Question

What is primary cell and secondary cell ? Give one example?

Answer 1

Primary Cells : Primary batteries are single-use galvanic cells that store electricity for convenient usage, usually showing a good shelf life.

Secondary Cells : Secondary cells, the reactions can be reversed by an external electrical energy source

Answer 2

Answer:

A primary cell is a disposable, non-rechargeable, single-use cell.

For example-Dry cells such as alkaline cell

A secondary cell is an electric, rechargeable cell.

For example-Lithium-ion batteries

Explanation:

A cell or battery is an electrochemical cell or series of cells that produce an electric current. These are of two types:

1. Primary cell

• It is a cell or battery that completes its cell reactions and becomes dead after some time. Such cells cannot be used after completing the battery life. They contain solid or molten electrolytes and thus are known as dry cells.

• For example-Alkaline cells, Lithium cells, Mercury cells

2. Secondary cell

• It is that type of cell or battery that can be reused just by charging for some time. This can be electrically recharged many times to use after its pre-discharge condition which increases the battery life.

• For example- Ni-Cd cells, lithium-ion cells, Lead-acid cells
