う問題があった。[Problems to be Solved by the Invention] However, there is a problem in that the electrode 12 of the conventional electrode unit 34 is caused by a halogen substance, and in the metal-bromine battery, warpage (distortion due to elongation) is caused by bromine.

ト３４の外枠３４ａのプラスチック板においてはあまり
問題とはならない。That is, as described above, the electrode 12 is extruded from lightweight and low-cost carbon plastic, but this carbon plastic plate absorbs bromine and stretches. This is due to the fact that the carbon plastic snack plate particularly contains carbon, and does not pose much of a problem with the plastic plate of the outer frame 34a of the electrode unit 34.

することにより、押出し方向の臭素による伸びを大幅に
低減することができる。Therefore, conventionally, in order to improve warpage resistance (bromine resistance), a reinforcing material such as carbon fiber is mixed in during the kneading process of carbon and plastic. By extrusion molding carbon plastic mixed with a reinforcing material, elongation due to bromine in the extrusion direction can be significantly reduced.
しかしながら、前記伸びの低減は押出し方向においては
良好に改善されるが、押出し方向と垂直の方向では改善
が不十分であるという聞届があった。これは、補強材で
ある前記カーボンファイバが押出し方向に並ぶように配
列し、方向性が生じるからである。However, it has been reported that although the reduction in elongation is well improved in the extrusion direction, the improvement is insufficient in the direction perpendicular to the extrusion direction. This is because the carbon fibers serving as reinforcing materials are arranged in the extrusion direction, resulting in directionality.
このようなことから、従来では補強材としてグラファイ

性を生じさせることなく耐ワーペイジ性を改善すること
ができる。For this reason, conventionally, graphite has been blended as a reinforcing material, and this makes it possible to improve warpage resistance without causing directionality.
しかし、前記グラファイトは臭素と反応して電池性能を
悪化させる傾向があるため、グラファイトの配合量には
限界があり、これによっても前記押出し方向に垂直な方
向のワーペイジを完全になくすことができなかった。However, since graphite tends to react with bromine and deteriorate battery performance, there is a limit to the amount of graphite that can be added, and even with this, it is not possible to completely eliminate warpage in the direction perpendicular to the extrusion direction.

The thickness of the electrode plate 12 can be about 0.5vn.
The thickness is approximately 11. Although it is desirable that the thickness of the carbon plastic plate 44 be the same, it can be set arbitrarily.

However, the invention is not limited to this, and the number of sheets may be three or four. For example, in the case of three sheets, it is also preferable to overlap them so that the extrusion directions intersect at 30 degrees. In this way, the present invention has the advantage that the thickness of the electrode plate 46 can be arbitrarily set by selecting the number of stacked carbon plastic plates 44.
