Si-Carbon Composite Anode Description
Silicon-Carbon Composite Anode for lithium-ion batteries, typically in the form of carbon-shelled nanostructures, has already been broadly researched as prospective candidates for replacing graphite in anodes. 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. It is used in pouch cells and cylindrical cells. The pairing of silicon with carbon features a favorable combination of both materials, including the high lithiation capacity of silicon, as well as the exceptional mechanical and conductive qualities of carbon.
