Supercapacitors are intermediate devices between conventional batteries and dielectric capacitors that can be used in various electric systems. [ 1] The pseudo-capacitors have drawn great attentions because of their intrinsic properties of fast and reversible surface redox reactions that enable high charge storage capacities greater than double-layer supercapacitors. Besides, a main attraction …
