Carbon nanotubes (CNTs) have been used as the electrochemical double layer in capacitor (EDLC) electrodes. CNTs were synthesized using thermal chemical vapor deposition (CVD) at a growth temperature of 750 °C by flowing C2H2. The surface morphology of the synthesized CNTs could be controlled with or without Al film deposition between the stainless (SUS) sheet and Fe catalyst film. Electrochemical measurements were performed in a three-electrode arrangement. H2SO4 with different concentrations was used as the electrolyte solution. The relation between the specific capacitance and the surface morphology of the CNTs and the electrolyte concentration were investigated. The results showed that the electrode formed using vertically aligned CNTs with higher electrolyte concentration exhibited higher specific capacitance.
