に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for producing electrode plates for lead-acid batteries with high utilization rate and long life.
（従来の技術）
鉛蓄電池用極板の種類は大別すると３種類あるが、最も
一般的なペースト式極板は、酸化鉛を５０％ないし８０
％程度含んだ鉛粉に水と硫酸を混合して練製し、集電体
に充填し乾燥したのちに極性化していた。(Prior art) There are three types of electrode plates for lead-acid batteries, but the most common paste type electrode plates contain 50% to 80% lead oxide.
% of lead powder was mixed with water and sulfuric acid and kneaded, filled into a current collector, dried, and polarized.
（発明が解決しようとする問題点） このペースト式極板は製造方法が比較的容易で。(Problem that the invention attempts to solve) This paste-type electrode plate is relatively easy to manufacture.
さらに急放電特性に優れているなどの長所を有している

率はあまり高くない。たとえば５時間率程度の放電での
極板の利用率は３０％ないし４０％で、５分間率程度の
放電での利用率は５％ないし６％と非常に低い。従来、

いない。このように従来の鉛蓄電池においては、極板の
利用率の向上とサイクル寿命の向」二との両立が困難で
ある欠点があった。Furthermore, although it has advantages such as excellent rapid discharge characteristics, the utilization rate of lead used in the electrode plate for charging and discharging reactions is not very high. For example, when discharging at a rate of about 5 hours, the utilization rate of the electrode plate is 30% to 40%, and when discharging at a rate of about 5 minutes, the utilization rate of the electrode plate is very low at 5% to 6%. Conventionally,
Various attempts have been made to improve this utilization rate, such as lowering the packing density of the reactant in the electrode plate or reducing the number of electrode plates; It has shortcomings and has not been put into practical use. As described above, conventional lead-acid batteries have the drawback that it is difficult to simultaneously improve the utilization rate of the electrode plates and shorten the cycle life.
本発明の目的は、従来の欠点を解消し、利用率の向上と
寿命の向上の両立をはかるとともに、さらに小型軽量化

充分適用できる鉛蓄電池を提供することである。The purpose of the present invention is to eliminate the drawbacks of the conventional batteries, to improve both the utilization rate and the lifespan, and to further reduce the size and weight of the lead-acid battery, so that it can be fully applied to current or expected future uses. The goal is to provide the following.

化し極板とするものである。(Means for Solving the Problems) The method for manufacturing a lead-acid battery plate according to the present invention involves preparing lead powder or lead alloy powder having a lead compound such as lead oxide on the surface thereof, and dissolving the lead compound. A method for manufacturing a lead-acid battery electrode plate in which the solid content is formed into a predetermined shape by treating the powder with a substance such as the above, and the surface of a current collector made of lead or ship metal, with the active metal surface exposed. is treated with a substance that dissolves lead compounds, the exposed active metal surface is brought into contact with it, and if necessary pressurized to form it into a predetermined shape, and then polarized to form an electrode plate.
また正極板は陽極酸化するものである。Further, the positive electrode plate is anodized.
（作 用）

て、その表面に融点の高い釦の酸化物を形成するため、
ニッケル粉末のように焼結ができない。(Function) The ideal plate structure of a lead-acid battery is considered to be a porous body with strong connections, but button or lead alloy forms a button oxide with a high melting point on its surface in the atmosphere. For,
It cannot be sintered like nickel powder.
しかし、二〇釦酸化物を除去することにより、活性な金

改善ができる。By the above method, the lead or lead compound powders coagulate with each other, and their contact surfaces connect with each other to form the porous body of the button.The surface of the current collector is also activated, so it is not the same as lead or silver alloy powder. Combines well. In other words, it becomes a porous body of a button with the current collector as the core. Since these metals are bonded together, their bonding force is strong, and since they are a continuum of metal, they have excellent conductivity, improving the utilization rate and cycle life of the electrode plates for Button TI batteries. It is possible to achieve both. Furthermore, by adjusting the pressure applied to such a metal porous body, the porosity can be adjusted and the strength of the electrode plate can be improved.

、第１回に示すような簡単な構造にすることもできる。Pure lead powder with a diameter of several μm to about 150 μm (lead compounds mainly composed of lead oxide are formed on its surface) and lead-silver alloy powder containing 0.05% silver by weight. (Similarly, lead compounds are formed on the surface) is treated with a substance that dissolves the lead compounds formed on the surface, exposing the active metal surface. As the substance for dissolving, acids such as nitric acid and acetic acid are effective. In the examples, an approximately 5% aqueous acetic acid solution was used. When the above powder is immersed in this acetic acid aqueous solution, the compounds mainly composed of oxides on the surface will dissolve.
The active metal surface is exposed and the metal powder agglomerates. A current collector used in ordinary lead-acid batteries is immersed in this acetic acid aqueous solution, exposing the active metal surface in the same way as the powder. Note that the shape of this current collector is different from the shape of a conventional paste-type electrode plate, and it can also have a simple structure as shown in Part 1.

重量の極板になるように形成時の圧力を調整した。In this example, a current collector having the shape shown in FIG. 1 was used. In this way, the materials each having an active metal surface are formed into a predetermined shape. There are several possible methods for forming this, but it was carried out by filling a predetermined mold with the current collector and powder in a state where acetic acid was resistant to adhesion. In this example, the pressure during formation was adjusted so that the electrode plate had the same shape and weight as the paste-type electrode plate.

電池をＡ。When using these as a negative electrode plate, the above-mentioned electrode plate is washed with water, and when used as a positive electrode plate, it may be anodized in advance before constructing a battery. In this example, before constructing a battery, another negative electrode plate was used as a counter electrode and chemically formed, and then combined with the negative electrode plate and separator described above to construct a battery. A is a battery that uses pure lead powder.

Note that Battery C, which uses a conventional paste-type electrode plate (a battery having the same electrode plate weight as Batteries A and B), was used as a comparative battery. These batteries were charged at a constant voltage of 2.45V per cell for 8 hours and reached 0.
．． A comparison of the cycle life characteristics of each battery is shown in FIG. 2, where one cycle is discharge to 1.75V per cell at 25CA. In the same figure, the results are shown in comparison with the results when the discharge capacity per gram of electrode plate weight at Φθ in the first cycle of a battery using a conventional paste-type electrode plate is assumed to be 100%.
