Abstract: An assembled battery has a battery block configured by stacking a plurality of single batteries, and fixing components fixing the plurality of the single batteries. The fixing components include a pair of end plates disposed at both ends in a stacked direction of the plurality of the single batteries, and a metal band making the plurality of the single batteries in a compressed state by coupling end parts of the pair of the end plates each other. Each of the pair of the end plates has a peripheral part and a central part. The pair of the end plates respectively contact both end single batteries located at both ends in the stacked direction at the peripheral parts, and are respectively separated from both end single batteries at the central parts.

Abstract: A dissimilar metal joined body includes a copper material, an aluminum material and a molten mixed portion. The molten mixed portion is configured so that part of the aluminum material is melted and flows into the copper material. The depth from a surface of the copper material which contacts the aluminum material in the molten mixed portion is at least 5 μm and no greater than 30 μm.

Abstract: Weld structures of metal members include: a first member; and a second member that is layered together with the first member, wherein at least one first solidified part that extends from a surface of the first member to the inside of the first member, at least one second solidified part that is formed by a molten area extending through the first member and the second member, and at least one third solidified member that is formed by a molten area extending through the first member and the second member are provided, and the third solidified part is located closer to a non-layered surface of the second member than the second member is. Further disclosed are welding processes for producing the same.
