▎ 摘　　要

NOVELTY - The material has a base material arranged with a carbon nano tube sponge. A graphene material is coated with a surface that is arranged with elemental sulfur. The carbon nano tube sponge is formed with the elemental sulfur. USE - Graphene coated carbon-sulphur composite anode material. ADVANTAGE - The material realizes three-dimensional network structure and large surface area, reduces contact resistance effect of insulating sulfur and improves composite circulation property of secondary aluminum battery without need of electric conduction agent and adhesive, and has low production cost and high safety, and is easy to absorb sulfur dissolution and active substance and environment-friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene coated carbon-sulphur composite anode material preparation method (2) a secondary aluminum battery.
