In a storage battery cell, through which medium do electrons move?

In a storage battery cell, electrons move through the electrolyte medium. The electrolyte is a substance that allows ions to move between the battery's electrodes during the chemical reactions that occur within the cell. It can be in liquid, gel, or solid form and contains ions capable of conducting electricity.

While electrons travel through the external circuit connecting the electrodes, inside the cell, it’s the ions in the electrolyte that facilitate the flow of charge. As a result, the movement of ions in the electrolyte is critical for the battery's function, enabling the transfer of electrons from one electrode to the other during discharge and recharge cycles. This is why the electrolyte is considered the medium through which electrons effectively participate in the electrochemical processes of a storage battery.
