| description | The invention discloses application of an O-Co3S4/CP material capable of adsorbing lithium polysulfide as a positive electrode material of a lithium-sulfur battery. The O-Co3S4/CP material comprises carbon paper and oxygen-doped cobaltosic sulfide, the oxygen-doped cobaltosic sulfide grows on a fiber skeleton of the carbon paper and is of a hollow sheet scabbard-shaped structure; and the oxygen content of the O-Co3S4/CP material is 10 to 35 at%. The experimental preparation method is simple, mild and environment-friendly, oxygen doping can be carried out in situ while vulcanization is carried out, the prepared material has good adsorption performance on lithium polysulfide when the material is used as the positive electrode material of the lithium-sulfur battery, and the assembled lithium-sulfur battery has good cycle stability.
