Book excerpt: Quantitative methods for the analysis and design of electrochemical systems have progressed greatly over the past forty years. Much of this progress is due to the work of Professor John Newman of the University of California-Berkeley. A tutorial symposium was organized to recognize Prof. Newman¿s contributions on the occasion of his 70th birthday. This issue contains a series of invited lectures covering the basic principles of electrochemical engineering as well as a variety of examples of applications in electrodeposition, fuel cells, batteries, and electrolytic processes.

This book was released on 1976 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mathematical model which describes the operation of porous battery electrodes has been developed. It includes short time transient behavior of electrolyte concentration, porosity, current distribution, reaction rate, and detailed solution diffusion descriptions of sparingly soluble reactant. Calculations were made for constant current (50 mA/sq cm and 25 mA/sq cm) charging and discharging of Ag/AgCl electrodes. Results of calculations indicate that the concentration of the electrolyte, KCl, inside the porous electrode plays an important role in the performance of the electrode. During charging, the electrolyte concentration falls in the depth of the electrode, thereby decreasing the solution electrical conductivity. Reaction penetration depth on charging is very shallow, less than 0.3 mm, for the current densities investigated. On discharging, the electrolyte concentration in the depth of the electrode increases. Consequently, the electrical conductivity of the solution as well as the solubility of AgCl increases. A high reaction rate in the depth of the electrode is possible even at high current discharge. Charge utilization over 90% is predicted if the charge is stored uniformly by employing a slow charging rate.

Available in PDF, EPUB and Kindle. Book excerpt: A single pore Ag/AgCl electrode was constructed for the study of elementary processes that occur in porous electrodes. X-ray element scan was applied to determine the average local transfer current densities inside the pore. The morphology of AgCl on the surface of silver was studied using a scanning electron microscope. It was found that the size of AgCl particles depended on the average local current densities and the local electrolyte concentrations. Higher current densities gave smaller AgCl mounds, in general. The formation of AgCl was also observed to form mainly from electrolyte diffusion paths as opposed to solid phase diffusion. A porous structure of silver was observed after cycling. The use of intercalation compounds of graphite as reactants in nonaqueous secondary batteries has been investigated. Experiments were carried out on a cell of the type Li/LiClO4, DMSU/C, LiF. Two discharge plateaus were observed, one occurring above 4.0 V and another more predominant one between 2.8 and 2.5 V. The lower discharge plateau is characteristic of the discharge plateau of a primary battery using fluorographite as the reactant. The higher discharge plateau is probably dire to the formation of the intercalation compound CnClO4 (n>1). The lower discharge plateau is comparable to the behavior of the cells described by Watanabe, et al., (1970) and Brauer (1970) using flourographite as the reactant. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A Comprehensive Reference for Electrochemical Engineering Theory and Application From chemical and electronics manufacturing, to hybrid vehicles, energy storage, and beyond, electrochemical engineering touches many industries—any many lives—every day. As energy conservation becomes of central importance, so too does the science that helps us reduce consumption, reduce waste, and lessen our impact on the planet. Electrochemical Engineering provides a reference for scientists and engineers working with electrochemical processes, and a rigorous, thorough text for graduate students and upper-division undergraduates. Merging theoretical concepts with widespread application, this book is designed to provide critical knowledge in a real-world context. Beginning with the fundamental principles underpinning the field, the discussion moves into industrial and manufacturing processes that blend central ideas to provide an advanced understanding while explaining observable results. Fully-worked illustrations simplify complex processes, and end-of chapter questions help reinforce essential knowledge. With in-depth coverage of both the practical and theoretical, this book is both a thorough introduction to and a useful reference for the field. Rigorous in depth, yet grounded in relevance, Electrochemical Engineering: Introduces basic principles from the standpoint of practical application Explores the kinetics of electrochemical reactions with discussion on thermodynamics, reaction fundamentals, and transport Covers battery and fuel cell characteristics, mechanisms, and system design Delves into the design and mechanics of hybrid and electric vehicles, including regenerative braking, start-stop hybrids, and fuel cell systems Examines electrodeposition, redox-flow batteries, electrolysis, regenerative fuel cells, semiconductors, and other applications of electrochemical engineering principles Overlapping chemical engineering, chemistry, material science, mechanical engineering, and electrical engineering, electrochemical engineering covers a diverse array of phenomena explained by some of the important scientific discoveries of our time. Electrochemical Engineering provides the critical understanding required to work effectively with these processes as they become increasingly central to global sustainability.
