Here a new electrode concept is introduced based on the direct growth of vertically-aligned carbon nanotubes (VA-CNTs) on embroidered Cu current collectors. The direct growth of VA-CNTs was achieved by plasma-enhanced chemical vapor deposition (PECVD), and there was no application of any post-treatment or cleaning procedure. The electrochemical behavior of the as-grown VA-CNTs was analyzed by charge/discharge cycles at different specific currents and with electrochemical impedance spectroscopy (EIS) measurements. The results were compared with values found in the literature. The as-grown VA-CNTs exhibit higher specific capacities than graphite and pristine VA-CNTs found in the literature. This together with the possibilities that the Cu embroidered structures offer in terms of specific surface area, total surface area, and designs provide a breakthrough in new 3D electrode concept10 p.application/pdfengcc-by (c) Aguilo-Aguayo, Noemí et al., 2017http://creativecommons.org/licenses/by/3.0/esNanotubsPlasma (Gasos ionitzats)ElèctrodesNanotubesPlasma (Ionized gases)Electrodesinfo:eu-repo/semantics/article6794212020-02-27info:eu-repo/semantics/openAccess29232892
