Embodiment Construction

[0015] Embodiments of the present invention will be described based on the drawings. figure 1 (A) is the figure of the intermediate part of the hoop-shaped part used in the present invention, figure 1 (B) is a figure which shows an example of the hoop-shaped member for aluminum tabs concerning this invention, figure 1 (C) is a figure which shows an example of a tab.

[0016] like figure 1 As shown in (A), the ferrule-shaped member 10 used in the present invention is constituted as follows, that is, on one side or both sides of the strip-shaped flat conductor 11 made of aluminum, solder-friendly parts are formed locally at predetermined intervals. The welded metal layer 12 is wound into a hoop. As the metal layer 12, a metal having conductivity and being easy to solder, such as Ni, Sn, Au, Zn, Ag, Cu, or an alloy of the above metals, is used. Methods for forming these metal layers 12 will be described later.

[0017] figure 1 (B) is the hoop member 10' of the present inve...

Abstract

PROBLEM TO BE SOLVED: To provide a hoop-like member which can supply an aluminum tab lead provided with a solder connectable metal material only by cutting a supplied belt-like aluminum conductor at a predetermined location.SOLUTION: On a face of a belt-like flat conductor 11 made of aluminum or aluminum alloy, a metal layer 12 made of a conductive metal which is easily soldered is partly formed with a certain interval, and an insulating resin film is attached between the metal layers from both sides of the flat conductor. Ni, Sn, Au, Zn, Ag, Cu, or a combination thereof may be used as the conductive metal. Thickness of the metal layer 12 is preferably 0.5 mm or less, and the metal layer 12 can be formed by any one of partial plating, cold spray, and cold pressure welding.

Description

technical field [0001] The present invention relates to a ferrule-shaped member for a tab using an aluminum conductor used in non-aqueous electrolyte equipment and the like. Background technique [0002] As a power source of a small electronic device, for example, a nonaqueous electrolyte battery such as a lithium ion battery is used. As such a nonaqueous electrolyte battery, a structure is known in which a positive electrode plate, a negative electrode plate, and an electrolytic solution are accommodated in a package made of a multilayer film, and tabs connected to the positive electrode plate and the negative electrode plate are sealed. Lead it out. In this case, a lead material such as aluminum or an aluminum alloy is usually used for the tab on the positive electrode side. [0003] Tabs made of aluminum or an aluminum alloy cannot be easily electrically connected by soldering. Therefore, it is necessary to use special means such as welding when connecting a plurality ...
