نویسندگان

چکیده

Porous activated carbon materials derived from biomass could be the suitable for high-rate performance electrochemical supercapacitors as it exhibits high surface area due to well-defined pore structure. Here, we report novel porous Triphala seed stones by chemical activation with zinc chloride at different carbonization temperature (400-700 °C) under nitrogen gas atmosphere. The was characterized Fourier transform-infrared (FTIR) spectroscopy, Raman scattering and scanning electron microscopy (SEM). Nitrogen adsorption-desorption measurements used study properties (effective areas, volumes size distributions). were performed in an aqueous 1 M sulphuric acid (H2SO4) solution a three-electrode cell set up. stones-derived micro- mesopores exhibit specific ranges 878.7 1233.3 m2 g-1 total volume 0.439 0.626 cm3 g-1. capacitance obtained measurement experiment 208.7 F A These results indicate that prepared nanoporous material would have significant possibility supercapacitor electrode high-energy-storage applications.

Nitrogen modification of highly porous carbon for improved supercapacitor performance

Nitrogen is added to porous carbon, in both the bulk network as heteroatoms and coatedon the surface of the pores, to increase the capacitance of electrodes for supercapacitor applications. Surface modification increases the amount of nitrogen by four times when compared to unmodified carbon that only contains nitrogen in the bulk. Pyrolysis of themodified carbon at a lower temperature also ret...

Carbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor

We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...

High power density electrodes for Carbon supercapacitor applications

This paper presents results obtained with 4 cm2 Carbon/Carbon supercapacitors cells in organic electrolyte. In the first approach, a surface treatment for Al current collector foil via the sol–gel route has been used in order to decrease the Al/active material interface resistance. Performances obtained with this original process are: a low equivalent series resistance (ESR) of 0.5 Ω cm2 and a ...
