Opis

Fundamentals of Electrochemistry provides the basic outline of most topics of theoretical and applied electrochemistry for students not yet familiar with this field, as well as an outline of recent and advanced developments in electrochemistry for people who are already dealing with electrochemical problems.

The content of this edition is arranged so that all basic information is contained in the first part of the book, which is now rewritten and simplified in order to make it more accessible and used as a textbook for undergraduate students. More advanced topics, of interest for postgraduate levels, come in the subsequent parts.

This updated second edition focuses on experimental techniques, including a comprehensive chapter on physical methods for the investigation of electrode surfaces. New chapters deal with recent trends in electrochemistry, including nano- and micro-electrochemistry, solid-state electrochemistry, and electrocatalysis. In addition, the authors take into account the worldwide renewal of interest for the problem of fuel cells and include chapters on batteries, fuel cells, and double layer capacitors.

O autorze

VLADIMIR S. BAGOTSKY, PHD, is a retired professor from the Frumkin Institute of Electrochemistry at the Russian Academy of Sciences, Moscow. Previously, he headed a department at the Moscow Power Sources Institute, where he supervised the development of new batteries for most Russian ICBMs, sputniks, and spacecrafts. He has extensive experience with both theoretical and applied electrochemistry. He has authored 400 scientific papers and four monographs, including, in 1952 (together with Professor A. N. Frumkin et al.), the first monograph on electrochemical kinetics, titled Kinetics of Electrode Processes, and served on the editorial boards of Journal of Power Sources and Elektrokhimiya.
