Abstract

PURPOSE:To reduce the internal resistance of an assembly battery produced by connecting sealed alkaline batteries in series by directly welding the positive terminal of a single battery to the negative terminal of another single battery. CONSTITUTION:After a single battery 6 such as a sealed alkaline battery is positioned on a support base 5, a welding electrode 9 supported by an electrode holder 8 is brought into contact with the lid 7 of the battery 6. After the negative terminal of another single battery 6' is placed on the projection 11 of the upper lid 10 of a safety-valve installation part which is welded to the lid 7 and also serves as a positive terminal, the battery 6' is supported by a welding electrode 9' also serving as a battery holder. After that, the positive and the negative electrodes are directly welded together by feeding a current while applying a proper pressure to connect the batteries 6 and 6' together. By the means mentioned above, many single batteries can be connected into an assembly battery without using any lead plate. Consequently, it is possible to significantly reduce the internal resistance of the assembly battery and to increase its performance.

It is almost always used in the form of a so-called assembled battery. Therefore, naturally,
It is necessary to electrically connect the single cells to each other, and for this purpose, for example, method 1j as shown in FIG. 3 has been adopted. That is, the lead plate 4 made of a ribbon-shaped metal connects the upper lid 2 of the safety valve storage part, which also serves as the anode terminal of the unit battery 1, and the battery can 3', which also serves as the cathode terminal of the adjacent unit battery 1'.
It was connected with. Resistance welding is used to connect the lead plate 4 and the top cover 2 or battery can 3'.

る電池を生産する場合法して無視出来るものではない。Problems to be Solved by the Invention Incidentally, as the demand for Ni-Cd batteries increases, what has recently been particularly required is an improvement in high-rate discharge performance.For example, when used in hand-held dust cleaners or power tools, etc. The battery is discharged at a current 10 to 20 times the nominal capacity of the battery.
J1% IF 'MP 4h 'RP rl: /I'
% IG Th< /l) The question is how long the discharge can be carried out. Various measures are necessary to meet such demands, and among these, one of the most important is how to reduce the internal resistance of the battery. One example is a multi-point current collection system that uses multi-tabs to collect current from a group of plates housed in a single cell. This concept of reducing the internal resistance of single cells must also be applied to assembled batteries in order to meet the above requirements. The problem at this time is how to connect the single cells to each other. The conventional method is shown in Figure 3, for example, 1200 mA.
In the case of a set of 10 SC size batteries of h, t O,L
A total of 9 Fe lead plates of 8 Xw 60X, g 25 mm will be used. Of the internal resistance of the assembled battery when it is actually made into a product, how much resistance is at the interconnection part of the cells by the lead plate as mentioned above? In the case of an SC type battery, there is a voltage drop of about 0.02V in 1OcrnA discharge (discharge with a current 10 times the nominal capacity). Therefore, it cannot be ignored when producing batteries that satisfy the requirements mentioned at the beginning.

The shorter the length, the better. The most preferable condition is to use a lead plate.
The top cover and the battery can of the adjacent battery are directly connected, and the present invention provides this type of connection technology as a means for lowering the internal resistance of the assembled battery.

Due to the warping of the four-pot eggplant, both members melt due to resistance heat generation at the contact surface between the upper cover 10 and the battery can 12 of the cell 6', and the cell 6 and the cell 6' are separated from each other as shown in FIG. Thus, the connection is made without requiring the μIJ-board 4.

For example, laser welding is one example. In this case, as shown in FIG. 2, a protrusion 13 is provided on the bottom of the battery can of the cell 6', and the contact surface between this and the top lid 10' is heated with laser beams. 14 to melt and weld. In this case, it is also necessary to connect the cells in a jig-deg arrangement as in the case of resistance welding.
Therefore, it is advantageous in terms of reducing the storage volume of the assembled battery.
