3.3 Characterization of EDLC
The electrolyte layer of the supercapacitor cell, constructed of an
optimised ion-conducting polymer, contained the non-porous carbon active
material positioned between two symmetric electrodes. Low-frequency
impedance spectroscopy (IS) and cyclic voltammetry (CV), which were used
to determine the specific capacitance of the EDLC device, were used to
assess its performance.
