<p>"... one of the best aspects of this book is in the excellent technical details describing other devices (conventional capacitors and batteries) to illustrate the differences between these energy-storage devices. Also, the condensed but very informative descriptions of some of the equipment used to characterize ES materials (SEM, TEM, x-ray analysis) are very enlightening for those who do not typically use these devices. There are excellent descriptions of the theory and application of these imaging and analytical instrumentations. The book provides a wonderful illustration of electrochemical supercapacitors for understanding the practical aspects of the technology. It also provides sufficient technical details on new materials for possible future use in ES components. Readers will gain a comprehensive understanding of the components, designs, and characterizations of ES. Those in industry and academia will benefit from this book."<br />—John J. Shea, from <em>IEEE Electrical Insulation Magazine</em>, July/August — Vol. 31, No. 4</p><p>"This book offers an essential background to researchers involved in the development of supercapacitors and may represent both a reference and a starting point for academic and industrial scientists. Also students and post-graduate fellows will find it a comprehensive and valuable resource." <br />—Catia Arbizzani, University of Bologna</p>
