1. A method for the preparation of an electrode including a support made of an aluminium based material, vertically aligned carbon nanotubes and an electrically conductive polymer matrix, said method including the following successive steps:
a) synthesizing, on a support made of an aluminium based material, a carpet of vertically aligned carbon nanotubes according to the CVD (Chemical Vapour Deposition) technique at a temperature less than or equal to 650° C.;
b) electrochemically depositing said electrically conductive polymer matrix on said vertically aligned carbon nanotubes from an electrolytic solution including at least one precursor monomer of said electrically conductive polymer matrix, at least one ionic liquid and at least one protic or aprotic solvent;
wherein said at least one ionic liquid comprises an anion, wherein the anion is (CF3SO2)2N−; and
wherein during said b) the electrolytic solution contacts the vertically aligned carbon nanotubes and the support.
