In this work, symmetrical supercapacitors in the form of coin cell types were produced by using S-doped graphene powders.
In this study, excellent performance and wide operating voltage are obtained with an aqueous electrolyte. Aqueous electrolytes attracted more attention than other (such as organic solvents, ionic liquids) in supercapacitor applications because of their safety, low cost, nontoxicity. Polypyrrole (PPy), aniline 2-sulfonic acid (ASA) modified electrodes hydrothermal synthesized on carbon felt (CFt) for applications. We investigate the presence concentration ASA polymerization PPy. Furthermore,...
Abstract Herein, polythiophene-based supercapacitor electrode materials were successfully synthesized by the electropolymerization method. Thymol blue, bromothymol and bromophenol blue added to polythiophene polymerization medium as dopants, energy storage properties of thiophene-based material investigated. Polythiophene/bromothymol (PTh/BTB) gave an interesting zigzag morphology, which is unique in literature (specific surface area PTh/BTB PTh: 32.629 m 2 g −1 13.812 ). The performance...
In this work, nitrogen doped graphene oxide powder (N-GrOP) was used as an additive for fumed silica based gelled electrolyte of valve regulated lead acid (VRLA) batteries the first time in literature. Optimum amount determined 0.4 wt% N-GrOP by using electrochemical methods and corrosion tests. The structural features with without investigated SEM analysis.

Conducting polymer and carbon-based materials are important in supercapacitor applications as capacitive materials. However, the use of these alone limits their application due to poor rate capability short lifetime or low capacitance. Herein, electrodes were successfully synthesized by two step process on carbon-felt. Firstly, S-GO, N-GO Cl-GO was obtained chronoamperometry method at room temperature. After, PANI composites through a hydrothermal with S, N Cl heteroatom doped graphene oxide...
