The goal of this thesis is to optimize the growth of carbon nanotubes (CNTs) on a conducting substrate for use as an electrode to improve energy density in a double-layer capacitor. The focus has been on several areas, such as substrate material, growth conditions, catalyst variations, and thin-film deposition techniques in order to achieve growth of a high density, vertically-aligned carbon nanotube array suitable for use as an electrode. This thesis describes the methodology of modifying a significant number of parameters in order to achieve all of the targeted electrode specifications, with the exception of nanotube density. The successful growth of a CNT array on an aluminum foil substrate marks an important milestone for realizing a future commercial product.

Der volle Inhalt der QuelleThis research was part of an ongoing program studying the concept of multi-material dielectrics (MMD) with dielectric constants much higher than homogenous materials. MMD described in this study have dielectric constants six orders of magnitude greater than the best single materials. This is achieved by mixing conductive particles with an insulating surface layer into a composite matrix phase composed of high surface area ceramic powder and aqueous electrolyte. Specifically examined in this study was micron-scale nickel powder treated in hydrogen peroxide (H2O2) loaded into high surface area alumina powder and aqueous boric acid solution. This new class of dielectric, composite electrolyte dielectrics (CED), is employed in an electrostatic capacitor configuration and demonstrated dielectric constant of order 10 [raised to the 10th power] at approximately 1 Volt. Additionally, it is demonstrated that treated nickel can be loaded in high volume fractions in the CED configuration. Prior studies of composite capacitors indicated a general limitation due to shorting. This results from the onset of percolation due to excess loading of conductive phases. Insulated particles described herein are successfully loaded up to 40% by volume, far above typical percolation thresholds. Simple models are presented to explain results.

Der volle Inhalt der QuelleLithium-Ion Capacitors (LiCs) are the new emerging technology of hybrid supercapacitors that combines the advantages of conventional supercapacitors and lithium-ion batteries. They provide intermediate energy and power densities due to their hybrid composition based on a positive electrode made of activated carbon similar to that of supercapacitors and a negative electrode made of pre-lithiated carbon similar to that of lithium-ion batteries. The aim of this thesis is to study the aging of commercial LiCs using two accelerated aging procedures: calendar aging and cycle aging. One of their main particularities concerns the nonlinear capacitance evolution with respect to their voltage (C(V) curve). The first accelerated aging test is related to the calendar life of LiCs that represents their behavior independently of their usage. The degradation of their parameters due to aging is mainly affected by the voltage and the temperature only. These tests were applied to several cells at three different voltage values and two temperatures. The evolution of their impedances were followed during the whole aging period in order to identify an electrical model that can accurately describe the progress of aging and that possesses electrochemically meaningful parameters. The best voltage value that ensures the extension of the lifetime of LiCs was identified using the results of these tests. In addition, aging mechanisms that extremely depend on the applied voltage value were identified. They highlight the particularity of the functioning of LiCs. These results were confirmed using post-mortem analyses. The second accelerated aging test is the cycle aging that assesses the impact of the current on the life cycle of LiCs. The choice of current profiles was based on the electrochemical operating principle of LiCs. The evolution of the impedances and the C(V) curves of LiCs were compared and analyzed. Aging mechanisms produced during cycle aging were also evaluated. They depend on the voltage range in which the LiC operates. The optimal voltage window that guarantees a long lifetime of LiCs was highlighted

Der volle Inhalt der QuelleWith the ever-increasing need for miniaturized electronics, components must be compatible with the 3D integration. Murata Integrated Passive Solutions (MIS) offers the Passive Integrated Connecting Substrate (PICS) technology, which integrates passive components on silicon. The objective of the present work is to fabricate high energy density micro-supercapacitors (MSCs) (~ 10 J.cm⁻³) to meet the energy storage needs. This study focused on four key points: (1) implementation of a thin film inorganic solid-state electrolyte for MSCs, LiPON, (2) interfaces and storage modes (surface or bulk) optimization, (3) development of ultrathin LiPON layers deposited by Atomic Layer Deposition (ALD), and (4) MSC specific surface area enhancement via nano structuring processes. The whole work is based on a systematic study, combining electrical and electrochemical results with advanced physical and chemical analysis. When integrated in a Metal – Insulator - Metal (MIM) configuration, the LiPON electrolyte exhibited an electronic double layer storage mode (like EDLCs), with good performance in terms of kinetics and stored energy. The latter was further improved by implementing an oxide layer, TiO₂, implying new storage modes. This material/performance relationship served as a basis for the development of ultra-thin MSCs. The feasibility of an electrically functional ALD LiPON deposition was demonstrated, and its integration into high aspect ratio 3D structures gave first encouraging results regarding the targeted performance

