があつた。D Problems to be Solved by the Invention The conventional end plate electrode configured in this manner has the following problems:
Because sufficient bonding strength could not be obtained between the metal net and the carbon plastic, both had to be held together by an insulating frame, which was two to three times thicker than the intermediate electrode. Various problems arose.

積層電池組立の際に修正が困難であり、取扱が

る。E Means for Solving the Problems The end plate electrode for a laminated battery according to the present invention includes a conductive plastic electrode plate which is a rectangular electrode plate, and an electrode terminal buried in contact with the conductive plastic electrode. A laminated battery in which an insulating frame is provided around one surface of an electrode plate by combining a metal net and an insulating frame made of synthetic resin to form a battery reaction chamber surrounded by an insulating frame on the electrode plate surface. In the end plate electrode for use, at least an edge portion sandwiching the metal net has a superposed structure of the conductive plastic electrode plate and a frame material plastic plate made of the same material as the insulating frame, and the opposite side sandwiching the metal net An electrode material plastic plate made of the same material as the conductive plastic electrode plate is placed on the side over the entire surface excluding at least the edge portion, and is integrated under pressure.

する。F Function The end plate electrode of the present invention has a structure in which a conductive plastic electrode plate and a frame material plastic plate made of the same material as the insulating frame are overlaid, with at least the edge portion sandwiching the metal net, and the metal net is sandwiched between the conductive plastic electrode plate and the insulating frame. Since the electrode material plastic plate made of the same material as the conductive plastic electrode plate is arranged on the opposite side over the entire surface excluding at least the edge portion, when the frame material plastic plate is integrated under pressure, the frame material plastic plate is made of the mesh of the metal net. It is fused with conductive plastic through.
このような重ね合せ構成とすることによつて、
金属ネツトと電導性プラスチツク板との間の結合

This strengthens the bond between the metal net and the conductive plastic plate.

ラスチツク板が金属ネツトを挾んで融着するが、
金属ネツトと導電性プラスチツク板との間の電気
導電性は何んら阻害されない。 This is because conductive plastic sheets become considerably soft during molding, but because they are not dynamic in nature, conductive plastic sheets are difficult to fuse together, and metal nets are simply mechanically crimped together. On the other hand, the frame material plastic plate and the conductive plastic plate are effectively fused together. Note that the frame material plastic plate, which is an insulator, sandwiches the metal net and welds it together.
The electrical conductivity between the metal net and the conductive plastic plate is not disturbed in any way.

このため端板電極の反りを大幅に抑制する。 Furthermore, in order to have a configuration in which a plastic plate for the electrode material made of the same material as the conductive plastic electrode plate is arranged on the opposite side of the metal net over at least the entire surface excluding the edge portion, the plastic plate for the electrode material is made of a conductive material. It expands and contracts like a plastic board.
Therefore, warping of the end plate electrodes is greatly suppressed.

The plastic plates 14b, 14d, and 14f are made of the same material as the outer frame molding plastic 14c.

導電性は何んら阻害されない。 One feature of the end plate electrode according to the present invention is that the plastic plate 14f is fused to the carbon plastic 14a through the mesh of the metal net 15, and such a superimposed structure is adopted. One of the structural features is that the metal net 15 and the carbon plastic 14a are fused together, thereby strengthening the bond between the metal net 15 and the carbon plastic 14a. This is because the carbon plastic 14a becomes considerably soft during molding, but since it is not dynamic in nature, it is difficult for carbon plastics to be fused together, and the metal net 15 is only mechanically crimped. On the other hand, the plastic plate 14f and the carbon plastic 14a are effectively fused together. Although the plastic plate 14f, which is an insulator, sandwiches and fuses the metal net 15, the electrical conductivity between the metal net 15 and the carbon plastic 14a is not inhibited in any way.

る。 Further, the carbon plastic 14e is covered with plastic plates 14b and 1 which are insulators from both sides.
Since carbon plastic 14f is fused, it does not function as a conductive material, but carbon plastic 14e expands and contracts in the same way as carbon plastic 14a. Therefore, warpage of the end plate electrode can be significantly suppressed.

べて薄くなつている。 These overlapping configurations reduce the amount of frame material (frame material has a high shrinkage rate) and the non-flowing properties of carbon plastic reduce frame material flow during compression molding and reduce post-molding warpage. It has a suppressive effect. Further, the outermost plastic plate 14b is made of the same material as the frame 14c, and serves to improve the warping condition and to make the non-liquid-contact side surface an insulating surface. In addition, in FIG. 5, if the thickness of each member is expressed as shown, they have the following thickness relationship, and the thickness of the end plate electrode after molding is the same as that of the conventional one. It is thinner than .

Effects of the Invention As explained above, the present invention has a structure in which the conductive plastic electrode plate and the frame material plastic plate made of the same material as the insulating frame are stacked with at least the edge portion sandwiching the metal net, and the metal net is On the opposite side of the sandwich, a plastic plate made of the same material as the conductive plastic electrode plate was placed over the entire surface except for at least the edges, and was integrated under pressure, so that the gap between the metal net and the conductive plastic plate was In addition to making the connection stronger, the plastic plate of the electrode material is placed on the opposite side of the metal net, so there is less warping after molding or during use, and the thickness of the end plate electrode can be reduced. This has the effect of making it possible to realize the following.
