Abstract
In recent years, materials based on carbon dioxide compounds and transition metal oxide nanocomposites with
desirable synergistic properties have attracted a great deal of attention as potential candidates for high efficiency
electrochemical supercapacitors. Our work presents the development of high-performance supercapacitor electrodes
using the 3D-flower-shaped NH4V4O10 microstructures combined with nitrogen-doped graphene quantum
dots and cellulose (NHV-NGC). A simple in-situ hydrothermal synthesis was used to synthesize the NHV-NGC.
Various methods are employed to characterize the physiochemical properties of the synthesized composite. In
addition, cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy
(EIS) were used to examine the electrochemical behavior of the materials as designed. According to the
GCD profiles, the optimized NHV-NGC electrode has a specific capacitance of 1852.9 Fg
