High density energy storage is one of the current demands for sustaining renewable energy systems. This requires high charging and discharging rate, large power density and stability for prolong time of service. Several materials have been explored however none of them satisfy most or all of these requirements. Graphene oxide and Poly Vinyl Alcohol based nanocomposites have recently gained attention due to high mechanical stability. We have explored the use of Graphene Oxide – Poly Vinyl Alcohol nanocomposite as electrode material for supercapacitor applications. The oxygen containing groups in Graphene oxide enables the composite to store pseudo charge making it attractive for supercapacitor applications. Nanocomposite were synthesized by mixing poly vinyl alcohol and graphene oxide in solution phase. Electrochemical characterization shows that the Graphene Oxide – Poly Vinyl Alcohol has high specific capacitance and long life cycle, further they are ecofriendly, economical and hence potential candidates to be used as electrodes in supercapacitors.
