▎ 摘　　要

NOVELTY - The battery has a separator connected between a positive electrode and a negative electrode of a battery main body. A nitrogen-doped graphene foam part is formed between the positive electrode and the separator. The nitrogen-doped graphene foam part is overlapped with multiple layers. USE - Lithium-sulfur battery. ADVANTAGE - The battery can effectively absorb polysulfide dissolved in the nitrogen-doped graphene foam part to prevent migration of the polysulfide generated from the positive electrode to the negative electrode so as to improve battery positive electrode active material utilization rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium-sulfur battery manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a lithium-sulfur battery.
