    • A negative-electrode terminal for a cell in which separation between a first metal layer and a second metal layer hardly takes place is provided by suppressing excess formation of an intermetallic compound on a bond interface between the first metal layer and the second metal layer. This negative-electrode terminal for a cell includes a clad portion formed by bonding a first metal layer made of Al or an Al alloy and a second metal layer containing Ni and Cu and consisting of one or a plurality of layers to each other. The first metal layer includes a connected region connected with a cell terminal connecting plate and a stacked region adjacent to the connected region on the side of the same surface, while the second metal layer is bonded to the first metal layer in the stacked region and configured to be connectable to cell negative electrodes of cells.
    • 通过抑制金属间化合物在第一金属层和第二金属层之间的键合界面上的过量形成,提供了几乎不发生第一金属层和第二金属层之间的间隔的电池的负极端子。 用于电池的负极端子包括通过将由Al或Al合金制成的第一金属层和包含Ni和Cu的第二金属层彼此结合并由一个或多个层组成的包层部分。 第一金属层包括与电池端子连接板连接的连接区域和与相同表面侧的连接区域相邻的堆叠区域,而第二金属层在堆叠区域中接合到第一金属层并且被配置 可连接到细胞的细胞负极。
