In the electrode-slurry, AB and VGCF formed electron conduction paths and displayed high electronic conductivity.
In such a composite structure, nanowire arrays possess open spaces for shorter ion diffusion length, while ultrathin metal Co shell has high electronic conductivity for fast electron transfer.
Furthermore, the graphene with high electronic conductivity can provide good conductive passageways.
As is known, the excellent electrode should primarily meet the following key requirements: (1) a large number of electroactive sites, (2) high transport rates of both electrolyte ions and electrons, and (3) high electronic conductivity [4].
Such outstanding property is likely due to the special 1D-structure including uniform electrically conductive carbon network, which brings high electronic conductivity and rapid Na+ diffusion.
The proposed GnP/AC composite shows a more defect-rich morphology synchronized with high electronic conductivity which greatly enhances the electrocatalytic activity and electron transfer mobility (RCT of 2.19 Ω).
Moreover, the low activation energy of metal oxide supplied the favorable route for charge carrier conduction at high temperature, which leads to the high electronic conductivity [18].
The nanoparticles seemed to be strongly attached to graphene, which has a high electronic conductivity.
The graphite carbon possesses high electronic conductivity, and the disorder carbon does not.
The remarkable electrochemical performance is attributed to its 2D structure and high electronic conductivity.
As a core in the composite, the N-CNT can provide a high electronic conductivity and robust framework [20].
