【発明の詳細な説明】 産業上の利用分野 本発明は鉛蓄電池の改良に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to improvements in lead-acid batteries.
従来技術とその問題点
鉛蓄電池の寿命性能は、周知の如く正極板、電極板及び
両極板間に配したセパレータ、ガラスマットにより構成
された極群に両側面部より適度な高圧力で圧迫を加える
と著しく向上する。Conventional technology and its problems As is well known, the life performance of lead-acid batteries is determined by applying moderately high pressure from both sides to the electrode group, which is made up of a positive electrode plate, a separator placed between the electrode plates, and a glass mat. and significantly improved.

供用されている。In conventional assembly, a material with a pre-calculated extremely detailed thickness is inserted into a container designed to be slightly narrower, or an acid-resistant synthetic resin, a pulp fiber board called a cuff board, or a plastic ring is used. Spacers are placed on both sides of the battery and are designed to be inserted into the battery case to obtain the specified pressure.

分に得られない。又、耐クリープ性が劣り、使用中の極
群圧迫力の低下が大きいという欠点があった。As another method of applying compressive force to the pole group, a method has been proposed in which the pole group with the spacer in contact is covered with heat-shrinkable tape. However, in this case, the compressive force required to maintain the life of the lead-acid battery cannot be sufficiently obtained. In addition, they had the disadvantage of poor creep resistance and a large drop in polar group compression force during use.
さらに熱収縮性テープは、単位面積当りの破断強度が小
さいので、極群全面を覆うように捲く必要がある。この
ことは、極群周辺の電解液利用を妨げることとなり、特
に液式の鉛蓄電池では容量が出にくいという欠点も生じ
る。Furthermore, since the heat-shrinkable tape has a low breaking strength per unit area, it is necessary to wrap it so as to cover the entire surface of the pole group. This hinders the use of the electrolyte around the electrode group, which also causes the disadvantage that it is difficult to achieve capacity, especially in liquid lead-acid batteries.
ところで、バンド緊縛による極群の緊圧維持において、
バンド材質が寿命末期まで初期の高い緊圧をいかに維持
持続するかが問題であった。By the way, in maintaining the tightness of the extreme group by band bondage,
The problem was how to maintain the initial high tension of the band material until the end of its life.

ためである。その為に、常時バンドにクリープが加わり
、寿命末期まで高い緊圧力が維持できない状態であり、
鉛蓄電池の寿命が短くなる欠点がある。Conventional polypropylene resins have an elongation of about 20 at break. This is due to the force that maintains the initial tension, the repulsive force against the tension pressure applied to the electrode group, the volume expansion accompanying charging and discharging of the positive electrode active material, the accompanying grease on the positive electrode grid, etc. This is because the combined force is concentrated on the band. For this reason, creep is constantly added to the band, making it impossible to maintain high tension until the end of its life.
The disadvantage of lead-acid batteries is that their lifespan is shortened.

Bind the lip plate and the pole group with a band that can be heat welded. The band is
It is embossed, and a white additive such as magnesium silicate or magnesium carbonate is added as a filler to suppress the elongation of the polypropylene. Here, talcum powder was used as a filler, but if the amount added is less than 5%, the effect on elongation will be small. The amount added is 20
If it is larger than %, it is unsuitable because it lowers the heat weldability between the pans Y. It is effective to add talcum powder in an amount of 5 to 20%. Alternatively, a fabric made of long glass fibers may be used as a paste and placed on the center surface during band molding, or a band may be stretchable with a strength of 50 to 80% of the band breaking strength after molding. In all cases, the elongation at break of the band was 2% or less.

と考えられる。The electrode group was shaped to have a substantially circular shape, and a pressure of o.sh was applied to each electrode plate from both sides during assembly. Sulfuric acid 61 having a specific gravity of 1.26 was injected into each of the obtained batteries and subjected to cycle test F. Figure 2 shows the results. The battery of the present invention has extremely excellent life characteristics. The reason for this is that in the lead-acid battery according to the present invention, the thickness of the electrode group hardly changes even as charge/discharge cycles progress. Even if the electrode group of a lead-acid battery using a conventional propylene resin band is initially tightened with high pressure, the volume expansion of the positive and negative electrode active materials due to alternate charging and discharging, and the aging of the pallet inserted between the electrode plates occur. It is thought that the repulsive force of the glass mat gradually loosens it, and as a result, the pressure on the electrode group gradually decreases, shortening the battery life.
