Book Description
Graphite is currently used as negative electrode material in commercial lithium-ion batteries. Unfortunately, this material suffers from a relatively low specific capacity (372 mAh.g-1). Its substitution by a conversion material with a higher specific capacity as ZnFe2O4 (1001 mAh.g-1) would be interesting to increase the capacity of lithium-ion batteries.The use of nanomaterials can also limit the volumetric expansion of the electrode during cycling and enhance lithium ions kinetics.ZnFe2O4 nanopowders were synthesized in the Nanometric Structures Laboratory at the CEA (Atomic Energy and Alternative Energies Commission) by laser pyrolysis. This flexible synthesis method allowed the production of zinc iron oxides nanopowders with different morphologies, depending on the chosen experimental parameters (precursors, choice of gases and flow rates). Electrochemical performances were then evaluated vs. metallic lithium at the Energy Lab of Nanyang Technological University. Fundamental lithium storage mechanisms for ZnFe2O4 oxide were investigated by operando characterizations (XRD and 57Fe Mössbauer) and compared with those of a ZnO/Fe2O3 mixture. This study was realized in collaboration with the Charles Gerhardt Institute (University of Montpellier).This works highlighted the promising electrochemical performances of a specific morphology of ZnFe2O4 nanoparticles, consisting in a bimodal size population of particles, and allowed the deeper understanding of the lithiation and delithiation reactions.

Book Description
Smart ceramic coatings containing multifunctional components are now finding application in transportation and automotive industries, in electronics, and energy, sectors, in aerospace and defense, and in industrial goods and healthcare. Their wide application and stability in harsh environments are only possible due to the stability of the inorganic components that are used in ceramic coatings. Ceramic coatings are typically silicon nitride, chromia, hafnia, alumina, alumina-magnesia, silica, silicon carbide, titania, and zirconia-based compositions. The increased demand for these materials and their application in energy, transportation, and the automotive industry, are considered, to be the main drivers. Advanced Ceramic Coatings for Energy Applications covers recent developments in conducting electrodes, photovoltaics, solar cells, battery applications, fuel cells, electrocatalysts, photocatalysts and supercapacitors. The book is one of four volumes that together provide a comprehensive resource in the field of Advanced Ceramic Coatings, also including titles covering: fundamentals, manufacturing, and classification; biomedical applications; and emerging applications. The books will be extremely useful for academic and industrial researchers and practicing engineers who need to find reliable and up-to-date information about recent progresses and new developments in the field of advanced ceramic coatings. It will also be of value to early career scientists providing background knowledge to the field. Includes comprehensive coverage of advanced ceramic coatings for energy applications Features the latest progress and recent technological developments Includes comparisons to other coatings types (e.g., polymers, metals, and enamel) to demonstrate potential, limitations, and differences Contains extensive case studies and worked examples

Book Description
"This is the first machine-generated scientific book in chemistry published by Springer Nature. Serving as an innovative prototype defining the current status of the technology, it also provides an overview about the latest trends of lithium-ion batteries research. This book explores future ways of informing researchers and professionals. State-of-the-art computer algorithms were applied to: select relevant sources from Springer Nature publications, arrange these in a topical order, and provide succinct summaries of these articles. The result is a cross-corpora auto-summarization of current texts, organized by means of a similarity-based clustering routine in coherent chapters and sections. This book summarizes more than 150 research articles published from 2016 to 2018 and provides an informative and concise overview of recent research into anode and cathode materials as well as further aspects such as separators, polymer electrolytes, thermal behavior and modelling. With this prototype, Springer Nature has begun an innovative journey to explore the field of machine-generated content and to find answers to the manifold questions on this fascinating topic. Therefore it was intentionally decided not to manually polish or copy-edit any of the texts so as to highlight the current status and remaining boundaries of machine-generated content. Our goal is to initiate a broad discussion, together with the research community and domain experts, about the future opportunities, challenges and limitations of this technology."--Publisher's website.

Book Description
This thesis systematically introduces readers to a new metal-organic framework approach to fabricating nanostructured materials for electrochemical applications. Based on the metal-organic framework (MOF) approach, it also demonstrates the latest ideas on how to create optimal MOF and MOF-derived nanomaterials for electrochemical reactions under controlled conditions. The thesis offers a valuable resource for researchers who want to understand electrochemical reactions at nanoscale and optimize materials from rational design to achieve enhanced electrochemical performance. It also serves as a useful reference guide to fundamental research on advanced electrochemical energy storage materials and the synthesis of nanostructured materials.
