Abstract:Polyaniline/activated carbon composite material(PANI/C) was synthesized in 1mol/L HCl solution using in-situ polymerization method with commercially available activated carbon as raw material.Cyclic voltammetry,electrochemical impedance spectroscopy,galvanostatic charge/discharge tests were used to investigate the capacitance performance of PANI/C and original activated carbon materials in 1mol/L H2SO4 aqueous solution.The results show that the new material possesses higher specific capacitance and performs much better than activated carbon under high current densities.PANI/C electrode has a specific capacitance of 448.7F/g under the current density of 3mA/cm2,increased by 60% than activated carbon electrode.
Keywords:electrochemical capacitor  polyaniline  activated carbon  specific capacitance
