ABSTRACT

As an anode material, the theoretical specific capacity of silicon is more than ten times that of graphite materials, and its delithiation potential is low. Therefore, it has become a research focus in the field of electronic devices, electronic vehicles and renewable energy storage systems. However, the volume expansion of silicon during charge and discharge process will cause the material to pulverize, which will reduce Coulomb efficiency and shorten the service life. In order to solve these problems, researchers have made a lot of efforts. This article analyzes and discusses the preparation methods, electrochemical properties of representative silicon-based materials, including silicon nano-particles, siliconcarbon composite materials, and SiOx (0
