Title:
ELECTRICITY STORAGE DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/070676
Kind Code:
A1
Abstract:
This electricity storage device comprises: an electricity storage element in which an electrode portion having end surfaces which are of a laminated and wound electrode foil and are different from each other in polarity; a case having a storage portion that internally stores the electricity storage element; and a current collector component disposed on a bottom portion side of the storage portion and provided with a first connection surface portion that is connected to the electrode portion formed on one end surface of the electricity storage element and a second connection surface portion that is connected to an inner wall surface of the case in the storage portion. This makes it possible to increase connectivity by securing a large number of connection areas for the current collector member to the electricity storage element and the case and to achieve simpler manufacturing work for the electricity storage device.
