▎ 摘  要

NOVELTY - The material has sulfur-rich polymer formed with graphene i.e. reduction-oxidation graphene. An internal structure of the sulfur-rich polymer functions as an interpenetrating network structure. The graphene is doped in the sulfur-rich polymer such that particle size of the sulfur-rich polymer is 100-300 meshes. A prepared sulfur-rich polymer is crushed into powder. A solvent is added to obtain a solution, and the solution is sufficiently stirred. Ultrasonic dispersion is carried on the graphene in the solvent to obtain a suspension. The solutions are mixed while continuing ultrasonic dispersion and stirring operations. The solvent is finally removed, and a product is dried to obtain the material for a lithium-sulfur battery. The sulfur-rich polymer is made between fifteen alkyl phenol phenolic resin monomer with elemental sulfur to obtain preparation, where resin monomer is pentadecyl phenol, paraformaldehyde and amine, which is aromatic amine or aliphatic amine. USE - Anode material e.g. aniline-type positive electrode material and diamine-type positive electrode material, for a lithium-sulfur battery utilized for a mobile electronic equipment and an electric driven vehicle. ADVANTAGE - The material has high conductivity, better cycle performance and prolonged service life, and is simple to operate, inexpensive and easy in large-scale manufacturing and commercialization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing an anode material for a lithium-sulfur battery. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for preparing an anode material for a lithium-sulfur battery. '(Drawing includes non-English language text)'
