Abstract: Electronic Double-Layer Capacitors (EDLCs), with high capacitance and good charge and discharge property, have great prospect for use as a kind of new power device. In this paper, a new kind of nano-porous conducting carbon aerogel with controllable microstructure is used as electrodes for making EDLCs, and the specific capacitance of obtained EDLCs is 25F/g, the resistance is less than 1Ω, and the leak current less than 1mA.
