A obtenção de pentóxido de vanádio mesoporoso, bem como a síntese, caracterização e estudo das propriedades de novos compostos híbridos, formado a partir do xerogel de pentóxido de vanádio e do pentóxido de vanádio mesoporoso, intercalados com espécies convidadas, foram os objetivos desta tese. O interesse nestes materiais, que apresentam uma considerável gama de modificações estruturais e químicas, é devido a possibilidade de arquitetar propriedades específicas e produzir novos materiais visando aplicações em óptica, catálise, dispositivos eletrônicos e sensores. Os compostos híbridos foram obtidos mediante a reação de intercalação utilizando espécies diretivas estruturais, como cloreto de cetilpiridínio, e materiais poliméricos, como óxido de polietileno e poli o-metoxianilina, introduzidos no interior do óxido em questão. O método de síntese é simples e relativamente rápido, uma vez que os materiais são obtidos em, no máximo, 10 dias, além de não ser necessário o monitoramento durante o período de preparação e secagem. Os resultados experimentais apontaram que houve uma expansão interplanar, bem como, as propriedades eletroquímicas dos compósitos apresentaram uma maior estabilidade de após vários ciclos quando comparados ao xerogel de pentóxido de vanádio, indicando uma reação de intercalação. Uma outra etapa deste trabalho foi à obtenção de óxido de vanádio mesoporoso. A formação de mesoporos foi confirmada pelas isotermas de adsorção/desorção. Em seguida, foi realizada a reação de intercalação com a introdução de óxido de polietileno e poli o-metoxianilina. A reação de intercalação utilizando esses polímeros na matriz mesoporosa proporcionou o aumento da mobilidade de íons lítio bem como um aumento na carga total, durante a reação redox, resultando num efeito sinérgico. Neste contexto, pode-se afirmar que, o método empregado mostrou-se extremamente atrativo devido a sua simplicidade de realização, além de possibilitar a obtenção de materiais com potencial aplicação como dispositivos eletroquímicos, baterias, e sensores químicos. / Synthesis, characterization of vanadium pentoxide mesoporous and studies of properties of hybrids compound based on vanadium oxide xerogel and vanadium pentoxide mesoporous, intercalated with guest species have been the main of this thesis. The interest in those materials, that present a considerable structural and chemical modification, is due to the possibility to tailor specific properties and produce new materials to application in optic, catalysis, electronic displays and sensors. The hybrid compounds were obtained from intercalation reaction utilizing templates agent such cetylpyridinium chloride and polymerics species such polyethylene oxide and poly o-methoxyaniline into the oxide. The synthesis is simple and relatively fast, and those materials are obtained, in a maximum, 10 days, even though it is not necessary the monitoring during the preparation and dry. The experimental results show an increase of interplanar, as well as, electrochemical properties of composites presented a better stability after several cycles as compared to vanadium pentoxide xerogel, indicating an intercalation reaction. Another stage of this work was to obtain the mesoporous vanadium pentoxide. The presence of porous was confirmed by adsorption isothermal method. Afterwards, it was realized the intercalation reaction with the polyethylene oxide and poly o-methoxyaniline into the matrix. The intercalation reaction using polymers into the porous matrix resulted an increase of Li+ ions mobility as well as an increase of total charge during the redox reaction resulting a synergic effect. In this context, it can be state that, the method used showed extremely attractive due to its simple synthesis, as well as it has the possibility of obtain materials with potential application such electrochemical displays, batteries and chemical sensors.

