Fig. 6: Printed graphene MSCs on paper.
a Photograph of printed interdigitated graphene electrodes on paper to fabricate MSCs. b, c Cyclic voltammetry (CV) profiles of the graphene MSC at different scan rates from 5 to 1000 mV s–1. d Areal capacitance (C) as a function of the scan rate. e Relative areal capacitance for 10,000 charge-discharge cycles. C1 indicates the initial areal capacitance. f Nyquist plots of the device with and without bending deformation. The inset in f shows a schematic of a bent device with a bending radius (r) of 6 mm. g CV profiles of the device with and without bending deformation at a scan rate of 50 mV s–1.
