本発明はゲル状電解液を用いたクラッド式密閉鉛蓄電池

、さらに活物質の軟化、脱落で寿命性能が劣るという問
題点があった。Conventional technology and its problems Sealed lead-acid batteries using a gel electrolyte are usually limited to base type batteries. This is because in clad batteries, the gel separates in the tube, impairing the discharge performance of the positive electrode plate. However, in paste-type sealed lead M lightning ponds, the grid is lead-free.
Since an alloy such as a calcium alloy that does not significantly reduce the hydrogen overvoltage is used, there is a problem in that the lattice corrodes and stretches during deep charging and discharging, and the active material softens and falls off, resulting in poor life performance.

チューブであることが望ましい。Means for Solving the Problems The present invention provides a clad sealed lead-acid battery using a lead alloy core that does not significantly reduce hydrogen overvoltage by making the structure of the tube sparse to prevent gel separation in the tube portion. It has improved discharge performance and has a specific gravity of 1.2 at 25℃.
()0 electrical resistance in dilute sulfuric acid is 0.002Ω-d
It is particularly desirable that the tube has a water flow rate of 200 cc/rain ·- or more based on the pressure of 10 Cl+ water column in water.

ブで電解液が分離されることはなく、充分な放電性能が
得られ問題はない。Function: In conventional liquid batteries, the structure of the tube needs to be made dense to prevent the positive electrode active material from softening and falling off. The electrical resistance of this product is usually 0.003Ω・di2. This is the above, and the water flow rate is 150 cc or less. Even if the tube has such a dense structure, in a normal battery in which the electrolyte is in a liquid state, the electrolyte will not be separated by the tube, and sufficient discharge performance can be obtained without any problems.
しかし、電解液をゲル状とした場合には、チューブでゲ

落が無く、チューブの組織を疎にしても寿命に悪影響を
及ぼすようなことはない。In the present invention, since the structure of the tube is made sparse, separation of the gel in the tube portion is prevented and the discharge performance is not impaired. In addition, when the electrolyte is in gel form, the electrolyte has the ability to retain the active material, so the active material does not soften or fall off, and even if the structure of the tube is made loose, it will have a negative effect on the lifespan. There is no such thing.

This tube has an electrical resistance of 0.0 in dilute sulfuric acid with a specific gravity of 1.200 at 25°C.
02Ω・6m2 or less. It is desirable that the water flow rate be 200cc/min-4 or more under the pressure of a 10cm water column in water. 3 is a positive electrode active material, 4 is an upper lead alloy joint, and 5 is a lower joint made of plastic.

正極端子、１２は負極端子である。6 is a negative electrode plate, and like the positive electrode plate, it is preferably made of a lead alloy that does not significantly reduce hydrogen overvoltage. 7 is a separator, 8 is a battery container, and 9 is a gel electrolyte, for example, a mixture of dilute sulfuric acid and silica particles. 10 is an exhaust section having a valve function, 11 is a positive terminal, and 12 is a negative terminal.

、脱落を防いでいる。Glue 9 not only fills the void in the battery case, but also fills in the separator 7.
and also fills the porous voids in tube 2. This gel is a semi-solid gel due to weak bonds between silica particles, sulfuric acid, and water, and suppresses and supports the surface of the active material to prevent it from softening and falling off.
活物質は鉛イオンの溶解、析出で充放電を繰返すと形態
変化や結合の切断を生じるが、電解液がゲル状であると
この鉛イオンの溶解、析出を抑える効果もある。When the active material is repeatedly charged and discharged due to the dissolution and precipitation of lead ions, its shape changes and bonds break, but a gel-like electrolyte has the effect of suppressing the dissolution and precipitation of lead ions.

池のそれを１００とする比率で表した。Next, regarding a clad sealed lead-acid battery having a gel electrolyte containing 7% by weight of silica by mixing colloidal silica and dilute tiIIIts, prototype batteries were fabricated with various tube contents and the discharge performance was investigated. Initial, after 100H overcharging with 10HR current, and 50% charge/discharge with 60% discharge depth
After 0 cycles, the 5HR discharge capacity was determined and shown in Table 1. The capacity is expressed as a ratio of 100 to that of a battery using a normal tube.

同じ場合にはチューブの通水量が大きいほうが少なくて
好ましい。Table 1: Initially, there is not much difference in discharge capacity even if the electric resistance and water flow rate of the tube are significantly different, but after overcharging, especially after a charge/discharge cycle, a significant difference in capacity occurs. The decrease in capacity mainly depends on the electrical resistance of the tube, but when the electrical resistance is the same, it is preferable that the amount of water flowing through the tube is larger as it is smaller.
チューブは一般的には電気抵抗の小さなものほど通水量
が大きい傾向がある。しかし例えば編組式チューブでは
撚りを多くした糸を用いると糸そのものの多孔度が小さ
くなって通水量が同じでも電気抵抗は大きくなる。In general, the smaller the electrical resistance of a tube, the greater the amount of water that can pass through it. However, for example, in a braided tube, if a thread with a large number of twists is used, the porosity of the thread itself becomes small, and the electrical resistance increases even though the amount of water passing through is the same.
