Electrochemical properties of TiO2/ACF composites for supercapacitor |
| 초록 |
In this study, TiO2/activated carbon fibers (ACF) composites are prepared without heat-treatment as supercapacitor electrode materials. ACF are treated with different concentration of titanium isopropoxide solutions. These treated ACFs are calcinated by ultrasound energy at room temperature. The morphology and crystallinity of prepared samples are estimated by scanning electron microscope (SEM) and x-ray diffraction (XRD), respectively. The electrochemical properties of TiO2/ACF composites based electrodes are estimated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The experimental results indicate that the TiO2/ACF composite electrode led to 95% improvement in the specific capacitance as compared to pristine ACF electrode. These results are attributed that TiO2 doped on ACF surface enhances the wettability of electrode and increases ion-transport rate within ACF pores. |
