CATALYTIC COMPOSITION COMPRISING CATALYTIC ACTIVATED CARBON AND CARBON NANOTUBES, MANUFACTURING PROCESS, ELECTRODE AND SUPER CAPACITATOR COMPRISING THE CATALYTIC COMPOUND

摘要

The invention relates to a composition that comprises a polymer binder and a catalytic compound which comprises catalytic activated carbon and carbon nanotubes. The catalytic compound comprises carbon nanotubes obtained by chemical vapor deposition of a hydrocarbon heated from 400 to 1100ºC on activated carbon that has first been impregnated with a metal. The invention also relates to the use of the compound as electrodes, of particular use in electrochemical double-layered energy storage cells (supercapacitators). The invention is also aimed at the electrodes thus obtained and the supercapacitators containing these compound materials, as well as the process for preparing electrodes with a catalytic compound containing activated carbon and carbon nanotubes on a capacitator.
