A Self-Supporting Electrode for Supercapacitors Prepared by One-Step Pyrolysis of Carbon Nanotube/Polyacrylonitrile Blends


  • This research was supported by the European Research Training Network NANOCOMP under the contract number HPRN-CT-2000-00037.


A new type of supercapacitor electrode is reported, prepared by pressing a carbon nanotube/polyacrylonitrile blend and then pyrolyzing the pellet (see Figure). Although their specific surface area is very low, e.g., 200 m2 g–1, the C/C composites demonstrate high values of capacitance, up to 100 F g–1. The authors propose two explanations for these remarkable values.
