                         supercapacitor is the electrode material. Developing electrode 
                         materials with high specific electrical capacitance and low 
                         electrical resistance enables an increase in the energy 
                         accumulated in the device. In addition, it is expected that the 
                         electrode material presents a simple procedure for preparation 
                         having low production cost and being environmentally friendly. 
                         This work is based on the deposition of silver nanoparticles on 
                         activated carbon felt (Ag@ACF) as a supercapacitor electrode. The 
                         samples were characterized by field emission gun scanning electron 
                         microscopy, X-ray diffraction, X-ray photoelectron spectroscopy 
                         and textural analysis. Supercapacitor behavior was evaluated by 
                         galvanostatic charge-discharge curves, cyclic voltammetry and 
                         electrochemical impedance spectroscopy using a symmetrical 
                         two-electrode Swagelok type cell, and three different aqueous 
                         solution electrolytes: 2 M H2 SO4 , 6 M KOH and 1 M Na2 SO4 . 
                         Ag@ACF presented a high specific capacitance in KOH, about 170 F 
                         g-1, which makes it an interesting material for supercapacitor 
                         electrodes and it showed good specific electrical capacitance, low 
                         resistance and high cyclability.",
