▎ 摘　　要

NOVELTY - A manganese dioxide/graphene barrier layer-based lithium-sulfur battery comprises sulfur containing positive pole, diaphragm, electrolyte, metal lithium cathode and foam nickel current collector, where the sulfur anode surface is coated with the barrier layer by automatic machine coating, and the barrier layer comprises manganese dioxide/graphene composite-coated surface of the positive electrode active sulfur-containing material. USE - Manganese dioxide/graphene barrier layer-based lithium-sulfur battery. ADVANTAGE - The battery has improved battery electrochemical performance, catalytic activity and adsorption capacity, and increased conductivity.
