Document Type and Number:
WIPO Patent Application WO/2023/198031
Kind Code:
A1
Abstract:
Disclosed in the present invention are an inorganic oxide solid electrolyte dispersion liquid with a stable solid content for a battery, and a preparation method therefor and the use thereof. The inorganic oxide solid electrolyte dispersion liquid of the present invention is comprised of a granular inorganic oxide solid electrolyte and a solvent, and is free of additives, wherein the solvent in the dispersion liquid is an aprotic solvent having a polarity of 4-8; and the solid content of the dispersion liquid is 40-85wt%. Within the solid content range, the inorganic oxide solid electrolyte dispersion liquid of the present invention is free of particle agglomeration, and has high stability, such that costs for the storage, transportation and use thereof can be reduced. Because the solid content is relatively high, less solvents are used in the dispersion liquid, such that the preparation cost of the dispersion liquid can be effectively reduced.
