The structure of the spiral electrode battery described above is a structure applied to batteries as large as a single type battery. This structure cannot be applied to small batteries with a diameter and height of, for example, iomm<leap. The first reason is that the beading portion 1a is formed near the open end of the anode 1 as a seat for tightening the sealing gasket 4. This beading portion 1a creates a large wasted space in the upper part of the battery case, so it cannot be applied to small batteries that require high-density packing.

(1) A cylindrical metal inner can with a bottom and a sealed surface formed by bending the upper edge inward, and an outer metal can with a bottom and a cylindrical shape that tightly accommodates the inner can. and a plate-shaped metal terminal plate that closes the opening of the outer can, and a plate-shaped metal terminal plate that is attached to the periphery of the terminal plate and is placed on the surface of the sealed opening to inwardly close the opening edge of the outer can. The battery case is made up of an annular sealing gasket that is compressed by tightening the gasket, and the power generation element is formed by alternately stacking a strip-shaped positive electrode, separator, and negative electrode and winding them in a spiral shape. A spiral electrode type battery loaded into the inner can through a spiral electrode, wherein a tip of a lead plate connected to one of the negative electrode or the positive electrode is welded to the inner surface of the terminal plate, and the other of the negative electrode or the positive electrode is welded to the inner surface of the terminal plate. A lead plate connected to the inner can is pulled out to the outside of the bottom of the inner can through a hole formed in the insulating plate and the bottom of the inner can, and a tip thereof is welded to the bottom of the inner can. Spiral electrode type battery.
