ABSTRACT
The inherent properties of graphene oxide (GO) and reduced graphene oxide (rGO) render these materials applicable in energy storage devices. The band gap energy of these materials is tunable. These materials possess high electrical conductivity, which can be elevated by surface modification. The specific surface area (SSA) can thus influence the conductivity of these materials. These tunable properties can be exploited for application in supercapacitor electrodes. This chapter presents an overview of the properties of GO and rGO in terms of optical, structural, bonding, and vibrational properties. The morphological properties and electrochemical properties of these materials for supercapacitor application have also been discussed.
