Document Type and Number:
WIPO Patent Application WO/2024/048411
Kind Code:
A1
Abstract:
A solid electrolyte according to one aspect of the present invention comprises elemental lithium, elemental phosphorus, elemental sulfur, elemental halogen, and elemental aluminum, has a crystal structure, and satisfies both of expressions (a1) and (b1) or both of expressions (a2) and (b2). (a1): 2.89<[Li/P]-[X/P]≤3.15. (b1): 0.01≤[Al/P]≤0.10. (a2): 2.84<[Li/P]-[X/P]≤2.89. (b2): 0.02≤[Al/P]≤0.10. In expressions (a1), (b1), (a2), and (b2), [Li/P] is the molar ratio of elemental lithium content with respect to elemental phosphorus content, [X/P] is the molar ratio of elemental halogen content with respect to elemental phosphorus content, and [Al/P] is the molar ratio of elemental aluminum content with respect to elemental phosphorus content.
