NEGATIVE ELECTRODE TERMINAL FOR BATTERY AND METHOD FOR PRODUCING NEGATIVE ELECTRODE TERMINAL FOR BATTERY

摘要

Provided is a negative electrode terminal for a battery, wherein a first metal layer and a second metal layer are not easily separated from each other by suppressing the formation of an intermetallic compound at the interface between the first metal layer and the second metal layer. A negative electrode terminal (8) for a battery is composed of a clad material that is formed by joining a first metal layer (80), which has a first region that is connected with a battery terminal connection plate and a second region that is adjacent to the first region on the same surface and which is formed of Al, and a second metal layer (81), which is connected with a negative electrode for a battery and is formed of Ni. The second metal layer is arranged so as to be laminated on the first metal layer in the second region of the first metal layer.
