In addition, the liquid-tightness between cells can be reliably maintained by the synthetic resin body 1. In particular, since the electrodes 3 and 4 are bonded to the synthetic resin body 1 by using an adhesive, the electrolyte does not enter between the electrodes and the synthetic resin body 1 and corrosion of the current collector of the electrodes is reduced on both sides. The corrosion rate is reduced to one half of the normal rate, and the service life is prolonged.

る。Reference numeral 2 denotes an adhesive made of a laminating agent applied to the surface of the electrodes 3 and 4 facing the synthetic resin body 1. The laminating agent is, for example, a two-layer coat of epoxy resin and chlorinated polypropylene or an acrylic adhesive. Become. The electrodes 3 and 4 are bonded or heat-welded to both surfaces of the synthetic resin body 1 via the laminating agent 2. Then, at least one hole is formed through the synthetic resin body 1 and the electrodes 3 and 4 using the technology of the flexible printed wiring board, and the electrodes 3 are formed through the through holes by electroless plating or reflow of cream solder. , 4 are connected. When the connection conductor 5 is formed by plating, the connection conductor 5 is formed in a cylindrical shape on the wall surface of the through-hole. Therefore, the through-hole portion left inside the through-conductor 5 is sealed with a resin, a permanent resist, or the like. Stop. In the case of solder reflow, the above-described sealing is unnecessary because the through hole is almost completely filled with solder. As described above, the electrode unit 6 as shown in FIG. 1 is formed.

高容量化も可能である。In the storage battery of this embodiment, the current collectors of the electrodes 3 and 4 are adhered or welded onto the synthetic resin body 1 and the periphery of the synthetic resin bodies 1 and 1 'are joined to make the cells liquid-tight ( (Leakage of liquid) can be achieved, so that it is not necessary to perform additional processing for liquid-tightness between cells. In addition, since the partition wall between cells is a synthetic resin body 1 unlike the bipolar type carried by the electrode, there is a possibility of corrosion or the like. Further, since the storage battery of the present invention does not use a battery case, a mold is not required, and a battery having a required voltage can be formed with the same electrode configuration. Furthermore, unlike the conventional case where the cells are simply laminated, unlike the case where the exterior wall and the exterior film of each cell are overlapped and laminated, since only one thin synthetic resin body 1 is required for each adjacent cell, That is why it is thinner than conventional products. Further, since the current collectors such as the electrodes 3 and 4 are joined to the synthetic resin body 1 serving as the partition wall, the liquid does not enter the joining side. Therefore, the corrosion of the electrode current collector does not occur on both sides but is limited to only one side,
The corrosion rate is 1/2 that of the case from both sides, and the life is extended accordingly. Further, all the electrode units 6, the separator 7, and the single-pole unit 9 are laminated to form each synthetic resin body 1,
In the case where the peripheral portion 1A of 1 ′ is joined and integrated, the battery can have a certain high capacity by appropriately increasing the pressing force to form a laminated structure.

As compared with the case where the outer body of each adjacent cell is overlapped as in the case of the simple stacking of the above, an extremely thin sealed storage battery can be obtained. In addition, there is no need for a connection member, a contact terminal portion, a connection connector portion, or the like for electrically connecting the cells to each other outside, so that the battery can be reduced in size and weight, and the energy density of the battery can be increased. be able to.
