Abstract: An extremely high-performance polyaniline electrode was prepared by potentiostatic deposition of aniline on hierarchically porous carbon monolith (HPCM), which was carbonized from mesophase pitch. A capacitance value of 2200 F g?1 of polyaniline was obtained at a power density of 0.47 kW kg?1 and an energy density of 300 Wh kg?1. This active material deposited on HPCM also has an advantageous high stability. These superior advantages can be attributed to the backbone role of HPCM. This method also has the advantages of not introducing any binder, thus contributing to the increase of ionic conductivity and power density. High specific capacitance, high power and energy density, high stability, and low cost of active material make it very promising for supercapacitors.
