A current collecting lead is interposed between a sealing body and a positive electrode current collector for connecting the sealing body and the positive electrode current collector, the sealing body including a positive electrode terminal, the positive electrode current collector being attached to an electrode group, the current collecting lead including: a top wall portion positioned on the side of the sealing body; leg portions positioned on the side of the positive electrode current collector and that face the top wall portion; and a pair of side wall portions that extend between side edges of the top wall portion and side edges of the leg portions and that face each other, a first corner portion and a second corner portion formed by the top wall portion and the side wall portions and a third corner portion and a fourth corner portion formed by the leg portions and the side wall portions being rounded corners that are curved.

Current collecting lead and production method for secondary battery including current collecting lead

A nickel-hydrogen secondary battery includes: an outer can; a sealing body including a positive electrode terminal, the sealing body sealing an opening of the outer can; an electrode group formed by placing a positive electrode and a negative electrode on top of each other with a separator therebetween and spirally winding the positive electrode and the negative electrode, the electrode group housed in the outer can along with an alkaline electrolyte; a positive electrode current collector connected to positive electrode connection edge portion protruding from one end surface of the electrode group; and a current collecting lead connecting the positive electrode current collector and the sealing body, wherein a relationship between a deformation resistance A of a material a and a deformation resistance B of a material b satisfies a relationship of A&#x3c;B, wherein the material a is a material of the current collecting lead, and the material b is a material of the positive electrode current collector.
