【Example】

 Hereinafter, an example of implementation of the battery according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing an upper part of a battery and an electrolytic solution container showing an example of an embodiment of the battery according to the present invention. In FIG. 1, the battery 1 is composed of the cells 2 (single cells), which are the main constituents of the battery 1, through the partition walls 1a as many as the capacity of the battery 1 (in this case, the number of connected 1 cell / 2 volt 6). Are formed in parallel by adjoining vertical arrangement. The lid 3 is attached to the upper opening surface of each cell 2. Inside the lid body 3, an injection port 4 which is a bottomed recess is provided.

As shown in FIGS. 2 and 3, the bottomed recessed injection port 4 has semicircular injection holes 4b, 4b formed in the bottom plate 4a with the bridge plate 4c interposed therebetween, and the bridge plate 4c. The opening projection 5 is integrally erected on the top. The unsealing projection 5 has an acute-angled rupture body 5a formed in the upper portion rising with the same width as the bridging plate 4c, and a substantially vertical ventilation hole 5b is bored inside. The breaker 5a of the unsealing projection 5 need not be the one shown in the figure as long as it is a shape that breaks through the seal 13 of the electrolytic solution container 10 described later. The upper surface of the ventilation hole 5b is located higher than the injection hole 4b.

With respect to the battery 1 having the above-described configuration, the electrolytic solution container 10 for pouring the electrolytic solution 12 into the battery 1 is formed of a resin material or the like, and each of the main containers 11 is a battery 1 The number of cells 2 (unit cells) in this example (the number of one cell and 6 pieces of 2 volts connected in this embodiment) is the same as that of each cell 2 and is integrally formed in a side-by-side distributed form. There is. In the lower part of the container 11, a spout 11a having a shape which is reduced in diameter from the main body side of the container 11 is formed by a projecting body parallel to the longitudinal direction of the container 11. Each tip of the liquid pouring port 11a is sealed after filling the inside of the container 11 with the electrolytic solution 12 to form a seal 13 and is configured as a whole electrolytic solution container 10.

In the battery 1 and the electrolytic solution container 10 configured as described above, the electrolytic solution 12 is introduced into each cell 2 of the battery 1 from the dispersion type electrolytic solution container 10 in which the electrolytic solution 12 is filled and sealed in advance in each container 11. In the case of injecting, the electrolyte solution container 10 is strongly pressed to the battery 1 side after being lightly fitted into the injection port 4 formed in the lid body 3 of the battery 1 with the injection port 11a of the container 11 facing downward. .. Then, the unsealing projection 5 provided upright on the bottom plate 4a of the injection port 4 pierces the seal 13 of the pouring port 11a in the electrolytic solution container 10, and the electrolytic solution 12 in the electrolytic solution container 10 is discharged from the pouring port 11a to the cell. It is injected into each cell 2 through the injection hole 4b of the injection port 4 of the No.

At this time, the air 6 and the electrolytic solution 12 cause the air 6 in each cell 2 to be discharged into the container 11 at a high position through the ventilation hole 5b of the opening protrusion 5. On the other hand, the electrolytic solution 12 in the container 11 corresponding to the discharged amount is pushed out downward from the spout 11a of the container 11, so that the electrolytic solution 12 is discharged to the short injection holes 4b and 4b. After that, it is poured into the cell 2 located directly below it. The replacement operation of the air 6 and the electrolytic solution 12 is simultaneously and surely performed in parallel, and the electrolytic solution 12 in each battery electrolytic solution container 10 is visually checked into the cell 2 immediately below at each position. It can be injected easily, accurately and at once without requiring.

In addition, in the operation of injecting the electrolytic solution 12 into the battery 1, the electrolytic solution container 10 can be opened at the same time as the electrolytic solution container 10 is connected to the battery 1. There is no inconvenience such as leakage during the connection operation, and the electrolytic solution 12 can be surely poured into the battery 1.

Further, the opening operation of the electrolytic solution 12 does not have to be performed for each liquid chamber of each electrolytic solution and for each cell 2, and not only can it be easily performed with one touch, but the opening operation can be performed by a person who operates for the first time. It can be easily understood that the unsealing projections for are simultaneously arranged in each battery 1, and the liquid injection operation can be performed easily.

Since the tip of the unsealing projection 5 in the embodiment is located below the upper portion of the battery lid, the end of each electrolytic solution container 10 is inserted into the liquid injection port 4 of each cell 2 of the battery 1. Only when it is inserted, the breaker 5a of the opening projection 5 makes a hole in the seal 13 of the electrolytic solution container 10 and the opening projection 5 does not hit other parts, so that it does not become an obstacle. ..

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. When injecting the electrolyte into the battery, it is only necessary to press this electrolyte container on the battery side, so no tools or cutting operations are required, and the operation of injecting the battery can be performed efficiently. it can.

In the operation of injecting the electrolytic solution into the battery, when the electrolytic solution container is connected to the battery, the electrolytic solution container can be opened at the same time, which causes the inconvenience that the electrolytic solution leaks during the connecting operation. Without, it is possible to surely inject the electrolytic solution into the battery.

Since the ventilation hole is formed in the unsealing protrusion, not only can the solution be injected while the electrolytic solution container is still in the opening operation, but the air can effectively enter the electrolytic solution container. Even a small battery with a small injection port will not interfere with the injection, and the battery can be made smaller.

It is not necessary to perform the opening operation of the electrolyte solution for each cell of each electrolyte solution and for each cell, and it is possible not only to perform it easily with one touch, but also to open the opening hole for the first person to operate. It is easy to understand that the same number of protrusions are arranged on each battery, and the liquid injection operation can be performed easily.
