Application of GO in Energy Conversion and Storage

Abstract

The increasing depletion of fossil fuel inspires the demand for renewable energy and energy-efficient devices. GO-based materials emerge in applications of energy storage and conversion with superior advantages. Especially, the composition of GO with specified materials not only retains the inherent characteristics of GO but also induces various characters for improving the performance in energy conversion and storage. Due to the large surface area and ample oxygen containing functional groups, GO can bind many active materials or catalysts for hydrogen storage and generation. Moreover, the functional groups enable GO to further couple with other species and thus form various porous or hierarchical architectures as electrodes, electrolyte or current collector in the lithium batteries and supercapacitors.
