▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene/carbon nanotube/phosphotungstic acid/sulfur composite material, comprises uniformly dispersing carbon nanotubes in aqueous graphene oxide solution, then adding phosphotungstic acid to make it evenly mixed, and then carrying out hydrothermal reaction to obtain three-dimensional graphene/carbon nanotube/phosphotungstic acid composite material, and uniformly mixing composite material with sublimed sulfur and then reacting at high temperature in an argon atmosphere to obtain three-dimensional graphene/carbon nanotube/phosphotungstic acid/sulfur composite material. USE - The three-dimensional graphene/carbon nanotube/phosphotungstic acid/sulfur composite material is useful as lithium-sulfur battery anode material (claimed). ADVANTAGE - The composite material: has high electronic conductivity, high specific surface area, high mechanical strength, and excellent chemical stability and flexibility; improves conductivity of the sulfur anode and increase the sulfur load. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional graphene/carbon nanotube/phosphotungstic acid/sulfur composite material prepared by above method.
