Today, we learned current battery technologies at the factory. The battery is a device that converts chemical energy into electric energy multiple times through an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another. My director challenged me by asking what the differences between the battery and cell battery. In understanding the differences between a cell and a battery, one should think of a battery as one or more of these cells connected in series, or parallel, or both, depending on the desired output voltage and capacity. Then, another professional from …
