Disclosed herein is the fabrication method of producing nanoporous carbon materials with pore sizes ranging from 2 nanometer to 20 nanometer which can be used as electrode materials for a supercapacitor and an electric double layer capacitors being a kind of supercapacitor. The invention also relates to electric double layer capacitors utilizing these carbon materials as electrodes. The carbon materials presented in the present invention possess regular pores with dimensions ranging in between 2 nm and 20 mm and exhibit high electrical conductivity. These carbon materials shows low equivalent series resistance (ESR) and thus exhibits high charge storage capacity at high charging/discharging current density. |
