Self-assembled flower-like ZnCo2O4 hierarchical superstructures for high capacity supercapacitors

Author affiliations

Abstract

Self-assembled ZnCo2O4 nanosheets were synthesised by a one-step hydrothermal method and their electrochemical supercapacitor properties were investigated in 2 M aqueous KOH solution. Interesting capacitive properties were observed with a superb cyclic stability obtained even at a current density of 20 A g−1. A specific capacitance value of 1691 F g−1 was obtained at a current density of 1 A g−1 with an energy density of ∼57.4 W h kg−1. The experimental findings provide useful insights into the design of supercapacitors for potential high performance energy storage applications in the future.
