Abstract:

High-energy-density lithium-ion batteries are of great importance in alleviating the energy and environmental crisis. The theoretical specific capacity of silicon-based materials is much higher than that of graphite, which is now recognized as the next generation of anode materials for lithium-ion batteries. Since 1999, when the Institute of Physics of the Chinese Academy of Sciences first reported the important role of nanotechnology in improving the performance of silicon negative electrode, it has continued to explore many basic scientific issues and industrial applications of nano silicon-based materials by mainly focusing on the electrochemical mechanism of nano silicon-based negative electrode materials, the dynamic evolution process of their structure and morphology, generation of stress accumulation and cracks, and the three-dimensional feasibility of solid electrolyte interface (SEI) visual research. In this paper, some of these works are summarized and some opinions on the future development of anode materials are present.

Key words: lithium ion battery, anode materials, silicon
