Ultrafine grinding, disintegration and classification equipment for lithium battery silicon-carbon negative electrode materials

In recent years, with the development of battery electrode materials, lithium-ion battery technology has developed rapidly. At present, lithium-cobalt batteries have expanded to battery systems such as ternary system, lithium manganese oxide, lithium iron phosphate, and silicon-carbon negative electrode.

The new silicon-carbon negative electrode lithium-ion battery breaks through the inherent limitations of graphite as a negative electrode, and its performance is significantly better than that of traditional lithium-ion batteries. It has become one of the more promising energy storage batteries.

Why do lithium-ion batteries use silicon carbon as negative electrode materials?

With the continuous improvement of energy density requirements, the graphite negative electrode material is restricted by the theoretical capacity of 372mAh/g, and the compaction density has basically reached its limit after several years of improvement.

On the basis of the continuous improvement of energy density, silicon-carbon negative electrode material has become a negative electrode material with high energy density requirements. The theoretical capacity of silicon is 4200mAh/g.

Compared with graphite negative electrode, silicon-carbon negative electrode has higher mass energy density and volume energy density. The mass energy density of lithium-ion batteries using silicon negative electrode material can be increased by more than 8%, and the volume energy density can be increased by more than 10%. Therefore, silicon negative electrode materials will have very broad application prospects.
