Abstract: The effect of properties of porous carbon fibre on electrochemical performance of supercapacitor were studied.The materials were obtained by dipping the natural cocoon (with and without carbonization treatment) using 65% nitric acid solution,following by thermal treatment under the different temperature.The pore structure and surface chemical properties of modified electrode materials were characterized by nitrogen adsorption/desorption,FT-IR,SEM and TEM.The electrochemical performance of composites was examined by constant current charge-discharge,cyclic voltammetry and electrochemical impedance spectroscopy.The results showed that with the increase of temperature,the specific surface area and pore volume increased gradually,and the average pore size decreased.When the carbonization temperature was 600℃,the specific capacitance of carbon fiber can reach as high as 124.56F/g compared to 82.69F/g that of first carbonized sample,increasing by of 51%.
