How Does a Battery Work?

Batteries store DC power by means of a chemical reaction. There are three components to a battery, the Cathode, Anode, and electrolyte. Electrolytes are chemical elements that resist and electric charge. The cathode is the positive terminal (+) and the anode the negative terminal (-) of the battery. These are the terminals to which we connect the conductor. Between the cathode and anode, an electrolyte is used to concentrate the electric energy at the anode. This creates a potential difference (voltage). The anode is energized, and the electrons want to move to point of low energy (the cathode), in order to achieve equilibrium, this flow of electrons provides an electric current that can be used to do work.
