u003cpu003e The research on lithium batteries began in the 1960s and 1970s, and the commercialization of primary batteries was realized in the early 1970s. The lithium-ion secondary battery developed by Japan’s SONY was also introduced to the market in 1991 and used as a power source for video cameras. At present, high-performance rechargeable lithium-ion batteries have been widely used in computers and various mobile devices. Further development of new high-performance lithium-ion batteries suitable for different fields (for example, hybrid electric vehicles, communication equipment, and aircraft backup power sources, etc.) to meet the increasing power requirements of various devices is a research topic that has attracted much attention The electrolyte is a key component of lithium-ion batteries. Seeking an electrolyte with better performance and understanding the electrochemical process at the interface between the electrode and the electrolyte is the key to further improving the performance of the battery. This book has multiple perspectives from practice and theory. Discussed the research and characterization of high-performance electrolyte exploration, synthesis and performance, discussed the progress in recent years and possible future research directions. It also included the discussion of tools and methodology for electrode-electrolyte interface research and the use of quantum chemistry methods. Special chapters for exploring the molecular design methods of new electrolytes. From the breadth and depth of the content and the perspective of discussion, they have their own uniqueness. The total number of references at the end of each chapter is nearly 2000, which is worth referring to Literature resources in this field.u003c/pu003eu003cpu003eu003cpu003e It can be concluded that the electrolyte is a key component of lithium-ion batteries'. Today’s superior performance electrolytes for commercial lithium-ion batteries are the result of years of research and development. It has played a key role in achieving breakthroughs in the performance of lithium-ion batteries. The demand for new power sources such as hybrid electric vehicle power and communications and modern aircraft backup power is a huge challenge for power chemistry. Lithium-ion batteries used in different devices are not only To have the highest possible output voltage, high capacity and high energy density, it must also have good charge and discharge performance, storage life and safety characteristics. The electrolyte used in the battery must also show good performance under extreme conditions of high and low temperature Ion conductivity and chemical stability, and good compatibility with various electrode materials. Taking into account the requirements of high energy density, new lithium-ion batteries often use a variety of newly developed high-potential or high-capacity cathode materials and matching Different anode materials, therefore, it is necessary to explore a new type of electrolyte that is compatible with it on the basis of an in-depth understanding of the electrochemical behavior and interface characteristics of the battery. For this reason, it is necessary to explore the cooperation of scientists engaged in synthetic chemistry, analytical chemistry, and computational chemistry. An effective way to promote the research and development of new high-energy density lithium-ion batteries. The detailed reviews of each chapter in this book and the large number of recent references attached provide researchers and technicians with the value of electrolytes in lithium-ion batteries.
