る。On the other hand, the environment in which lead storage batteries are used has recently become particularly severe. For example, in automobiles using lead-acid batteries for automobiles, the amount of heat generated increases due to an increase in the cooler installation rate and an increase in the output of the engine. On the other hand, a lack of cold air due to slant nose and high-density arrangement of various electrical components As a result, lead-acid batteries installed in the bonnet are easily exposed to high temperatures,
In summer it has been observed to rise to nearly 100 ° C.

In addition, lead-acid batteries tend to be more deeply discharged due to an increase in electric devices such as rear wipers and power windows, an increase in accessories such as audio equipment, and an increase in dark current due to computerization.

Among them, particularly high temperature is an important problem. The reason for this is that if the electrode plate is used for a long time at a high temperature, not only the deterioration of the electrode plate is promoted, but also the negative electrode plate near the lower surface of the strap may be abnormally corroded in some cases.

である。SUMMARY OF THE INVENTION In order to prevent the corrosion of the negative electrode plate, the present invention performs a number of tests, and specially manufactures the battery during the test, especially the state near the negative electrode strap in the electrolyte. By carefully observing with the acid-resistant lead-acid battery internal observation device and analyzing the results in detail,
When a glass mat is not used for the separator, the distance from the upper end of the separator to the lower surface of the negative electrode strap is 4 mm or more. Is set to be 6 mm or more, which makes it possible to prevent the negative electrode plate from being corroded even when used under severe conditions as described above.

A general lead-acid battery for automobiles prepared by a cast-on-strap (COS) method using an alloy composed of selenium by weight was prepared. At this time, the length of the negative electrode plate ear 1a was changed variously, and the distance A from the upper end of the glass mat to the lower surface of the negative electrode strap was changed to 2, 4, 6, 8, and 10 mm. As a matter of course, the length of the positive electrode plate is also changed in the same manner as the negative electrode plate.

For 8 weeks. To facilitate the test, the water tank temperature was set to 80 ° C and the specific gravity of the electrolyte was set to 1.40 (20 ° C).
Conversion). Because of the test at high temperature, water decomposed and evaporated violently. During the test, water was replenished once a day to the upper specified liquid level line (upper level). During the test, the vicinity of the negative electrode strap in the electrolyte was carefully observed using a specially manufactured device for observing the inside of a lead-acid battery having acid resistance. After the test, the battery was disassembled, the state of corrosion of the negative electrode lug near the lower surface of the negative electrode strap was observed, and a detailed analysis was performed while comparing with the state near the negative electrode strap during the test.
【００１２】解析結果を表１に示す。The results of the analysis are shown in Table 1.
【００１３】[0013]
【表１】 表１から明らかなように，ガラスマット上端から負極ス

少なくなり，負極耳の腐食も少なくなって，実用上問題
になるレベルではなくなった。Ａがさらに８，１０ｍｍ
と長くなると，ガス溜りもわずかになり，負極耳の腐食
もわずかになった。[Table 1] As is evident from Table 1, when the distance A from the upper end of the glass mat to the lower surface of the negative electrode strap was 4 mm or less, gas accumulation on the lower surface of the negative electrode strap was large, and the degree of corrosion of the negative electrode ear was moderate to large. , A becomes 6 mm, the gas pool is reduced, the corrosion of the negative electrode ear is also reduced, and it is not at a level that poses a practical problem. A is 8,10 mm
As the length became longer, the amount of gas accumulation became smaller, and the corrosion of the negative electrode ear became smaller.
【００１４】Ａが長くなるとガス溜りが少なくなるの

へ放散するチャンスが多いためではないかと推測され

層破壊されやすくなる。The reason why the gas pool becomes smaller when A is longer is not because oxygen and hydrogen gas generated from the positive and negative electrode plates during charging do not accumulate on the lower surface of the strap but have a large chance to diffuse to other portions. It is guessed. Further, the reason why the corrosion of the negative electrode ear is more severe as the amount of gas accumulation increases is not clear, but is considered as follows.
In other words, the accumulation of gas prevents the surface of the negative electrode ear from being covered with a sufficient electrolytic solution, and is covered with a very thin electrolytic solution film. As a result, even during charging, the surface of the negative electrode ear is not sufficiently polarized to the cathode side, and is located near the equilibrium potential of lead / lead sulfate. Then, the formed film of lead sulfate is unstable, and is more easily destroyed by generated gas or the like.

A grid obtained by expanding a rolled sheet made of 65% by weight calcium-1.3% by weight tin-0.01% by weight aluminum alloy was used. A glass mat was not used for the separator, and a surface in contact with the negative electrode plate was used. Relatively low (about 0.25m
m) A microporous polyethylene separator provided with fine ribs with a pitch of about 5 mm, and a relatively high (about 0.5 mm) surface with rough ribs with a pitch of about 10 mm on the surface in contact with the positive electrode plate. (Substrate thickness 0.25 mm). Further, this microporous polyethylene separator was formed into a bag shape, and a negative electrode plate was placed therein.

傾向がみられたが，本実施例の場合には，Ａが４ｍｍと

ベルではなかった。[Table 2] As in the case of the first embodiment, the longer A is, the smaller the gas accumulation on the lower surface of the negative electrode strap, and the lower the tendency of the negative electrode ear corrosion. However, in the present embodiment, A is relatively short, 4 mm. However, there was little gas accumulation and it was not at a level that would pose a practical problem.

やかに放散したためではないかと推測される。Although the tendency is the same, it is not clear why gas accumulation on the lower surface of the negative electrode strap was small even if A was shorter than in the case of Example 1, but in this embodiment, a glass mat was used. It is presumed that the generated oxygen gas or hydrogen gas was dissipated more quickly than when the electrode plate was pressed with a glass mat because the ribs were provided on the separator.
