In chemical energy storage, energy is absorbed and released when chemical compounds react. The most common application of chemical energy storage is in batteries, as a large amount of energy can be stored in a relatively small volume [13]. Batteries are referred to as electrochemical systems since the reaction in the battery is caused by ...
