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.
