Abstract
In this paper, a flexible film electrode was prepared by depositing graphene nanosheets on carbon nanotube paper as a self-standing electrode for high-performance electrochemical capacitors. The composite film has a layered structure, where carbon nanotubes were efficiently intercalated in the layer of graphene nanosheets. The hierarchical structure of graphene nanosheet/carbon nanotube paper electrodes shows lower resistance to ions and electron transport. The unique electrodes exhibit high-rate capability and long-term cycling ability. A quasi-rectangular shape of CV curve can still be maintained even at a high scan rate of 10 V s-1. The capacitance decay was only 6.9% after 10,000 cycles at a current density of 6.4 mA cm-2.
