A hybrid nanostructure with partially reduced graphene oxide (rGO) and carbon nanofibers (CNFs) was fabricated and used as supercapacitor electrodes. A straightforward, environmentally friendly, and low-cost microwave-assisted reduction process was developed for the synthesis of rGO/CNF hybrid structures. The fabricated supercapacitor devices showed a specific capacitance of 95.3Fg(-1) and a superior long-term cycling stability. A capacitance retention of more than 97% after 11000 galvanostatic charge discharge cycles was obtained. These and other results reported in this paper indicate that high-rate, all-carbon, rGO/CNF hybrid nanostructures are highly promising supercapacitor electrode materials.

Flexible supercapacitor electrodes with vertically aligned carbon nanotubes grown on aluminum foils Dogru, Itir Bakis; Durukan, Mete Batuhan; Turel, Onur; Ünalan, Hüsnü Emrah (2016-06-01) In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor...
All SiC PWM rectifier-based off-board ultrafast charger for heavy electric vehicles Yildirim, Dogan; Ozturk, Serkan; ÇADIRCI, IŞIK; Ermiş, Muammer (2020-02-19) This study deals with the design, implementation and experimental performance of all silicon carbide pulse width modulation (SiC PWM) rectifier-based off-board ultrafast chargers (UFCs) for lithium titanate batteries of heavy electric vehicles. Different UFC configurations are proposed, depending upon the nominal battery voltage (400-1000 V DC) and charge capacity. Operating principles and control of UFC at unity and leading power factors are assessed and corresponding operating modes of PWM rectifier are d...
From carbon nanotubes to carbon nanorods Erkoç, Şakir (2000-09-01) The structural properties of single and multi-wall carbon nanotubes and the formation of carbon nanorods from multi-wall carbon nanotubes have been investigated by performing molecular-dynamics computer simulations. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that carbon nanorod formation takes place with smallest possible multi-wall nanotubes under heat treatment. On the other hand, it has been also found that single-wall carbon na...
Cobalt Oxide Nanoflakes on Single Walled Carbon Nanotube Thin Films for Supercapacitor Electrodes Durukan, Mete Batuhan; Ünalan, Hüsnü Emrah (2016-12-20) We demonstrate a simple and cost-effective approach for the fabrication of cobalt oxide (Co3O4) nanoflakes on single walled carbon nanotube (SWNT) thin films for supercapacitor electrodes. SWNT thin films are prepared by vacuum filtration and consecutive stamping method onto which cobalt hydroxide (Co(OH)(2)) nanoflakes are electrodeposited and annealed to obtain Co3O4. A gravimetric capacitance of 313.9 F.g(-1), corresponding to an areal specific capacitance of 70.5 mF.cm(-2) is obtained from the fabricate...
Initial Stages of Oxidation on Graphitic Surfaces: Photoemission Study and Density Functional Theory Calculations Barinov, Alexei; Malcıoğlu, Osman Barış; Fabris, Stefano; Sun, Tao; Gregoratti, Luca; Dalmiglio, Matteo; Kiskinova, Maya (2009-05-28) The initial oxidation stages of perfect and defective graphitic surfaces exposed to atomic oxygen have been studied with a combined high-resolution photoemission spectroscopy (HR-PES) and density functional theory (DFT) computational approach. The resulting oxygen-containing surface functional groups are identified by analyzing the multicornponent C 1s and O 1s core level spectra that are then interpreted on the basis of DFF calculations. In the initial oxidation stage, epoxy groups are formed on perfect gr...
