Abstract:

With the progress of globalization and the increasing demand of energy, people are focusing on developing novel devices for energy storage. Compared with other storage batteries, lithium-ion battery (LIB) is a kind of chemical power sources with the best comprehensive performances, such as high specific energy, long cycle life, small volume, light weight, non-memory, and environment friendly, etc. LIB is widely applied to information technology, electric vehicles & hybrid-electric vehicles, aeronautics & astronautics, etc. The key point of LIB technology and industry are the development of novel lithium-storage materials and electrolyte materials. In this work, by analyzing the technology and industrialization of LIB as well as its application, especially in aeronautics, it is concluded that LIB industry in China has been dramatically developed. However, there are still many problems and weakness in the industry comparing to international advanced level, it is required to develop suitable LIB system and improve the manufacturing technology.

Key words: lithium-ion batteries, cathode materials, anode materials, electrolyte, aeronautics and astronautics
