Electrochemical energy storage system undergoes chemical process to store and produce electricity. Batteries are the most widely used electrochemical energy storage systems in industrial and household applications (28). They are classified into two types namely primary and secondary batteries.
Among the energy storage systems, the most common and most used is Battery system. An electrochemical battery is a device that stores and releases electrical energy through reversible electrochemical reactions. It is made up of one or more electrochemical cells, each comprising two electrodes (an anode and a cathode) separated by an electrolyte.
Energy storage systems today find applications in various fields such as solar and wind power plants, electric vehicles (EVs), and electronics. Among the energy storage systems, the most common and most used is Battery system.
The electrochemical storage of energy has now become a major societal and economic issue. Much progress is expected in this area in the coming years. Electrochemical energy storage systems are essential in the development of sustainable energy technologies.
Various classifications of electrochemical energy storage can be found in the literature. It is most often stated that electrochemical energy storage includes accumulators (batteries), capacitors, supercapacitors and fuel cells [25, 26, 27].
The principle of operation of electrochemical energy storage devices is based on the formation of a chemical reaction between the electrolyte and the electrodes contained in it. Then there is a shortage of electrons on one of the electrodes and an excess on the other. This allows chemical energy to be converted into electrical energy.
