Ebook: Water in Lithium-Ion Batteries

This book reviews the impact of water content in lithium-ion batteries (LIBs) as well as the reactivity of anodes, cathodes and electrolytes with water and processes that provide water-resistance to materials in LIBs. Water in LIBs which were constructed with anode, cathode and organic electrolyte containing lithium salts can degrade the cell performance and seriously damage the materials present. However, because a small amount of water in cells contributes to the formation of the solid electrolyte interphase, complete removal of water from cells lowers the battery performance and increases costs due to removal of water from the battery materials. This book presents the optimal concentration of water for each battery material along with appropriate removal methods and water-scavengers which were developed recently to establish both high performance and lower costs. Moreover this book describes the development of anodes and cathodes prepared by aqueous process and aqueous LIBs in which aqueous electrolytes containing lithium salts are used as an electrolyte. This book will be useful not only for academic researchers but also for company researchers who deal with LIBs.


About the authors
Professor Futoshi Matsumoto at Kanagawa University in Japan. He completed his graduate studies at Tokyo Institute of Technology in 1997 and was a postdoctoral research associate at Tokyo University of Agriculture and Technology for 1998-1999. After a brief stay at Tokyo University of Science and Kanagawa Academy of Science and Technology, he moved to Cornell in 2005. For three years, he researched electrocatalyst for fuel cell as research associate with Prof. H.D. Abruna. From 2008-2009, he worked at Wildcat Discovery Technology Inc. at San Diego in USA to develop the high-throughput technology for lithium-ion battery materials. He returned to Japan and started his research at Kanagawa University at 2010.
