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.",
