外装体２にかえて用いる提案がいくつかなされている。Conventional technology As a measure to make storage batteries thinner, the monoblock case molded from synthetic resin such as MuBS resin has been replaced by a thermoplastic composite case in the form of a film or sheet as shown in Figure 3. Several proposals have been made to replace the bag-like exterior body 2 made of resin, for example polyethylene 1.

状外装体２の上部開口部２ｂ。In this case, the electrode plate group 7, which is made up of a positive electrode plate 4 having a resin-coated pole post 3 welded to it, a negative pole plate 6 having a pole post 3' welded to it, and a separator 6, is acid-resistant and heat-weldable. The upper opening 2b of the bag-like exterior body 2 is inserted into the interior through the bottom opening 2a of the bag-like exterior body 2 made of a film-like or sheet-like synthetic resin.

Seal 1L by heat welding. After sealing, a predetermined amount of electrolyte was injected through the opening 2e of the unwelded convex portion 2d, which served as a safety valve of the bag-like exterior body, to form a battery. However, since the material of the exterior body is film-like or sheet-like synthetic resin,
It was easily deformed and had no self-retention properties as an exterior body.

ー１３とを超音波溶着により固定していた。In recent years, in sealed lead-acid batteries, instead of the type using a gel electrolyte, a retainer type in which a liquid electrolyte is held in a mat-like separator made of glass fiber or the like has been increasingly used. However, since these separators have elasticity, there is a problem that the capacity cannot be fully extracted unless a certain pressure is applied.For this reason, as shown in Figure 4, separators made of synthetic resin such as ABS resin are used. A plurality of single cells 8 are housed in a dish-shaped case 11 having a welded edge 10 with electrical connections 9,9' to each other, and covered with a cover 13 to which input/output terminals 12 are attached. were fixed by ultrasonic welding.

問題点があった。Problems to be Solved by the Invention However, in such a structure, the case and cover are made of synthetic resin, so if the design is designed to have enough strength to apply sufficient group pressure to the housed cells, the case and cover will be damaged. There was a problem in that the thickness of the cover became thick and the size of the battery also increased, making it unsuitable for miniaturization and thinning.

Frames 15 and 15' made of BS resin are each split into two halves, and case 1 is made of aluminum plate.
4 and 14', and the cases are fixed to each other by spot welding. Next, the ABS resin frames 15 and 15' with the input/output terminals 12 attached to the terminal draw-out portions are fixed together by ultrasonic welding to form a battery. Reference numeral 16 denotes a liquid-absorbing mat for absorbing the electrolyte leaking together with the gas, which is placed above the safety valve consisting of a convex portion.

る。The height of the case 14゜14' made of an aluminum plate here does not reach the terminal part of the single cell 8, and the depth of the recess can be adjusted depending on the number of single cells accommodated inside. It is something. The one shown in Figure 1 is a single cell 8
Case 14.14 connects three of them in series.
The depth of the recesses is maintained at a level that can accommodate a total of three single cells. FIG. 2 shows a state in which frames 15 and 15' are arranged on the outside of the case, and the frames are welded together by ultrasonic welding. The state shown in Figure 2 is that the case housing the single cell inside is made of a combination of aluminum plate and synthetic resin. In addition to being able to reduce the size of the case, the thickness of the plate material can be made thinner and the weight can be reduced if the same level as a case made only of synthetic resin is maintained.

だめ放熱効果を高めることができる。(Leave below) From these results, it is clear that the product of the present invention can reduce the total thickness of the battery.In addition, the case is lined with electrical insulation for the terminal connection part of the inner single cell or the lead-out part of the input/output terminal. If it can be made of resin or the like, the whole can be made of metal, and in that case, it can be made even thinner.0 Effects of the Invention As described above, in the present invention, the inner thickness of the case part can be made thinner than before. It is possible to make the battery thinner, as well as to make the battery thinner.
By using metal as the case material, even if the battery generates heat during rapid charging, the heat dissipation effect can be enhanced because metal has better thermal conductivity than synthetic resin.
さらに金属の融点は樹脂のそれよりも高いため、例えば
８０〜１００°Ｃの高温下でも電池の変形が生じなくで
きる。Furthermore, since the melting point of metal is higher than that of resin, the battery can be made without deformation even at high temperatures of, for example, 80 to 100°C.
