“…In supercapacitors, the charge storage is based on a reversible adsorption of electrolyte ions towards the surface of electrodes [ 3 , 4 , 5 , 6 , 7 , 8 ]. Therefore, the selection of the electrode materials is important due to a certain number of parameters such as: specific surface area, porosity, structure, electrical conductivity, surface wettability, and electrochemical stability to improve the performance of electrodes [ 2 , 9 , 10 , 11 , 12 ].…”
