A free-standing fluorinated graphene (F-graphene) was fabricated by the simple liquid exfoliation of a fluorinated graphite (F-graphite) in a 2-propanol/water mixture, and was used as the cathode material of primary lithium ion batteries. As-prepared F-graphene as a very high fluorine content (49.7at%), and an amorphous-like two-dimensional nanostructure. These features facilitate the rapid diffusion...
Polyacrylonitrile-based carbon fiber bundles, with two sides fixed, were heated in a graphitization furnace with temperature profiles similar to those used in the preparation of carbon/carbon composites. The microstructure of the microvoids formed was characterized by small-angle X-ray scattering and high resolution transmission electron microscopy (HR-TEM). Results showed that the average radius...
