Abstract:
Manganese cobalt oxide (MnCo2O4) nanoflakes are synthesized by a simple
hydrothermal process. As a supercapacitor electrode material, MnCo2O4 nanoflake exhibits a specific capacitance of 256 Fg-1 at 5 mV s -1 in symmetric twoelectrode configuration. The sample shows an outstanding cyclic stability of 85%
retention of specific capacitance after 10,000 charge–discharge cycles at 2 A g-1
.
The MnCo2O4 nanoflake-based supercapacitor material shows an energy density value of 25 Wh kg -1 at a power density of 1 kW kg -1
. The present work
establishes the suitability of manganese cobalt oxide nanoflakes for supercapacitor electrodes.
