Porous Poly(5-Cyanoindole) Electrode with High Capacitance

Abstract:

A porous poly (5-cyanoindole) film was easily electrodeposited and for the first time evaluated as an active electrode material in 1.0 M H₂SO₄. The poly (5-cyanoindole) film was investigated using scanning electron microscope, cyclic voltammetry, impedance spectroscopy and charge-discharge test. The specific capacitance of poly (5-cyanoindole) electrode was 336 F g^-1 under the current density of 2.4 A g^-1 and decreased by 30% after 1000 cycles, which indicated that poly (5-cyanoindole) electrode had good cycle stability. Additionally, the specific energy of poly (5-cyanoindole) electrode reached 23 Wh kg^-1 when the specific power was 190 W kg^-1. These results indicated the feasibility of poly (5-cyanoindole) as electrode material for supercapacitors.
