Graphite has been widely used in catalysis, combustion, and other energy-related technologies. Recent years see graphene, a mono-atomic layer carbon atoms derived from graphite, attracting great attention for its potential to improve performance in these applications due to its large surface area, high chemical stability, excellent electrical and mechanical properties, and potentially much lower manufacturing cost compared to nanostructures like carbon nanotubes. Here we will present the syntheses and characterization of graphene-metal oxide nanocomposites and their electrochemical performance in energy storage applications. The metal oxide nanoparticles were synthesized and simultaneously self-assembled with dispersed graphene into graphene-metal oxide nanocomposites. The nancomposites were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and other techniques. Conductivities were measured using impedance spectroscopy. Furthermore, when used as electrode materials in energy storage devices, the nanocomposites showed much-improved charge-discharge performance.
