  • An eco-efficient synthetic route was developed to establish carbon superstructures with enhanced exposed nitrogen-rich active facets.

  • The synergistic effect of the 3D interconnected superstructures and the high nitrogen-doping content endows the N-rich carbon superstructures (NCS-5) with not only increased potassium-ion storage capabilities but also superior rate and cycling performance.

  • The regulation of the nitrogen doping types and morphology of NCS-5 is also discussed in detail based on the experiment results and density functional theory calculations.
