The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power. Inside a battery are two terminals (the anode and the cathode) with an electrolyte between them. An electrolyte is a substance (usually a liquid) that contained ions.

Supercapacitors (SCs) are those elite classes of electrochemical energy storage (EES) systems, which have the ability to solve the future energy crisis and reduce the pollution [ 1–10 ].
