いという欠点があつた。Prior Art and its Problems Conventionally, in a method of manufacturing a lead-acid battery in which a lead-antimony alloy inter-cell connection pole is welded by extrusion electric resistance through a through hole provided in a partition wall in a battery case, The thickness was usually set at 1.0-1.2mm. In addition, in recent years, intercell connection pole columns formed of lead alloys that do not contain antimony (hereinafter referred to as antimony-free lead alloys), such as lead-calcium alloys, have come to be used instead of the lead-antimony alloys. However, antimony-free lead alloy has a higher melting point than lead-antimony alloy, and it is necessary to weld at a considerably high temperature when extrusion-type electric resistance welding is performed on the inter-cell connection pole.
There was a drawback that the connecting pole column and the partition wall near the through hole were melted, and as shown in FIG. 5, the melted partition wall 6 penetrated into the intercell connection part 7, making it impossible to secure a sufficient welding area.

を特徴とする鉛蓄電池の製造方法である。Structure of the Invention The present invention provides a method for manufacturing a lead-acid battery in which an inter-cell connection pole made of antimony-free lead alloy is welded by extrusion electric resistance through a through-hole provided in a partition wall in a battery case. The method for manufacturing a lead-acid battery is characterized in that the partition wall has a thickness of 1.5 mm or more at a portion where the connection poles come in contact with each other.

First, as shown in FIG. 1, an intercell connection pole 3 made of antimony-free lead alloy is placed so as to cover the through hole 2 provided in the partition wall 1 in the polyolefin synthetic resin battery case.
Place a and 3b. Here, at least the part of the partition wall 1 in contact with the inter-cell connection pole pillars 3a and 3b
The thickness A is set to 1.5 mm or more. In addition,
As shown in Figure 3, the thickness of partition wall 1 is all 1.5mm.
It may be set to a value higher than that. Next, extrusion electrodes 4a, 4b
After extruding the cell-to-cell connection poles 3a and 3b using the
As shown in FIG. 4, the inter-cell connection portion 5 is completed.

As is clear from the figure, the thickness of the partition wall 1 is If the thickness is less than 1.5mm, the fifth
As shown in the figure, the partition wall 6 melted at the inter-cell connection part 7
It can be seen that the welding area is significantly reduced by penetrating the welding area. Therefore, the thickness of the partition wall 1 must be set to 1.5 mm or more.

得られる。Effects of the Invention The present invention provides a method for manufacturing a lead-acid battery in which an inter-cell connection pole column made of antimony-free lead alloy is extrusion type electric resistance welded through a through-hole provided in a partition wall in a battery case. Since the thickness of the partition wall at the portion where the pole columns contact is set to 1.5 mm or more, the heat resistance of the partition wall near the through hole is increased, and the partition wall does not melt and invade the inter-cell connection portion. Therefore, a sufficient welding area for the inter-cell connections can be secured. Furthermore, since the inter-cell connection poles are in reliable contact with the partition walls, an inter-cell connection portion with excellent liquid tightness can be obtained.
