COMPOSITE CATALYTIQUE A BASE DE CHARBON ACTIF CATALYTIQUE ET NANOTUBES DE CARBONE, PROCEDE DE FABRICATION, ELECTRODE ET SUPERCONDENSATEUR COMPRENANT LE COMPOSITE CATALYTIQUE

摘要

The subject of the invention is a composition comprising a polymer binder and a catalytic composite based on catalytic activated charcoal and carbon nanotubes. The catalytic composite comprises carbon nanotubes obtained by chemical vapour deposition of a hydrocarbon at a temperature ranging from 400 to 1100° C. on activated charcoal preimpregnated with a metal. The subject of the invention is also the use of the composite as constituent material of electrodes intended especially for electrochemical double-layer energy storage cells (supercapacitors). The invention also relates to the electrodes obtained and to the supercapacitors containing these composite materials, and also to the method of preparing electrodes based on the catalytic composite containing activated charcoal and carbon nanotubes on a collector.