Der volle Inhalt der QuelleDen vanligaste formen av uppvärmning i Sverige är fjärrvärme. Sverige har minskat landets utsläpp av koldioxid kraftigt det senaste årtiondet och fjärrvärmen har bidragit stort till denna bedrift. Denna teknologi är ideal när det gäller att återvinna samt använda värme så effektivt som möjligt. Potentialen för den teknik i framtiden är därför stor. Många fjärrvärmesystem har idag värmelager i systemet för att öka dess effektivitet och pålitlighet. Dessa värmelager kan potentiellt utnyttjas ännu mer i framtiden genom att aggera som balanskraft för elnätet. Det finns dock ingen data tillgänglig gällande lagerkapaciteten som finns tillgänglig i fjärrvärmesystemen i dagsläget. Syftet med detta examensarbete är därför att kvantifiera och analysera den installerade lagerkapaciteten i Sveriges fjärrvärmesystem. Den insamlade datan kan sedan användas i studier för framtida applikationer för värmelager, så som att agera som balanskraft för elnätet. All insamlad informationen om värmelagernas kapacitet har även analyserats för att hitta samband mellan den relativa lagerkapaciteten för varje fjärrvärmesystem och dess storlek, energikällor, kundpriser samt driftkostnader. Slutsatser som har dragits från denna analys är att de flesta fjärrvämesystemen i Sverige har värmelager installerade, samt att värmelager är vanligare i större fjärrvärmesystem. De flesta värmelagren används till att balansera daliga variationer i värmelasten och värmelager sänker även driftkostnaderna för fjärrvärmesystemen.

Der volle Inhalt der QuelleEnergy saving in buildings has become a major international issue. Indeed, the building sector is one the most energy consuming sectors, for instance in France it consumes more than 43% of the total produced energy, and also it is one of the most polluter with around 23% of the green house gas emissions. As more and more households appear, the energy demand will increase and the above mentioned problems will be ten times more sever making them unmanageable in the upcoming years if no measure is taken. Thus, to face this situation, many strategies have been setup in order to achieve some energy saving in buildings. Among these strategies we find the energy prediction part which deals with hour by hour right energy; the research and elimination part of thermal bridges which its main objective is to reduce as much as possible the energy losses representing around 30% of the energy consumption; and the energy conservation part in wall buildings for future recycling. Our thesis focuses on the last two parts by proposing different methods of CND as well as appropriate survey treatments which allow to highlight structural failure in buildings. Transfer matrix estimation approaches have been used to predict the thermal behavior for a building that is being put under any kind of stress.The main contribution of this thesis concerns the developing of an in-situ storage capacity measuring technique. This is important since there are many softwares proposing the structural composition of a building for a given amount of energy. Nevertheless, there isn’t any method available for confirming or invalidating the results coming from artificial calculations. This thesis brings a solution to this situation by proposing a simple method, with no obstacles, easy to setup and with satisfactory results

Der volle Inhalt der QuelleAutoassociativa neurala nätverk har varit ett attraktivt område för forskare den senaste tiden. Deras potential att modellera några aspekter av det mänskliga minnet placerade dem i rampljuset för djupare forskning. I detta projekt studerar vi effekterna av att modifiera ett autoassociativ minnesnätverk. Vi utvärderar lagringskapaciteten för olika autoassociativa minnesmodeller baserat på Hopfield- nätverksmodellen och Hebbians inlärningsregel. Modifieringarna som studeras i detta projekt är implementering av Ojas princip på inlärningsregeln och skapnandet av ett glest nätverk istället för ett nätverk med en alla-till-alla anslutning. Vi fann att Ojas princip förbättrade nätverkets förmåga att återkalla nyligen inlärda mönster och förbättrade förmågan upprätthålla gamla minnen. Det glesa nätverket ledde till att den totala lagringskapaciteten minskade med hänsyn till mängden av antal borttagna anslutningar.

