Figure 9.3.2 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.
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.
Figure 9.3.3 9.3. 3 illustrates the flow of charges when the battery is charging. During charging, energy is converted from electrical energy due to the external voltage source back to chemical energy stored in the chemical bonds holding together the electrodes. Again, the flow of both electrons and ions, not just electrons, must be considered.
During battery discharge, current flows from the positive electrode to the negative electrode. This flow happens because of a potential difference. The battery converts stored energy to usable energy in the circuit. Ohm’s law shows that current relates to the electric field, guiding the flow direction based on electric potential differences.
While the chemical reaction can often go in either direction, the package and structure of a primary battery are not designed to withstand the charging process and will typically be damaged [128, ch. 5.1]. Figure 9.3.2 9.3. 2: Charge flow in a discharging battery.
Heat, voltage, and charge cycles affect performance. Charging uses CC-CV methods to prevent overcharging. Discharging below 3.0V damages capacity, shortening battery life. Need expert guidance on lithium-ion battery charging and discharging?
