Preface of Electrolytes for Lithium and Lithium Ion Batteries PDF

Lithium-ion (Li-ion) batteries were first introduced into the marketplace by Sony in 1991 to power a video camera. Since then, Li-ion batteries have become part of our daily lives—powering a wide range of mobile electronic devices and power tools. The electrolyte is a key component of a Li-ion battery. Current electrolytes are the result of many years of research and development and play a key role in providing good performance for applications.

New and more challenging battery requirements for power tools, hybrid electric vehicles, plug-in electric vehicles, and stand-by power sources for communications and modern airplanes require a signifi cant advance in battery chemistry. The batteries needed are often of higher voltages and higher energy content. Furthermore, they will be exposed to extremes of temperature with the necessity of still providing long cycle and storage life and assured user safety. A new class of electrolytes is needed to meet these demands.

The new electrolytes must not only provide good ionic conduction over a wide range of ambient temperatures but also provide good chemical stability and compatibility with the more reactive electrode materials that are required to achieve higher battery-specifi c energy and power. With the demand for higher energy density Li-ion batteries, recent development trends favor the use of higher voltage cathodes such as 4.7 V for LiNi 0.5 Mn 1.5 O 4 and 4.8 V LiCoPO 4 , higher capacity cathodes such as layer–layer composite and layer–spinel composite made of Li[Ni,Mn,Co]O 2 with a capacity in the range of 250–300 mA h/g versus 140 mA h/g for LiCoO 2 cathodes used today in commercial cells, and higher capacity Li alloy-based anodes such as Li–Sn and Li–Si alloys.

Today’s state-of-the-art electrolytes made of lithium hexafl uorophosphate (LiPF 6 ) dissolved in cyclic carbonate and linear carbonate solvent mixtures with functional additives are not adequate in these new higher energy density electrochemical pairs without losing capacity or power. Looking beyond the horizon, many researchers and institutions intend to utilize sulfur or air as an even higher theoretical capacity cathode and pair with pure Li as an anode pursuing even higher energy density.

The need of compatible electrolytes is also imperative for developing such systems. What we need are better electrolyte materials that are compatible with the chosen electrode materials. The development of better electrolyte materials will require a much better understanding of electrolytes and how they interact with electrode materials.

This book provides an overview of electrolyte research and development in the past 10 years as a foundation for thinking about future directions. A number of books have been devoted to the science and technology of Li-ion batteries in recent years. However, there is no single book giving a comprehensive overview of electrolytes for Li-ion batteries. With the high demand for more robust electrolytes for the improvement of performance and energy density of Li and Li-ion batteries, it is time for a book that covers the electrolyte materials and the understanding of electrolyte and electrode interactions that have been developed in the past 10 years.

This book covers the materials’ aspects of the electrolytes, the state of the understanding of the electrolyte and electrode interactions, and basic understandings of the electrolytes and electrode/electrolyte interaction through computation. We are pleased to provide a ten-chapter book divided in three parts to cover subjects that we believed would make a good reference for researchers and technologists in the field and also for those who are not working in the field but are interested in understanding the basics, challenges, and progress that have been made in the field.
