る。(c) Problems to be solved by the invention In the former case, since the current collector has a pair of separated pieces, when welding by pressing a welding electrode on each of the pair of separated pieces, welding is difficult. Although it has the advantage of reducing the reactive current when the current collector is supplied, the separation piece deforms as shown by the broken line in Figure 1 during the supply and welding process, and the current collectors collide with each other, making handling difficult. In addition to being complicated, if the current collector is deformed, it becomes impossible to bring the current collector into good contact with the conductive edge of a predetermined electrode plate that protrudes from the end face of the electrode body during welding, and a strong adhesion force cannot be obtained. There is.

響は阻止できず溶接効率の点で問題がある。 In the latter case, since the current collector does not have a pair of separated pieces, deformation of the current collector can be suppressed, but it is difficult to press a pair of welding electrodes onto the current collector.
When fixing by repeated spot welding, the influence of reactive current cannot be prevented and there is a problem in terms of welding efficiency.

A current collector having a protruding conductive edge and a welded portion having a slit hole is brought into contact with at least one end surface, and a conductive material protruding from one end surface is formed by a pair of welding electrodes placed on the current collector. When welding the edge and the current collector, the welding current flowing between the pair of welding poles cuts the base material of the current collector existing between the slit hole and the edge of the current collector. It is something to do.

During welding in (C), the slit hole on the center line of the current collector 10 passes through the outer edge, so as in the case of the conventional current collector shown in Figure 1, reactive current is blocked and welding efficiency is increased.

計ることができる。(G) Effects of the Invention The method for manufacturing a storage battery of the present invention is characterized in that when welding the conductive edge of the electrode plate protruding from the end face of the electrode body to the current collector, the slit hole provided in the current collector and the collector are welded together. This is to cut the current collector base material that exists between the current collector outer edge and the current collector base material that exists in the current collector from the supply of the current collector to the welding process. As in the case of using the current collector shown in Figure 1, the current collector deforms during the welding process, making handling complicated and making it impossible to properly contact the current collector with the end face of the electrode body, resulting in a strong structure. This solves the problem of not being able to properly weld.
Furthermore, after cutting the current collector base material, it is possible to prevent reactive current from flowing between the pair of welding poles, thereby improving welding efficiency.

果を奏する。 Furthermore, if a large number of protrusions forming welded parts with the conductive edges of the electrode plate are formed on the current collecting part, the current collector can be more firmly fixed to the end face of the electrode body, resulting in a further effect.
