の密閉電池の普及に障害となっている。2. Description of the Related Art There are two types of sealed lead-acid batteries of a type in which oxygen gas generated during charging of a battery is absorbed by a negative electrode, a retainer type and a gel type. In the retainer type, a mat-like separator (glass separator) made of fine glass fiber is inserted between the positive electrode plate and the negative electrode plate, thereby holding the sulfuric acid electrolyte required for discharge and isolating the two electrodes. No maintenance, no leakage,
In recent years, it has become widely used as a backup power source for portable devices and computers, taking advantage of its features such as position-free. However, on the other hand, there are many factors that increase the manufacturing cost of the battery, such as the expensive glass separator and the need to strongly press the electrode plate group, so that the strength of the battery case must be increased. There are drawbacks such as poor low-rate discharge performance, which has hindered the spread of this type of sealed battery.

とである。On the other hand, the gel type is less expensive than the retainer type, but has a drawback that the battery performance is inferior to the liquid type and the retainer type. Therefore, in order to solve these drawbacks, a sealed lead-acid battery that is neither a retainer type using fine glass fibers nor a gel type using a gel electrolyte has been proposed. This uses silica fine powder (accurately, hydrated silicon dioxide (SiO 2 · nH 2 O), but here abbreviated as silica fine powder) as a holding material for the electrolytic solution. A battery having a configuration in which the above silica fine powder is filled in a gap with a plate and around an electrode plate group. Silica fine powder is an inexpensive material that is mass-produced and commercially available, and has excellent acid resistance and excellent electrolyte retention ability, and is therefore a new material that is excellent as an electrolyte retention material for sealed lead-acid batteries. However, this new sealed lead-acid battery also has the following problems. In other words, since the silica fine powder is a very bulky fine powder, it is difficult to densely fill the gap between the electrodes and the periphery of the electrode group, and it is difficult to pour the electrolyte solution into the filled powder layer. It takes a long time.

に基づいて説明する。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks of the conventional sealed lead-acid battery, and provides an inexpensive sealed lead-acid battery having excellent discharge performance. The gist of the invention is to utilize the property of absorbing well. This silica fine powder has fine primary particles of 10 to 40 millimicrons and a large specific surface area, so even if a large amount of sulfuric acid electrolyte solution is added, the state of the powder is maintained, and the filling of the powder in the battery case is possible. Not only is it easy, but also because the sulfuric acid electrolyte can be absorbed in advance, the amount of electrolyte finally injected can be reduced, and the silica powder that has absorbed the electrolyte has good liquid permeability, As a result, it was found that the time required for filling and pouring the powder can be significantly reduced. Hereinafter, the present invention will be described based on embodiments.

も好ましい。Example In this example, a commercially available silica fine powder having a primary particle diameter of 10 to 40 mm was used. This fine powder is a bulky powder in which primary particles are aggregated to form secondary or tertiary particles of 50 to 200 microns, and have a large specific surface area and a high ability to absorb sulfuric acid. When sodium silicate and sulfuric acid are reacted, it can be easily produced as hydrated silicon dioxide like Na 2 SiO 3 + H 2 SO 4 → SiO 2 · H 2 O + Na 2 SO 4 ,
It is produced in large quantities as an inexpensive industrial material. Therefore, an aqueous sulfuric acid solution as an electrolytic solution was added to the silica fine powder, and a powder impregnated with sulfuric acid was experimentally manufactured.
The method of making is very simple, it is only necessary to mix silica fine powder and sulfuric acid. That is, when sulfuric acid is added to the silica fine powder, the added sulfuric acid is absorbed by the silica fine powder to form a lump, but is easily broken by stirring to form a uniform powder. However, what should be noted here is that if the amount of sulfuric acid added is too large and the stirring is too intense, the mixture does not turn into powder but paste. If a crushing force is applied, the sulfuric acid absorbed by the powder oozes out and becomes a paste, so that such a stirring method must be avoided. Light stirring is most preferred.

The properties of the prepared powder were powdery until 1.78 ml of sulfuric acid per 1 g of fine silica powder was impregnated. However, at 1.92 ml, the powder became slightly moist and the feeling of dryness disappeared.

浸シリカ微粉体を極間および極板群の周囲に充填した。Next, a sealed lead-acid battery was manufactured using these sulfuric acid-impregnated silica fine powders. The battery has a nominal capacity of 4.5Ah,
It consisted of three positive and negative electrode plates which had been formed and dried, and two spacers each of 2 mm wide and 1.5 mm thick acid resistant synthetic resin were inserted between the electrodes. Then, the sulfuric acid-impregnated silica fine powder shown in Table 1 was filled between the electrodes and around the electrode plates.

