A current conductor for an electrochemical power device that includes an array of carbon nanotubes (CNT) anchored in a carbon nanotube metal composite layer and a structure that may incorporate nanoscale particles or thin film onto the current conductor is described. Additionally, a process for creating the structure using electrochemical plating of the metal layer onto the CNT array followed by separation of the structure from the substrate is provided. Another process includes creating the structure using co-electrodeposition of the CNT and metal from an electroplating bath using surfactants, physical energy, and a magnetic and/or electric field to orient the CNT and enhance the CNT density in the composite.
