Electrochemical storage and energy converters are categorized by several criteria. Depending on the operating temperature, they are categorized as low-temperature and high-temperature systems. With high-temperature systems, the electrode components or electrolyte are functional only above a certain temperature.
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

Batteries are valued as devices that store chemical energy and convert it into electrical energy. Unfortunately, the standard description of electrochemistry does not explain specifically where or how the energy is stored in a battery; explanations just in terms of electron transfer are easily shown to be at odds with experimental observations.