La miniaturisation des systèmes électroniques est aujourd’hui l’un des enjeux majeurs de la recherche et demande une importante évolution des sources d’énergie. Les micro-accumulateurs tout solide sont une réponse parfaitement adaptée à ce besoin. Leur capacité est toutefois actuellement limitée à 50-200 µAh.cm-2 du fait de la difficulté d’employer des couches de matériaux actifs d’épaisseur supérieure à 5 µm. L’une des pistes pour augmenter la capacité spécifique des micro-accumulateurs est de déposer les différents matériaux sur un substrat texturé. Les techniques de dépôt sous vide classiques ne permettent pas de déposer des films conformes sur de telles surfaces, principalement à cause d’effets d’ombrage. L’objectif de ce travail de thèse a donc été de développer de nouvelles voies de dépôt pour la réalisation de micro-accumulateurs tout-solide 3D. Deux voies de dépôt chimique ont été explorées : la synthèse sol-gel et l’électrodépôt sous conditions hydrothermales. La synthèse sol-gel n’a pas permis d’aboutir à la réalisation de films denses et conformes. Cependant, elle s’est avérée très intéressante pour synthétiser des poudres de LiCoO2 rhomboédrique présentant d’importantes surfaces spécifiques, sans étape de broyage, à des températures de synthèse modérées (600-700°C). Le dépôt électrolytique en conditions hydrothermales s’est quant à lui révélé très prometteur tant pour sa vitesse de dépôt importante, jusqu’à 300 nm.mn-1, que pour sa température de synthèse basse, à partir de 125°C, sans nécessiter de recuit. Les films synthétisés présentent d’excellentes performances électrochimiques en électrolyte liquide et une conformité sur des substrats texturés supérieure à 97 %. / The miniaturization of electronic systems is today a main topic of research and requires an important evolution of energy sources. All solid state micro-batteries are a perfectly adapted solution for this need. However, their specific capacity is limited to 50-200 µAh.cm-2 due to the difficulty to use films of active materials thickness over than 5 µm. One of the answers to enhance micro-batteries specific capacity is to deposit materials on textured substrate. Nevertheless, classical vacuum deposition techniques are not adapted to deposit conformal thin films on such surfaces because of shadow effects. The aim of this PhD-work was to develop new synthesis routes to realize 3D all solid state micro-batteries. Two chemical synthesis routes were studied: the sol-gel method and the electrodeposition under hydrothermal conditions. The sol-gel synthesis was not efficient to realize conformal and dense films. However, this technique was very effective to obtain rhombohedra LiCoO2 powders with high specific surface, without grinding step, at moderate temperature (600-700°C). The electrodeposition under hydrothermal conditions was very promising, both for its high deposition rate (up to 300 nm.mn-1) and its low synthesis temperature (from 125°C) without any annealing. The synthesized films exhibited excellent electrochemical performances in liquid electrolyte and a conformity higher than 97 % on textured substrates.

Ce travail porte sur la synthèse et la caractérisation de nouveaux matériaux d’électrodes positives pour batteries au lithium. Nos recherches se sont principalement orientées vers les matériaux de type phosphates de métaux de transition, et notamment vers la famille des tavorites de composition (Li,H)FePO4(OH), qui présente une structure tridimensionnelle comportant plusieurs types de tunnels propices à l’insertion d’ions lithium. La structure du matériau LiFePO4(OH) a ainsi été parfaitement résolue, de même que celle du matériau FePO4.H2O, qui est un nouveau phosphate de fer (III) découvert au cours de ces travaux. Ces deux matériaux, ainsi que ceux obtenus par traitement thermique de la phase FePO4.H2O, ont été caractérisés à l’aide de différentes techniques d’analyse physico-chimiques. Leur comportement électrochimique vis-à-vis de l’intercalation / désintercalation du lithium a été étudié, ainsi que les mécanismes redox et structuraux associés mis en jeu. / This work deals with the synthesis and characterization of new positive electrode materials for lithium batteries. Our researches were mainly focused on phosphates of transition metals, and especially on the tavorite-type materials of composition (H,Li)FePO4(OH). Their structure is characterized by a three-dimensional network with different types of tunnels, which can host inserted lithium ions. In this context, LiFePO4(OH) structure was perfectly solved, as well as that of FePO4.H2O, which is a new iron (III) phosphate discovered during this work. These two materials, together with those obtained by heat-treatment of FePO4.H2O, were characterized using different analytical techniques. Their electrochemical behavior toward intercalation / deintercalation of lithium was also studied, as well as the structural and redox processes involved.

