防ＩＩ：、するようにしたものが知られている。Conventionally, this type of sealed lead-acid battery, as shown in Figure 3, consists of a group of electrode plates (+ )
is housed in the battery case (2), and a flat splash-proof paper (3) is attached near the end opening (2a) of the battery case (2). ) to benefit (
5) is bonded and fixed, and the splash-proof paper (3) is arranged below the exhaust port (6) which also serves as an electrolyte injection port (1-1), which is transparently provided in the top surface (5a) of the lid (5). In this way, the adhesion of the electrolyte to the injection 11 (exhaust IJ) (G) or overflow from the injection 1'' (6) during chemical formation is prevented by the splash-proof paper (3). It has been known.

Concentric inner and outer peripheral walls (

槽化成法が一＋’流を占めるに至っている。In a sealed lead-acid battery with such a configuration, electrolyte is injected through the exhaust gas +1 (G) of the lid (5), and then chemical formation is carried out at 1, which is equipped with a safety valve.However, the current chemical formation method is The positive and negative electrode plates are both unformed and placed in a battery case (2
), or only the negative electrode plate is assembled as an unformed plate, and the so-called battery tank formation method, in which the formation is carried out in the battery case (2), has become the most popular method.

る。When carrying out this container chemical formation method, in order to sufficiently chemically form an unformed electrode plate, electricity M of about 6 to 7 times the theoretical amount of electricity per weight of active material is required. Therefore, considering the amount of water lost due to electrolysis during chemical formation, it is necessary to inject a low specific gravity electrolyte at a ratio of 1:1, but a large amount of electrolyte must be injected into the limited volume of the tank. When injected, the liquid level will rise by L and become very close to the inlet 11 (exhaust port) (5).

）から溢出するのを防＋ｌする。By the way, when chemical formation is carried out by the container chemical formation method in a battery with the above-mentioned conventional configuration, as shown in Fig. 4, when the chemical formation of the positive and negative electrode plates progresses and the voltage increases by 1, the electrolysis of the electrolyte becomes active. Oxygen gas and hydrogen gas begin to be generated from the electrode plate group (1). At this time, the separator is made of glass fiber with little internal voids, and both ends of the l-1 are surrounded by electrode plates, so gas passes through it slowly. Therefore, the apparent volume of the electrolyte increases, and the battery cell (2) The liquid level (L
) rises to the liquid level (L), and the gas generated rises to the liquid level (L) to form bubbles, and when these bubbles burst, the force of the electrolyte flows into the container (2) or the lid ( 5) and is pushed out by the gas. The splash-proof paper (3) prevents electrolyte droplets from adhering to the exhaust [1 (Ei)
) Prevents overflow from +l.

−策として充分とはいえないという問題点があった。However, in the case of the splash-proof paper (3) in the following example I, although it is possible to prevent the generated gas from going directly to the exhaust rT1 (G), Since the adhesive does not cover the embedded annular space (7), it stays in this annular space (7) and creates even larger bubbles (

When this bubble (8) grows large in the annular space (7), it causes the liquid level -1-'jl, and when the large bubbles that cannot be stored in the space come out to the liquid surface (L), the liquid level (L ) ,,lr, and electrolyte droplets are formed on the exhaust λIN(lli)? 1. To prevent electrolyte from adhering to the exhaust LLI (G),

不足して気密不良を引き起こす虞れがあった。Also, in the past, when attaching the splash-proof paper (3) to the L part of the battery case (2), it was necessary to attach the battery case (2) and the cover (5) upside down.
In order to harden the adhesive (4), if the flat splash-proof paper (3) falls on the side of the product (5), or if it falls, apply the adhesive (4) to the adhesive (4).
In some cases, the adhesive (4) may get stuck and fixed and cannot be installed in the correct position, or in some cases, the adhesive (4) may drop into the adhesive embedding annular space (7) and absorb the adhesive (4). ), there was a risk of a lack of airtightness.
更に、接着剤（４）は高粘度なため、極板群（１）の挿

排気［コ（６）を塞いでしまう虞れもあった。Furthermore, since the adhesive (4) has a high viscosity, the adhesive (4) overflows to the inside of the lid (5) when the electrode group (1) is inserted.
There was also a risk that the exhaust gas (6) would be blocked.

The purpose of this invention is to reduce the number of devices and to reduce the installation height from the liquid surface of the device, thereby making it possible to downsize the device.

特徴とするものである。Splash-proof paper is placed on the lid side, which is bonded and fixed over the end opening, to prevent the electrolyte from spilling out in the container during chemical formation.
This splash-proof paper is transparently provided on the large surface of the lid, and is characterized in that it is formed into a V-shaped or hemispherical cross-section so as to enclose the 1 air 11.

必要もなく、電池の小型化が可能になる。In the present invention, according to the configuration described in 1-, the bubbles of oxygen gas and hydrogen gas generated during chemical formation reach the liquid surface of the electrolyte and burst, and the electrolyte droplets scattered by the force can be scattered in any direction. , all of them just adhere to the outer peripheral surface of the splash-proof paper formed in a V-shaped or hemispherical cross-section, and do not reach the υF air 1-1 wrapped in this splash-proof paper. Therefore, there is no overflow or adhesion of electrolyte droplets from the exhaust port, so the step of wiping off the overflow can be omitted, and even if the lid is installed at a height close to the highest liquid level, there is no risk of electrolyte overflowing. Since there is no
There is no need to provide a height space at the liquid level +1 to prevent overflow of electrolyte droplets, and the battery can be made smaller.

When oxygen gas and hydrogen gas are generated, these gases are separated on both sides of the V-shaped splash-proof paper (13) and distributed to I-'9'i'.
L, the liquid level (Lo) directly below the exhaust D (IG) is covered with splash-proof paper (
13) prevents me from going up -1-. In addition, when the gas stagnant in the adhesive-embedded annular space (+7) comes out to the liquid level (Lo), the bubbles hit the negative side of the V-shaped splash-proof paper (+3) and flow into the inside of the splash-proof paper (+3). Intrusion is blocked by +L. Therefore, υ [ki n
(16) All the bubbles (18) do not enter the liquid level (Lo) just below, and the electrolyte adheres to the exhaust port (16) due to the bursting of the bubbles (18) and exhausts ['1 (IG ) This will definitely prevent you from getting out of the bath.

When we prepared 00 batteries, chemically formed each of these batteries at the same time, and conducted a hot liquid investigation of the electrolyte, we found that 48 batteries (24%
), there was so much hot liquid that it was necessary to wipe the area around the exhaust port, whereas in the case of the structure of the present invention, there was no such liquid at all.

る。As explained above, when using the sealed lead-acid battery of the present invention, the lid, which is bonded and fixed over the top opening of the battery case, is provided with a lid to prevent the electrolyte in the battery case from leaking out during chemical formation. The exhaust air vent is equipped with splash-proof paper, and this splash-proof paper is transparent on the top of the lid.
Since it is formed into a V-shaped cane or hemispherical cross section so as to envelop 1, even if the gas bubbles generated during chemical formation rupture at the surface of the electrolyte, the electrolyte will scatter in any direction. The splash-proof paper, all of which has a V-shaped cross section or a spherical shape, prevents air from adhering to the air and from exiting the bath during exhaust, thereby preventing the wiping of the bath liquid. By omitting the culm, the number of batteries can be reduced.42.The height space for preventing electrolyte splashes from coming out on the liquid surface can be omitted, making it possible to downsize the battery. .
