Title:
SOLID ELECTROLYTE CERAMIC AND SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/107801
Kind Code:
A1
Abstract:
The present invention provides a solid electrolyte ceramic which more sufficiently suppresses an increase in the electron conductivity due to operation of a solid-state battery, while having excellent ion conductivity, and which has a higher relative density. The present invention relates to a solid electrolyte ceramic which has a garnet crystal structure, while containing at least lithium (Li), lanthanum (La) and oxygen (O), and additionally containing one or more transition metal elements that are selected from the group consisting of cobalt (Co), nickel (Ni), manganese (Mn) and iron (Fe), wherein if X (mol%) is the content of Li and Y (mol%) is the total content of the one or more transition metal elements, one of the relational expressions (1) to (3) described below is satisfied.
(1): 0.01 ≤ Y ≤ 4.00 within the range of 221 ≤ X < 227
(2): 0.01 ≤ Y ≤ 6.00 within the range of 227 ≤ X < 237
(3): 0.01 ≤ Y ≤ 8.00 within the range of 237 ≤ X ≤ 250
