The invention discloses a thin-wall local graphitization porous carbon sphere material, a preparation method thereof and application thereof in a lithium sulfur battery. The porous carbon sphere material is a local graphitization porous carbon nanosphere with thin wall holes; the preparation method of the thin-wall local graphitization porous carbon sphere material comprises the steps that water-base resin, water-soluble inorganic salt, a surface active agent and transition metal salts are dissolved into water to obtain a spraying solution; the spraying solution is sprayed and dried to obtaina local graphitization porous carbon nanosphere precursor; the local graphitization porous carbon nanosphere precursor is subjected to pyrolysis to obtain the thin-wall local graphitization porous carbon sphere material. The preparation method is simple in technology and good in repeatability, the prepared thin-wall local graphitization porous carbon sphere material has the advantages of being good in electrical conductivity, large in aperture, high in specific surface area and the like, the thin-wall local graphitization porous carbon sphere material is applied to a lithium sulfur battery sulfur carrier, the high specific capacity, long cycling stability and high rate capability are achieved, and the wide application prospect is achieved.
