た積層型電池に関する。[Detailed description of the invention] [Industrial field of application] The present invention relates to the improvement of stacked batteries, specifically the position of the frame portions of electrode plates and diaphragms made of thermoplastic synthetic resin, and the end plates. A concave and convex portion is provided on the peripheral portion that can be combined in one direction, and sealing properties are provided by elastic deformation of the frame member that occurs on the contact surface of the concave and convex portion due to the tightening force during battery assembly. This invention relates to a compact stacked battery with a structure that eliminates the need for conventional packing.

The electrode plates and diaphragms used in conventional stacked batteries have a central electrode surface portion 5 as shown in FIGS.
Alternatively, the electrode frame portion 1 or the diaphragm frame portion 2 was provided around the diaphragm surface portion 6, protruding from the surface portions 5 and 6 in the direction of both surfaces, respectively. When constructing a battery, as shown in FIGS. 7 and 8, electrode plates and diaphragms are alternately stacked between the end plates 3 at both ends, and between the electrode plates and the diaphragms and between the electrode plates and the ends. Packing 4 was inserted between each plate to provide sealing properties, and the entire structure was tightened with tightening bolts and nuts. The space 7 of the battery configured in this way becomes a circulation path for the electrolyte during battery operation.

The reason why it was necessary to insert the packing 4 during stacking in the conventional stacked battery with the above configuration is that the materials of the electrode plates and diaphragms have a high density (0.94 g/cm 3
or more) polyethylene or polypropylene (0.90
g/cm 3 or more) is used as an electrode plate or a diaphragm with ion exchange properties and fine porosity by kneading fine powder of carbon black and graphite. The dimensional accuracy is low due to the difference in thermal expansion coefficient between the electrode plate and diaphragm and the frame member due to the use of the same type of synthetic resin that can also be integrally molded into the frame portion. If the electrolyte were to leak during repeated charging and discharging by circulating the electrolyte within the battery, there would be a problem in that it would reduce the performance (energy efficiency) of the battery and also harm the environment. In order to prevent such a situation, packing 4 has traditionally been used, but as is clear from Figures 7 and 8, packing 4 occupies an extremely large volume of the entire battery, so the battery itself becomes large. In addition, there was a problem in that the end plates, tightening bolts, nuts, and other members used for tightening had to be large in size.

The frame portion of the diaphragm and the peripheral portion of the end plate are provided with concave and convex portions having appropriate tapers with different inclination angles of concave portions and convex portions on respective surfaces that can be assembled in one direction and that are adjacent to each other when assembled, This is a stacked battery that maintains sealing performance through elastic deformation of the frame member itself that occurs on the contact surface of the uneven portion due to the tightening force during battery assembly.

The stacked battery of the present invention, which has such a structure,

No leakage occurs during electrolyte circulation.

Next, the present invention will be explained based on an embodiment shown in FIGS. 1 to 4. Figures 1 and 2 show the structures of the electrode plates and diaphragms used in the present invention, and Figure 3 shows the combination of the electrode plates and diaphragms shown in Figures 1 and 2 to construct the stacked battery of the present invention.

is an electrode plate frame portion, and 5 is an electrode surface portion at the center thereof. Reference numeral 2 designates a diaphragm frame, 6 a central diaphragm surface, and 7 a space between the surfaces 5 and 6, through which the electrolyte circulates and passes. 8 is a concave portion, 9 is a convex portion, and 10

By doing this, the tapered surfaces 10 and 11 are not elastically deformed over the entire surface, but only a portion of the tapered surfaces 10 and 11 are elastically deformed to ensure the sealing performance needed to ensure sealing when tightening when stacking each member to construct a battery. obtained by force.
