A supercapacitor is a promising energy storage device between a traditional physical capacitor and a battery. Based on the differences in energy storage models and structures, supercapacitors are generally divided into three categories: electrochemical double-layer capacitors (EDLCs), redox electrochemical capacitors
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 ]. Rapid depletion of crude oil, natural gas, and coal enforced the scientists to think about alternating renewable energy sources.
Alternatively, supercapacitors are designed specifically to deliver energy very quickly, making them perfect complements to batteries. While batteries can provide ~10x more energy over much longer periods of time than a supercapacitor can (meaning they have a higher specific energy), supercapacitors can deliver energy ~10x quicker

Abstract. Supercapacitors (SCs) technology starts with the study of Helmholtz, who, in 1853, revealed that electrical charges not only can be kept on a conductor surface but also on the electrode–electrolyte "double-layer" interface.
