Tremendous efforts have been dedicated to developing high-performance energy storage devices based onthe micro- or nano-manipulation of novel carbon electrodes, as certain nanocarbons are perceived to haveadvantages such as high specific surface areas, superior electric conductivities, excellent mechanicalproperties and so on. In typical electrochemical electrodes, ions are intercalated/deintercalated into/fromthe bulk (for batteries) or adsorbed/desorbed on/from the surface (for electrochemical capacitors). Fastionic transport, significantly determined by ionic channels in active electrodes or supporting materials, is aprerequisite for the efficient energy storage with carbons. In this report, we summarize recent designstrategies for ionic channels in novel carbons and give comments on the promising features based on thosecarbons towards tailorable ionic channels.
