▎ 摘　　要

NOVELTY - A three-dimensional graphene-hollow carbon sphere nanocomposite comprises hollow sphere with a carbon graphene composition, where the distribution of the hollow carbon sphere three-dimensional network structure comprises graphene. USE - Three-dimensional graphene-hollow carbon sphere nanocomposite for use in lithium-sulfur battery cathode material. ADVANTAGE - The nanocomposite has rapid electronic conduction, inhibits lithium polysulfide dissolution and shuttle, during cycling volume change, and can be prepared in simple and effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing three-dimensional graphene-hollow carbon sphere nanocomposite.
