のである。[Problems to be Solved by the Invention] A connecting body using a lead/antimony alloy melts with the calcium alloy in the negative electrode lattice when forming the negative electrode side, and forms an intermetallic compound of antimony and calcium, such as Sb3Ca. This intermetallic compound is highly corrosive, and when left in a high temperature or weakly acidic oxygen atmosphere, the problem is that dissolution and corrosion progress, leading to wire breakage. The present invention is directed to a lead-acid battery with a so-called hybrid configuration in which a lead-antimony alloy is used for the positive electrode grid and a calcium alloy is used for the negative electrode grid, as described above, in which the grid and strap parts or the straps are damaged due to corrosion or melting of the negative electrode side connector. It is an object of the present invention to provide a lead-acid battery having a hybrid structure, which has a negative electrode side connecting body that prevents disconnection between parts and connecting parts, has high mechanical strength, and is not disconnected due to vibration or the like.

充分耐える性能も有している。[Operation] Since the positive electrode plate is made of a lead-antimony alloy, the positive electrode connector is formed using an alloy of the same quality as the lead-antimony alloy for both the connecting part and the strap part. Since the same alloy is used, weldability is good, and corrosive intermetallic compounds do not occur between the alloys of the grid and the strap part, and the strap part and the connection part, so it can be used at high temperatures or in weakly acidic or neutral oxygen atmospheres. Even if exposed, corrosion or dissolution will accumulate only on the surface, and it will take time for the center to be eroded. Therefore, the function can be fully satisfied without disconnection during the life of the lead-acid battery. Furthermore, since the strap part is made of a lead/antimony alloy, it has great mechanical strength and has the ability to withstand equipment that is subject to strong vibrations.

A lead-antimony alloy is used for the connection part of this connection body in consideration of connectivity between cells, but a non-antimony, non-calcium lead alloy is used for the strap part. Even if the lead/calcium alloy of the lattice and the non-antimony/non-calcium lead alloy of the strap part of the negative electrode connector are melted, no intermetallic compound of antimony and calcium is formed, so the strap part has high corrosion resistance and can be used under various conditions. The wire will not break due to corrosion or melting. Further, the connecting portion of the negative electrode connector is made of a lead/antimony alloy, and the strap portion is made of a non-antimony/non-calcium lead alloy, so that the intermetallic compound is not generated in the molten portion as well. The non-antimony/non-calcium lead alloy of the negative electrode connector strap contains 0 tin.
．． A lead alloy containing 5 to 5% is preferred, but it is also preferable to include a small amount of aluminum, silver, arsenic, copper, bismuth, etc., as this is effective for improving mechanical strength and corrosion resistance. Also, the connection parts of the positive electrode connector and negative electrode connector
The antimony alloy can contain small amounts of silver, arsenic, copper, bismuth, tin, etc. according to conventional methods.

The partition walls are arranged to face each other, and the two are fused and joined by resistance connection or pressure welding at the partition through-hole to complete the connection between the cells. This connection part is made of lead/antimony alloy for both the positive electrode connection body and the negative electrode connection body, and does not generate intermetallic compounds.

りにくく、実使用中に断線に至ることはない。Next, a method for manufacturing the present lead-acid battery will be explained with reference to FIG. First, on the positive electrode side, a positive electrode plate 6 using a grid made of a lead-antimony alloy is connected to the positive electrode connector strap part 9 by the COS method. That is, by injecting molten lead/antimony alloy into the positive electrode side mold from the sprue, the positive electrode connector strap portion 9 and the positive electrode connector connecting portion 1 are separated.
0 at the same time, and before the molten metal solidifies, the lug of the positive electrode plate 6 is inserted into the positive electrode side mold to connect the positive electrode plate 6 and the positive electrode connector strap part 9. Therefore, the positive electrode grid 6
, the positive electrode connector strap portion 9, and the positive electrode connector connecting portion 10 are made of the same lead-antimony alloy. Since the three parts are made of the same material, corrosion or dissolution is unlikely to occur even in high-temperature, weakly acidic or neutral oxygen atmospheres, and wire breakage will not occur during actual use.

。On the other hand, on the negative electrode side, a negative electrode plate 7 using a lead-calcium alloy grid is connected to the negative electrode connector strap portion 11 by a method similar to the COS method. That is, a molten metal of non-antimony, non-calcium lead alloy is poured into the negative mold I through a sprue, and until the molten metal solidifies, the lug of the negative plate 7 is inserted into the negative mold, and the negative plate 7 and the negative connector strap are inserted. Connect section 11. Next, in order to form the negative electrode connector connecting part 12, the negative electrode side mold II is brought into contact with the negative electrode connector strap part 11, and molten lead/antimony alloy is poured into the negative electrode side mold II from the sprue, thereby forming the negative electrode connector. A connecting portion 12 is formed and connected to the negative electrode connector strap portion 11 . Therefore, the negative electrode connector strap part 1
1 may be mixed with calcium in the negative electrode grid 7, but antimony contained in the negative electrode connection body connection part 12 will not be mixed with the conventional COS as shown in FIG.
Since an intermetallic compound consisting of antimony and calcium, which is produced in the method, is not produced, it is possible to form the negative electrode connector strap portion 11 having corrosion resistance and dissolution resistance.

The positive electrode connector connecting portion 10 and the negative electrode connector connecting portion 12 are connected using welding, pressure welding, or the like. In addition, since both the positive and negative polarity connection parts are made of a lead-antimony alloy, the joint part 13 can be constructed with excellent corrosion resistance and melting resistance.

。Note that in the above method, the negative electrode connector strap portion 11 is formed first, but in contrast, the negative electrode connector strap portion 11 is formed first.
2 is formed first, and then the negative electrode connecting body strap part 11 is formed.
The formation of the negative electrode connecting body connecting part 12 and the connection with the negative electrode connecting body connecting part 12 may be performed at the same time. Furthermore, the negative electrode connecting body connecting part 12 is cast in advance and inserted into the negative electrode side mold II to form the negative electrode connecting body strap part 11. Further, the connection with the negative electrode connector connecting portion 12 may be made simultaneously. Furthermore, if the alloys of the positive and negative electrode grids are opposite to those described above, it goes without saying that the positive and negative polarity connectors are also formed by the method opposite to that described above.

The lead-acid battery A had no abnormality in the vertical strap connecting both poles even after the expected life had passed, but the lead-acid battery B had reached the end of its life before the expected life. When we investigated the cause, we found that the wire broke due to corrosion in the negative electrode connector strap where intermetallic compounds had formed.