Der volle Inhalt der QuelleLithium ion capacitors are new and promising class of energy storage devices formed from a combination of lithium-ion battery electrode materials with those of supercapacitors. They exhibit better electrochemical properties in terms of energy and power densities than the above mentioned storage systems. In this work, lithium manganese oxide spinel (LiMn2O4; LMO) and lithium manganese phosphate (LiMnPO4; LMP) as well as their respective nickel-doped graphenised derivatives (G-LMNO and G-LMNP) were synthesized and each cathode material used to fabricate lithium ion capacitors in an electrochemical assembly that utilised activated carbon (AC) as the negative electrode and lithium sulphate electrolyte in a two-electrode system. The synthetic protocol for the preparation of the materials followed a simple solvothermal route with subsequent calcination at 500 - 800 ?C. The morphological, structural and electrochemical properties of the as prepared materials were thoroughly investigated through various characterisation techniques involving High resolution scanning electron microscopy (HRSEM), High resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), Small-angle X-ray scattering (SAXS), Electrochemical impedance spectroscopy (EIS), Cyclic voltammetry (CV) and Galvanostatic charge/discharge.

Der volle Inhalt der QuelleHydrogen has high energy density and it is regarded as the future energy carrier. Hydrogen can be stored as a gas in high-pressure cylinders, as a liquid in cryogenic tanks and as a solid in metal hydrides. The storage of hydrogen in gas and liquid form has many limitations. Light metal hydrides show high energy density and are a promising and more practical mode of hydrogen storage. In particular, titanium and its alloys are promising metal hydrides for hydrogen storage due to their high affinity to hydrogen. The aim of this study is to investigate the effect of thermal annealing on hydrogen storage capacity of Ti-Pd multilayer systems. Ti-Pd multilayer films were prepared on CP-Ti (commercial pure Ti) and Ti6Al4V substrates using an electron beam evaporator equipped with a thickness monitor. The sequential deposition of layers Pd(50nm)/Ti(25nm)/Pd(50nm) was done at a constant deposition rate of 0.6 Å/s. The first batch of samples were thermally annealed at 550 °C in vacuum for two hours, the second batch of samples were annealed at 550 oC under H2(15%)/Ar(85%) gas mixture for two hours and the third series of samples was annealed under pure H2 gas at 550 oC for one hour. SEM showed relatively homogeneous and smooth topography of surfaces in as-deposited samples, while a rough textured surface was observed in both samples annealed under vacuum and under H2/Ar gas mixture. The samples annealed under pure H2 gas did not show any sign of crystallites grow but instead a relatively smooth surface with sign of etching. XRD revealed structural transformation as evidenced by the presence of PdTi2 phase in samples annealed under vacuum; in samples annealed under the gas mixture Pd2Ti was noted in addition to TiH2 and TiO2. While the TiH2 phase is an indication of hydrogen absorption, the TiPd2 phase suggests intermixing of the deposited layers and the presence of TiO2 is evidence of oxidation. The samples annealed under pure H2 gas showed only TiH2 with no trace of structural transformation. RBS confirmed the intermixing of layers in the samples annealed under vacuum and H2(15%)/Ar(85%) gas mixture, while samples annealed under pure H2 gas did not show any intermixing of layers. ERDA revealed an average H content of ~ 3.5 at.% in CP-Ti and ~6.2 at.% in Ti6Al4V for samples annealed under H2(15%)/Ar(85%) gas mixture. We recorded an hydrogen content of ~19.5 at.% in CP-Ti annealed under pure H2 while ~25.5 at.% was found in Ti6Al4V annealed under the same conditions. When the thickness of the Pd catalyst layers was increased to 100 nm (i.e. Pd (100 nm)/Ti (25 nm)/Pd (100 nm)), only ~ 12.5 at.% and 11.2 at. % hydrogen content was recorded in samples prepared on CP-Ti and Ti6Al4V alloy respectively, both annealed under pure hydrogen for one hour as above.

Der volle Inhalt der QuelleThis report investigates the down-aisle buckling load capacity of steel storage rack uprights. The effects of discrete torsional restraints provided by the frame bracing in the cross-aisle direction is considered in this report. Since current theoretical methods used to predict the buckling capacity of rack uprights appear to be over-conservative and complex, this research may provide engineers an alternative method of design using detailed finite element analysis. In this study, the results from experimental testing of upright frames with K-bracing are compared to finite element predictions of displacements and maximum axial loads. The finite element analysis is then used to determine the buckling loads on braced and un-braced uprights of various lengths. The upright capacities can then be compared with standard design methods which generally do not accurately take into account the torsional resistance that the cross-aisle frame bracing provides to the upright. The information contained in this report would be beneficial to engineers or manufacturers who are involved in the design of rack uprights or other discretely braced complex light gauge steel members subject to axial loads.

