Abstract

Abstract : Mo:ZnO nanoflakes were synthesized by single-step hydrothermal route to achieve superior electrochemical performance. Abstract : A single-step hydrothermal route for synthesizing molybdenum doped zinc oxide nanoflakes was employed to accomplish superior electrochemical characteristics, such as a specific capacitance of 2296 F g −1 at current density of 1 A g −1 and negligible loss in specific capacitance of 0.01025 F g −1 after each charge–discharge cycle (up to 8000 cycles). An assembled asymmetric supercapacitor (Mo:ZnO@NF//AC@NF) also exhibited a maximum energy density and power density of 39.06 W h/kg and 7425 W kg −1, respectively. Furthermore, it demonstrated a specific capacitance of 123 F g −1 at 1 A g −1 and retained about 75.6% of its initial capacitance after 8000 cycles. These superior electrochemical characteristics indicate the potential of this supercapacitor for next-generation energy storage devices.
