▎ 摘  要

NOVELTY - Composite particulates comprise active material particles, and single graphene sheet or graphene sheets which surrounds the active material particles and surface of composite particulates. The graphene sheets provide electron-conducting path. USE - Composite particulates used for anode for lithium battery (all claimed) such as lithium-ion battery for electric vehicle. ADVANTAGE - The composite particulates have excellent thermal conductivity, tap density, capacity, and cycle characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) anode; (2) cathode; (3) lithium battery; and (4) preparation of the composite particulate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-enhanced anode particulates.
