Title:
ELECTRICAL STORAGE ELEMENT AND METHOD FOR MANUFACTURING ELECTRICAL STORAGE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/141694
Kind Code:
A1
Abstract:
This electrical storage element comprises a negative electrode terminal (205), a negative electrode current collector (130), and a connecting section (230) that connects a terminal section (210) of the negative electrode terminal (205) and the negative electrode current collector (130). The terminal section (210) of the negative electrode terminal (205) has a tube section (213), a main body section (211) side of which has a bottom and a negative electrode current collector (130) side of which is open. The connecting section (230) is inserted into the tube section (213) and is bonded to the tube section (213). A first connecting section side recess section (233) and a second connecting section side recess section (234) are formed in an outer surface of the connecting section (230). A first tube section inner surface side projection section (217) and a second tube section inner surface side projection section (217) that are fitted to the first connecting section side recess section (233) and the second connecting section side recess section (234) of the connecting section (230) are formed on an inner surface of the tube section (213).