Dans les piles primaires au lithium, l'anode de lithium peut être couplée principalement à quatre matériaux de cathode (MnO2, SO2, SOCl2 et des composés fluorés CFx). Les piles Li/CFx présentent de nombreux avantages tels qu’une densité d'énergie élevée (jusqu'à 2200 Wh.kg-1), un potentiel de décharge relativement élevé (environ 2,4 V vs Li+/Li) et une longue durée de vie (plus de 10 ans à la température ambiante). Au cours de ce travail, nous avons intensément étudié les propriétés électrochimiques des carbones fluorés nanostructurés. Pour plus de performances, des précurseurs nanocarbonés de dimensionnalité différentes, et des procédés de synthèse gaz-solide variés ont été employés. Ainsi, des structures fermées comme les nanofibres de carbone (1D, tubulaire), ouvertes comme les nanodisques / nanocônes (2D en majorité, discotiques) et intermédiaires avec les noirs de carbone graphitisés. Chaque mode de synthèse a été optimisé en fonction du précurseur de départ (son facteur de forme, sa dimensionnalité, son degré de graphitisation ...). Pour remédier aux limitations des carbones fluorés commerciaux, leur mécanisme de décharge a été finement étudié afin d'améliorer notre compréhension sur la défluoration électrochimique d'une cathode CFx, et de les comparer aux CFx synthétisés au laboratoire, le but principal étant de dépasser les performances actuelles et de synthétiser des matériaux inédits pour la pile primaire au lithium. Des extracapacités par rapport aux valeurs théoriques dans les batteries Li/CFx ont été obtenues avec de nanocarbones fluorés spécifiques et le phénomène électrochimique à l’origine de cette extracapacité a été clairement expliqué. / For primary lithium batteries, the lithium anode can be coupled mainly four cathode materials (MnO2, SO2, SOCl2 and fluorinated carbons CFx). Li/CFx batteries have many inherent advantages such as high energy density (up to 2200 Wh.kg-1), a moderately high discharge potential (about 2.4 V vs. Li+/Li) and a long life (over 10 years at room temperature). During this work, the electrochemical performances in primary lithium battery of nanostructured fluorinated carbons were investigated. To improve their performances, carbonaceous precursors with different dimensionalities, and various gas-solid fluorination methods were selected. Thus, a closed structure such as carbon nanofibres (1D, tubular), opened such as carbon nanodiscs/nanocones (2D in majority, discotic) and intermediate with graphitized carbon blacks have been chosen. Each synthesis route was optimized based on the starting material and their specificities, i.e. the shape factor, dimensionality, graphitization degree, stacking mode. To address to the limitations of commercial CFx materials, their discharge mechanism has been studied in order to improve the understanding about the electrochemical defluorination of a CFx cathode, and to compare it to original CFx synthesized in our laboratory, the main purpose is to exceed the current performances and to synthesize unrealized materials for primary lithium battery. Extracapacities in Li/CFx batteries were obtained with some specific fluorinated nanocarbon materials and their explanation was discussed.

Les recherches réalisées au cours de ce doctorat portent sur l’étude et l’optimisation de mélanges de polymères, utilisés en tant qu’électrolytes solides polymères (SPEs) dans les batteries lithium et lithium-ion. Les composants de la batterie doivent pouvoir être mis en forme par un procédé sans solvant (extrusion), afin de réduire les impacts du solvant sur les propriétés de la batterie et d’optimiser la production (diminution de la toxicité et du temps de production). Pour répondre à ces objectifs, une étude a d’abord été menée sur des mélanges de polymères, sélectionnés d’après leurs propriétés individuelles, en se concentrant notamment sur les interactions entre le sel de lithium et chaque polymère. Un classement des interactions a été développé et a permis de montrer que le principal facteur les favorisant est le nombre donneur des groupements fonctionnels polaires présents sur les chaînes polymères. Enfin, les effets de ces interactions sur les phénomènes de transport ionique dans les mélanges ont été investigués. Par la suite, l’étude s’est focalisée sur les couples de polymères ayant des propriétés prometteuses et complémentaires, tels que le poly(oxyde d’éthylène) (POE) ou le polycaprolactone (PCL), qui ont des conductivités ioniques élevées, et un copolymère butadiène-acrylonitrile hydrogéné (HNBR), qui possède des propriétés mécaniques intéressantes mais une conductivité ionique limitée. Il a été conclu que ces mélanges présentent des propriétés encourageantes, comparées aux SPEs composés d’un unique polymère, telles que des conductivités ioniques élevées sur une large plage de températures, ainsi que de meilleures propriétés de stabilités mécanique et thermique. La dernière partie de ces travaux s’est portée sur l’optimisation des propriétés de ces mélanges, par une méthode innovante de réticulation sélective d’une des phases. Pour conclure ce doctorat, l’objectif final a été de réaliser un prototype performant de batterie lithium tout solide, entièrement obtenu par extrusion, et dont l’électrolyte et le liant au sein des électrodes composites sont composés des électrolytes polymères optimisés. Les résultats prometteurs obtenus ont permis la soumission d’un brevet, en association avec le partenaire industriel (TotalEnergies). / The research carried out