<p>This monograph covers the rapidly developing field of electrochemical supercapacitors capable of exhibiting many Farads of capacitance per gram of active materials. The volume is aimed at a broad spectrum of scientists and technologists, including electrochemists, chemists, electrochemical and electrical engineers, and materials scientists. Hence the book is self-contained, starting with introductory chapters on the double-layer at interfaces, principles of electrode-process kinetics, and of electrostatics required in the treatment of double-layers and ion solvation, and elements of the theory of dielectrics. The main body of the material is concerned with procedures for characterizing the behavior and performance of electrochemical capacitors. Similarities and differences between electrochemical capacitors and batteries are treated in some detail, together with applications of both small and large capacitance units such as computer memory back-up and hybrid battery-capacitor systems for electric-vehicle drive-trains. A section is included on the practically important and scientifically interesting topic of self-discharge of capacitors and batteries, and the mechanisms that can be involved in that phenomenon. The work concludes with an up-to-date technology survey and a summary of recent and earlier patents in the field.</p>

This volume continues the development of the Modern Aspects series in the electrochemical field. The series is now 18 years old, and it is relevant to note the degree of evolution that electro chemistry has undergone during this time, for it affects the character of the articles chosen. The trend is towards development of inter disciplinary areas of electrochemical science, with full stress upon the many directions of applications of knowledge of electrode processes. The degree of import which should be attached to electro chemical science arises from the changes in technology which must be made during the next few decades. These clearly involve a massive electrification and the gradual elimination of the present fossil fuel economy, for both ecological and economic reasons. Research on the fundamental aspects of the field-slow in development to a standard-must be promulgated, but its justification is the modern provisionofa basis for the needed future electrochemical technology. One vast area of potential application of electrochemical concepts is omitted by the present attitude. It is, of course, the electro biological aspect, perhaps, finally, the largest area of all for fruitful applications. These concepts are reflected in the editors' choice of chapters. Quantum mechanical descriptions of surfaces must be bravely faced. Oscillatory aspects of electrochemical systems are often met in nature and demand attention at a fundamental level. Organic electrochemistry is in an ascending phase. With the electro biological v Preface vi article, we hope to stimulate a beginning of electrodic applications in this area.

Bockris, J O'M

The present collection of articles follows the arrangement used in previous volumes. Solutions are discussed first, surfaces and double layers second, electrode kinetics third, and then the applied subjects. The introduction of spectroscopic methods to electrochemistry is well exemplified by NMR studies of ionic solutions, as represented here in the detailed article by E. von Goldammer. Correspondingly, the spectroscopic approach can be applied to surfaces, and B. G. Baker has written an introduction to this topic for electrochemists from the point of view of gas phase measurements. One of the topics which begins to reach a degree of sophistica tion in electrode process chemistry is the adsorption of organic species on electrodes, and this topic is described in our volume by the well-known electrochemist M. W. Breiter. The work has much rele vance to the corresponding electrode kinetics and oxidation of organic materials. Much less sophisticated is the position in the electrochemistry of sulfide minerals, but it has seemed worthwhile to have the present record described by D. F. A. Koch; his chapter demonstrates the value of qualitative electrochemical studies in this field. The Hydrogen Economy is perhaps an example of straw fire in electrochemistry, for its great popularity beginning in 1973 reflects an interest which can hardly grow larger. However, much discussion of the Hydrogen Economy is concerned with its nonelectrochemical v vi Preface aspects and D. P. Gregory gives here the latest from the hydrogen front, with emphasis on the electrochemistry.

Modern Aspects of Electrochemistry

<p>The first chapter in the present volume takes up a well-known theme in modern context: the ideas concerning non-Stokesian mechanisms of ion transport. We are happy that one of the great pioneers of modern electrochemistry, T. Erdey-Gniz, in collaboration with S. Lengyel, has consented to write this article for us. Along with it is a solution-oriented article in spectroscopic vein, namely, that by A. Covington and K. E. Newman on the analysis of solution constituents by means of nuclear magnetic resonance studies. Progress in the electrochemistry of the double layer has perked up, and the advances have been triggered from critical experiments, one showing that fluoride ions are specifically adsorbed, and the other showing that the position of maximum disorder of the water molecules occurs at a charge opposite to that needed for interpreta­ tions of capacitance humps in terms of water molecules. M. A. Habib, who has contributed to the theory in this area, reviews the con­ sequences of these changes in information. The rise in the price of energy toward a situation in which sources other than the fossil fuels become economical implies much for the fuel cell and electrocatalysis. It has long been known that electrocatalysis in real situations was more than a consideration of exchange current densities, and a gap remains in the formulation of the theory of supports for such catalysts, although Boudart has stressed so much the vital nature of them. P. Stonehart and K. A. Kinoshita describe progress in this area.</p>
