Electrodeposited Nanoflakes of RuOx·nH2O on Three-dimensional Graphene for Flexible Supercapacitors

doi:10.15541/jim20180490

Abstract

Abstract:

Flexible electricity storage devices with high areal capacitance were urgently demanded due to recent development of advanced portable electronics. In this work, a facile cathodic electrodeposition method was employed to anchor RuO_x·nH₂O on three-dimensional graphene frameworks to realize improved utilization efficiency of RuO_x·nH₂O and shortened diffusion/transport path for electrons and protons, without adhesives. A high areal capacitance of 3.78 F?cm ^-2 was achieved at 2 mV?s ^-1, which was attributed to the feasible electrolyte transport into the nano layered-structure of RuO_x·nH₂O. Furthermore, all-solid-state flexible supercapacitors were prepared for practical application, achieving an energy density of 0.1 mWh?cm ^-2 and a power density of 2.4 mW?cm ^-2 at a current density of 10 mA?cm ^-2, which surpassed most state-of-the-art works.
