CLADDING MATERIAL FOR LEADS AND METHOD OF WELDING CLADDING MATERIAL FOR LEADS
First Claim
1. A cladding material (1) for a lead welded to a terminal (21, 22) of a battery (2), comprising:
- a first Ni layer (11) arranged on a side welded to the terminal of said battery;
a second Ni layer (12) arranged on a side opposite to said welded side; and
an Fe layer (10) arranged to be held between said first Ni layer and said second Ni layer, whereinthe thickness of said first Ni layer is at least 2.1% and not more than 8.2% of the thickness of said cladding material consisting of said first Ni layer, said second Ni layer and said Fe layer.

Abstract
A cladding material for a lead capable of inhibiting foreign matter from remaining on a surface can be obtained. The cladding material (1) is a cladding material for a lead welded to a terminal (21, 22) of a battery (2) and comprises a first Ni layer (11) arranged on a side welded to the terminal of said battery, a second Ni layer (12) arranged on a side opposite to said welded side and an Fe layer (10) arranged to be held between said first Ni layer and said second Ni layer. The thickness of the first Ni layer is at least 2.1% and not more than 8.2% of the thickness of said cladding material consisting of the first Ni layer, the second Ni layer and the Fe layer.

7. A method of welding a cladding material for a lead by resistance-welding a cladding material (1) including a first Ni layer (11), a second Ni layer (12) and an Fe layer (10) arranged to be held between said first Ni layer and said second Ni layer, wherein the thickness of said first Ni layer is at least 2.1% and not more than 8.2% of the thickness of said cladding material consisting of said first Ni layer, said second Ni layer and said Fe layer, to a terminal (21, 22) of a battery (2), comprising the steps of:
-
arranging said cladding material on the terminal of said battery so that said first Ni layer is positioned on the side of the terminal of said battery; and resistance-welding said first Ni layer to the terminal of said battery by feeding electricity to an electrode (4a) for resistance welding in a state of arranging the electrode on the side of said second Ni layer opposite to the side where the terminal of said battery is positioned. - View Dependent Claims (8)
