Screen printing of graphene-based ink shows promise for the integration of graphene within supercapacitor electrodes. A series of graphene/polyaniline inks are formulated, and screen printing is used to produce thin-film electrodes from these inks. In two-electrode measurements, the supercapacitors containing electrodes of NGP/PANI 1:1.5 show the best specific capacitance of 269 Fg−1 , power density of 454 kW kg −1 andenergy density of 9.3 Wh kg−1 , operating in 1M H2SO4 electrolytes.The supercapacitor shows excellent cycling stability with no degradation over 1000 charge/discharge cycles. Moreover, the performance of the NGP/PANI 1:1.5 fl exible supercapacitors are well-retained over 200 bending cycles. The key result of this work is the applicability of cheap and abundant raw materials. The combination of high NGP conductivity along with PANI reversible redox properties is regarded as necessary to achieve supercapacitors with long cycle-life.
