摘要: A terminal component includes a first metal and a second metal overlapped on the first metal. At a boundary between the first metal and the second metal, there is a joint portion in which the first metal and the second metal are joined by metal joining. The second metal has a groove on the outside of the joint portion on the surface opposite to the surface overlapped on the first metal.

摘要: A lithium-ion rechargeable battery includes a current collector terminal and a negative terminal unit connected to the current collector terminal. The negative terminal unit is configured to conduct electricity from an inside to an outside of a battery case. The negative terminal unit is formed of copper (Cu) or its alloy and includes a fixing member fixing the battery case to the current collector terminal. The battery is manufactured by ultrasonically bonding an external terminal formed of aluminum (Al) or its alloy to the top of a negative fixing member, fitting a busbar to a negative external terminal, and laser-welding the busbar to the negative external terminal and using the welding heat to heat the external terminal that has undergone the ultrasonic bonding to form a diffusion-bonded portion and an intermolecular-bonded portion in a bonded surface of the external terminal and the negative fixing member. Thus, conductivity is increased.
