| Summary: | The heart of this report will be on two main objectives. They are firstly, the establishment of growth process for transition metal oxide and graphene composites that have precise morphology and weight ratio and secondly evaluate the charge storage mechanism of the aforementioned electrodes.
This is done through four experimental steps. Firstly, hydrothermal process was employed to synthesize Fe3O4 nanoparticles with graphene oxide nanocomposites. Next, the product from the first step was used to make the thin film supercapacitor electrodes via spray deposition technique. After which, the different weight ratio composites are put under electrochemical characterization. Lastly, I would propose some future works and conclude my report. |
