Exceptional pseudocapacitive properties of hierarchical NiO ultrafine nanowires grown on mesoporous NiO nanosheets

Abstract

Hierarchical NiO ultrafine nanowires grown on mesoporous NiO nanosheets with Ni foam as a substrate synthesized by a facile and effective hydrothermal method showed exceptionally high specific capacitance (1349 F g−1 at a current density of 5 A g−1), good rate performance (∼58% retention of the initial capacitance from 3 A g−1 to 50 A g−1) and superior electrochemical cycling stability (∼87% retention after 2000 cycles). The remarkable electrochemical performance can make the unique hierarchical NiO nanosheets/nanowires to be a perspective electrode material for electrochemical energy storage applications.
