摘要
Composite electrodes for supercapacitors were prepared via electrochemical polymerization onto activated carbon. The capacitance properties were investigated using cyclic voltammetry (CV), AC impedance spectroscopy and charge-discharge tests. These electrodes show a specific capacitance of about 354 F g(-1). This indicates that the in situ electro-polymerization of pyrrole onto carbon could improve the performance of carbon electrodes for use in supercapacitors. (c) 2005 Elsevier B.V.
