Abstract
The present disclosure is directed to silica-carbon composite materials including a low bulk density carbon material having a skeletal framework of carbon nanofibers, the skeletal framework forming a pore structure comprising an array of interconnected pores. The silica-carbon composite materials further include a conformal coating layer of silica on the carbon nanofibers. Further provided are methods for preparation of the silica-carbon composite materials, and methods for reduction of the silica-carbon composite materials to provide silicon-carbon composite materials.
