The present invention provides a step of preparing a lithium (Li) precursor, a manganese (Mn) precursor and a phosphorus (P) precursor to form a cathode material, and a lithium (Li) precursor, aluminum (Al) to form a solid electrolyte Preparing a precursor, a titanium (Ti) precursor, and a phosphorus (P) precursor, and mixing the precursors for forming the cathode material and the precursors for forming the solid electrolyte in a solvent to form a precursor solution; , generating droplets from the precursor solution, spraying the droplets into a pre-heated reactor, and collecting the cathode material-solid electrolyte composite powder produced by thermal decomposition of the droplets in the reactor in a collector It relates to a method for producing a cathode material-solid electrolyte composite powder. According to the present invention, since the grinding process and the coating process are unnecessary, the manufacturing process is simple, the production cost and time can be reduced, and it has a spherical shape, and the interfacial resistance can be lowered because the cathode material and the solid electrolyte are complexed. |
