Brief Introduction to Porous Carbon for Silicon Deposition
Silicon based anode materials are the most anticipated next-generation battery materials. For vapor deposited silicon carbon, the core is to produce a porous carbon framework at low cost to store silicon, and buffer the volume expansion during the lithium insertion process through the pores inside the porous carbon. Therefore, the expansion rate is low and the cycle is excellent. The carbon skeleton not only has low production cost, but also has good lithium storage capacity. In addition, the carbon skeleton itself has a low density and light weight, making the material energy density high.
Characteristic
