Renewable energies such as solar, hydro or wind power are abundant in principle but subject to strong fluctuations. Therefore, development of new technologies for storage of these renewable energies is of special interest. Electrochemical technologies are ideal candidates for the use of excess current; consequently, an increased electrification of chemical processes is expected. In this respect, there are different pathways to utilize excess current electrochemically. Perhaps the most accepted and discussed solutions involve intermediate energy storage in either chemical energy carriers (such as hydrogen via water electrolysis) or electrochemical energy storage devices (like batteries). Additionally, excess current can put to other uses, such for solutions to environmental issues or for construction purposes, rather than being stored for later use.
The printing of the seventh edition of the book has provided the author with an opportunity to completely go through the text.Minor Additions and Improvements have been carried out,wherever needed.All the figure work has been redone on computer,with the result that all the figures are clear and sharp.The author is really thankful to M/s S.Chand & Company Ltd. for doing an excellent job in publishing the latest edition of the book.
Edited by experts, one of whom developed the technology, Electrolytic In-Process Dressing (ELID) Technologies: Fundamentals and Applications provides an overview of ELID processes with correlations between the main parameters, describes ELID operations, and illustrates the concepts with case studies. The book’s authoritative coverage of major concepts and applications of this emerging technology makes it a definitive reference. The book delineates the fundamentals, the chemistry and physics, and the hardware required by the process, then explores the application of ELID to different configurations of grinding. It discusses ELID grinding methods, lapping/grinding process, honing, and an original method of ELID grinding of free forms surfaces using an original design. The book also provides case studies in areas such as: Nano ultra-precision ELID and the latest developments in ELID nano-grinding Glass ceramic mirrors, small lens, and large scale optics New concept of micro-workshop, where all the machines tools and measurement devices are table-top machines with high accuracy Successful applications of ELID technology in the optics, semiconductor, mold and die, and micro-tools industries Surface modifications as a future method for obtaining complex modifications of surfaces by using ELID in combination with other methods Arguably the first comprehensive review of this emerging technology, this book combines information drawn from experts and the literature to provide a practical reference for the field. The editors have put together a resource that anticipates many of the questions that will arise from the investigation of ELID methods and applications.
