How Is Cadmium Used in Rechargeable Batteries?
Traditional Batteries Traditional batteries have two sides, the anode and the cathode, which work together to hold an electrical charge. The battery is slowly used as the charge passes from one side to the other, and the flow of electrons is diverted to power the device using the battery, which is then returned to the battery itself. In primary batteries, which can only be used once, this process is irreversible, and after it is drained the battery is useless and must be recycled or thrown away. This occurs because there is an actual chemical change in the acid and components used to hold the battery’s charge, caused by the electrons changing places.
