Question

differentiate between primary and secondary cell in points. IN POINTS​

Answer 1

Answer:

Primary cells are the ones which cannot be recharged and have to be discarded after the expiration of the lifetime whereas, secondary cells need 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.

Answer 2

Answer:

Primary cell

• Have high energy density and slow in discharge and easy to use
• There are no fluids in the cells hence it is also called as dry cells
• It has high internal resistance
• It has an irreversible chemical reaction
• Its design is smaller and lighter
• Its initial cost is cheap

Secondary cells

• They are smaller energy density
• There are made up of wet cells (flooded and liquid cells) and molten salt (liquid cells with different composition
• It has a low internal resistance
• It has a reversible chemical reaction
• Its design is more complex and heavier
• Its initial cost is high

Hope this helps, they are in a order.
