ている。Conventional technology and its problems There are two types of sealed lead-acid batteries, the retainer type and the gel type, in which the negative electrode absorbs oxygen gas generated during battery charging. The retainer type has a diameter of about 1 inch between the positive and negative plates.
A mat-like separator (hereinafter referred to as a glass separator) made of micron (μm) fine glass fibers is inserted, and this holds the sulfuric acid electrolyte necessary for discharge and isolates both poles. It has become widely used as a backup power source for equipment and computers. However, the cage type has the drawback that the discharge capacity is limited by the amount of electrolyte at low rate discharge because the glass separator is expensive and cannot hold a sufficient amount of electrolyte, and this type of sealed battery is becoming popular. has become an obstacle.
一方、ゲル式はリテーナ式よりも安価であるが、電池性
能か液式やリテーナ式に劣るという欠点があった。On the other hand, although the gel type is cheaper than the retainer type, it has the disadvantage that its battery performance is inferior to the liquid type and retainer type.

とにある。Means for Solving the Problems In order to solve the above-mentioned problems, as a result of intensive research, we have developed a powder of diatomaceous earth, especially one with a diameter of 10 to 500.
It has been found that a battery using a μm electrolyte holder has superior high-rate discharge performance than conventional retainer-type batteries, and superior low-rate discharge performance than gel-type batteries. Furthermore, diatomaceous earth powder is an inexpensive industrial material. Based on these, the present invention solves the above problems and provides a sealed lead-acid battery that is highly productive, inexpensive, and has excellent discharge performance. In a sealed lead-acid battery in which the negative electrode absorbs oxygen residue generated inside the battery, diatomaceous earth powder with a diameter of approximately 10 to 500 μm is filled and arranged in the gap between the positive and negative electrode plates and around the electrode plate group, and sulfuric acid The purpose is to impregnate and retain the electrolytic solution into the powder.

An unformed electrode plate was produced by aging. Next, using these unformed positive and negative electrode plates, a separator shown in FIG. 1 was inserted between the two electrode plates to produce an electrode plate group. Isolator 1 is 2
This is a rod-shaped rod with a wave-shaped part shown in the figure 8 shape. Although the separator 1 shown in the figure is made of acid-resistant synthetic resin, it may also be made of, for example, a band-shaped glass mat or a glass separator. That is, any material may be used as long as it has acid resistance and can isolate both electrodes. The thus produced electrode plate group was inserted into a battery case, and diatomaceous earth powder was filled from above the electrode plate group while applying vibration. Here, the diatomaceous earth powder is 10 μl or less of diatomaceous earth after crushing, 10 to 10

The battery produced here has a nominal capacity of 4.5 Ah. A front view and a sectional view of a storage battery using diatomaceous earth powder are shown in FIGS. 2 and 3, respectively.

電解液を注入したのち、電池の容量試験をおこなった。After injecting the electrolyte, a capacity test of the battery was conducted.
比較のために同じロットの正極板および負極板を用いた
リテーナ式電池Ｆおよびゲル式電池Ｇも試験した。結果
を第１表に示す。For comparison, a retainer type battery F and a gel type battery G using positive and negative plates of the same lot were also tested. The results are shown in Table 1.
この試験結果よりリテーナ式電池Ｆとゲル式電池Ｇとを
比較すると、リテーナ式電池Ｆは電解液比重がやや高い
ためにゲル式電池Ｇよりも高率放電性能が優れていた。Based on the test results, when retainer type battery F and gel type battery G were compared, retainer type battery F was superior in high rate discharge performance than gel type battery G because the specific gravity of the electrolyte was slightly higher.
また低率放電容量はゲル式電池Ｇの方が若干多かった。Furthermore, the low rate discharge capacity was slightly higher in gel type battery G.

乗効果によるものと考えられる。This is because the amount of electrolyte is large. Among the batteries A to E filled with diatomaceous earth powder, especially those with a diameter of 10 to 500 μI
B, C, D according to the invention using diatomaceous earth powder of
Compared to the retainer type battery F and the gel type battery G, the low rate discharge performance was improved by about 8 to 16%, and the high rate discharge performance was improved by about 12 to 47%. This is because the specific gravity of the electrolyte is slightly higher than that of the gel type, it can be impregnated with more electrolyte than the retainer type, there is no need to use a separator that acts as a resistance during discharge, and it has excellent acid diffusion. This is thought to be due to the synergistic effect of the presence of
しかし、直径１０μｍ以下のケイソウ土粉体を充填した
電池Ａおよび直径５００μｍ以上のケイソウ土粉体を充

製時に十分、ケイソウ土粉体を充填できず、したがって
電解液量が減少すること、およびケイソウ土粉体が粗す
ぎると電解液の保持能力が低下することによるものであ
ると考えられる。However, battery A filled with diatomaceous earth powder with a diameter of 10 μm or less and battery E filled with diatomaceous earth powder with a diameter of 500 μm or more are different from retainer type battery F and gel type battery G.
It showed almost the same high rate discharge performance and low rate discharge performance. This is because if the diatomaceous earth powder is too fine, it will not be able to be filled sufficiently during battery fabrication, resulting in a decrease in the amount of electrolyte, and if the diatomaceous earth powder is too coarse, the electrolyte retention capacity will decrease. This is thought to be due to the following.

電池電圧がわずかに低下することもあるが、特に、高率
放電以外の場合には実際上はとんど問題にならない。Table 1 Note that diatomaceous earth powder was used alone in the examples, but in order to further improve the performance, acid-resistant short fibers with hydrophilic properties such as glass short fibers were used in combination with diatomaceous earth powder. Alternatively, for example, a normal separator mainly made of synthetic resin or synthetic fiber may be used in combination. in this case,
Although the battery voltage may drop slightly, this is practically not a problem, especially in cases other than high rate discharge.
