An electrolytic solution was prepared by mixing it with sulfuric acid with a specific gravity of 1.60 so that the electrolyte had a specific gravity of 96, but it was still in a liquid state. The prepared electrolytic solution was immediately injected into the previously unfilled battery to obtain a closed lead battery B, but the electrolytic solution had turned into a gel when the valve was closed.

とがわかる。An alternate charge/discharge life test was conducted on the sealed lead batteries A and B according to the present invention and the conventional clad lead battery C without replenishing water during the test. As a result, as shown in Fig. 5, the life of the conventional clad type battery C was approximately 80 ==, while the sealed lead battery A according to the present invention had a life of approximately 1900 = -1.
B had a lifespan of about 1700~. The gas absorption rate during this life test was approximately 10 for the sealed lead batteries A and B according to the present invention.
0%, whereas in the conventional clad type battery C, it was of course 0, which shows that the lifespan was extremely short due to the liquid reduction.

ル電解液を充填する必要がなくなる。In the sealed lead-acid battery according to the present invention, the gel electrolyte is filled between the clad plate and the separator, so the electrolyte never leaks in the openings of the tube. In other words, since the large pores in the tube are filled with gel electrolyte, the pores appear microscopic, and the liquid never dries up. Therefore, the sealed lead-acid battery according to the present invention can maintain high capacity and gas absorption rate until the end of its life. In the embodiment, only an example using a cylindrical tube has been described, but the present invention can also be applied to an example using a rectangular tube such as a square, triangular, or flat tube. In this case, the surface of the tube appears to be an upper plane and no recesses are formed, so there is no need to fill the gel electrolyte into the recesses.

強度が高く、より好適である。In addition to the separators shown in the examples, microporous rubber separators, synthetic fiber separators, etc. can also be used as the separators used in the present invention. It is best to use fine glass fibers such as 1μ or less in diameter, and glass fibers thicker than 1μ, preferably 5μ or more, more preferably 10 to 20μ. A separator in which these are randomly interlaced has high mechanical strength and is more suitable.
本発明に使用するゲル化剤としては実施例のごとき珪酸
微粉末のほかアルミニウム、マグネシウム、チタニウム
などの酸化物微粉末が使用でき、更にはそれらの水性分
散液、いわゆるディスパージョンを用いることも勿論可

It is possible.

は無い方が好ましい。The specific gravity of the electrolyte to be injected should be set according to the capacity of the battery, and the amount should be selected appropriately according to the leakage and gas absorption rate during use, but the free electrolyte at the time of injection It is preferable not to have it.

It is also possible to use pb-sb alloys containing very small amounts of antimony.

吸収速度が速いため、凹部の電解液のゲル化剤の濃度の
上昇が迅速に行なわれ、電解液のゲル化が早いという利
点を有している。As shown in Example 1, the method for filling the gel electrolyte in the present invention is to fill the recesses with the gel electrolyte in advance to make the clad type electrode plate appear nearly flat on the top, and then The group may be assembled, or, as shown in Example 2, the electrode group may be housed in a container and then an ungelled electrolyte may be injected to gel it. Furthermore, a gelling agent such as silicic acid powder may be placed in the recessed portion in advance, and an electrolytic solution may be injected later to form a gel. In either case, the performance is almost the same. When injecting non-gelled electrolyte later, it is better to use a separator mainly made of fine glass fibers because the separator absorbs the liquid part of the electrolyte at a faster rate. This method has the advantage that the concentration of the gelling agent in the electrolytic solution increases quickly, and the electrolytic solution gels quickly.
本発明による密閉形鉛電池は円筒状のチューブを使用す

充填して見掛は上極板を平板状にするので、余分の極群
組み立て圧力を掛ける必要がなく、しかも電池が減液し
てもチューブの開孔部分で液枯れすることはない。The sealed lead-acid battery according to the invention is particularly suitable for use when using cylindrical tubes. This is because if you try to fill the recesses formed when multiple cylindrical tubes are lined up with, for example, a flexible separator or porous material, it will be difficult to assemble because it will be necessary to apply excessive pressure to assemble the electrode group. Even if this is done, there is a problem that drying up of the liquid in the chave cannot be avoided. On the other hand, according to the present invention, the recesses are filled with gel electrolyte to make the upper electrode plate look like a flat plate, so there is no need to apply extra pressure to assemble the electrode group, and moreover, the battery is free from liquid loss. The liquid will not dry up in the open part of the tube.