during this PhD is focused on the study and optimization of polymer blends, used as solid polymer electrolytes (SPEs) in lithium and lithium-ion batteries. All components of the battery must be shaped by a solvent-free process (extrusion), in order to limit impacts of the solvent on the battery properties and improve the production process (reduce toxicity and production time). To achieve these objectives, a study was first conducted on a set of polymer blends, selected on the basis of their individual properties, with particular emphasis on the interactions between the lithium salt and each polymer. A ranking of the lithium salt solvating ability of these polymers was developed and revealed that the main factor affecting these interactions is the donor number of polar functional groups on the polymer backbones. The effects of these interactions on the ionic transport phenomena in blend electrolytes have been examined. Subsequent work focused on polymer couples with the most promising and complementary properties, such as poly(ethylene oxide) (PEO) or polycaprolactone (PCL), which exhibit high ionic conductivities, and a hydrogenated nitrile butadiene rubber (HNBR) with interesting mechanical properties but a lower ionic conductivity. It was concluded that these blends show encouraging properties, compared to single-polymer SPEs, such as higher ionic conductivities over a wide temperature range, as well as improved mechanical and thermal stability properties. The final research project was the optimization of these blend electrolytes using an innovative method of selective cross-linking of one of the polymer phases. The main aim of this thesis was to develop an efficient prototype of an all-solid-state lithium battery, entirely obtained by extrusion, in which both the electrolyte and the binder of the composite electrodes are composed of optimized polymer electrolytes. The promising results obtained have led to the filing of a patent, in association with the industrial partner (TotalEnergies).

The electrification within the automotive industry goes faster than ever, which drives an increased demand for more knowledge about batteries. Vehicle manufacturers should be able to tell how long the batteries will last and have a service program for electrified vehicles, just as there is for traditional, fuel-driven ones. Scania is in the process of developing new service methods for their hybrids and fully electrified vehicles where this thesis has been a part of this development by investigating the possibilities of having a workshop test to measure the capacity of the propulsion batteries.  During the thesis, essential parameters for cycling the batteries and measure the capacity with high accuracy have been identified and investigated by conducting lab tests. In parallel to defining the properties of a successful capacity measurement, the implementation of such a measurement at a workshop has been studied alongside a brief discussion about scheduling strategies. Conducting a capacity measurement in a workshop environment introduce new challenges, and the critical question arises, how long can the capacity measurement take? It is identified that the state of charge window size, the temperature, and the relaxation time are essential parameters to control. From the experimental part of the thesis, it can be concluded that the start temperature should lay in the range of 15-25 °C with a relaxation time of 5-10 minutes providing a satisfying accuracy. A SOC window size of 20-80% seems to be the most optimal balance between time spent and accuracy in the measurement. Furthermore, it is identified that the workshop's equipment is heavily influencing the time it takes to conduct a test. It is concluded that it is necessary to be able to charge and discharge the batteries. / Elektrifieringen av fordons industrin går snabbare än någonsin, vilket driver en högre efterfrågan på mer kunskap om batterier. Fordons tillverkare ska kunna redogöra för hur länge batterierna kan användas och ha ett service program för elektrifierade fordon, likt det som redan finns för traditionella, bränsledrivna fordon. Scania håller på att utveckla nya service metoder för sina hybrider och elektriska fordon där detta examensarbete har varit en del av denna utveckling genom att undersöka möjligheterna kring en verkstadsmetod för att mäta kapaciteten hos framdrivnings batterier.  Under examensarbetet har väsentliga parametrar för cykling av batterier och mätning av kapacitet med hög noggrannhet identifierats och undersökts med laboratorietester. Parallellt med arbetet för att definiera egenskaperna hos en precis kapacitets mätning har implementationen av en sådan mätning i en verkstad studerats tillsammans med en kort diskussion om strategier för schemaläggning av dessa tester. Det introducerar nya utmaningar att utföra kapacitets mätningen i en verkstad och den viktiga frågan uppstår, hur lång tid tar en sådan kapacitets mätning? Det har identifieras att SOC fönster storleken, temperaturen och relaxeringstiden är essentiella parametrar att kontrollera. Slutsatserna är att temperaturen bör ligga i intervallet 15-25 °C med en relaxeringstid på 5-10 minuter ger en tillfredställande noggrannhet. Ett SOC fönster motsvarande 20-80% är förefaller vara den mest optimala i avvägningen mellan tidsåtgång och precision. Vidare kan den tillgängliga utrustningen på verkstaden pekas ut som en starkt påverkande faktor till tiden det tar att utföra ett sådant verkstadstest.

