▎ 摘　　要

NOVELTY - The material is formed by free radical polymer and graphene, where ratio of mass parts of the free radical polymer to graphene is 1-20: 1-10. A chain of the free radical polymer is connected with 2, 2, 6, 6-tetramethyl piperidinooxyl-1-oxygen free radical. USE - Free radical polymer/graphene composite material for use as anode electrode material of energy-storage element i.e. lithium ion battery (all claimed) ADVANTAGE - The material is simple to process, easy to obtain and suitable for large scale production, and has high application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a free radical polymer/graphene composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic representation of a free radical polymer/graphene composite material.
