Influence of carbon nanotubes on electrochemical performances of activated carbon-based electrodes for supercapacitors in aqueous electrolytes |
| 초록 |
This work presented the electrochemical performances of 4 cm2 supercapacitor cells assembled with 200 μm thick active material films composed with mixtures of activated carbons and carbon nanotubes in aqueous electrolytes. Galvanostatic and electrochemical spectroscopy impedance measurements had been carried out. Galvanostatic measurements showed that both internal resistance and specific capacitance decreased with increasing the active material content. With 20% of CNT, the internal resistance was 0.6 Ω cm2 and the specific capacitance was 100 Fg1 measured at 20 mA cm2. These performances remained stable during 10,000 cycles. The characterization of the frequency behavior was also performed by electrochemical impedance spectroscopy. |