In the figure, 1 is a positive electrode plate, 2 is a negative electrode plate, 3 is a sulfuric acid impregnated powder, 4 is a battery case, and 5 is a liquid port. Table 2 shows the filling time when the fine powder was filled into the battery case under the conditions of a vibration intensity of 2 G, an amplitude of 0.5 mm, and a vibration frequency of 60 times per second.
硫酸含浸シリカ微粉体の充填量は元原料のシリカ微粉

Ｄでは、シリカ微粉体100gに比重1.30の希硫酸を115g含
浸させたので、硫酸含浸シリカ微粉体の充填量は 15＋（15/100）×115×1.30＝37.4gとなる。 The filling amount of the sulfuric acid-impregnated silica fine powder was such that the raw material silica fine powder was 15 g in all cases. For example, in Battery D, since 100 g of silica fine powder was impregnated with 115 g of dilute sulfuric acid having a specific gravity of 1.30, the filling amount of sulfuric acid-impregnated silica fine powder was 15+ (15/100) × 115 × 1.30 = 37.4 g.

表に示したように、No.6の粉体まではさらさらした粉状
であったがNo.7になるとやや湿った粉状となったことか
ら、充填性が低下したものと思われる。As is clear from Table 2, the filling time becomes shorter and the filling becomes easier as the amount of the diluted sulfuric acid having a specific gravity of 1.30 impregnated in the silica fine powder increases. However, when the powder of No. 7 with the largest amount of sulfuric acid impregnation is used, the filling time becomes longer, and the sulfuric acid impregnation amount seems to be limited. This is the first
As shown in the table, up to No. 6 powder was in a powdery state, but in No. 7, it became a slightly moist powder, and it is considered that the filling property was reduced.

に要した時間を、第４表に容量試験の結果を示す。The test battery filled with the silica fine powder was injected with dilute sulfuric acid having a specific gravity of 1.30, charged for the first time at 0.6 A for 18 hours, and then subjected to a capacity test. Table 3 shows the injection amount and the time required for injection of 1.30 diluted sulfuric acid, and Table 4 shows the results of the capacity test.
第３表において希硫酸の注液は次のようにした。電池

た硫酸含浸シリカ微粉体37.4g中には硫酸電解液が ｛115/（100＋115×1.30）｝×37.4＝17.3 存在するので、注液硫酸量としては46−17.3＝28.8mlで
よいことになる。In Table 3, the diluted sulfuric acid was injected as follows. Battery A uses the raw material of the silica fine powder. Since the injection amount of this battery was 46 ml, the total injection electrolyte amount of the batteries B to G filled with the sulfuric acid impregnated silica fine powder was 46 ml. And Therefore, in the batteries B to G, since the electrolytic solution is impregnated in the silica fine powder in advance, the amount of the dispensed liquid may be small. For example, in the battery D, the sulfuric acid electrolyte is {115 / (100 + 115 × 1.30)} × 37.4 = 17.3 in 37.4 g of the filled sulfuric acid-impregnated silica fine powder, so the amount of sulfuric acid injected is 46-17.3 = 28.8. ml will do just fine.

微粉体を充填した電池Ａの注液量46mlの約２分の１であ
るが、注液に要した時間は、電池Ａの35分に対して6.8
分と約５分の１に短縮されている。 In Table 3, the time required for injection is the time required for the diluted dilute sulfuric acid to be completely absorbed by the fine silica powder and free dilute sulfuric acid to disappear. As a result of the measurement, as shown in Table 3, G could be injected first in the order of A, B, C. This is because silica fine powder was impregnated with dilute sulfuric acid in advance,
This is because not only the amount of injected sulfuric acid was small, but also the permeation rate of dilute sulfuric acid was high. This can be understood, for example, by comparing the time required for injecting the batteries A and E. That is, the injection amount of the battery E is 22.9 ml, which is about one half of the injection amount of 46 ml of the battery A filled with the raw material silica fine powder not impregnated with sulfuric acid. Is 6.8 for 35 minutes of battery A

To G, the same positive and negative electrodes were used. That is the battery H in Table 4. The 0.2 C discharge capacity of the batteries A to G was improved by about 10% as compared with the conventional product H. In addition, even with a high-rate discharge performed at 30 A, a discharge capacity 14 to 27% higher than that of the conventional product at 1 minute and 32 seconds was obtained. In this embodiment, a spacer made of a synthetic resin is inserted between the poles. However, a commonly used separator for a lead storage battery may be inserted. In particular, a ribbed or corrugated separator is advantageous because a certain gap can be provided between the poles.

る。 The present invention is not limited to the above embodiment, for example, filling the battery case with a powder previously impregnated with an appropriate amount of water into the fine powder,
Thereafter, in the method of injecting a sufficient amount of sulfuric acid electrolyte necessary and necessary for discharging the battery, there is an advantage that the filling of the powder and the injection of the electrolyte are facilitated, and various applications are considered.
