Electrochemical deposition of polypyrrole for symmetric supercapacitors 

 -  Journal of Power Source, 158(2), p.1533-1537, 2006 .
<br/><br/> 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.
