Answer:
Explanation:
A storage battery is a device which provides a potential difference to an electric circuit.
It contains a cathode, an anode and an electrolytic solution filled between cathode and anode.
The electrolytic solution gives ions to the solutions which flows from one electrode to another and an electric current is flow inside the cell.
It means a storage batter contains large number of ions which flows and thus a potential difference is created between the electrodes of the cell.
