Before the break of the 20th century, there had been six popular versions of the dry battery in circulation. During the first World War batteries were greatly used to power torches, field radios, and most importantly the household radio. Throughout the war, battery production had increased and technology had caused it to become more advanced. The growth of this technological advancement can be contributed to the great inventors and the fast learners that have mastered the construction of the battery.
Now that we know where the battery has originated, it is important to know how the battery works. A battery consists of one or more electrochemical cells. Cells are considered the main unit of which batteries are constructed. A cell is equipped with four general components. It has a positive electrode that receives electrons from the external circuit when the cell is discharged (Anode), a negative electrode that gives electrons to the external circuit(Cathode), an Electrolyte (any substance that conducts an electric current between the anode and cathode of the battery), which provides a mechanism for charge to flow between positive and negative electrodes, and a separator, which isolates each charge. When a battery is inserted into a circuit, a charge flows around the circuit in a loopy pattern. Electrons result in electrical current on the outer part of the circuit while the charge flows in the form of ions (compounds or atoms that have either lost electrons making them positively charged or gained electrons making them negatively charged) that are moved from one electron to the other in the internal part of the cell. The positive electrode receives electrons from the external circuit on discharge. These electrons react with the positive electrode in Reduction (opposite of oxidation). At the sight of the negative electrode, Oxidation reactions between the active materials of the negative electrode and the charge flowing through the electrolyte results in surplus electrons that will be given to the external circuit.
