法であった。2. Description of the Related Art In recent years, the maintenance-free nature of lead-acid batteries has been strongly demanded by society. Free batteries are frequently used. However, when the amount of antimony is suppressed, the maintenance-free property, that is, the liquid-reducing property, tends to decrease the deep discharge cycle life, as opposed to improving the performance of self-discharge. As one solution to this problem, a technique has been disclosed in which antimony, which should have been removed once, is applied to the lattice surface as another alloy layer. In particular, a method of integrating an alloy foil containing another antimony on a matrix alloy sheet serving as a base by rolling and expanding the foil is an excellent method in that the properties of the lattice surface can be easily changed.
上記により、深放電サイクル寿命は大幅に改善された
が、新たな２つの課題が発生した。Although the deep discharge cycle life was greatly improved by the above, two new problems occurred.
発明が解決しようとする課題 第１の課題は、アンチモンを含む合金の薄層が格子表

ことが判明した。Problems to be Solved by the Invention The first problem is that the liquid reduction characteristics are lower than when a thin layer of an alloy containing antimony is not formed on the lattice surface at all. This phenomenon is caused by the presence of antimony with a low hydrogen overvoltage in the battery system.A more detailed analysis revealed that the concentration of antimony used on the surface was extremely large, and that a thin layer of alloy containing antimony was It was found that the problem was not the problem in the area surrounded by the active material, but the antimony in the completely exposed area had an adverse effect.

よっては耐食性を著しく低下せしめる結果になる。The second problem is that in the process of forming a lattice from an alloy ingot to an alloy sheet and further expanding, antimony and other metals coexist in the base sheet, which causes a significant problem in corrosion resistance. For example, if the base is an antimony alloy, there is no problem. However, when the lead-calcium-based alloy most frequently used for maintenance-free is the base, the corrosion resistance is significantly reduced by mixing antimony into the calcium alloy.
Here, the expanded sheet is obtained by rolling the slab, but not only keeps the sheet thickness and width constant, but also after rolling, both ends in the rolling direction are easily cracked, and after rolling, trimming is performed. It is common to cut off both ends. The removed chips are generally returned to a melting pot for slab production. Although this material does not have to be returned, it cannot be economically disposed of, and if a thin layer containing antimony was present in the chips, antimony would be mixed into the substrate. Would. As a result, the amount of antimony in the lattice substrate cannot be controlled, and at the same time, depending on the conditions, the corrosion resistance is significantly reduced.

の製造法を開示するものである。Means for Solving the Problems The present invention forms a thin layer of an alloy containing antimony on the surface of a lead alloy sheet, and in a configuration using a grid obtained by expanding the thin layer, a thin layer of the alloy containing antimony is formed except for the mesh portion. The most efficient configuration is that the part with the thin layer is surrounded by the active material, and the waste material such as trimming is reused at the stage of the lattice manufacturing process. As a specific method to most effectively prevent the incorporation of antimony that affects steel, a central part of the slab of the base metal alloy and the alloy foil containing antimony are rolled and integrated by rolling at the center in the traveling direction. The non-deployed part is set, the mesh formation position to be expanded on both sides is set, and the position that does not exceed the dimension is continuously rolled and integrated, and furthermore, The present invention discloses a method for manufacturing a lead storage battery electrode plate, wherein trimming is performed to adjust a sheet to a desired width in a region not containing thymon.

にアンチモンを含む合金の薄層が活物質層から露出して
形成されていないことが極めて重要である。Action When a thin layer containing antimony is surrounded by an active material, most of the antimony migrates into the active material,
There is almost no outflow of the electrode plate. However, if the thin layer containing antimony is exposed without being surrounded by the active material, antimony flowing out of the grid of the positive electrode plate precipitates on the negative electrode plate, which causes a reduction in the liquid reduction characteristics. In this respect, in the present invention, a thin layer of an antimony-containing alloy is exposed from the active material layer in the lower frame bone of the expanded lattice and the ear portion and the upper frame bone obtained from the non-deployed portion at the center of the sheet. It is extremely important that they are not done.

命の両立を図ることができる。Therefore, during the production of the sheet for expanding, in order to trim the rolled sheet according to the present invention, it is clear that the layer containing antimony is not included in the removed chips, the antimony to the base material It is possible to achieve both maintenance-free performance and deep discharge life while suppressing the risk of contamination.
なお重要なのは活物質層のすべてにアンチモンを含む
薄層が必要かどうかが本発明の鍵となったが、以下の実
施例によって、本発明の方法がそのメカニズムにおいて
当現象に適切であるとの判断に至った。It is important that whether or not a thin layer containing antimony is necessary for all of the active material layers was a key to the present invention. According to the following examples, the method of the present invention is considered to be suitable for this phenomenon in its mechanism. I came to a decision.
実施例 以下実施例によって本発明の効果をのべる。Examples The effects of the present invention will be described below with reference to examples.

