本発明は、蓄電池、例えばニッケルーカドミウム蓄電池

池の組み立て方法を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a storage battery, such as a nickel-cadmium storage battery. This provides an assembly method.

ド線を予め溶後やかしめにより１本にまとめ、これを陽
極リード線は封口板に、また陰極リード線はケースの内
壁にそれぞれ溶接するのが普通であった。The conventional current collection method for storage batteries using spiral electrode groups is to weld one lead wire or a textbook lead wire to the electrode plate, melt the lead wires in advance, and then combine them into one wire by caulking, and connect this wire to the anode lead. It was common practice to weld the wire to the sealing plate and the cathode lead wire to the inner wall of the case.

集電板を溶接する方法もある。これらの集電方式の最大
の欠点は、電池の高率放電時における極板抵抗による電
圧降下である。There is also a method in which green edges of the electrode group are made to protrude above and below the electrode group, and a current collector plate is welded to this protruding part. The biggest drawback of these current collection systems is the voltage drop due to plate resistance during high rate discharge of the battery.

のである。During discharge, the current from the electrode plate is discharged to external equipment through the lead wire or current collector plate. At this time, since there are long and short distances between the electrode plate and the lead wire or current collector, the resistance of the electrode plate increases at extremely sloped parts other than the welded parts such as lead wires.
As the current flow worsens, the utilization of the electrode plates decreases rapidly. Furthermore, the assembly of the battery is also complicated due to the welding process of the lead wires and the force concentrator plate to the electrode group.
The present invention provides a storage battery which eliminates the disadvantages of such secondary batteries, is easy to assemble, and exhibits little voltage drop during high rate discharge.

は最低値に近似する。That is, the present invention provides a spongy metal body with a spiral electrode group in which the green end of one electrode plate protrudes from the bottom end and the green end of the other electrode plate projects from the top end, and is arranged above and below the spiral electrode group. Insert it into the loose case, tighten the sealing plate that seals the entrance of the case, press the sponge-like metal body to the electrode group, and comb the green end of the electrode plate into the sponge-like metal body to make an electrical connection. It is characterized by obtaining. According to this method, the edge of the electrode plate can be connected to the sponge-like metal body of the current collector over its entire length, so there is no difference in distance between the electrode plate and the current collector, and the The plate resistance value approximates the minimum value.
