Futoshi Matsumoto - Water in Lithium-Ion Batteries

SpringerBriefs in Energy presents concise summaries of cutting-edge research and practical applications in all aspects of Energy. Featuring compact volumes of 50 to 125 pages, the series covers a range of content from professional to academic. Typical topics might include:

Briefs allow authors to present their ideas and readers to absorb them with minimal time investment.

Briefs will be published as part of Springers eBook collection, with millions of users worldwide. In addition, Briefs will be available for individual print and electronic purchase. Briefs are characterized by fast, global electronic dissemination, standard publishing contracts, easy-to-use manuscript preparation and formatting guidelines, and expedited production schedules. We aim for publication 812 weeks after acceptance.

Both solicited and unsolicited manuscripts are considered for publication in this series. Briefs can also arise from the scale up of a planned chapter. Instead of simply contributing to an edited volume, the author gets an authored book with the space necessary to provide more data, fundamentals and background on the subject, methodology, future outlook, etc.

SpringerBriefs in Energy contains a distinct subseries focusing on Energy Analysis and edited by Charles Hall, State University of New York. Books for this subseries will emphasize quantitative accounting of energy use and availability, including the potential and limitations of new technologies in terms of energy returned on energy invested.

Water (H2O) in lithium-ion batteries (LIBs), which are constructed with anodes, cathodes and organic electrolytes that contain lithium salts, can degrade the cell performance and seriously damage the materials. However, because a small amount of H2O in cells contributes to the formation of a solid electrolyte interphase (SEI), the complete removal of H2O from cells lowers battery performance and increases the expense of H2O removal from the battery materials. The optimal concentration of H2O for each battery material has been determined, and these concentrations are maintained with appropriate removal methods and H2O scavengers that were recently developed to establish both high performance and low cost. More recently, to achieve both the safety and low cost of LIBs, the development of anode and cathode preparations by aqueous processes and aqueous LIBs in which aqueous electrolytes containing lithium salts are used as electrolytes has progressed. In this review, information on the H2O content in LIBs, the reactivity of anodes, cathodes and electrolytes with water and the processes underlying H2O resistance in LIB materials is reviewed from the perspective of H2O concentration and LIB stability. The goal of this review is to provide appropriate information concerning the amount of H2O needed in cells to achieve stable and high cell performance.
