Super capacitors for energy storage: Progress, applications and

The Hybrid Super Capacitor (HSC) has been classified as one of the Asymmetric Super Capacitor''s specialized classes (ASSC) [35]. HSC refers to the energy storage mechanism of a device that uses battery as the anode and a supercapacitive material as the cathode. With enhanced operating voltage windows (up to 2.0 V, 2.7 V and 4.0 V in case of the aqueous
