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 an irreversible chemical reaction |
It has a 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 |
Some examples of the secondary cell.
Lithium-ion battery and nickel-cadmium.
Some examples of the primary cell.
Alkaline batteries and dry cells are examples of primary cells.
