Abstract :
    In recent years, graphene-based batteries, especially flexible batteries that are lightweight and perform well in energy storage, have been considered. In this study, we prepared flexible batteries by coating the paper surface with graphene oxide / nickel oxide-iron (II) nitrate nanocomposite and studied its electrochemical performance. The physical and chemical properties of the nanocatalyst were determined by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The fabricated electrode has good cyclic stability and electrochemical stability, and its capacity at a scan rate of 0.011v/s is equal to 458.8 F/g, which is much higher than the sample without graphene.
