of the battery. The NiCad battery is generally known for offering varying discharge rates which are particularly dependent over the size of the battery only.

Given below are the basic key features of NiCad battery:
-The nickel-cadmium battery highlights a highly rapid as well as an even discharge of the electrical energy.
-This kind of a battery is basically available and is also said to be comparatively inexpensive.
-The NiCad battery can most ordinarily be seen in toys and not only this but in small electronic devices also such as TV remotes, watches etc.

Note: The structure of NiCad battery basically maximises the area of the electrodes while minimizing the distance present between them, that in turn gives the battery both, a high discharge current as well as a high capacity. Given below is the cell reaction of the Nickel-Cadmium storage cell- $Cd(s) + 2(NiO(OH)(s) + 2({H_2}O(l) \to Cd(O{H_2}(s) + 2(Ni{(OH)_2}(s)$
