What is the capacitance of a graphene-Pani composite?

The hybrid type film presents a gravimetric capacitance of 233 F g −1 and a volumetric capacitance of 135 F cm −3. Similarly, Wei et al. synthesized a graphene-PANI composite by a polymerization method, where graphene (∼15 wt %) was homogeneously coated on to PANI sheets .

Why are graphene composite electrodes used as SC electrodes?

Graphene composite electrodes with carbon and conductive polymers Conducting polymers have been widely explored as SC electrodes for their high pseudo capacitances arising from the reversible redox reactions at the electrode–electrolyte interfaces.

Can graphene be used as an electrode material?

Although individual graphene sheets are often partially agglomerated into particles of approximately 15–25 μm in diameter during the reduction process, the product with high specific surface areas of a few hundreds m 2 g −1 can be obtained, offering an electrode material of energy storage devices for the potential application (see Fig. 2).
