Document Type and Number:
WIPO Patent Application WO/2024/095916
Kind Code:
A1
Abstract:
Provided are: a production method for a solid electrolyte sheet that makes it possible to suppress shrinkage of a solid electrolyte sheet during a firing step when the sheet is formed; and a solid electrolyte sheet. A solid electrolyte sheet 10 comprises a first solid electrolyte layer 12 that is a dense layer and a second solid electrolyte layer 13 that is a porous layer that is provided on at least one principal surface 12a, 12b of the first solid electrolyte layer 12. The average crystal grain size of a first solid electrolyte that constitutes the first solid electrolyte layer 12 is smaller than the average crystal grain size of a second solid electrolyte that constitutes the second solid electrolyte layer 13.
