application of nano silicon powder

Silicon has excellent electrochemical performance, its theoretical lithium storage capacity is as high as 4200mAh/g, and its lithium intercalation potential is also low.
The lithium intercalation voltage platform of silicon is slightly higher than that of graphite, and the voltage platform is stable, and the phenomenon of lithium deposition on
the surface is difficult to occur during charging, so its safety performance is also better than that of graphite. In addition, silicon is abundant in the earth's crust and has a wide
range of sources. It is not only cheap, but also non-toxic. It has great advantages and broad prospects for application in silicon-based negative electrode materials.
