Abstract

PURPOSE:To install an electrode group easily into a container by stacking spacers made of an acid-proof member having a swelling property in the electrode group, and applying pressure to the electrode group due to the swelling of the spacers caused by electrolyte. CONSTITUTION:An electrode group is constituted of positive plates 1, negative plates 2, separators 3 and glass mats 4. Spacers 5 is made of an acid-proof member which has a swelling property and is prepared either by mixing a base such as EPDM rubber with a matter having an exceptionally high moisture- absorbing property, such as aerogel, or by mixing an anion exchange resin with tetrafluoroethylene. Thus, when an electrolyte 7 made of dilute sulfuric acid is poured into a container 6 after the above electrode group in which the spacers 5 are stacked is installed in the container 6 at a small pressure of around 10kg/ cm<2>, the spacers 5 swell due to the electrolyte 7, and a desired pressure can be applied to the electrode group.

Although it is necessary to set the pressure to 0 to 50 Kyl-, there is a problem in that if a sufficient tension force is applied at the time of assembling the pole group, the assembling operation becomes extremely complicated.

This will be explained in detail with reference to the drawings. That is, in the drawings, 1 is an anode plate, 2 is a cathode plate, 6 is a separator, and 4 is a glass mat, and the above constitutes an electrode group. Further, 5 is made of a swellable acid-resistant material formed by mixing a highly cross-linked and water-absorbing substance such as aerogel with an EPDM rubber base, or by mixing an anion exchange resin and tetrafluoroethylene. It is a spacer.

。As described above, according to the present invention, the electrode group can be easily stored in the battery case, and a high stress is applied to the electrode group during use of the battery, so that the anode active material on the -electrode plate can be easily stored in the battery case. It is possible to prevent deterioration of the four ponds due to softening and falling off due to shrinkage, and it has high industrial value.
