Manganese dioxide nanorods intercalated reduced graphene oxide nanocomposite toward high performance electrochemical supercapacitive electrode materials.

摘要: The development of manganese dioxide-based nanocomposites as materials for energy storage applications is advantageous because its polymorphism behavior and structural flexibility. In this study, dioxide (MnO2) nanorod-intercalated reduced graphene oxide (rGO) nanocomposite was obtained through a simple hydrothermal method their electrochemical supercapacitance studied in three electrode half-assembly cell. basic spectroscopic diffraction data including Raman spectroscopy, scanning electron microscopy, transmission microscopy were employed to characterize the resulting nanocomposite. Cyclic voltammetry galvanostatic charge-discharge measurements conducted evaluate rGO-MnO2 electrode. delivered significantly higher capacitance than P-MnO2 under similar measurement conditions. This enhanced supercapacitive performance attributed chemical interactions synergistic effect between rGO MnO2, which helpful enhancing electrical conductivity providing sufficient space electrode/electrolyte contact during reaction.
