Difference Between Primary Cell and Secondary Cell

Difference Between Primary Cell and Secondary Cell

Battery or cells are referred to the parallel combination of electrochemical cells. The major difference between primary cell and secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable.

Difference Between Primary Cell and Secondary Cell

Primary cells are the ones which cannot be recharged and has to be discarded after the expiration of the lifetime whereas, secondary cells needs to be recharged when the charge gets over. Both the types of battery are used extensively in various appliances and these cells differ in size and material used in them.

Difference Between Primary Cell and Secondary Cell

Primary Cell

Secondary Cell

Have high energy density and slow in discharge and easy to use

They are smaller energy density

There are no fluids in the cells hence it is also called as dry cells

There are made up of wet cells (flooded and liquid cells) and molten salt (liquid cells with different composition)

It has high internal resistance

It has low internal resistance

It has irreversible chemical reaction

It has reversible chemical reaction

Its design is smaller and lighter

Its design is more complex and heavier

Its initial cost is cheap

Its initial cost is high
