CONDUCTIVITY OXIDE COMPOSITE POWDER, METHOD OF MANUFACTURING FOR COMPOSITE SOLID ELECTROLYTE FILM USING AEROSOL DEPOSITION METHOD USING THE SAME AND COMPOSITE SOLID ELECTROLYTE FILM HAVING HIGH PERFORMANCE USING THE SAME

摘要

Disclosed are conductive oxide composite powder, a method for manufacturing a composite solid electrolyte film capable of suppressing a reaction between two materials of the composite powder through the control of an aerosol deposition (AD) process, and a composite solid electrolyte film manufactured thereby. The method for manufacturing a composite solid electrolyte film according to the present invention comprises: (a) a step of preparing a composite powder of a Li-La-Ti-O based powder and a Li-La-Zr-O based powder; and (b) a step of forming a coating layer by spraying the composite powder onto a substrate using the aerosol deposition method.
