密度が高めることができる。[Function] In the storage battery of the present invention, the partition walls between the cells are formed by one synthetic resin body 1, so that the exterior body of each adjacent cell is different from the conventional case where each cell is simply laminated. An extremely thin battery can be obtained compared to a battery that is stacked overlappingly. Furthermore, since the positive and negative electrodes of adjacent cells are electrically connected by the connecting conductor 5 penetrating the synthetic resin body 1,
Since there is no need for external wiring sections, contact terminal sections, connection connector sections, etc. for electrically connecting the cells, the battery can be made smaller and lighter, and the energy density of the battery can be increased.

１７７２に低下し、それだけ寿命が長くなる。When the present invention is applied to a liquid type battery in which the separator 7 is an electrolyte holder, the synthetic resin body 1 can reliably maintain liquid tightness between the cells. In addition, since the electrodes 3 and 4 are bonded to the synthetic resin body 1, the electrolyte does not enter the gap between the electrodes and the synthetic resin body 1, and corrosion of the current collector of the electrode does not occur on both sides. Since the corrosion rate only occurs in the normal case, the corrosion rate is reduced to 1772 times compared to the normal case, and the life span is increased accordingly.
また隔離体７を固体電解質とすると、１枚の薄い合成樹
脂体１によりセル間の気密性か中部に保たれた薄形密閉
形の固体電解質蓄電池が得られる。If the separator 7 is a solid electrolyte, a thin sealed solid electrolyte storage battery is obtained in which the single thin synthetic resin body 1 maintains the airtightness between the cells in the middle.

Electrode 3.4 is made of this laminating agent 2
It is adhered or thermally welded to both sides of the synthetic resin body 1 via. Then, using flexible printed wiring board technology, at least one hole is made through the synthetic resin body 1 and the electrodes 3 and 4, and the electrode 3 is formed by electroless plating or cream solder paste flow through the through hole. A connecting conductor 5 is provided to connect both of the two. Note that when the connecting conductor 5 is formed by plating, the connecting conductor 5 is formed in a cylindrical shape on the wall surface of the through hole, so the through hole portion left inside the through conductor 5 is sealed with resin, permanent resist, etc. Stop. In the case of solder reflow, the above-mentioned sealing is not necessary because the through hole is almost filled with solder. In the manner described above, the electrode unit 6 as shown in FIG. 1 is formed.

An electrode unit laminate is formed by sequentially stacking the electrode units with their negative electrode surfaces facing each other and interposing a separator 7 containing an electrolyte therebetween. As the separator 7, a separator or an electrolyte holder is used in a liquid type storage battery such as a sealed lead acid battery, and a solid electrolyte is used in a solid storage battery.

A negative monopolar unit 9 is arranged with a separator 7 in between. The positive and negative single-pole units 9 are each provided with a terminal 8 fixed to a positive electrode or a negative electrode, penetrating the synthetic resin body 1-. The peripheral portions IA of all the synthetic resin bodies 1.1- of the laminated structure of this battery are joined and integrated by thermal welding or the like to form the storage battery of this embodiment.

電池では合成樹脂体１によりセル間の気密性が十分に保
たれる。In the liquid 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
By joining the periphery of ', it is possible to make the cells liquid-tight (to prevent liquid leakage), so there is no need for additional processing to make the cells liquid-tight. Further, in a solid battery, the synthetic resin body 1 sufficiently maintains airtightness between cells.
そして、セル間の隔壁は、電極が担うバイポーラ方式と
異なり、合成樹脂体１なので、腐食等のおそれもない。Unlike the bipolar system in which the partition walls between the cells are formed by electrodes, the synthetic resin body 1 eliminates the risk of corrosion.

とは異なり、隣接セルごとで１枚の薄い合成樹脂体１で
済むので、それだけ従来品よりも薄形に構成される。Furthermore, since the storage battery of the present invention does not use a container, no mold is required, and batteries of the required voltage can be produced with the same electrode configuration. Furthermore, unlike conventional cell lamination, in which the exterior walls and exterior films for each cell are laminated in duplicate, only one thin synthetic resin body 1 is required for each adjacent cell. This makes it thinner than conventional products.

積層構成することにより、電池のある程度の高容量化も
可能である。Furthermore, since the current collectors such as the electrodes 3.4 are bonded to the synthetic resin body 1, which is a partition wall, in the case of a liquid type battery, liquid does not enter into this bonded side. Therefore, corrosion of the electrode current collector does not occur on both sides, but is limited to only from one side, and the corrosion rate is 1/2 of that from both sides, resulting in a correspondingly longer life. Furthermore, when all the electrode units 6, separators 7, and monopolar units 9 are stacked and the peripheral parts IA of each synthetic resin body 1, 1' are joined and fixed together, the pressing force is increased appropriately and the stacking is performed. By configuring this structure, it is possible to increase the capacity of the battery to some extent.

In addition, there is no need for wiring members, contact terminals, or connectors for external electrical connection between cells, making it possible to make the battery smaller and weigh more, increasing the energy density of the battery. be able to.
