The invention discloses a lithium-rich manganese-based positive electrode material compositely coated with an alpha-ZrP-conducting polymer, a preparation method of the lithium-rich manganese-based positive electrode material and application of a solid-state battery. According to the material, a bulk phase modified lithium-rich manganese-based material is used as a core, and a composite coating layer composed of a delaminated alpha-ZrP nanosheet and a conductive polymer is constructed on the surface of the lithium-rich manganese-based material. The composite coating layer can realize internal proton self-exchange response with the conductive polymer based on the solid acid characteristic of alpha-ZrP, and an overpass type rapid ion-electron dual-transmission channel is formed in the material body. Meanwhile, the coating layer is used as a compact physical and chemical barrier, and harmful side reactions between the positive electrode and the solid electrolyte are effectively blocked. When the prepared positive electrode material is applied to a solid-state battery, high first-circle coulombic efficiency and excellent cycling stability and rate capability are shown, and the two core problems of unstable interface and slow dynamics of a lithium-rich manganese-based material in the solid-state battery are effectively solved.
