Carbon sphere, base material, positive pole plate, battery and corresponding preparation or assembly method

The invention discloses a carbon sphere, a preparation method thereof, a positive electrode base material, a preparation method of the positive electrode base material, a positive pole plate, a lithium-sulfur battery and an assembly method of the lithium-sulfur battery. The carbon sphere has a porous structure and a hollow structure, wherein the porous structure comprises a marcopore structure andalso comprises at least one of a micropore structure and a mesopore structure, and the marcopore structure is interconnected with at least one of the micropore structure and the mesopore structure. With the carbon sphere disclosed by the scheme, the defects that the conductivity is poor, the capacity attenuation and the volume change are easily caused and the like in the prior art can be overcome, and the beneficial effects that the conductivity is good and the capacity attenuation and the volume change are difficult to cause are achieved. 本发明公开了种碳球及其制备方法、正极基体材料及其制备方法、正极片、锂硫电池及其组装方法，该碳球具有多孔结构和空心结构；其中，所述多孔结构，包括：大孔结构；还
