Coupling of EDLC and the reversible redox reaction: oxygen functionalized porous carbon nanosheets for zinc-ion hybrid supercapacitors

Abstract

Oxygen functionalized carbon nanosheets are constructed for use as cathode for boosting the performance of zinc-ion hybrid supercapacitors <italic>via</italic> the synergistic effect of EDLC and pseudocapacitance from the reversible transformation of oxygen functional groups.
