Analyzing the energetics of the overall cell reaction can also provide insights into how commercial batteries work and where their energy is stored. The most widely used household battery is the 1.5 V alkaline battery with zinc and manganese dioxide as the reactants. Six 1.5 V cells are also combined in series to produce a 9 V battery.
Working principle of basic battery in the discharge mode (Galvanic element). Spontaneous redox processes at the electrodes result in electric current through the circuit. In the charge mode (electrolytic cell), electricity-driven redox processes take place at the electrodes resulting in reversal of the spontaneous process.
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT’s Department of Materials Science and Engineering.
All batteries cells are based only on this basic principle. Let’s discuss one by one. As we said earlier, Alessandro Volta developed the first battery cell, and this cell is popularly known as the simple voltaic cell. This type of simple cell can be created very easily. Take one container and fill it with diluted sulfuric acid as the electrolyte.
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the dynamo in your car) can be applied to the chemical system, and reverse its operation, restoring the battery’s charge.
