鉛蓄電池用ペースト式極板は格子状の支持体（いわゆる
格子）に活物質となるペーストラ塗着してつくられる。BACKGROUND OF THE INVENTION Paste-type electrode plates for 2-benzo lead-acid batteries are manufactured by applying pastera, which serves as an active material, to a lattice-shaped support (so-called lattice).
従来から鉛−アンチモン系合金の鋳造格子が使われてい
たが、近年メンテナンスフリー化の要望を満足させる新

子のつくり方もエキスバンド式が開発された。Traditionally, cast grids made of lead-antimony alloys have been used, but in recent years lead-calcium alloys have been developed as new grids that satisfy the demand for maintenance-free grids, and an expanded method of making grids has also been developed. Ta.

。A typical method for making electrode plates is to place a grid on a filling table made of a cloth belt or the like, and then apply paste on top of the grid. In the expanded type, the grid is a continuous body, so the continuous expanded grid is coated with paste and then cut to a predetermined size to create the electrode plate.

つぎにペーストに含まれる水を押し出しながら圧延して
極板を形成させるものである。Means for Solving the Problems The present invention, in the step of filling the grid with paste, fills the paste so that it is pushed out below the lower surface of the paste grid,
Next, the paste is rolled to form an electrode plate while pushing out the water contained in the paste.
また圧延した後で、格子の下面よりも下側に押し出され
たペーストが、格子の下側に回り込み、格子をペースト

格子骨の表面の１／３以上がペーストで覆われることで
、十分な効果がある。In addition, after rolling, the paste pushed out below the bottom surface of the lattice wraps around the bottom of the lattice, and the paste covers the lattice, and the surface of the lattice bones forming one lattice. A sufficient effect can be obtained by covering 1/3 or more of the area with the paste.
以上のようにペーストラ格子下面よりも下側に押し出す
工程と、これを圧延する工程を行うことに特徴がある。As described above, the paste is characterized by the step of extruding it below the lower surface of the pastera grid and the step of rolling it.

、格子の上側表面には厚いペースト層を形成することは
容易であるが、格子の下面に塗着するのは難しがった。Normally, the paste 2 is applied to the grid 1 using a paste filling machine 3, as shown in FIG.
The grid 1 is usually placed on a support belt 4. Therefore, when applying Paster, it is easy to form a thick paste layer on the upper surface of the grating, but it is difficult to apply it to the lower surface of the grating.

。For example, there is the two-coating method, in which the paste is applied to the surface of the grid, then turned over and the paste is applied again to the back side, or the slurry method, which is used for nickel-cadmium electrodes in alkaline storage batteries, in which a slurry paste is passed through the grid. There are methods such as applying pastera to both sides of the grid. However, the two-coating method has problems such as complicated and large equipment, and poor adhesion of the coating paste in the first and second coatings. On the other hand, the slurry type has problems such as extremely difficult paste formulation for lead-acid batteries. Therefore, in the conventional method, no means was taken to apply the paste to the back side of the grid.

わゆる裏まわりを良くすることが、一つの改善策として
検討されてきた。すなわち、格子の表裏両面を活物質で
被覆することで、格子と活物質との密着性を良好に保と
うとした考え方である。However, when extended-band grids made of lead-calcium alloys are used in batteries, it has come to be assumed that the decrease in cycle life is due to the adhesion between the grids and the active material, and paste is coated on the bottom surface of the grids. , 5'(-/ Improving the so-called back side has been considered as one improvement measure. In other words, by coating both the front and back sides of the lattice with an active material, the adhesion between the lattice and the active material can be improved. The idea is to keep it in good condition.
本発明は完全に格子下面を活物質が被覆する構成になら
なくても、寿命の向上ヲハかることができるペースト式
極板の製造法を見出したものである。The present invention has discovered a method of manufacturing a paste-type electrode plate that can improve the lifespan even if the lower surface of the lattice is not completely covered with the active material.

で、完全に格子を被覆した構成でなくても寿命の向上が
はかられるものと考えられる。That is, it is made by kneading a paste-type electrode plate, water, and dilute sulfuric acid, and when it is filled in the state shown in Figure 2 so that the paste 2 is pushed out below the lower surface 1' of the grid 1, the grid becomes Water seeping out from the paste adheres to the bottom surface. next,
This seeping water is sucked up, and then it is further rolled with a pair of rollers 5 to push out the water from the paste 2. At the same time, the water is sucked up and the paste 2 is made to wrap around the lower surface of the grid, as shown in Fig. 2. As shown in B, the paste near the bottom surface of the grid has a high density and firmly adheres to the grid, so it is thought that the life can be improved even if the structure does not completely cover the grid.

子下面とペーストとの密着を高める上で極めて有効な手
段である。In the method of coating the pastera lattice and at the same time wrapping the paste around the underside of the lattice to fill it, moisture remains at the interface between the lattice and the paste, so even if the structure is coated with active material, the true lattice and active material cannot be formed. This does not mean that the adhesion of the substance has been increased. Therefore, as in the present invention, improving the filling properties of the paste while absorbing the water seeping into the vicinity of the grid is an extremely effective means for increasing the adhesion between the lower surface of the grid and the paste.

。First, place a piano wire with a wire diameter of 0.2 mm as a spacer under the grid up to the tip of the paste filling machine 3, and place the grid 1 on top of it.
Place the rollers and apply Paster to a thickness of 2.0mm, then pass the rolling pair roller 5 all the way through to a total thickness of 1.Bmm.
I made a pole plate. Note that a water absorbing device (not shown) was provided on the pair of rolling rollers 5, so that the extruded water was immediately sucked in, and a battery A' (5) according to the present invention was prepared.
つぎに、ピアノ線をペースト充填機３の内部だけに置い
て格子を浮かしてペーストを塗着し、ペースト充填後す
ぐに圧縮して厚み１．８間とした。Next, the piano wire was placed only inside the paste filling machine 3, the grid was floated, and the paste was applied, and immediately after filling the paste, it was compressed to a thickness of 1.8 mm.
このとき、ペーストｕ格子下面を被覆していた。At this time, the paste U was covering the lower surface of the lattice.
この極板を用いて電池Ｂをつくった。さらに、ピアノ線

い、充電は５人で放電容量の１２０％通電した。A charge/discharge cycle test was conducted using batteries A, B, and C-(H. Discharging was performed by five people until the voltage reached 10.5 V, and charging was conducted by five people to 120% of the discharge capacity.
この充放電全１サイクルとして、初期放電容量の６０係

ができない。本発明のように吸水圧延をしながらペース
トで格子下面を被覆する方法が、活物質と格子の密着性
を高める上で効果がある。As described above, simply forming a structure in which the lower surface of the grating is covered with filled paste cannot provide a sufficiently long life. The method of coating the lower surface of the lattice with paste while performing water absorption rolling as in the present invention is effective in increasing the adhesion between the active material and the lattice.
なお、実施例ではペーストの塗着の際にスペーサとして
ピアノ線を用いたが、本発明はこの方法に限定されるも
のではなく、たとえばベルトの形を変えて、格子の底部

上ｆｆ１ｌｌかることができる。Effects of the Invention In this way, the present invention creates a structure in which the active material protects the lattice by increasing the adhesion between the bottom surface of the lattice and the active material by allowing water to flow out and flow around the bottom surface of the paster lattice. By doing so, it is possible to improve the cycle life including deep discharge, which has been considered a drawback of maintenance-free batteries.
