Manganese cobalt oxide nanoflakes for electrochemical energy storage

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.

Automated summary

This study successfully synthesized manganese cobalt oxide nanoflakes via a hydrothermal process, demonstrating high specific capacitance and cyclic stability, making it suitable for supercapacitor electrode materials.
