Abstract
A method of depositing silicon on carbon nanomaterials such as vapor grown carbon nanofibers, nanomats, or nanofiber powder is provided. The method includes flowing a silicon-containing precursor gas in contact with the carbon nanomaterial such that silicon is deposited on the exterior surface and within the hollow core of the carbon nanomaterials. A protective carbon coating may be deposited on the silicon-coated nanomaterials. The resulting nanocomposite materials may be used as anodes in lithium ion batteries.
Claims27
A method of depositing silicon on the interior and exterior surfaces of a carbon nanomaterial comprising:
- providing a carbon nanomaterial selected from vapor grown carbon nanofibers, a carbon nanomat, and a powder comprising carbon nanofibers;
- flowing a silicon-containing precursor gas in contact with said carbon nanomaterial for a time sufficient for said gas to decompose and form a silicon coating on said surfaces of said carbon nanomaterial.
