Chemical energy is stored in batteries through a process called electrochemical reactions. In this process, electrons are transferred between two electrodes, one made of metal and the other of carbon. The reactions occur in an electrolyte solution that contains ions.
Electrochemical batteries convert chemical energy directly into electrical energy and provide DC current. They consist of electrochemical cells that convert stored chemical energy into electrical energy. An electrochemical battery works by using a chemical reaction to produce an electric current.
Batteries convert chemical energy directly to electrical energy. In many cases, the electrical energy released is the difference in the cohesive [ 17 ] or bond energies of the metals, oxides, or molecules undergoing the electrochemical reaction.
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT’s Department of Materials Science and Engineering.
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
The electrolyte is a conductive material that allows electrons to flow between the two electrodes. When a battery is connected to a load (such as a light bulb), electrons flow from the anode to the cathode through the electrolyte. This creates a current that powers the load.

Batteries are classified into primary and secondary forms: • Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless.