Der volle Inhalt der QuelleIn the context of progress in the electrochemical energy storage systems in the transport field, especially in the aeronautics, the issues of performance, reliability, safety and robustness of these elements are essential for users. This thesis is focused on these issues for the more electric aircraft. The technologies studied correspond to the latest generation commercial elements of Lithium-ion batteries (NMC/ graphite + SiO, NCA/graphite, LFP/graphite, NMC/LTO), Lithium-Sulfur (Li-S), Supercapacitor and Lithium-ion capacitors. The first part of this manuscript is dedicated to the performance quantification of the different electrochemical energy storage elements in aeronautical environment [-20°C, 55°C] and usage. An efficient and accurate electro-thermal model is developed and validated. The second part is devoted to the calendar and power cycling ageings as well as to the presentation of abuse testing results. A State Of Health (SOH) estimation based on incremental capacity analysis method is proposed. Finally, the robustness of the storage elements during accelerated ageing tests with a specific profile for the aeronautical usage is evaluated. The ageing models and SOH estimation methods proposed in the previous sections are used here to evaluate the impact of temperature on the degradation rate and to estimate the SOH of the cells with this aeronautical profile

Der volle Inhalt der QuelleCerium oxides (CeOx, 3/2≤ x ≤ 2) based catalysts are employed in several reactions with high economic interest, such as the reaction in three-way-catalysts. It is well know that is possible to improve the ceria catalytic properties, by mixing with zirconium oxide and adding metallic particles over the material surface. Meanwhile, the deposition of Zr atoms over CeO2(111) is little explored although it has already been used for synthesis Ag nanoparticles of controlled size. One of the particularities of the Zr/CeO2(111) systems is to form islands of height between 1,5 and 3,0 Å on the surface of the ceria, which are suggested in the literature to be Zr-O and O-Zr-O layers. However, the nature and magnitudes of interactions between Zr and CeO2 surface are little know, as well as the CeO2 modifications induced by Zr and the mechanisms for Zr oxidation and ZrO2 formation over the surface. Aiming to understand the Zr-CeO2(111) interactions and the ZrO2 formation over the CeO2(111), this mastering project perform a theoretical study of n (1 ≤ n ≤ 4) Zr adatoms absorption over CeO2(111), and the ZrO2 formation over CeO2(111). The charge analysis indicated charge transfer from Zr adatons to the surface together with change in species oxidation state. The Zr oxidize to Zr4+ and interact with surface O2- , where four Ce4+ cations reduce to Ce3+. Energetic analysis pointed out that the process is very stabilizing, more than 10 eV per Zr adatom. With the increase of quantity n of Zr adatoms over the surface, it is observer 4 × n Ce4+ reductions and O2- migrations from inside surface to close the Zr4+, forming ZrO2 aggregates over the surface. The O migration occurs because of two reasons, the O2- interaction with Zr4+ in the agregate is more stabilizer than the interaction of O2- with Ce3+ inside the surface, and the O migration decrease the strain produced bue to the radius of Ce3+ being greater than the Ce4+ radius. In addition, was found a stability trend for Zr4+ to migrate to inside surface Ce sites, due of the more Zr-O coordinations and release of the strain induced by Ce3+.

Der volle Inhalt der QuelleAn increase in energy and power densities is needed to match the growing energy storage demands linked with the development of renewable energy production and portable electronics. Several energy storage technologies exist including lithium ion batteries, sodium ion batteries, fuel cells and electrochemical capacitors. These systems are complementary to each other. For example, electrochemical capacitors (ECs) can deliver high power densities whereas batteries are used for high energy densities applications. The first objective of this work is to investigate the electrochemical performances of a new family of 2-D material called MXene and propose new solutions to tackle the energy storage concern. To achieve this goal, several directions have been explored. The first part of the research focuses on MXene behavior as electrode material for electrochemical capacitors in aqueous electrolytes. The next part starts with sodium-ion batteries, and a new hybrid system of sodium ion capacitor is proposed. The last part is the study of MXene electrodes for supercapacitors is organic electrolytes. The energy storage mechanisms are thoroughly investigated. Different characterization techniques were used in this work, such as cyclic voltammetry, galvanostatic charge-discharge, electrochemical impedance spectroscopy, scanning electron microscopy and X-ray diffraction
