▎ 摘　　要

NOVELTY - A nano-sized composite material is sulfur-loaded nano sulfur/eight-vulcanized five-vanadium/graphene composite material. The eight-vulcanized five-vanadium is mixture of eight-vulcanized five-vanadium and vanadium trioxide. The nano-grade composite material is obtained by taking polystyrene ball as template. The nano sulfur/eight-vulcanized five-vanadium/graphene composite material has porous three-dimensional layered structure. USE - Method for preparing a nano-sized composite material for an anode of a lithium sulfur battery. ADVANTAGE - The method enables preparing the nano-sized composite material with rich porous structure, better cycle performance and capacity conservation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of nano-sized composite material
