Preparation and electrochemical performance of hollow activated carbon fiber self-supported electrode for supercapacitor Ghent University
Supercapacitor with improved performance based on ALD-developed two-dimensional WO3/TiO2 heterojunction Ghent University
Ionic liquid-heteropolyacid: Synthesis, characterization, and supercapacitor study of films deposited by electrophoresis KU Leuven
Hybrid materials based heteropolyacids, silicotungstic acid (H4SiW12O40 center dot nH(2)O) or phosphomolybdic acid (H3PMo12O40 center dot nH(2)O), and a room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM] [BF4]) were synthesized. Carbon analysis showed that 1 mol of [SiW12O40](4-) reacts with 4 mol of [BMIM](+) and 1 mol of [PMo12O40](3-) reacts with 3 mol of [BMIM](+). Fourier transform infrared spectra showed ...
Characterization of supercapacitors matrix Vrije Universiteit Brussel
This paper treats supercapacitors matrix characterization. In order to cut off transient power peaks and to compensate for the intrinsic limitations in embedded sources, the use of supercapacitors as a storage system is quite suitable, because of their appropriate electrical characteristics (huge capacitance, small series resistance, high specific energy, high specific power), direct storage (energy ready for use), and easy control by power ...
Supercapacitors On-Board Light Rail Vehicles: Enhanced Energy Storage Systems for Improved Vehicle Efficiency. Vrije Universiteit Brussel
Electric powered vehicles are in use in many cities for the benefit of public transportation. Although they allow for significant reductions in terms of emissions, their efficiency can be markedly improved. Modern vehicles can feed back to the grid up to 40 % of the energy supplied to them. This energy can be sent to other vehicles on the line provided that they will consume it simultaneously; but this is infrequent for tram networks where the ...
TiO2 nanoparticles-functionalized two-dimensional WO3 for high-performance supercapacitors developed by facile two-step ALD process Ghent University
TiO2 nanoparticles-functionalized two-dimensional (2D) WO3 (TiO2NP-WO3) films fabricated by the facile two-step atomic layer deposition (ALD) process with following post-annealing at 380 degrees C were investigated as electrode material for supercapacitors. The surface functionalization of 2D WO3 electrode by TiO2 nanoparticles significantly enhanced the specific capacitance by similar to 1.5 times over the pure 2D WO3 electrode. Transition of ...
