Document Type and Number:

WIPO Patent Application WO/2014/163184

Kind Code:

A1

Abstract:

Provided is a secondary battery collector structure having a small electrical resistance and also provided is a method for forming the secondary battery collector structure. A stir welding portion is formed by friction stir welding so that a positive electrode collector tab layer (27) is not exposed to the surface. In the stir welding portion, a collector (11b) of a positive electrode terminal (11), the positive electrode collector tab layer (27), and a positive electrode presser plate (25) are welded together.
