| Abstract | A novel activated carbon material with a multi-level structure is prepared by KOH-activation of chestnut shells at 800 °C (CAC8). The specific surface area and pore volume of the activated carbon obtained are as high as 1568.0 m2 g−1 and 0.94 cm3 g−1. The electrochemical performance of the CAC8 is very promising; the specific capacitance is 207 F g−1 at a current density of 1 A g−1 in 1 M H2SO4 electrolyte. A CAC8/PANI composite, which was synthesized through an interfacial polymerization method, presents a good electrochemical performance, including an excellent specific capacitance of 597 F g−1 and 80% retention of capacitance after 1000 cycles at a current density of 1 A g−1 in 1 M H2SO4 electrolyte. The high electrochemical performance can be due to the use of the multi-level structured carbon, which improves the charge transfer performance of CAC8/PANI composite materials. |
