Description of the Related Art Conventional lead-acid batteries generally have an unwelded electrode plate group 4 by stacking a separator 3 between an anode plate 1 and a cathode plate 2, and weld the ears 5 of the anode plate 1 and the cathode plate 2, respectively. A current collecting section 6 is formed.

夫がなされている。Place for forming such a current collecting part 6: n-? In the just-on-strap welding method, as described above, the required number of unwelded electrode plates 4 are inverted, the ears 5 are accommodated in the mold 7, and lead or lead is injected into the mold 7. Molten lead made of alloy8
In this method, the ear portion 5 is melted and the current collecting portion 6 is formed by injecting the liquid, and the ear portion 5 is indirectly heated and welded. In this case, heat is transmitted from the ear portion 5 to the separator 3, causing cracking (thermal damage) of the separator 3. Further, the above method is essentially similar to the so-called soldering method, and the state of joining (welding) between the ear portion 5 and the molten lead 8 is not very preferable. Therefore, in order to improve the bondability, by increasing the temperature of the molten lead 8 injected into the mold 7, the amount of heat in the welding part can be increased or
Efforts have been made to remove oxides by applying slack to the surface.

有していた。However, in the method of increasing the temperature of the welding part, the anode plate 1
, the amount of heat transferred from the ears 5 of the cathode plate 2 to the separator 3 increases, and for example, when a separator 3 made of polyethylene is used, cracking (thermal damage) of the separator 3 occurs,
Therefore, an electrical defect occurs in that the anode plate 1 and the cathode plate 2 are short-circuited. Furthermore, applying a large amount of flux to the ear portion 5 has the disadvantage that it adversely affects the performance of the lead-acid battery.

The purpose of this method is to improve the bondability between the ears and molten lead, and to prevent cracking of the separator, by bringing the heat transfer body into contact with the ears when welding the current collector.
