Why is the key to the lithium ion battery electrolyte components?

Source: 2020 - 04 - 11 hits out: time are key components in lithium ion battery electrolyte of lithium battery research began in the sixties and seventies of the last century, the early seventy s to achieve the commercialization of the battery. By Japan's SONY ( 索尼) The development of lithium ion secondary battery, also as the power supply of the camera to the market in 1991. At present, the excellent performance of rechargeable lithium ion battery has been widely used in computer and various mobile devices. To further develop suitable for different areas ( Such as hybrid cars, communications equipment, aircraft spare power supply, etc. ) A new type of high performance lithium ion battery, in order to satisfy the demands of all kinds of equipment's growing power, is a research topic of concern. Electrolytes are key components in lithium ion batteries. Looking for a better performance of electrolyte, understand the electrochemical process of the electrode and electrolyte interface, is the key to further improve the battery performance. The book from the Angle of practice and theory of multiple discussed the synthesis and performance research of high performance of electrolyte and characterization. In addition, the electrode - also includes research Electrolyte interface tools and methods of special section, and the use of quantum chemistry exploring new molecular design method of the electrolyte. Involved from the breadth and depth, and discuss the content of the point of view, they are all unique. The total number of nearly 2000 references at the end of each chapter, is worthy of reference. This shows, the electrolyte is the key component of lithium-ion batteries. Good currently used in commercial lithium ion battery electrolyte is the results of years of research and development, to a breakthrough in lithium ion battery performance plays a key role. Modern aircraft for hybrid electric vehicle power supply and communication power supply and backup power the demand for new power is the power of chemical major challenges. Different devices of lithium ion battery not only has the highest possible output voltage, high capacity and high energy density, but also has a good charge and discharge performance, storage life and safety performance. Must also be used for the battery electrolyte in extreme conditions of high temperature and low temperature show that the ion conductivity and good chemical stability, and good compatibility with all kinds of electrode materials. Considering the requirement of high energy density, the new lithium-ion batteries use a variety of newly developed high potential and high capacity anode materials and different matching of anode material, so it is necessary to explore new electrolyte is suitable for the battery, on the basis of deep understanding of the electrochemical behavior and interface features. Therefore, it is necessary to explore the synthesis, analysis, and scientists in the field of computational chemistry is an effective means of mutual cooperation, to promote research and development of new type high energy density lithium ion batteries. Chapter reviews in detail and a large number of recent provides the reference for the researchers and technicians for lithium ion battery electrolyte in the valuable advice and information.
