▎ 摘　　要

NOVELTY - Composite material comprises graphene and dichlorophthalocyanine tin-n polymers attached to the graphene surface. USE - The composite material is useful as graphite alkeny intercalation film (claimed). ADVANTAGE - The composite material: accelerates the redox reaction kinetic rate of lithium polysulfide (LiPSs); reduces the accumulation of insoluble solid product lithium persulfide/lithium sulfide; inhibits the migration and diffusion of LiPSs; and exhibits excellent electrochemical performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the composite material; lithium-sulfur battery anode; preparing lithium-sulfur battery anode; and lithium-sulfur battery.
