The fascinating properties of graphene, like high theoretical surface area, better
electrical/thermal conductivity, excellent mechanical behavior, and chemical inertness, make
it a suitable material for energy storage applications, specifically for supercapacitor. The
pristine graphene-based materials store charge forming a double layer at the
electrode/electrolyte interface and show many fold higher power density, but lag behind the
traditional batteries in terms of energy density, thereby limiting their broad application …
