Alfa Chemistry can customize graphene-based silicon-carbon composites. For different battery systems, we select the appropriate graphene and use professional technology to make the appropriate composite material. We manufacture the best quality customized graphene-based silicon-carbon composites, which has a high service life and can meet the needs of customers.
Chemical Vapor Deposition (CVD):
CVD is widely used in microfabrication processes to deposit materials in various forms (fibers, nanofibers, nanotubes, graphene).
Physical Vapor Deposition (PVD):
PVD is characterized by the process in which the material changes from the condensed phase to the gas phase and then back to the film condensed phase. The most common PVD processes are sputtering and evaporation.
In order to prevent the inert phase of Si/C, the reaction temperature is usually controlled below 1200 ℃.
MA performs repeated cold welding, fracturing and re-welding on the mixed powder particles in a high-energy ball mill to produce a uniform material. Materials prepared by MA generally have smaller particles, a larger specific surface area and a more uniform structure.
The silicon salt is a precursor, which is hydrolytically condensed in the liquid phase, added with a carbon source, and then dried and sintered to prepare a silicon/carbon anode material.
