の改良が検討されている。2. Description of the Related Art In recent years, there has been an extremely strong demand for improvement in high-rate discharge characteristics of lead-acid batteries. As means for improving the high-rate discharge characteristics of lead-acid batteries, improvements have been made to increase the reaction surface area of the positive electrode active material, and to provide more positive electrode active material with sulfate ions, which are substances involved in the discharge reaction. Are being considered.

という問題点がある。As means for increasing the reaction surface area of the positive electrode active material, studies have been made on increasing the porosity and specific surface area of the positive electrode active material layer, making the positive electrode plate thinner, and using an electrolytic solution having a higher specific gravity. In order to improve the porosity of the positive electrode active material, the amount of moisture in the paste active material containing lead as a main component and kneaded with dilute sulfuric acid is increased, or a pore-forming agent is added to the paste active material (Japanese Patent Application Laid-Open No. -366551) is generally used. As a method of increasing the specific surface area of the positive electrode active material layer, a method of increasing the concentration of dilute sulfuric acid used during chemical formation is generally used. However,
Batteries manufactured by using these methods have a problem that the life is shortened.

の放電電圧が低下するという欠点がある。[0004] In the case of a sealed lead-acid battery, an attempt has been made to increase the thickness of the retainer to retain more electrolyte in the retainer as a means for supplying more sulfate ions to the positive electrode active material. By using this method, the discharge time of the battery during high-rate discharge can be lengthened. However, since the distance between the positive electrode plate and the negative electrode plate becomes longer, the internal resistance increases, and as a result, there is a disadvantage that the discharge voltage of the sealed lead-acid battery decreases.

Production of raw material lead powder and pulverized lead powder A raw material lead powder mainly composed of lead monoxide is prepared from a lead lump using a ball mill type lead powder producing machine. Thereafter, the raw material lead powder is pulverized using a fan type pulverizer made by Hosokawa Micron, and five types of pulverized lead powders (pulverized lead powders A to
E, Table 1) was prepared. The raw material lead powder and the five types of ground lead powders (ground lead powders A to E) each have a "whisker-like" metallic lead in the center of the powder and the periphery thereof is covered with lead monoxide. You are. The degree of oxidation of these powders as a whole is about 80%. The average particle diameter of the raw material lead powder, the pulverized lead powder, and the lead described below was measured using a laser diffraction type particle size distribution analyzer (model LA-500) manufactured by HORIBA. Then, the average particle diameter (generally called Dp50) is the particle diameter equivalent to 50% in the cumulative value with respect to the total particle volume.
It was specified. The particle size of the metallic lead present in the center of the raw material lead powder or the ground lead powder was measured by the following method. That is,
After embedding the above-mentioned raw material lead powder or crushed lead powder in an epoxy resin and solidifying it, it is cut together with the epoxy resin and the cross section is polished. And a Olympus metal microscope (BH-2
), The dimensions of a total of 100 metallic leads were measured, and the average value was calculated (hereinafter referred to as the particle diameter of metallic lead). As shown in Table 1, the reason why the particle size of the metallic lead is larger than the average particle size of the raw material lead powder or the crushed lead powder is due to the difference in the measurement method as described above.
