Supercapacitors are the efficient energy storing devices with advanced properties like high power density, better cycle life, and high durability. But due to less energy density they cannot be used in commercial sector. In order to remove this barrier graphene based electrodes are used in supercapacitors which results in high stability but lacking in high value of specific capacitance. In series of research, it has been suggested that graphene along with conducting polymers and metal oxides can be used as electrode material for supercapacitors in order to provide both high value of specific capacitance and stability. So, this review paper summarizes the recent studies of incorporation of graphene with conducting polymers and metal oxides based supercapacitors as efficient energy storing device.
