摘要： A battery terminal is made of a clad material in which a first metal layer made of an Al-based alloy, a second metal layer made of a Cu-based alloy, and a third metal layer made of a Ni-based alloy are bonded to each other in a state where the first metal layer, the second metal layer, and the third metal layer are stacked in this order. The battery terminal includes a shaft portion and a flange portion that radially expands from the shaft portion, and has the third metal layer at least in an end of the shaft portion on a first side in a shaft direction in which the shaft portion extends.

摘要： A battery terminal includes a shaft portion and a flange portion. The battery terminal is made of a clad material in which at least a first metal layer and a second metal layer are bonded to each other. Each of the shaft portion and the flange portion includes the first metal layer on a first side in a shaft direction and the second metal layer on a second side in the shaft direction. The first metal layer in the shaft portion includes a protruding portion that further protrudes to the second side in the shaft direction with respect to a surface of the first metal layer on the second side in the shaft direction in the flange portion.

摘要： An aluminum copper clad material has excellent bonding strength and includes an aluminum layer and a copper layer that are bonded without a nickel layer interposed therebetween. The aluminum layer and the copper layer are diffusion-bonded via an Al—Cu intermetallic compound layer. The copper layer satisfies Dcs≦0.5×Dcc, where Dcc represents the average crystal grain size of crystal grains in a central portion in the thickness direction of the copper layer, and Dcs represents the average crystal grain size of an interface adjacent portion C2 in the copper layer that is about 0.5 μm apart from the interface between the copper layer and the intermetallic compound layer. The intermetallic compound layer has an average thickness of about 0.5 μm to about 10 μm.

摘要： The present invention relates to a lithium ion battery employed by connecting the positive electrode side to a negative electrode portion made of Cu or a Cu alloy by a bus bar made of Al or an Al alloy and provides a negative electrode terminal for a lithium ion battery capable of providing sufficient bonding strength between the negative electrode portion and the bus bar when the negative electrode portion and the bus bar are metallurgically bonded to each other by resistance welding or the like, for example. This negative electrode terminal for a lithium ion battery is made of a clad material having a first metal layer made of Al or an Al alloy and a second metal layer made of Cu or a Cu alloy bonded to each other through a reaction-suppressing layer suppressing a reaction therebetween.
