What is Battery?
A battery is an electrochemical source for generating energy to power appliances like mobile phones, electric cars, electric toothbrushes, etc. Invented in the 1800s, batteries consist of two electrodes and an electrolyte. When a battery is connected to an external circuit, the circuit is complete and the electrolyte inside the battery undergoes a redox reaction. This redox reaction generates electricity that is used to power the functions of the external circuit.
