Abstract

Provided are a positive electrode material coated with a mixed solid-state electrolyte and a preparation method thereof, a positive electrode plate, a solid-state battery, and an electrical-related device. The positive electrode material coated with the mixed solid-state electrolyte includes a positive electrode material and a mixed solid-state electrolyte coating the surface of the positive electrode material, and the mixed solid-state electrolyte includes an oxide solid-state electrolyte, a sulfide solid-state electrolyte, and a halide solid-state electrolyte. By designing the positive electrode material coated with the mixed solid-state electrolyte, the oxide solid-state electrolyte provides mechanical properties, the sulfide solid-state electrolyte provides ionic conductivity, and the halide solid-state electrolyte provides a stable interface. The combination of the three solid-state electrolytes can effectively improve the structural stability and conductivity of the positive electrode material, thereby improving the cycle stability of the battery.
