▎ 摘　　要

NOVELTY - An anode material (3) comprises oxygen-containing carbon (1B), where oxygen is in the form of functional groups and distributed from the surface to the inside of the carbon, and carbon has an interlayer space d002 of 0.335-0.45 nm; and porous graphene layer covering the oxygen-containing carbon and being in the form of monolayer or layer graphene. USE - An anode material for lithium ion battery (claimed). ADVANTAGE - The anode material can simultaneously satisfy high capacity, fast chargeable capability, and good cyclability for lithium ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) lithium ion battery comprising positive electrode and negative electrode, where negative electrode contains the anode material; and (2) fabrication of anode material for lithium ion battery which involves preparing starting carbon material (1A), wet-oxidizing (S1) the starting carbon material by acid treatment and alkaline compound treatment, heat treating (S2) the carbon material at 500-1000 degrees C for 1-24 hours under an inert atmosphere, and mixing (S3) the heat-treated carbon material (1C) with porous graphenes to obtain a porous graphene coated carbon material (3). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the anode material fabrication process.
