Si Carbon Composite Anode

Si-Carbon Composite Anode for Lithium-ion Batteries, 300g

In this Si-Carbon composite, the Si amount is controlled lower than 10% by weight. Si is an active component that contributes to the high lithium storage capacity at the same time the graphite/amorphous carbon matrix significantly buffers the volume expansion of Si, improves electronic conductivity, and stabilizes the SEI layers of the Si particles. This is a commercial product used in pouch cells and cylindrical cells.

With the increase of Si content in the composite, the capacity is increased while the cycling performance gets worse.
