How Do Batteries Work?
Batteries are devices that store and release electrical energy in a controlled manner. They consist of two or more electrochemical cells that convert stored chemical energy into electrical energy. The basic components of a battery are the positive electrode (anode), the negative electrode (cathode), and the electrolyte.
When a battery is connected to an electrical circuit, electrons flow from the negative electrode to the positive electrode through the external circuit. This flow of electrons creates an electric current. At the same time, chemical reactions occur within the battery that produces electrons at the negative electrode and removes electrons from the positive electrode.
As the battery discharges, the electrolyte reacts with the electrodes to produce positively charged ions that move from the anode to the cathode and negatively charged ions that move from the cathode to the anode. This flow of ions re-establishes the balance of electrons in the battery, allowing it to continue to produce electrical energy.
When the battery is recharged, the process is reversed, and the chemical reactions within the battery produce electrons at the positive electrode and remove electrons from the negative electrode, recharging the battery. This process can be repeated multiple times, allowing batteries to be used repeatedly.
