▎ 摘　　要

We successfully demonstrate reduced graphene oxides supercapacitors processed by atmospheric pressure plasma jets. The optimized processing time is merely 15 s. The best specific capacitance achieved is similar to 274 F g(-1) as evaluated by cyclic voltammetry under a potential scan rate of 2 mV s(-1). The specific capacitance decreases from similar to 203 F g(-1) at cycle 1 to similar to 168 F g(-1) at cycle 2000 in a cycling stability test evaluated under a potential scan rate of 200 mV s (-1).
