Batteries play numerous important roles in everyday life, from providing the initial power needed to start the engines of cars to acting as a backup source of electricity in telecommunications, public transportation and medical procedures.
What is a battery responsible for?
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
What happens when a battery stops working?
For primary batteries, like those in a flashlight, the reactions that fuel the battery will eventually stop happening, which means that the electrons that provide the battery with its charge will no longer create an electrical current. When this happens, the battery is discharged or “dead,” Sastry said.
