ていた。2. Description of the Related Art In recent years, for the purpose of improving the productivity of a lead storage battery, an expanding process in which a lead alloy sheet is expanded to form slits continuously has been widely used as a method of manufacturing a lattice body. The expanding method is roughly classified into a reciprocating method and a rotary method according to the slit forming method. In the case of the reciprocating method, it is difficult to achieve both the improvement of the production speed and the miniaturization of the grids, and the use of the rotary method to achieve both the improvement of the productivity and the miniaturization of the grids is increasing. Was. However, when the above-mentioned rotary expanded lattice body is used as the positive electrode lattice, it is possible to cut at the node between the lattice mesh part and the upper and lower frame bones during the expansion processing, or to generate cracks or stress at the node. Corrosion has caused a reduction in the life of the lead storage battery.

According to the present invention, it is possible to achieve both the effect of suppressing the occurrence of cutting and cracking at the knot portion and the excellent productivity by the rotary expanding method.

ラックや切断が発生する。In any of the lattices (H to N) according to the conventional reciprocating expansion method, no cutting or cracking was observed at the knot portion, but the productivity was significantly lower than that of the rotary expanding method. In the reciprocating expansion method, since the lattice bones are sequentially developed, the magnitude relationship depending on the position of the width of the nodal portion does not directly affect the cutting or cracking of the nodal portion during the deployment. However, the development of the lead alloy sheet in the width direction in the rotary expanding method described above is performed at a time when all the joints are formed, so that cracks and cuts occur due to the relationship of the width dimensions of the joints.

Here, when the Sn content in the lead alloy sheet is lower than 0.6 wt%, the elongation of the lead alloy sheet itself increases and the strength decreases, so that even in the case of the comparative example, the cut / crack of the knot portion occurs.
