Abstract

Abstract: A promising electrode material for energy storage, poly(3, 4-ethylenedioxythiophene):poly(styrenesulfonate)@graphite-phase C3 N4 composite is reported, which is prepared by a simple direct mixing process. The contents of g-C3 N4 in the composite are investigated and optimized to give the best supercapacitor characteristics. The composite shows a good specific capacitance of 277 F g −1 at the current density of 1 A g −1 in 1 M H2 SO4 . More significantly, the composite exhibits the energy density of 10.2 Wh kg −1 at a power density of 4245 W kg −1 . After 5000 charge/discharge cycles, the capacitance retention rate still remains at 94.2%.
