▎ 摘  要

NOVELTY - The material has a continuous network of crystalline graphite region (602) that is integrated and in electrical contact with a composite. The composite consists of a disordered graphene sheets and an electrically active material such as silicon is in contact with disordered graphene sheets. The electrically active material has nanoparticles that are dispersed between the disordered graphene sheets. The thermal reduction of the silicon-graphene oxide composite material is carried out at a temperature of 550-850 degrees C. USE - Electrode material for use in Li ion batteries (claimed). ADVANTAGE - The graphite regions that are made from stacks of graphene sheets are electrically conducting, mechanically strong, and easy to prepare from exfoliated graphite and possess limited Li storage capacities, consistent with carbon-based materials and are well-suited as supports for high-storage capacity materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) lithium ion battery; and (2) method for making electrode material. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of Electrode material. Graphite region (602) Composite material (604)
