Book excerpt: Ce travail se situe dans le cadre général de l'étude de l'insertion électrochimique de métaux alcalins dans des matériaux carbonés susceptibles d'applications comme anodes de générateurs secondaires. Une attention toute particulière est portée sur l'influence de la nature de l'électrolyte et du matériau carboné sur les performances électrochimiques (capacités réversible et irréversible, évolution en cyclage). L'insertion des ions sodium dans des électrolytes à base de solvants carbonates est décrite pour le graphite UF4 et les fibres P75. L'utilisation du carbonate d'éthylène (EC) entraîne la formation d'une couche de passivation sur l'électrode carbonée, imperméable aux molécules de solvant mais permettant la diffusion des ions sodium. Ce film passivant a été caractérisé par microscopie électronique à transmission (imagerie, diffraction électronique et spectrométrie par pertes d'énergie des électrons transmis). Alors que l'emploi du carbonate de propylène (PC) conduit à l'exfoliation des domaines graphités, les électrodes peuvent être cyclées soit en utilisant des mélanges EC-PC ou ChloroEC-PC soit après formation d'un film de passivation dans EC préalablement au cyclage dans PC. L'étude de l'insertion du sodium dans des fibres de carbone issues de précurseurs différents (brai mésophase ou polyacrylonitrile (PAN)) a permis de mettre en évidence deux mécanismes de fixation de l'alcalin. L'intercalation entre les feuillets de graphène est le mécanisme majoritaire pour les fibres ex-brai alors que l'insertion dans la porosité devient significative pour les fibres ex-PAN. Des produits contenant une quantité notable de sodium et cyclant réversiblement peuvent alors être synthétisés. Enfin, une étude préliminaire concerne l'insertion du sodium dans des graphites modifiés par broyage, soit chimiquement par suroxydation électrochimique. Le graphite naturel UF4, dans lequel l'insertion du sodium ne conduit qu'à des produits très pauvres, peut ainsi, après broyage, intercaler des quantités importantes de sodium (NaC11). Les moyens d'optimiser les performances électrochimiques des matériaux anodiques sont alors discutés.

Available in PDF, EPUB and Kindle. Book excerpt: This unique book concerning fuel cells and their applications fills the gap which currently exists between the theoretical aspects and the detailed practical data available. It describes a technology that dates from the early classical discoveries of the 1850s which predicted that direct energy conversion of chemical energy into electricity with fuel cells would be far more efficient at lower temperatures than with combustion processes. The importance of fuel cells for energy saving purposes is emphasised. Their applications are wide-ranging with use found in local stations and power plants, in industry for the highly efficient conversion of waste and biomass materials and in carbon dioxide reduction in all fossil-fuel-burning processes. Unique features highlighted include their importance in spacecrafts and their development for affordable implementation in electric cars. The most recent scientific publications and manufacturer's brochures have been screened in order to bring together the state- of-the-art technology of fuel cells. Readers at all levels including chemists, physicists, chemical engineers ry technologists and students will appreciate this comprehensive overvie ind the clarity of numerous graphs and tables highly valuable.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the methods of storage commonly used in hybrid systems. After an introductory chapter reviewing the basics of electrochemistry, Chapter 2 is given over to the storage of electricity in the form of hydrogen. Once hydrogen has been made, we have to be able to convert it back into electricity on demand. This can be done with another energy converter: a fuel cell, the subject of Chapter 3. Such a system is unable to deliver significant dynamics in terms of storage and release of electricity and needs to be supplemented with another solution: a detailed study of supercapacitors is provided in Chapter 4.While the storage systems touched upon in the previous three chapters (hydrogen batteries and supercapacitors) both exhibit advantageous characteristics, at present they are still relatively costly. Thus, the days of the electrochemical accumulator by no means appear to be numbered just yet. This will therefore be the topic of Chapter 5. Finally, on the basis of the elements laid down in the previous chapters, Chapter 6 will focus on electrical hybridization of these storage systems, with a view to enhancing the performance (in terms of energy, lifetime, cost, etc.) of the newly formed system. Aimed at an audience of researchers, industrialists, academics, teachers and students, many exercises, along with corrected solutions, are provided throughout the book. Contents 1. Basic Concepts of Electrochemistry used in Electrical Engineering. 2. Water Electrolyzers. 3. Fuel Cells. 4. Electrical Energy Storage by Supercapacitors. 5. Electrochemical Accumulators. 6. Hybrid Electrical System. About the Authors Marie-Cécile Péra is a Full Professor at the University of Franche-Comte in France and Deputy Director of the FEMTO-ST Institute (CNRS).
