The present application provides a cathode material comprising the following raw materials in parts by weight: 10 parts of a porous carbon conductive agent, 7 to 14 parts of an additive, 38 to 44 parts of an active material, and 32 to 40 parts of a solid electrolyte, wherein the active material comprises sulfur powder, and the additive comprises one or both of phosphorus pentasulfide and phosphorus trisulfide. Elemental sulfur reacts with lithium ions during battery discharge to form lithium sulfide, which can react with the additive to in-situ generate a lithium phosphorus sulfur solid electrolyte. The lithium phosphorus sulfur solid electrolyte not only enables most of the active material to participate in the charge-discharge cycle, improving the utilization rate of the active material, but also forms an ionic conductive network, allowing lithium ions to conduct faster. It also enhances the ionic conductivity of the cathode material, achieving high specific capacity and cycling stability in all-solid-state lithium-sulfur batteries under high areal loading conditions.
