本発明は、鉛蓄電池の電槽、とくに負極において酸素ガ
スを吸収除去するガス吸収式鉛蓄電池の電槽に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a case for a lead-acid battery, particularly a case for a gas-absorbing lead-acid battery that absorbs and removes oxygen gas at the negative electrode.
従来の技術
ガス吸収式鉛蓄電池は一般に電解液保持体兼セパレータ
としてマット式セパレータを用いていた。Conventional gas absorption lead-acid batteries generally use a mat separator as an electrolyte holder and separator.
このマット式セパレータを極板間に介在させ、電解液量
を極板群にほぼ吸収できる程度に制限し、正極から発生
する酸素ガスを負極で吸収除去して水にもどすタイプの
蓄電池である。This type of storage battery uses a matte separator interposed between the electrode plates to limit the amount of electrolyte to a level that can be almost absorbed by the electrode plates, and the oxygen gas generated from the positive electrode is absorbed and removed by the negative electrode, returning it to water.
この種の電池は一般に液の豊富な電池（一般的には液入

短側面壁に設けられたリブにより極板群が加圧されてい

均一な加圧力がかからず、リブとの接触部のみが加圧さ
れるという現象があった。This type of battery is different from liquid-rich batteries (generally liquid-filled batteries) because the electrode plates are pressed by a thick mat separator, so the active material is less likely to fall off and the risk of short circuits is said to be low. It's here. However, since the ratio of the rib width to the rib pitch where the electrode plate group is pressurized by the ribs provided on the partition wall and short side wall inside the battery case is as wide as 1:6 or more,
There was a phenomenon in which the pressing force was not applied uniformly, and only the portions in contact with the ribs were pressurized.

式鉛蓄電池の機能を低下させることになる。Problems to be Solved by the Invention Therefore, uniform pressure is not applied to the electrode plates and the electrode plate group, and there are places where the active material falls off quickly during use, causing short circuits and shortening the lifespan. I kept it short. In addition, a method has been proposed in which the inner partition wall and short side walls inside the battery case are configured to be flat, thereby applying uniform pressure to the electrode plate and extending the life of the battery. However, in this method, the oxygen gas generated by the positive electrode plate during charging is absorbed and removed by the negative electrode plate, which deteriorates the function of the gas absorption lead-acid battery, which is to reduce the loss of electrolyte.

る。That is, since the surface of the negative picture plate at the end of the electrode plate group is covered by the flat partition wall and the short side wall, the surface that participates in the gas absorption reaction is reduced.

The thickness also needs to be about 1.0 to 2.0 parts. On the other hand 2
If the pore size is 0μ or more, the active material can easily pass through, so the reaction area on the electrode plate is made uniform, and the electrode plate group is made to have a uniform reaction area so that electrode plate deterioration (softening and falling off of the active material) does not concentrate in one area. It was necessary to apply pressure.

ものである。The present invention solves the above-mentioned problems of conventional batteries, namely, to prevent short-circuits caused by non-uniform drop-off of electrode plate active material caused by uneven pressure applied to the electrode plates and active material permeation through the separator, and conversely, to prevent short-circuits. The purpose is to simultaneously solve the problem of a decrease in gas absorption capacity, that is, liquid loss, due to a reduction in the reaction surface that occurs in the method of applying flat pressure to the surface of the negative electrode plate at the end of the electrode plate group to prevent short circuits. It is.
問題点を解決するだめの手段 上記の目的を達成するため、本発明は正極板。A foolproof way to solve problems In order to achieve the above object, the present invention provides a positive electrode plate.

比率を、１：１．５〜１：４に構成したものでちる。In a lead-acid battery case that houses a group of electrode plates consisting of a mat separator that also serves as a negative electrode plate and an electrolyte holder, multiple ribs extending vertically are formed inside the partition wall and the outer walls of the cells at both ends. However, the ratio of the rib width to the inter-rib pitch is 1:1.5 to 1:4.

