The high pyridine/pyrrole nitrogen-doped and carbonyl-functionalized nanosheets on flexible electrospun porous carbon nanofibers film cathode integrates the advantages of large specific surface area, strong hydrophilicity and high Zn²⁺ adsorption activity.
The Zinc-ion hybrid capacitors exhibits a high capacitance retention of 99.2% over 200,000 cycles at 40 A g⁻¹.
A synergistic Zn²⁺ storage mechanism between carbonyl and pyridine/pyrrole nitrogen atoms is proposed.
