ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a diaphragm supporter for batteries (e.g. zinc-bromine batteries). For more details,
The present invention relates to a diaphragm supporter for supporting and protecting a diaphragm (for example, a porous membrane or an ion exchange membrane) that is a means of isolating an anode chamber and a cathode chamber in a stacked battery.

般的に行なわれていた。 In conventionally used stacked batteries, if the diaphragm does not have a supporter, the diaphragm swells due to liquid circulation during battery operation, contacts the electrode surface, and the electrolyte stops flowing on the contact surface, causing the electrode to swell. Not only does it no longer function as an electrode, but the effective area becomes smaller than the initial electrode area, and the current is concentrated in that area, which also affects the electrodeposition of zinc, causing a significant decrease in battery efficiency. Therefore, conventional methods for reinforcing the mechanical strength of the diaphragm include (i) increasing the mechanical strength of the membrane itself;
Generally, either (ii) inserting a supporter on both sides of the diaphragm to protect the diaphragm from both sides, or (iii) using a combination of (i) and (ii) above.

があつた。 Here, when using a supporter to reinforce mechanical strength, a mesh made of polyethylene or the like is used as the supporter, but because it comes into direct contact with the electrode, the electrode area cannot be effectively utilized on the cathode side. However, there was a problem in that the electrodeposition of zinc also became mesh-like and non-uniform, which affected battery efficiency.

This supporter is made of, for example, polyolefin, generally polyethylene or polypropylene, and has a mesh and a plurality of protrusions 41 and 42 formed by integral molding. The protrusion 41 provided on the side facing the electrode has a tapered, rounded or sharply pointed tip.
Further, it is desirable that the height h 1 of each protrusion 41 is the same, and if possible, the tolerance thereof is less than h 1 ±0.2 mm. Further, the tips of the protrusions 42 provided on the side facing the diaphragm 4 are formed into round heads as shown in the figure, and it is desirable that the heights h 2 of the protrusions 42 are all the same. The shape of the mesh itself may be square, round, or triangular. In addition, it is desirable that the number of meshes is 7 or more, and the number, spacing, and height of the protrusions 41 and 42 are
h 1 and h 2 can be set arbitrarily depending on the size of the diaphragm, the conditions of use, etc.

配はない。 In this way, the supporter is composed of a mesh board,
When a plurality of protrusions 41 and a plurality of protrusions 42 are provided on both sides of the mesh plate facing the electrode and the diaphragm, the tips of the protrusions 41 and 42 are formed on the electrode surface and the diaphragm surface, as shown in FIG. There will be point contact with each other. For this reason, if the diaphragm 4 is sandwiched and stacked between the supports 4A and 4B so that the protrusion 42 with a rounded tip faces the diaphragm 4 and the protrusion 41 faces the electrode, the supports 4A and 4B The loss of electrode area caused by this can be considerably reduced, and problems such as dendrites can also be reduced, and furthermore, the distance between the diaphragm 4 and each electrode 5, 6 can be maintained almost uniformly over the entire surface by the projections 41, 42. As a result, the electrolyte can be circulated efficiently. Moreover, the diaphragm 4 is
The protrusion 42 formed with a round head makes point contact with the anode electrode,
Since the cathode electrodes are pressed against each other from both sides, the opening area of the mesh can be increased, and the mechanical strength can also be increased, effectively preventing deformation of the diaphragm 4 itself due to stagnation, swelling, etc. In addition, since the tip of the protrusion 42 is formed into a round head as described above, there is no fear of damaging the diaphragm 4.
