Notes:
The increasing demand for energy worldwide has led to the development of supercapacitors, which are energy storage devices known for their high-power density, quick charging and discharging capabilities, large capacity, long lifespan, and environmental benefits. Here, we discuss the method for synthesizing manganese oxide/carbon composite materials through a one-step electrolysis process for potential application as supercapacitive electrode materials. The deposition of manganese oxide on graphite, together with the exfoliation of carbon flakes from the graphite electrodes induced by gas evolution during water electrolysis, led to the electrogeneration of a manganese oxide–carbon composite powder. After investigation of physical properties, the powder of manganese oxides/carbon composite was coated onto planar indium tin oxide (ITO) electrodes. Evaluation of the electrochemical performance and charge storage capacity revealed that ITO electrodes modified with the electrogenerated composite exhibited superior electrochemical performance compared with those modified only with a physical mixture of manganese oxide and carbon nanotubes.
