In this only up-to-date overview numerous examples and problems (with solutions) illustrate the theoretical fundamentals for beginners, while guiding advanced electrochemists from process development to modern applications in chemical process engineering in practice. It describes both the basic processes needed for chemicals, such as chlorine, hydrogen, aluminum, zinc, copper, and others, as well as modern electrochemical processes. Topics include plating technology, organic and inorganic electrochemical production processes, electrolysis as well as batteries and fuel cells -- thus addressing those students and young professionals in research, development and production wishing to gain swift understanding and insight.
