Produktbeschreibung

Provides a comprehensive understanding of a wide range of systems and topics in electrochemistry This book offers complete coverage of electrochemical theories as they pertain to the understanding of electrochemical systems. It describes the foundations of thermodynamics, chemical kinetics, and transport phenomena--including the electrical potential and charged species. It also shows how to apply electrochemical principles to systems analysis and mathematical modeling. Using these tools, the reader will be able to model mathematically any system of interest and realize quantitative descriptions of the processes involved. This brand new edition of Electrochemical Systems updates all chapters while adding content on lithium battery electrolyte characterization and polymer electrolytes. It also includes a new chapter on impedance spectroscopy. Presented in 4 sections, the book covers: Thermodynamics of Electrochemical Cells, Electrode Kinetics and Other Interfacial Phenomena, Transport Processes in Electrolytic Solutions, and Current Distribution and Mass Transfer in Electrochemical Systems. It also features three appendixes containing information on: Partial Molar Volumes, Vectors and Tensors, and Numerical Solution of Coupled, Ordinary Differential Equations. * Details fundamental knowledge with a thorough methodology * Thoroughly updated throughout with new material on topics including lithium battery electrolyte characterization, impedance analysis, and polymer electrolytes * Includes a discussion of equilibration of a charged polymer material and an electrolytic solution (the Donnan equilibrium) * A peerless classic on electrochemical engineering Electrochemical Systems, Fourth Edition is an excellent resource for students, scientists, and researchers involved in electrochemical engineering.
