▎ 摘　　要

NOVELTY - A preparation of graphene/lithium composite material, involves mixing graphene oxide particles and lithium metal particles, generating electrostatic friction between the graphene oxide particles and lithium metal particles and generating spontaneous redox reaction, obtaining graphene/lithium particles in which graphene is bonded to the surface of lithium metal particles by chemical bonding, pressing the granule blank formed by the graphene/lithium granule into a sheet, and repeatedly folding and pressing the sheet. Each of the above steps is carried out in an anhydrous and oxygen-free environment. USE - Preparation of graphene/lithium composite material used in cathode of lithium battery (all claimed). ADVANTAGE - The method does not uses an organic solvent and high temperature, has simple operation and no harsh preparation conditions, and is suitable for the large-scale preparation of the graphene/lithium composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene/lithium composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of graphene/lithium composite material. Stacked graphene layer (10) Lithium layer (20)
