Abstract

Energy-storage composite electrodes were prepared by mixing activated carbons (ACs) modified with nanosize titanium oxide (TiO₂) through ultrasonic vibration in ethanol solution for 30 min. We examined the cyclic voltammetry of the composite electrodes in an aqueous electrolyte, 1 M H₂SO₄. It was found that the specific capacitance of the composite electrodes measured in a range of 0-0.8 V was increased from 100 to 155 F/g compared electrodes comprised of ACs only. This was attributed to a reduction of polarization of the ACs modified by nanosized TiO₂.
