The book addresses the scientific principles underlying electrochemistry. Starting with the basic concepts of electricity, the early chapters discuss the physics and chemistry of the materials from which electrochemical cells are constructed and the properties that make these materials appropriate as cell components. Much of the importance of electrochemistry lies in the conversion of electrical energy into chemical energy and vice versa; the thermodynamics of these processes is described, in the context of a wide range of applications of these interconversions. An electrode is a surface at which an ionic conductor meets an electronic conductor and the book describes a wide variety of such interfaces, including many non-traditional examples. The structure of the ionic/electronic junction is examined and the reactions that occur there are discussed from molecular, energetic and kinetic viewpoints. Polarizations are phenomena that inhibit the free passage of electricity across electrodes and much of electrochemical research is devoted to understanding these processes and to reducing (or sometimes enhancing) their effect. Electroanalytical chemistry and voltammetric methods are described, but not unduly emphasized, in this text. Where appropriate, the mathematical underpinnings of electrochemical science are described, but the more difficult aspects are presented via the web. Much tangential material is made accessible in a similar fashion, as are answers to the problems that copiously illustrate the material.

Keith B. Oldham is Emeritus Professor at Trent University in Canada. His research interests are drawn from the fields of electrochemistry, applied mathematics and environmental issues focusing on the electrochemical applications of mathematical and computational techniques. He has co-authored several books, contributed to numerous others, and has published over 200 articles.

Alan Bond is based in the School of Chemistry at Monash University and teaches undergraduate electrochemistry and redox chemistry His research focuses on applications of modern electroanalytical techniques to solve problems in inorganic, analytical and biological chemistry. He has authored over 500 papers, patents and books. Recipient of a Fulbright Fellowship (1972), the Rennie Medal (1975) of the Royal Australian Chemical Institute, the David Syme Prize (1977), the Analytical Chemistry Division Medal of the Royal Australian Chemical Institute (1989), the Stokes medal awarded by the Electrochemistry Division of the Royal Australian Chemical Institute (1992), the Liversidge Award (The Australian New Zealand Association for the Advancement of Science), the Federation of Asian Chemical Societies Foundation Lectureship (1993) and a range of other awards.
