How to Discharge a Bettery ?

Charging and Discharging Definition

Charging is the process of restoring a battery’s energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions.

Oxidation Reaction

Oxidation happens at the anode, where the material loses electrons.

Reduction Reaction

Reduction happens at the cathode, where the material gains electrons.

Discharging of Battery

In a battery there are two electrodes immersed in an electrolyte. When an external load is connected to these two electrodes, oxidation reaction starts occurring in one electrode and at the same time reduction occurs in other electrode.

Charging of Battery

The external DC source injects electrons into the anode during charging. Here, reduction takes place at the anode instead of the cathode. This reaction allows the anode material to regain electrons, returning to its original state before the battery discharged.

Electron Flow in Discharge

During discharging, electrons flow from the anode to the cathode through an external circuit.

Role of External DC Source in Charging

An external DC source is used in charging to reverse the discharging reactions, restoring the battery to its charged state.
