provide electricity thanks to the chemical reaction of its one or several cells. They have three components, which are an anode, cathode, and electrolyte. The anode is the negative side, while the cathode is the positive side. A chemical reaction will only occur if the anode and cathode are placed into a circuit. Electrons will then flow, producing electricity. If either the cathode or anode has reached its lifespan, the battery is dead. Batteries come in different configurations. The commonly used are alkaline batteries, which are for single use only and thus, disposable. However, some batteries are rechargeable.
