Primary Cell and Secondary Cell

A Cell or Battery is an electrical battery or cell is a component that converts Chemical Energy into Electrical Energy.

 Both Cell and Battery are the same combination of electroChemical Cells. The Cell is a simple and small unit. Many Cells make up a Battery and therefore, the Battery is called a cluster of Cells. The Cell is relatively small in size than the Battery.

TYPES:

There are mainly two types of Cell. This is briefly discussed below.

1 Primary Cell:

 In the first Cell electrical Energy is generated using an irreversible Chemical reaction. Rechargeable Cells come out slowly. They are very intertwined. Because of the lack of fluid in the Cell, it is also called a dry Cell. Although easy to use, they cannot be reused. In general, they have very high internal opposition. They are found on the lower costs.

2 Secondary Cell:

 Secondary regenerative Cells convert Chemical Energy into electrical Energy and vice versa. They are charged again by the power supply. They are made up of water Cells and molten salt. There is low internal resistance in this Cell. They are relatively inexpensive to use than the main Cell. They cost more than a basic Cell.A Battery or Cell is referred to as a compatible combination of electroChemical Cells. 

3 The main difference between the Primary Cell and the Secondary Cell

The main difference between the Primary Cell and the Secondary Cells is that the Primary Cells are the ones that can be charged whereas the Secondary Cells are the ones that cannot be charged.Primary CellPrimary Cells have a large volume and are leaky. Since there is no fluid inside these Cells it is also known as dry Cells. Internal resistance is high and Chemical reactions cannot be reversed. Its initial cost is cheap and basic Cells are easy to use.The Secondary CellSecondary Cells have a small amount of Energy and are made up of molten salt and water Cells. Internal resistance is low and Chemical reactions are reversed. Its initial cost is high and a little more complicated to use compared to the main Cell.The Difference Between a Basic and a Secondary CellPrimary Cells are the only ones that can be charged and need to be discarded after the end of the life span, while Secondary Cells need to be recharged once the charging is complete. Both types of batteries are widely used in a variety of applications and these Cells vary in size and material.S.No. Primary Cell Secondary  Cell These cannot be recharged again after getting discharged once.  These can be recharged easily. These are cheap or low cost. These are expensive compare to Primary Cell. These are easy to use. These are difficult to use in comparison to Primary Cell. These can be used only once. These can be used more than once. In these Cells irreversible reactions occur. In these Cells reversible reaction occurs. These have a lower self-discharge rate. These have a higher self- discharge rate. These are used in torch and other portable devices as they produce electric current immediately. These are used in inverters and automobiles. These Cells don’t require regular maintenance and can be disposed of easily after use. These Cells require regular maintenance. They have a low or small lifetime. They have a high lifetime. Examples of these Cells are dry Cells, Daniel Cells etc. Examples of these Cells are lead-acid Cell, nickel – iron Cell etc. 

Conclusion:

All batteries are made of electroChemical Cells. Primary and Secondary Cells are two types of batteries that are useful for everyday life. The only difference is that Primary Cells are used for a shorter duration and more Energy is stored in Secondary Cells.
