▎ 摘　　要

NOVELTY - Cathode active material for lithium-sulfur battery comprises sulfur particles, which are provided in the internal pores on the surface of porous graphene sheet. USE - Cathode active material for lithium-sulfur battery. ADVANTAGE - The cathode active material for lithium-sulfur battery is manufactured by utilizing porous graphene sheet having broad specific surface area, prevents corrosion by the polysulfide of aluminum, and improves electrode conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a lithium-sulfur battery, which comprises a separation film positioned between the anode, and anode comprises cathode active material, lithium salt and organic solvent; and (2) a method for manufacturing cathode active material for lithium-sulfur battery, which involves introducing sulfur particles into the internal porous surface of the porous graphene sheet.
