             abstract = "An electrical double-layer capacitor (EDLC) is based on the 
                         physical adsorption/desorption of electrolyte ions onto the 
                         surface of electrodes. Due to its high surface area and other 
                         properties, such as electrochemical stability and high electrical 
                         conductivity, carbon materials are the most widely used materials 
                         for EDLC electrodes. In this work, we study an activated carbon 
                         felt obtained from sheep wool felt (ACFf) as a supercapacitor 
                         electrode. The ACFf was characterized by elemental analysis, 
                         scanning electron microscopy (SEM), textural analysis, and X-ray 
                         photoelectron spectroscopy (XPS). The electrochemical behaviour of 
                         the ACFf was tested in a two-electrode Swagelok®-type, using 
                         acidic and basic aqueous electrolytes. At low current densities, 
                         the maximum specific capacitance determined from the 
                         charge-discharge curves were 163 F·g \−1 and 152 F·g 
                         \−1 , in acidic and basic electrolytes, respectively. The 
                         capacitance retention at higher current densities was better in 
                         acidic electrolyte while, for both electrolytes, the voltammogram 
                         of the sample presents a typical capacitive behaviour, being in 
                         accordance with the electrochemical results.",
