されている。2. Description of the Related Art Generally, a lead-acid battery using a clad type electrode plate as a positive electrode plate has a positive electrode active material filled in a tube, so that the active material does not fall off even if charging and discharging are repeated. It is known that it has a longer life than the lead acid battery used. Conventionally, when a lead storage battery is hermetically sealed, a retainer method or a SiO 2 method in which a fine glass mat is placed between the positive and negative electrode plates to hold an electrolytic solution in the glass mat.
A gel electrolyte solution system is adopted in which an inorganic oxide such as the above is added, and a sol-like electrolyte solution is injected to cause gelation in the battery to make the electrolyte solution non-fluidized. When the lead-acid battery is to be hermetically sealed, the gel electrolyte method is used because the retainer method makes poor contact between the positive electrode plate and the glass mat.

本発明は、上記問題点に鑑みてなされたものであって、
その目的とするところは、電解液の減少を抑え、長寿命
のクラッド式密閉形鉛蓄電池を提供することにある。In the sealed lead-acid battery, the oxygen gas generated from the positive electrode plate at the end of charging is absorbed by the negative electrode plate to prevent loss of water in the electrolytic solution. In the retainer method, appropriate pores exist in the glass mat, and the gas generated from the positive electrode plate moves to the surface of the negative electrode plate through the pores and is absorbed by the active material of the negative electrode plate. On the other hand, when the gel electrolyte is used, cracks in the gel electrolyte serve as a gas transfer path from the positive electrode plate to the negative electrode plate, and a gas absorption reaction occurs as in the retainer type. However, in the gel method, the oxygen gas initially generated from the positive electrode escapes upward along the separator, which hinders the gas absorption reaction. Therefore, the gel method has a lower gas absorption reaction than the retainer method. For this reason, in the clad-type sealed lead-acid battery, the amount of the electrolyte solution is reduced and the capacity is lowered, and it is difficult to fully utilize the characteristic of the clad-type original long life.
The present invention has been made in view of the above problems,
It is an object of the present invention to provide a clad-type sealed lead-acid battery that suppresses the decrease in electrolyte and has a long life.
