Description
【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。Description: FIELD OF THE INVENTION 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、負極板及び
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高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 Regarding the life performance of lead-acid batteries, as is well known, the electrode group composed of the positive electrode plate, the negative electrode plate, and the separators between both electrode plates, and the electrode group composed of the glass mat is pressed at a higher pressure than both side surfaces. And significantly improved.

供用されている。In conventional assembly, a pre-calculated pole group thickness is inserted into a battery case designed to be a little narrower than that, or it is made of acid-resistant synthetic resin or a pulp fiber board or plastic called a occlusive board. Spacers are arranged on both side surfaces and inserted into a battery case to obtain a predetermined tightening pressure.

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。As another method for applying a compressive force to the pole group, a method has been proposed in which the pole group in a state where the spacers are in contact is wrapped with a heat-shrinkable tape. However, in this case, the compression force required to maintain the life of the lead storage battery cannot be sufficiently obtained. In addition, there are drawbacks that the creep resistance is poor and the pressure of the pole group during use is largely reduced. Furthermore, since the heat-shrinkable tape has a small breaking strength per unit area, it is necessary to wind the heat-shrinkable tape so as to cover the entire surface of the pole group. This hinders the use of the electrolytic solution around the pole group, and there is also a drawback that the capacity is difficult to obtain particularly in a liquid type lead storage battery.
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 pole group by band binding,
The problem was how the band material maintained and maintained the initial high tension until the end of its life.

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。The elongation at break of conventional polypropylene resin is 20%
Met. These are the force to maintain the initial tension, the repulsive force against the tension applied to the pole group, the volume expansion accompanying the charging and discharging of the positive electrode active material, and the accompanying growth of the positive electrode lattice body. This is because the combined force concentrates on the band. Therefore, there is a drawback in that the band is constantly subjected to creep and a high tension cannot be maintained until the end of its life, which shortens the life of the lead storage battery.
発明の目的 本発明は上記従来の欠点に鑑みなされたものであり、寿

た。A plastic rib plate is applied to both sides of the positive electrode plate, the separator, the glass mat, and the negative electrode plate. At this time, in order to prevent both sides of the pole group from being covered with the rib plates and coming out of contact with the electrolytic solution, openings are provided in the rib plates. Further, the height of the ribs 4b is formed so that the ribs on the center side are higher than the ribs on both sides of the end side of the rib plate 4. Next, the rib plate and the pole group are tightly bound with a band capable of heat welding. The band was embossed, and a white additive such as magnesium silicate or magnesium carbonate was added as a filler to suppress the elongation of polypropylene. Here, talc powder was used as the filler, but if the added amount is less than 5%, the effect on elongation is small. If the amount added is more than 20%, it is unsuitable because it deteriorates the heat-welding property between the bands. The effective amount of talc powder added is in the range of 5 to 20%. Also, those obtained by arranging a long glass fiber woven fabric on the center surface during band molding, or a band breaking strength of 50 to 8 after molding.
A band that has been stretched at a strength of 0% is used. In all cases, the breaking elongation of the band was 2% or less.

られる。In addition, the pole group was formed into a shape approximately similar to a circle, and a pressure of 0.5 kg per cm 2 of the pole plate was applied from both side surfaces during assembly. Sulfuric acid 6 having a specific gravity of 1.26 was injected into each of the obtained batteries and subjected to a cycle test. The results are shown in FIG. The battery of the present invention has remarkably excellent life characteristics. The reason for this is
In the lead acid battery according to the present invention, the thickness of the pole group hardly changes even when the charge / discharge cycle proceeds. The lead group of lead acid batteries using conventional polypropylene resin band has a volume expansion of the positive and negative electrode active materials due to alternating charge and discharge and a separator or glass incorporated between the electrode plates even if they are tightened with a high compression force at the beginning. It is considered that the repulsive force of the mat gradually relaxes, and as a result, the compressive force on the pole group gradually decreases and the battery life is shortened.