Dans un contexte de progression du stockage d’énergie sous forme électrochimique dans les transports, notamment dans l’aéronautique, les problématiques de performance, de fiabilité, de sureté de fonctionnement et de durée de vie du stockeur sont essentielles pour utilisateurs. Cette thèse se focalise ces voltes pour l’avion plus électrique. Les technologies étudiées correspondent à des éléments commerciaux de dernière génération de type Lithium-ion (NMC/graphite+SiO, NCA/graphite, LFP/graphite, NMC/LTO), Lithium-Soufre (Li-S), supercondensateur et hybride (LiC). Une première partie de ce manuscrit s’attache à la quantification des performances des différents éléments dans l’environnement aéronautique [-20°C, 55°C] et pour l’usage aéronautique. Un modèle comportemental de type électro-thermique est développé et validé. La seconde partie est consacrée à la quantification du vieillissement des différents éléments. Les résultats de vieillissement calendaire et en cyclage actif sont présentés ainsi que ceux des tests abusifs. Une méthode d’estimation de l’état de santé (SOH) des éléments basés sur l’analyse de la capacité incrémentale (ICA) est proposée. Enfin, l’évaluation de la robustesse des éléments de stockage lors de tests de vieillissement accéléré avec un profil spécifique à l’usage aéronautique est proposé. Les modèles de vieillissement et la méthode d'estimation de SOH proposés précédemment sont utilisés ici pour évaluer l'impact de la température sur la vitesse de dégradation et pour estimer le SOH des cellules vieillies à l’aide de ce profil aéronautique. / In 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.

Cette thèse a pour objectif d’étudier l’influence de la recharge rapide sur le vieillissement des batteries lithium, et son impact sur les performances des véhicules électriques dans le cadre d’une utilisation postale.

Ensuite un modèle de véhicules électriques est présenté, il intègre le modèle de batterie, tout en le faisant vieillir en utilisant l’estimateur de vieillissement. Enfin, les différentes stratégies de recharges possibles sont énumérées et comparées. Pour conclure sur leurs influences sur le vieillissement des batteries, et donc les performances de véhicules. / This thesis aims to study the influence of fast charging on the aging of lithium batteries, and its impact on the performances of electric vehicles as part of a postal use. The first part is devoted to the modeling of lithium batteries with an equivalent electric circuit model, whose parameters could be identified using linear characterization tests. The second part is dedicated to the study of aging, and results in an aging estimator using data collected from accelerated aging tests programs. Then the postal usage is studied, and a power profile representative of the actual load on the battery is provided. The latter was used to validate the model of the battery in the field of postal use. Then the postal use is studied, and a current profile representative of the real behavior of the battery is provided. This profile was used to validate the model of the battery in the postal use domain. Then a model of electric vehicles is presented, it integrates the battery model, which can simulates the aging state of the battery using the ageing estimator. Finally, the various possible strategies of recharge are listed and compared, which leads to conclusions about their influences on aging of batteries, and the vehicles performance.
