Book Description
Sodium-ion batteries (SIBs) are gaining attention as alternatives to lithium-ion batteries (LIBs), particularly in the field of building-scale and grid-scale energy storage systems. The natural abundance and affordability of sodium relative to lithium makes the SIB a good contender for large-scale storage applications where battery cost is a more critical parameter than battery size and weight. At the cathode side of the battery, sodium layered-oxide materials are of great interest due to their similarities with the standard lithium layered oxide, and their high theoretical capacity of 240 mA h g −1. However, in practice, a high-energy sodium-ion cell is difficult to achieve, and their poor surface stability leads to rapid degradation in contact with both air and electrolyte. This dissertation begins with a comprehensive study to evaluate the various degradation routes of a sodium layered oxide. This evaluation is used to guide the future modification projects which aim to stabilize the material. A sodium phosphate coating applied post-calcination is found to greatly stabilize the cathode surface in both air and during cycling. The coating acts as a stable, artificial surface layer during cycling and protects the material from degradation on exposure to air due to moisture and CO2. An alternative approach to surface stabilization is examined with the molten-salt synthesis method. In the molten salt, the particles preferentially grow parallel to the sodium diffusion channels, forming a micron-scale plate-like morphology. The edge planes, where reactivity and degradation are most severe, are highly narrow. The small surface area of the edge planes helps minimize surface reactions and subsequent capacity loss. Furthermore, the molten-salt synthesis method has benefits over the industrial coprecipitation technique and may be a practical method for large-scale synthesis of layered-oxide materials. Finally, the primary source of capacity fade during cycling is addressed at the electrolyte. The standard carbonate electrolytes degrade into an unstable, organic surface layer on the cathode surface. The electrolyte also causes transition-metal dissolution and its migration and attack on the anode. Two new classes of electrolytes are found to form a stable surface layer with minimal degradation of the bulk layered oxide. Together, the methods presented herein provide practical solutions to stabilizing layered-oxide cathode materials that can be applied either alone or in combination

Book Description
High Temperature Solid Oxide Fuel Cells: Fundamentals, Design and Applications provides a comprehensive discussion of solid oxide fuel cells (SOFCs). SOFCs are the most efficient devices for the electrochemical conversion of chemical energy of hydrocarbon fuels into electricity, and have been gaining increasing attention for clean and efficient distributed power generation. The book explains the operating principle, cell component materials, cell and stack designs and fabrication processes, cell and stack performance, and applications of SOFCs. Individual chapters are written by internationally renowned authors in their respective fields, and the text is supplemented by a large number of references for further information. The book is primarily intended for use by researchers, engineers, and other technical people working in the field of SOFCs. Even though the technology is advancing at a very rapid pace, the information contained in most of the chapters is fundamental enough for the book to be useful even as a text for SOFC technology at the graduate level.

Book Description
This book covers both the fundamental and applied aspects of advanced Na-ion batteries (NIB) which have proven to be a potential challenger to Li-ion batteries. Both the chemistry and design of positive and negative electrode materials are examined. In NIB, the electrolyte is also a crucial part of the batteries and the recent research, showing a possible alternative to classical electrolytes – with the development of ionic liquid-based electrolytes – is also explored. Cycling performance in NIB is also strongly associated with the quality of the electrode-electrolyte interface, where electrolyte degradation takes place; thus, Na-ion Batteries details the recent achievements in furthering knowledge of this interface. Finally, as the ultimate goal is commercialization of this new electrical storage technology, the last chapters are dedicated to the industrial point of view, given by two startup companies, who developed two different NIB chemistries for complementary applications and markets.

Book Description
The electrochemical storage of energy has become essential in assisting the development of electrical transport and use of renewable energies. French researchers have played a key role in this domain but Asia is currently the market leader. Not wanting to see history repeat itself, France created the research network on electrochemical energy storage (RS2E) in 2011. This book discusses the launch of RS2E, its stakeholders, objectives, and integrated structure that assures a continuum between basic research, technological research and industries. Here, the authors will cover the technological advances as well as the challenges that must still be resolved in the field of electrochemical storage, taking into account sustainable development and the limited time available to us.
