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.
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.
Editor’s note, 2/13/2020: Per reader requests, we have uploaded model files to go along with this blog post to the Application Gallery entry “ Potential Profile in Batteries and Electrochemical Cells “. We find out if the electric currents in batteries flow backwards by studying the potential profile inside a battery.
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?
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
When the circuit is completed, electrons flow out of the negative terminal of the battery, lose potential energy as they transit the circuit, and return to the cell at the higher potential positive terminal. This means that the direction of current determined on circuit diagrams (from (+) terminal to...

How Do Batteries Work? Parts, Types & Terminology (W/ Diagram)
With rechargeable batteries (also called secondary batteries), however, this process can be reversed by connecting the batteries to battery chargers after they die. Recharging a battery reverses the flow of electrons by using another power source. The chemical processes in the battery are able to reverse due to this added energy, and the battery will once …
