Enhanced supercapacitive performance of porous activated carbon derived from polyaniline prepared by electrochemical synthesis

Green and scalable synthesis of 3D porous carbons microstructures as electrode materials for high rate capability supercapacitors

“…The result from their work showed an impressive specific capacitance ( C SP ) of 331 F g −1 at a specific current of 0.2 A g −1 , however, only 49% of capacitance retention was observed at a high specific current of 40 A g −1 . Li et al 14 electrochemically synthesized polyaniline, which was carbonized at 700 °C and subsequently activated at 450 °C under mixed oxygen and nitrogen. The SSA of the activated carbon was 929 m 2 g −1 and the C SP calculated from the cyclic voltammetry (CV) measurement was 285 F g −1 at a scan rate of 2 mV s −1 in 6 M KOH electrolyte.…”
