Electrocaloric Materials

by Tatiana Correia Qi Zhang

Since the 1997 Kyoto protocol of reduction of greenhouse gas emissions, the development of novel refrigerators has been a priority within the scientific community. Although magnetocaloric materials are promising candidates, they still need a large magnetic field to induce a giant ΔT as well as powerful and costly magnets. However, in electrocaloric materials (ECMs) a temperature change may be achieved by applying or removing an electric field. Since a giant electrocaloric effect on ferroelectric thin films was reported in Science in 2006, researchers have been inspired to explore such effect in different ferroelectric thin films. This book reviews electrocaloric effects observed in bulk materials as well as recent promising advances in thin films, with special emphasis on the ferroelectric, antiferroelectric and relaxor nature of ECMs. It reports a number of considerations about the future of ECMs as a means of achieving an efficient, ecologically sustainable and low cost refrigerator.

Electroceramics for High Performance Supercapicitors

by Inamuddin Tariq Altalhi Sayed Mohammed Adnan

ELECTROCERAMICS FOR HIGH PERFORMANCE SUPERCAPACITORS The book describes the state-of-the-art analyses of high-density supercapacitors. In the near future, high-energy density materials will be required to accommodate the increased demand for gadgets, hybrid cars, and massive electrical energy storage systems. Fuel cells, supercapacitors, and batteries have the highest energy densities, but traditional capacitors have gained attention for intermittent energy harvesting owing to their high energy transfer rate and quick charging/discharging capability. The large amount of electric breakdown strength and modest remnant polarization are keys to the high energy density in dielectric capacitors. Above 100??C or 212??F, polymer dielectric capacitors become unstable and begin to suffer a dielectric breakdown. Hence, dielectric ceramics are the sole viable option for high-temperature applications. This book provides a basic understanding of dielectric-based energy harvesting. After a detailed analysis of the state-of-the-art, it proceeds to explain the specific strategies to enhance energy storage features, including managing the local structure and phases assembly, raising the dielectric width, and enhancing microstructure and electrical uniformity. Also discussed is the need for novel materials with applications in high-density supercapacitors. Audience The book is designed for engineers, industrialists, physicists, scientists, and researchers who work on the applications of high-density supercapacitors.

Electrochemical Components

by Marie-Cécile Péra

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.
