Title:
POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/120171
Kind Code:
A1
Abstract:
This power storage device comprises: an electrode laminate including a plurality of electrodes; a separator; and a sealing part made of resin. The plurality of electrodes include a bipolar electrode. The bipolar electrode has: a current collector; a positive electrode active material layer; and a negative electrode active material layer. The sealing part includes: a first adhesive part adhered to the current collector; a second adhesive part adhered to the current collector; a first reinforcing part bonded to the first adhesive part; a second reinforcing part bonded to the second adhesive part; and an end-surface welded part. The moisture vapor transmission rate of the end-surface welded part is lower than the moisture vapor transmission rate of the first adhesive part and the moisture vapor transmission rate of the second adhesive part.
