Hydrogen‑Bonded Interfacial Super‑Assembly of Spherical Carbon Superstructures for High‑Performance Zinc Hybrid Capacitors

Caption

  • The spherical carbon superstructures (SCS-6) are synthesized by a hydrogen-bonded interfacial super-assembly, owning surface-opening pores, interconnected channels and rich heteroatom species.
  • Maximized accessibility of surface-active sites and opposite charge-carrier storage mechanism ensure high ion storage efficiency.
  • The assembled zinc-ion hybrid capacitor based on SCS-6 delivers ultrahigh energy density (166 Wh kg−1) and super-stable cycle lifespan (500,000 cycles).
