How Do Rechargeable Batteries Work Chemistry. 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.
When a device is connected to a battery a light bulb or an electric circuit chemical reactions occur on the electrodes that create a flow of electrical energy to the device. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode where they recombine with their electrons and electrically neutralize. When they move the other direction they convert this chemical potential energy to electricity in the circuit and discharge the battery.
