Document Type and Number:
WIPO Patent Application WO/2023/089875
Kind Code:
A1
Abstract:
This battery comprises a power generating element that has at least one battery cell that each includes a structure formed by stacking a positive electrode layer, a negative electrode layer, and a solid electrolyte layer located between the positive electrode layer and the negative electrode layer, wherein: a through-hole is provided that penetrates in the stacking direction of each of the at least one battery cell; the cross-sectional area of the through-hole in a direction perpendicular to the stacking direction in the positive electrode layer is greater than the cross-sectional area of the through-hole in a direction perpendicular to the stacking direction in the negative electrode layer; and the inner wall of the through-hole is inclined with respect to the stacking direction.
