Description of the Related Art Lead storage batteries are widely used as power supplies for industrial equipment such as automobile batteries and uninterruptible power supplies because of their features of being inexpensive and highly reliable. In recent years, cost reduction of lead storage batteries has been very strongly required. In order to reduce the cost of the lead storage battery, it is effective to reduce the amount of lead used as an active material. That is, in order to extract a conventional amount of electricity with a reduced amount of lead, it is necessary to improve the utilization rate of the active material.

Improvements for supplying more ions to the inside of the electrode are being studied.

る。As means for increasing the reaction surface area of the active material layer of the electrode, studies have been made on improving the porosity, increasing the specific surface area, making the electrode plate thinner, and using an electrolyte having a higher specific gravity. In order to improve the porosity and the specific surface area of the active material layer, the amount of water in the paste-like active material produced by kneading with lead sulfur oxide as a main component and diluted sulfuric acid is increased, or the paste is used. A pore-forming agent in the active material (Japanese Patent Application Laid-Open No. 04-36655)
No. 1) is 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 used.

問題点が認められている。[0005] However, lead-acid batteries manufactured using these methods generally have a problem that their life is shortened. In particular, if the amount of water in the paste-like active material is too large, the paste-like active material becomes soft, which makes it difficult to fill the lattice. Because the adhesion with the lattice body of
There is a problem that the active material falls off from the lattice body and the life is shortened in a short time.

る。On the other hand, by mixing a stable powder capable of holding an electrolytic solution such as silica powder into the paste-like active material, the viscosity can be increased even when the paste-like active material has a large amount of water. . However, when an electrode in which a powder such as silica is added to a paste-like active material is used, a problem has been recognized in that a conductive network between active material particles is reduced, and high-rate discharge characteristics are reduced.

ている。[0007] As a means for improving the utilization rate of the active material, attempts have been made to add carbon powder such as carbon or graphite to the active material layer. However, when carbon powder such as carbon or graphite is mixed into the active material by ordinary means, these powders are desorbed from the active material during use, and the effect of their addition is lost. It has been recognized that the carbon powder moves into the separator to cause a short circuit between the positive electrode and the negative electrode.
