▎ 摘　　要

NOVELTY - A composite material comprises sulfonated graphene, polyaniline nanoarray and elemental sulfur. USE - Composite material is used as anode material for secondary aluminum battery (claimed). ADVANTAGE - The composite material has excellent electroconductivity and sulfur adsorption capacity, and is prepared by a simple process. The secondary aluminum battery having excellent capacity and cycle performance, is manufactured using the composite material, by a simple process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of composite material, which involves uniformly mixing sulfonated graphene, polyaniline nanoarray and elemental sulfur, heating at 130-180 degrees C for 1-12 hours under inert gas protection atmosphere and cooling; and (2) secondary aluminum battery.
