• The effect of the addition of surfactants to an aqueous electrolyte on discharge property of the capacitor was investigated. Dodecylbenzene sulphonate surfactant drastically improved the specific capacitance of electric double layer capacitor (EDLC) electrode. The addition of surfactants promoted the electrolyte to access the interior portion of micropores. EDLC effective area was increased and subsequently specific capacitance was also increased. However, the specific capacitance depended on chemical structure and concentration of the surfactants added. The adsorbed surfactants interfered with mobillity of ions. This is another factor for decreasing the specific capacitance.
