electromechanical battery (EMB), however, may be a better way to go or, at the very least, be an important piece in the evolving energy storage infrastructure. Various energy storage devices are compared for peak power and specific energy. Batteries and fuels produce roughly the same range of peak power, about one
In thermodynamic terms, a brand-new main battery and a charged secondary battery are in an energetically greater condition, implying that the corresponding absolute value of free enthalpy (Gibb’s free energy) is higher [222, 223].
When the battery capacity is less than 70%, it needs to be replaced by a new one, which is half of the price of a NEV. In the case of the BYD Tang, for example, the quotation in a 4S store for battery replacement is more than 50,000 yuan, which reflects the cost is high.
“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.
In a secondary battery, energy is stored by using electric power to drive a chemical reaction. The resultant materials are “richer in energy” than the constituents of the discharged device .
The reversible nature of the electrochemical processes in secondary batteries involves the movement of ions between the positive and negative electrodes during both charging and discharging, enabling a sustainable and rechargeable power source for various devices and systems. How do batteries work?
The flow of electron through the external circuit creates an electric current, therefore discharging the battery. Primary batteries can only be discharged. Once their chemical reactions are depleted or reach a point where they cannot sustain the necessary voltage, the battery is considered "dead" and cannot be recharged.

Batteries, hydrogen fuel storage, and flow batteries are examples of electrochemical ESSs for renewable energy sources [6]. Mechanical energy storage systems include pumped hydroelectric energy storage systems (PHES), gravity energy storage systems (GES), compressed air energy storage systems (CAES), and flywheel energy storage systems [5].
Gasoline and oxygen mixtures have stored chemical potential energy until it is converted to mechanical energy in a car engine. Similarly, for batteries to work, electricity must be converted into a chemical potential form before it can be readily stored.
