The project aims in developing graphene-based nanocomposites with enhanced electrochemical performance with high specific capacitance and cycle stability suitable for supercapacitors. Nanofillers like multi wall carbon nanotubes (MWCNTs), iron oxide nanowires (Fe₃O₄ or Fe₂O₃ NWs) and manganese dioxide nanoparticles (MnO2) were employed to play the part of pseudocapacitors and exploit the synergistic effect between the graphene network and the redox reactions. 

Stable dispersions of graphene, Graphene oxide (GO), and their mixtures were produced with the aid of the surfactant Sodium dodecylbenzene sulfonate (SDBS). These dispersions were used for the spinning of fibers and for the fabrication of planar films on copper and stainless steel (ss) with the method of electrodeposition (EPD). 

Main objective of the project is the synthesis of all-solid-state supercapacitors based on fibers and films and the comparison of their electrochemical properties. To explore the potential applications in energy storage, the electrochemical performance of the all-solid-state supercapacitors is analysed using cyclic voltammetry (CV), galvanostatic charge/discharge (CD) and impedancewith a two-electrode cell.
