Direct growth of vertically aligned single-walled CNTs on conducting substrate and its electrochemical performance in ionic liquids

We report fabrication of vertically-aligned single-walled carbon nanotube (VA-SWCNT) electrodes for a symmetric electrochemical capacitor using a simple ethanol-based CNT growth system. From the CNT direct growth technique, the electrode was easily prepared, and consequently assembled with ionic liq...
