WIPO Patent Application WO/2024/014183
Kind Code:
A1
Abstract:
This polymer solid electrolyte contains: an ionic liquid and/or lithium salt; first polyrotaxanes in which first straight chain molecules are included in openings of first circular molecules in a skewered manner; and second polyrotaxanes in which second straight chain molecules are included in openings of second circular molecules in a skewered manner. The polymer solid electrolyte also contains cross-linked polyrotaxanes in which: at least one of the first circular molecules and at least one of the second circular molecules are bonded via a chemical bond; and the inclusion rate achieved by the first circular molecules of the first polyrotaxanes and the inclusion rate achieved by the second circular molecules of the second polyrotaxanes are each 5% or less.
