Batteries with a 12v cell specification are most widely used. However, recently, due to the purpose of U-quantization of automobiles, 24V, 4SV
Demand for high-voltage batteries such as these is rapidly increasing. Although the number of cells in this type of high-voltage battery increases, the capacity of a single cell can be lowered. However, in all of the above-mentioned methods for connecting cells, the number of connection points increases significantly, resulting in an increase in weight, materials, and man-hours, resulting in an increase in costs.

。Function: Due to the above structure of the lead-acid battery of the present invention, electrical connections between cells can be formed by simply inserting the electrode plate current collector ears into the comb.
This is done through a conductive part that is pre-installed on the comb. Here, the mechanical strength necessary for connection between the cells can be ensured by the synthetic resin part of the comb, so the lead and lead alloy that are the conductive parts need only have the minimum cross-sectional area necessary for conduction. Therefore, overall, the amount of lead is small, it is lightweight, and it is low cost.
しかも作業性よくセル間接続を行なうことができる。Moreover, inter-cell connections can be made with good workability.

Further, as shown in FIG. 2, the cell 4 has a bag 6 made of a film-like synthetic resin as an exterior body.

A current collecting lug 9 protrudes from each cell. Insert the current collecting ears 9 into the combs 2 and 2'. A conductive portion 10 made of lead is formed between cells 1' and 1' in the comb 2, and between cells 1' and 1' in the comb 2', so that an electrical series connection between the cells is formed.

機械的接続は完成するが、さらに信頼性を高めるために
挿入後集電耳上部を弱い炎で溶融、融合させても良い。By making the current collecting ears 9 and the insertion portions of the combs 2 and 2' approximately the same width, the electrical current between the cells can be reduced just by inserting the current collecting ears 9.
The mechanical connection is completed, but to further improve reliability, the upper part of the current collecting ear may be melted and fused with a weak flame after insertion.

法以上に高めることができる。Further, although only three cells are shown in FIG. 1, it is easy to make a pair of combs into which the current collecting ears of all the cells forming the battery can be inserted. At this time, by making the pair of combs from thermoplastic resin, it is easy to thermally weld them to the battery case or lid. With this configuration, the connection between the cells can be integrated with the battery case or the lid, and the mechanical strength can be increased more than the conventional connection method between cells.
