Journal ArticleDOI
Polyaniline-deposited porous carbon electrode for supercapacitor
TL;DR: In this article, the performance of PANI-deposited carbon electrodes in 1 M H2SO4 was evaluated by constant current charge-discharge cycling within a potential range from 0 to 0.6 V.
Journal ArticleDOI
Electrochemical and capacitive properties of polyaniline-implanted porous carbon electrode for supercapacitors
Wei Chih Chen,Ten-Chin Wen +1 more
TL;DR: In this article, composite electrodes for supercapacitors were prepared by electropolymerization of polyaniline (PANI) on the surface of activated-porous carbons and the surface morphology and the chemical composition of composite electrodes were characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).
Journal ArticleDOI
Identification of inductive behavior for polyaniline via electrochemical impedance spectroscopy
TL;DR: In this article, the presence of benzoquinone/hydroquinone (BQ/HQ) formed during the electrochemical polymerization at the upper potential limits causes inductive behavior to PANI.
Journal ArticleDOI
Negative capacitance for polyaniline: an analysis via electrochemical impedance spectroscopy
TL;DR: In this paper, a redox mechanism involving the role of BQ to impart negative capacitance to PANI is given and supported by the results from X-ray photoelectron spectroscopy (XPS) and an equivalent circuit including an inductor element (L) is found to fit perfectly with data from EIS.
Journal ArticleDOI
A novel composite gel polymer electrolyte for rechargeable lithium batteries
TL;DR: In this article, the electrochemical properties of composite electrolyte films incorporating LiClO 4 -propylene carbonate (PC) were studied and it was shown that TPU-PAN based gel PE shows high ionic conductivity at room temperature.
