Question

In Ni-Cd storage cell, anode consists of:
(A) Cadmium oxide
(B) Nickel oxide
(C) Cadmium metal plate
(D) Nickel metal plate

Answer 1

Hint : To answer this question, we first need to understand what a storage cell is. A battery (storage cell) is a galvanic cell (or a group of galvanic cells) that has all of the reactants required to generate electricity. A fuel cell, on the other hand, is a galvanic cell that generates electricity with the help of a steady external supply of one or more reactants.

Complete Step By Step Answer:
Ni-Cd storage cell - Nickel–cadmium batteries (also known as Ni-Cd batteries or NiCad batteries) are rechargeable batteries that use nickel oxide hydroxide and metallic cadmium as electrodes. The acronym Ni-Cd is formed from the chemical symbols nickel (Ni) and cadmium (Cd); the acronym NiCad is a registered trademark of SAFT Corporation, though it is often used to refer to all Ni–Cd batteries.
During discharge, a Ni-Cd battery's terminal voltage is around 1.2 volts, and it doesn't drop much until towards the end. A Ni-Cd cell has a maximum electromotive force of 1.3V. Ni-Cd batteries come in a variety of sizes and capacities, ranging from small sealed cells that can be interchanged with carbon-zinc dry cells to huge ventilated cells for standby and motive power. In comparison to other types of rechargeable cells, they have a good cycle life and performance at low temperatures, as well as a reasonable capacity, but their major benefit is their ability to give nearly their entire rated capacity at high discharge rates.
Cathode – The positive or oxidizing electrode, the cathode, receives electrons from the external circuit and reduces them throughout the electrochemical reaction.
Anode - During an electrochemical process, the anode is the negative or reducing electrode that releases electrons to the external circuit and oxidizes.
So, we conclude that In Ni−Cd storage cell anode consists of Cd metal plate.
So, the final answer is option (C) i.e., Cadmium metal plate.

Note :
The electrolyte is the medium that facilitates ion transport between a cell's cathode and anode. Electrolytes are commonly conceived of as liquids containing dissolved salts, acids, or alkalis that are required for ionic conduction. Many batteries, including traditional (AA/AAA/D) batteries, do, however, contain solid electrolytes that act as ionic conductors at ambient temperature.
