This paper proposes a new bidirectional DC/DC converter for supercapacitor applications. The proposed converter has a parallel structure in supercapacitor side (where voltage is low and current is high) and a series structure in the other side. This structure increases efficiency of the converter. For current sharing in the parallel side of the proposed converter, two different methods are reco...

In this paper a novel optimal control strategy for energy management of an off-grid hybrid Stirling engine/Supercapacitor power plant is presented based on preliminary results proposed in [1]. An implementation of the control strategy is performed on a real time target that drives a dedicated testbed with a DC machine reproducing the behaviour of the thermodynamic Stirling Engine. The DC machin...

The dataset presented here is related to the research article entitled "Highly Efficient Electro-optically Tunable Smart-supercapacitors Using an Oxygen-excess Nanograin Tungsten Oxide Thin Film" (Akbar et al., 2017) [9] where we have presented a nanograin WO3 film as a bifunctional electrode for smart supercapacitor devices. In this article we provide additional information concerning nanograi...

Flexible all-solid-state supercapacitors based on graphene fibers are demonstrated in this study. Surface-deposited oxide nanoparticles are used as pseudo-capacitor electrodes to achieve high capacitance. This supercapacitor electrode has an areal capacitance of 42 mF cm(-2), which is comparable to the capacitance for fiber-based supercapacitors reported to date. During the bending and cycling ...

A new technology, the supercapacitor, has emerged with the potential to enable major advances in energy storage. Supercapacitors are governed by the same fundamental equations as conventional capacitors, but utilize higher surface area electrodes and thinner dielectrics to achieve greater capacitances. This allows for energy densities greater than those of conventional capacitors and power dens...

composite electrodes of polyaniline/mno2-multi walled carbon nanotube (pani/mno2-mwcnt), mno2-mwcnt nanocomposites and mwcnt was produced by the in situ direct coating approach. the supercapacitor performance of the nanocomposites was studied by fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the electrochemical properties of electrodes were also investig...

Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO 3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO 3 grains by a silica shell in combination with Spark Plasma Sintering is a way to process bulk composites having supercapacitor features with low dielectr...

SUPERCAPACITOR ELECTRODES BASED ON GRAPHENE MATERIALS by Steven M. Selverston Graphene is a new type of carbon material with promising potential in energy-storage applications such as supercapacitor electrodes. This paper introduces engineering of graphene, as well as a related material called reduced graphene oxide, as materials for use in supercapacitors. The introduction explains the basic d...

An in-plane micro-supercapacitor (MSC) which has a unique interdigitated electrode structure with through-holes was developed by laser annealing and ablation of carbon/polyamide acid composite coating on polyimide film. The film consisting multi-layer graphene or activated carbon remarkably lowered the resistivity carbonization polyamide acid. conducted to make an through-hole structure. were e...
