CONDUCTIVE OXIDE COMPOSITE POWDER, METHOD FOR MANUFACTURING COMPOSITE SOLID ELECTROLYTE FILM USING AEROSOL DEPOSITION METHOD, AND COMPOSITE SOLID ELECTROLYTE FILM HAVING HIGH PERFORMANCE MANUFACTURED THEREBY

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.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) LLT (Comparative example 1); (BB) LLT + LLZ 10 wt% (Example 1); (CC) LLT + LLZ 20 wt% (Example 2); (DD) LLT + LLZ 40 wt% (Example 3); (EE) LLT + LLZ 80 wt% (Example 5); (FF) LLT + LLZ PM8h 80 wt% (Example 7)
