Abstract Conducting polymer-macroporous carbon composite electrode materials were prepared by deposition of a thin layer of polyaniline (PANI) on the surface of three-dimensionally ordered macroporous carbon. A specific capacitance of 1490 F/g was observed over the deposited PANI in the composite electrode. Good rate performance and cycle ability were realized on the composite electrode, attributed to the combined contribution from both the unique properties of the carbon matrix (e.g., highly ordered interconnected pores and good electrical conductivity) and pseudocapacitance of the deposited PANI layer. The three-dimensionally ordered pore structure of the carbon favored the diffusion of the electrolyte ions, hence not only improving the energy storage capacity but also enhancing power density.
