着部が残りや丁い現象力を認められる。- At the crotch, - part (- When the Jitsukiji sheets are heated together with a metal plate in between, there is a large heat loss in the metal plate part because metal is a good conductor of heat, and the resin sheet vav The rise is insufficient for welding to the metal plate, and the cross-sectional shape of gold and @ plates varies industrially. Wealth 1: The cross-sectional shape of the hot melting jig must be made to match exactly. However, the piezoelectric force becomes uneven, and unwelded areas remain at the boundary between the metal plate and the resin sheet, and a bending force is observed.

設置できて電池の容積効率が向上する。Since the entire working electrode plate group, including the pole part, is housed in the battery case, the battery case is sealed by gluing the resin sheets together. I: Comparatively, the work of adhering to the mounting lid is easier, the adhesive part is more reliable, and waxing of the electrolyte does not occur. Because it is installed through a through hole in the tank body,
There are no restrictions on the shape of the pole part, and the terminal part can also be installed within the thickness of the battery, improving the volumetric efficiency of the battery.

。To seal the through hole, drop or press fit the molten synthetic rubber material into the hole part 1. The plate-shaped synthetic resin plate is used as a protective plate to prevent an escape cut from entering the back side of the battery case when a cutout that serves as an electrolyte injection port and a safety valve is provided in the battery case. It also works to maintain the flatness around the notch and stabilize the operation of the safety valve.A very thin water film is formed at the interface between this resin plate and the battery case due to moisture brought from the electrolyte. This exhibits a backing effect and a glue effect, maintaining good airtightness no matter what position the battery is held in.

業が容易となり生産性が向上する。When the pressure inside the battery becomes higher than the outside pressure due to excessive photovoltage of the battery, the battery case swells, causing the resin plate and the battery case interface to separate and gas to be released through the notch. After the gas is released, the elasticity of the battery case material 1: Due to the restoring force, the resin plate (2-close guard to maintain airtightness, and when you want to demonstrate its operation as a safety valve, turn over the resin sheet of the battery case) This also improves the alignment of the injection tube, making it easier to inject the electrolyte and improving productivity.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.

８の溶戯物を滴下し、固化させて貫通穴部を封止した。Example 1 As shown in FIG. 1, a chemically formed positive electrode plate 's6 and negative electrode plate (
Electrode plate group 1 consists of one glass mat separator (length 85 mtr x width 451 mtr x thickness 1.5 mtr) and a glass mat separator with a thickness of 0.5 mtr.
One 5 m long ABS resin flat plate 2 is sandwiched between two resin sheets 3 made of a composite of 0.1 thick polypropylene/vinylidene chloride, which has acid resistance, heat weldability, and flexibility, and then this is made into an electrode plate. A container body made of a resin sheet was formed along the periphery 1 of the group with a width of 2 m by heat welding using a heat press machine and sealed with a heat melt seal 4. At this point, the entire electrode plate group including the pole column portion 5 is sealed inside the battery case. Next, use a punch-like cutter to make a through hole 6 in a part of the resin sheet on one side of the resin sheet in contact with the pole pillars provided on the positive electrode plate 3 and the negative electrode plate, and use a punch-like cutter to make a through hole 6 through this part as a conductive wire 7 for electric charge ratio. A .75 m copper wire was connected to the pole section by soldering. Thereafter, a melt of a sealing body 8 made of synthetic rubber that adheres well to the metal 2 and resin was dropped into the hole and solidified to seal the through hole.

重ではがれることはなく、良好な密着性を示した。Next, a notch 9 was made with a sharp knife in a part of the resin sheet on one side of the part in contact with the MuBSm fat plate, and an electrolyte injection tube was inserted through this part. A predetermined amount of dilute sulfuric acid was injected, and this was absorbed and retained by the separator and electrode plate. After injecting the electrolyte, when the injection tube is pulled out, the resin sheet around the notch often complains to the resin plate due to the restoring force due to the flexibility of the resin sheet, and the moisture brought from the electrolyte causes the bond between the resin plate and the resin sheet. A water film was formed at the interface. This water film is extremely thin and has a backing effect and a dramatic effect, preventing outside air from entering the battery case. No matter what position it was held in, it did not peel off under its own weight and showed good adhesion.

気密性を保った。above! When a photodischarge cycle life test was conducted using a closed lead storage battery, good results were obtained with an average life of over 150 cycles. There is no difference in the above performance even if the posture in which the battery is held and lowered is changed, and the airtightness of the notch is good.
Indicated. When the pressure increases due to excessive photoelectricity, the notch opens and acts effectively as a safety valve, and when the pressure decreases, it closes and maintains good airtightness.

トを用いた。2. It is preferable to make the resin sheet material of the battery case thinner because it can improve the adhesion with the resin plate at the notch, but if it is made thinner, the phenomenon of moisture permeation and oxygen permeation through the resin sheet becomes noticeable. , electrolyte depletion and abnormal oxidation of the electrode plates occur, shortening battery life. In such cases, if you select a resin material that is moisture permeable and oxygen permeable, and use these as a thin layer sheet, you can achieve great performance with the same thickness.
It has become clear that extending the service life is effective, and here we used a commercial resin sheet made by dipping pyripropylene and vinylidene chloride.

In addition, a safety valve with good performance can be easily formed, and injection of electrolyte is also easy.

象が皆無となり、貫通穴部の封止の信頼性が高まった。Example 2 The wood structure of the battery is the same as in Case 1, and the poles, conductors for electricity extraction, wire connections and their surroundings are made of epoxy resin that has good adhesion to metals and good acid resistance. After soaking, the correspondence hole was sealed with synthetic rubber. As a result, the phenomenon of electrolyte creeping up from the interface between the conductor and the synthetic rubber, which was sometimes observed at the end of the charge/discharge cycle test without this resin coating, has completely disappeared, and the reliability of sealing the through hole has been improved. It has increased.

できた。Example 3 The basic structure of the battery was the same as in Example 1, and after the through holes were sealed with synthetic rubber, the surface of the synthetic rubber portion was covered with epoxy resin. As a result, synthetic rubber is flexible and sticky due to its characteristics, so the electrical lead wire or terminal may move slightly while handling the battery, causing safety concerns, and if the sealed part is touched with the hand. However, the epoxy resin coating can strengthen the sealing area, reducing the anxiety and discomfort during handling. I was able to resolve it.

きた。Example 4 The basic structure of the battery was the same as that of Example flJ1, and the resin sheet 2 and the resin sheet of the battery case in contact with it were heat welded, leaving a portion surrounding the notch 9, as shown in FIG. The safety valve thermal osteolysis zone]0 was formed. As a result, the adhesion between the resin plate and the resin sheet attached to it increases the tree pressure around the notch, and the operating pressure when gas is exhausted from the notch becomes constant, improving the reliability of the battery. I could do the same.

It was fixed to the resin sheet of the battery case by heat welding, leaving an undissolved bone part in the area. As a result, the trace amount of sulfuric acid gas emitted when gas is exhausted from the notch is absorbed into the neutralizing material.
The neutralized gas discharged from the undissolved bone region did not contain sulfuric acid, making it possible to prevent equipment using the battery of the present invention from being contaminated and corroded by the 4A acid.
