Adhesive must be used for polarity and sealing of terminals. This method not only requires assembly man-hours, but also takes time for the adhesive to harden, leading to an increase in manufacturing costs. Furthermore, in the conventional method, the battery case itself is quite thick, and there is a limit to how thin it can be made. Recently, sealed lead-acid batteries have been increasingly used in home appliances, such as power supplies for hand-held cleaners and VTRs, and this trend is expected to increase in the future. As batteries become larger, it is thought that, at the same time, they will naturally become smaller and thinner, with a battery capacity of about 1 Ah or less. In this case, since the conventional technology uses a battery case, it is difficult to make it thinner due to its thickness limit and manufacturing difficulties.
Even if it were possible, manufacturing costs would increase significantly and the advantages of sealed lead-acid batteries would be lost. On the other hand, even with other methods, such as integrating the battery case and the electrode plate, it is necessary to fill the pole and terminal parts with resin as in the past, which takes a lot of man-hours and effort, and increases costs.

的とする。 The present invention aims to solve the above problems, and facilitates mechanization by wrapping the electrode plate group in a synthetic resin or a composite film of metal and synthetic resin, heat welding the surrounding area, and then sandwiching the terminals. The aim is to reduce manufacturing costs by creating a structure suitable for mass production and thinning.

Become. In addition, since the terminals are inserted and fixed onto the membrane after heat welding, there is no need to connect the poles and terminals using conventional solder, or to embed the terminals using resin, which shortens the process and time and facilitates automation. In addition, since the membrane used can be a thin film, it can be made thinner than conventional hard case batteries, improving the weight and volumetric efficiency of the battery, and reducing material costs.

The thickness of the electrode plate group 4 sandwiched between the retainer 3
Wrapped with 0.1 mm vinylidene chloride/aluminum sheet/vinyl chloride three-layer composite membrane 5 and heated around the temperature.
It was heated in a heat press at 220°C for about 1 minute to heat weld and form a battery case. At this time, the pole post 6 has also completely entered the heat welded portion 7. Figure 2 shows a schematic diagram after heat welding. Next, as shown in FIG. 3, an adhesive 9 was applied to a U-shaped terminal 8 with a sharp tip, and the terminal 8 was fixed by being inserted into the pole column 6 in the heat-welded portion from above the membrane 5. At this time, not only the membrane 5 but also the lead of the pole post 6 could penetrate easily, and the electrical contact between the pole post 6 and the terminal 8 was also perfect. Also, the ambient temperature is 40℃, 50℃
We conducted an electrolyte leakage test during a storage test and a charge/discharge cycle test at an ambient temperature of 40°C and 50°C.
No liquid leakage was observed after the 55th cycle of the cycle test. In addition, regarding the injection of gas and electrolyte generated during charging, a rubber valve 10 shown in FIG. 2 is used to release the gas. Next, we measured the amount of moisture permeation of the electrolyte from the battery during discharge at ambient temperatures of 40°C and 50°C, and found that there was almost no permeation of moisture over 70 days. This is the composite membrane 5 of the example: vinylidene chloride/aluminum sheet/
This is thought to be due to the use of vinyl chloride. Battery manufactured by the manufacturing method of the present invention (hereinafter referred to as "Battery a of the present invention")
) to investigate the performance, productivity and conventional
A battery using an ABS battery case (hereinafter referred to as "conventional battery b")
). Figure 4 shows the results of 55 cycles of a 250mA full discharge test. There was no difference between the batteries a and b of the present invention and the conventional batteries, and it was found that battery a of the present invention was not inferior to the conventional battery b in terms of capacity. The lifespan is 55 cycles, but considering that there is almost no moisture permeation of the electrolyte from the battery, it is considered to be equivalent to or longer than conventional battery B. Regarding productivity, the time required for manufacturing from inserting the electrode plate group into the battery case to embedding the pole pole and terminal part in resin for conventional battery b, and the time required for manufacturing from composite membrane welding to terminal part for battery a of the present invention. We compared the time required for manufacturing until fixation.
The results are shown in FIG. As is clear from the figure, the manufacturing method of the present invention takes about 1/15th the time compared to the conventional manufacturing method. This large difference is due in particular to the curing time of the adhesive.