ト式セパレータの使用を可能にしたものである。In zero or gas absorption type lead-acid batteries, where group pressure is applied to the electrode plate group by a partition wall provided in the battery case and ribs provided inside the outer walls of the cells at both ends, the electrode plate group is reduced by absorbing gas. Since the function of lowering the liquid is required, it is necessary to expose the surface of the negative electrode plate at both ends of the electrode plate group to participate in gas absorption, so the ratio of the rib width to the bupinochi in conventional battery cases is 1. 1. However, even if the rib pitch is wide, even if it is good in terms of gas absorption, it will only partially pressurize the electrode plate and separator, and only the pressurized area will be mainly affected by the reaction. This results in a reduction in battery life. In order to prevent this, the rib width and rib pitch are appropriately configured to make it possible to use a mat type separator with a hole diameter of 2071 or more and a thickness of about 1 to 2.0 holes.

。It has been found that if the ratio of the rib width to the rib pitch is designed to be smaller than 1:1.5, the gas absorption area decreases and the function as a gas absorption lead-acid battery deteriorates significantly. If the ratio of the rib width to the width of the correspondence is designed to be larger than 1=4, only the pressurizing part will be used as described above. In other words, the thickness of the positive electrode, separator, and negative electrode is the thinnest in the area pressurized by the ribs, and the electric resistance is lowered, so it is thought that current passes through this area during charging and discharging. This means that the part where it passes through or is used is most likely to deteriorate, causing the active material to fall off, and also because the separator is the thinnest, it is more likely to short-circuit. However, if the ratio of the rib width to the rib pitch is 1:4 and the ribs are designed to occupy more than 25 inches of the surface area of the electrode plate, the number of areas used by pressure will increase, and the electrode plate will be used evenly. It was found that this did not cause a short circuit. Therefore, the ratio of rib width to rib pitch was set to 1:1. It was designed within S~1:4. In addition, if the rib width is too narrow and is less than 1 deaf, the capped separator or electrode plate may be inserted into m≠1→
It is necessary to use at least one rib because it will significantly deteriorate the battery due to mechanical strength or stress concentration.If the width of the zero rib becomes six or more, the surface area involved in gas absorption will decrease, and the entire electrode plate will become uniform. It no longer participates in gas absorption, and the electrode plates are not used uniformly, resulting in deterioration. From this point of view, it is preferable to design within 5 degrees.

Regarding the relationship between the rib width W and the pitch between the ribs, if the rib width W is 1, the pitch between the ribs is 1.5 to 4 times. The thickness of this mat is 1

上は必要である。The matte separator is designed with a pore diameter of 2 μm or more and a thickness of 1.0 μm, and the width W of the ribs 9 is designed to be 2 mm, and the ratio of the rib width W to the inter-rib pitch P is from 5 mm to 100% (all ribs). We prototyped 36B20 type lead-acid batteries using nine types of containers. The results of the SAE life test of these batteries are shown in FIG. 3. As is clear from FIG. 3, the performance with all ribs (100%) is better in terms of rib width/pitch between ribs. 25% or more is necessary since it decreases significantly when it becomes 26 inches or less.
以上が本発明でリブ幅とリブ間ピッチとの比率を２５％
以上に規定した根拠でもある。ちなみにこれまでの蓄電
池は２０％以下に設計されていた。In this invention, the ratio of the rib width to the pitch between ribs is 25%.
This is also the basis stipulated above. By the way, conventional storage batteries were designed to have a capacity of 20% or less.

がある。Next, looking at the amount of liquid loss, the amount of liquid loss was measured in a room temperature constant voltage overcharge test (20°C x 15.Ov x 100H) using the above battery. As is clear from the figure, the rib width W
The liquid reduction characteristics are better if the ratio of P and the pitch P between the ribs is designed to be large. When this ratio exceeds 67%, the amount of liquid reduction increases rapidly. From this, it is necessary to design it to 67% or less. The present invention has a great effect by setting the ratio of the rib width W to the inter-rib pitch P in the range of 1:1.5 to 1:4 as described above.
