Document Type and Number:
WIPO Patent Application WO/2022/230635
Kind Code:
A1
Abstract:
The present invention provides: a solid electrolyte which is able to be reduced in gelation; an electrolyte composition; an electrolyte sheet; and a power storage device. This solid electrolyte (18) has a garnet structure that contains Li, La, Zr and O; and with respect to particles (21) having a particle diameter that is equal to or greater than the particle diameter at which the integrated frequencies reach 10% in the volume-based particle size distribution of solid electrolyte particles, the number average of the envelopment degree that is defined as the value of (area inside an outline (22))/(area inside an envelope (23)) of each particle is 0.8 or more. This electrolyte composition contains this solid electrolyte, an ionic liquid that contains imidazolium cations, a lithium salt, and a polymer that contains -CH2CF2-. This electrolyte sheet is formed of this electrolyte composition. This power storage device comprises an electrolyte layer that is formed of this electrolyte composition.
