What Is The Definition Of Battery?

     Batteries are devices that convert and store energy. They convert chemical or physical energy into electricity by reaction. Batteries can be divided into chemical batteries and physical batteries according to the energy they convert. A chemical battery or chemical power source is a device that converts chemical energy into electrical energy. It consists of two electrochemically active electrodes of different components, positive and negative, and an electrolyte made up of a chemical substance capable of providing media conduction. When connected to an external carrier, by conversion, the chemical energy inside provides electricity. A physical battery is a device that converts physical energy into electrical energy.
