As shown in the figure, the direction of current flow is opposite to the direction of electron flow. The battery continues to discharge until one of the electrodes is used up [3, p. 226]. Figure 9.3.3: Charge flow in a charging battery. Figure 9.3.3 illustrates the flow of charges when the battery is charging.
Figure 9.3.2: Charge flow in a discharging battery. As a battery discharges, chemical energy stored in the bonds holding together the electrodes is converted to electrical energy in the form of current flowing through the load. Consider an example battery with a magnesium anode and a nickel oxide cathode. The reaction at the anode is given by
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.
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential. But what happens inside the battery?
