For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.

How does a battery produce electricity?

“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).

How do batteries convert chemical energy to electrical energy?

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.

What is a battery used for?

Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers.
