Summary
"Batteries run on chemical reactions within them. They contain one or more cells, which consist of electrodes (anode and cathode) submerged in an electrolyte solution. The chemical reactions between the electrodes and electrolyte generate electrons, creating an electric current. In simple terms, when a device is connected to a battery, the flow of electrons from the cathode to the anode powers the device. The types of chemical reactions and materials used in batteries may vary, resulting in different battery chemistries such as alkaline, lithium-ion, or lead-acid, each with its own characteristics and applications."
