Abstract

There were many claims of synergic effect of carbon nanotubes and graphene leading to enhanced capacitance of the resulting composite. Here we show that "spacing" of graphene sheets with carbon nanotubes does not yield to any synergic effect of dramatically improved capacitance but in contrary, the resulting capacitance is merely arithmetic average of weight specific capacitances of the individual components.
