Abstract: This paper looks at the research that is being carried out on use of Graphene as an electrode material for supercapacitors which may be the replacement for the lithium ion batters in future. It also discuss about the scope of graphene based supercapacitors in various fields. Science and technology have been advancing rapidly over the last few decades; storing the energy has always been a problem. The problem faced by conventional energy storage system is that a battery can potentially hold a lot of energy, but it can take a long time to charge and a capacitor, on the other hand, can be charged very quickly, but cant hold that much energy comparatively. The solution emerged was the supercapacitor that is able to provide both of these positive characteristics without compromise. Currently, research is being carried out on enhancing the capabilities supercapacitor and Graphene is proving itself to be the best electrode material for it. Graphene is a nanomaterial of 2D flat monolayer carbon (bonded in hexagonal lattice). Graphene is a parent of all carbon allotropes with versatile properties
