Efficiency Development of Hybrid Supercapacitors Using Reduced Graphene Oxide(rGO)/ZnO and Reduced Graphene Copper(II) Oxide(CuO) for High-Power Batteries
MetadataShow full item record
The purpose of this project is to bring the good features of the composite materials between ZnO/rGO and CuO/rGO to create a supercapacitor for use as a high performance battery. Detection of characteristics of graphene oxide (GO) rGO ZnO/rGO and CuO/rGO were analyzed with a chemical analysis instruments such as X-ray diffractometer (XRD) scanning electron microscope (SEM), Infrared absorption spectrometer (FT-IR) and thermal decomposition analyzer (thermogravity analyzer: TGA) and specific surface area measuring instruments (Brunauer, Emmett and Teller: BET). The electricalchemistry properties of this composite materials have a specific capacitance equal to 460.26 ± 4.25 F / g. The energy density is 18.36 kWh/kg and the power value is 25.23 kW/kg. This composite materials are suitable for producing supercapacitors for use as batteries in the future.
