Cycling Performance of Supercapacitors Assembled with Polypyrrole/Multi-Walled Carbon Nanotube/Conductive Carbon Composite Electrodes

Year: 2011

Type: article

Abstract: Polypyrrole (PPy)/multi-walled carbon nanotube (MWCNT)/conductive carbon (CC) composites are synthesized by the chemical oxidative polymerization method.The morphology analysis of the composite materials indicates uniform coating of PPy over MWCNTs and conductive carbon.The electrochemical performances of PPy/MWCNT/CC composites with different compositions are evaluated in order to optimize the composition of the composite electrode.Galvanostatic chargedischarge measurements and electrochemical impedance spectroscopy studies prove the excellent cycling stability of the PPy/MWCNT/CC composite electrodes.