薄層はＲの幅をもち上記t3,t1とt2,t4の間に設定されて
いる。ここでＱ＞Ｒが本発明の効果を与える重要な鍵で
ある。FIG. 1 shows a sectional view and a partial plan view of an expanding sheet embodying the present invention. Where 1 is the sheet base material,
Reference numeral 2 denotes a thin layer obtained by rolling and integrating an alloy foil containing antimony provided thereon. In the center of the sheet, a non-deployed portion P for forming the ears of the electrode plate is set between t 1 and t 2 ,
The set positions for forming a net having a width of Q on both sides are t 3 and t
It is shown between 1 and t 2 , t 4 . Thin layer of an alloy containing antimony is set between said t 3, t 1 and t 2, t 4 has a width of R. Here, Q> R is an important key that gives the effect of the present invention.
以上のごとき圧延一体化ののちＱの範囲で網状体が形
成されているので、t3およびt4の更に外側でトリミング
されることになる。After the rolling integration as described above, a net is formed in the range of Q, so that trimming is performed further outside of t 3 and t 4 .
従って網状体前のトリミング部３および中央での非展
開部より耳部を切り出した残りの屑中には一切の高濃度

再利用し母材に用いたとしても何ら問題が発生しないこ
とは明らかである。Therefore, there is no thin layer containing high-concentration antimony in the trimming portion 3 in front of the reticulated body and in the remaining debris cut out of the ear portion from the undeployed portion at the center. Therefore, it is apparent that no problem occurs even if it is reused industrially and used as a base material.

An experiment was conducted to determine the degree of freedom.

The respective plates are X 1 , X 2 , X 3 , X 4 , X 5 , X 0 and Y 1 , Y 2 , Y 3 ,
Y 4 and Y 5 were set. The electrode plate was obtained by applying and drying an active material paste on a mesh portion according to a conventional method.
ついで深い放電寿命サイクルについては上記極板を用

べた。また寿命試験中の減液速度も同時に調べた。その
結果を第２図，第３図に示す。Next, for a deep discharge life cycle, a battery of about 50 Ah was constructed using the above electrode plate, discharged at 25 A for 1 hour, and charge was performed at a maximum current of 25 A and a maximum voltage of 14.8 V for 5 hours. Do, 30 every 25 cycles
The voltage was measured at 30 seconds at 0 A, and the life time of reaching 7.2 V was examined. The rate of liquid reduction during the life test was also examined. The results are shown in FIGS. 2 and 3.

域では濃度効果が顕著であった。As can be seen from the figure, the higher the concentration of antimony applied to the surface, the longer the life is improved.It is not necessary to include antimony in the entire reticulated body, and the concentration effect is remarkable in the region where the R / Q ratio is small. there were.
一方、減液速度については、R/Qの比率が110％になる

思われる。アンチモンの濃度が高いだけその被害は大き
い。On the other hand, the rate of liquid reduction was found to increase sharply when the R / Q ratio reached 110%, which eluted directly from the antimony layer not surrounded by the active material and reduced the liquid reducing property. I knew it was there. Further, even at 100%, the thin layer containing antimony slightly worsens,
It is considered that the distance between t 1 and t 2 or outside t 3 and t 4 exceeded the setting. The higher the concentration of antimony, the greater the damage.

は、メンテナンスフリー性の新たな課題が発生する。On the other hand, the behavior of the deep discharge life and liquid reduction characteristics depending on the antimony content contained in the thin layer portion was examined. That is, an electrode plate was prepared by variously changing the antimony content of the thin layer portion, and the same experiment as described above was performed. The R / Q value was unified at 90%. The result is shown in FIG. In FIG. 4, the abscissa plots the antimony content contained in the thin layer portion with respect to the lattice weight, and the ordinate plots the life index and the liquid reduction index of the deep discharge life cycle, and plots the results. It can be seen that the life cycle number is remarkably improved if antimony is present to some extent, but it is understood that the liquid reduction property is reduced when the antimony content exceeds 0.4%. Therefore, the appropriate amount of antimony with respect to the lattice weight is 0.4% or less, and when it is more than 0.4%, a new problem of maintenance-free property occurs.

Is prevented from being mixed into the base material, and its industrial value is extremely large.
