法であった。Generation of separators, 'R solution, etc.! It consists of elements and a battery container that houses them. Part of assembling these batteries involves storing some or all of the power generation elements in a battery container that has been divided into a box and a lid, and then joining the divided battery containers together to integrate them. However, methods for joining these divided battery containers include a method of curing a liquid adhesive, a method of welding, and a method of using mechanical pressure welding. These bonding methods are selected depending on the shape of the battery and the need to maintain performance, but unlike welding methods, methods of curing liquid adhesives do not take measures against heat that is undesirable for battery performance. This method is advantageous in that it does not have the drawbacks of requiring mechanical pressure welding or that the shape of the joint portion is restricted, unlike methods using mechanical pressure welding.

３との組み合わせを選ぶ必要があることを意味する。[Problems to be Solved by the Invention] However, in the conventional method of curing and bonding liquid adhesives, the liquid adhesive before hardening rises along the wall surface of the battery container due to capillary action. There was a drawback to doing so. This will be explained below with reference to FIG. 2, which is an enlarged sectional view of a joint portion of a conventional battery container. As shown in FIG. 2, out of the pre-divided battery containers 1.2, the battery container 1 corresponding to the box housing the power generating element 5 and the battery container 2 corresponding to the lid are attached using liquid adhesive 3. At the time of bonding, the liquid adhesive 3 before hardening forms a gas-liquid-solid three-phase interface having a contact angle θ at a portion 4 where the liquid surface and the battery container 1 are in contact. In order to join the battery containers 1 and 2, it is necessary that the walls of the battery containers 1 and 2 be sufficiently wetted by the liquid adhesive 3 before hardening.
In other words, it is necessary to select a combination of battery containers 1 and 2 and liquid adhesive 3 made of materials in which the contact angle θ is smaller than 90'.

容積効率が低下してしまうという不都合が生じる。However, in such a case, since the contact angle θ is smaller than 90°, the position of the portion 4 where the battery container 1 and the liquid surface of the liquid adhesive 3 are in contact is at the meniscus 6 of the liquid adhesive 3 before hardening. It will always be higher than that. Therefore, when the distance intersection 1 between the meniscus 6 of the liquid adhesive 3 before hardening and the power generation element 5 is small, the portion 4 where the liquid surface of the liquid adhesive 3 and the battery container 1 are in contact with the power generation element 5 reached and power generation element 5
Among them, the liquid adhesive 3 before hardening may be sucked up and absorbed by porous electrode plates and separators. When this happens, not only the amount of liquid adhesive 3 decreases, but also the 1 m capacity of the power generating element in the portion that has absorbed the liquid adhesive 3 is impaired, which is a serious problem. To avoid such inconvenience,
When the distance 2 between the power generation element 5 and the portion 4 where the liquid surface of the liquid adhesive 3 contacts the battery container 1 is sufficiently increased, the distance between the meniscus 6 of the liquid adhesive 3 and the power generation element 5 becomes This increases the size of the battery, resulting in wasted space within the battery, resulting in a disadvantage that the volumetric efficiency of the battery decreases.

On the other hand, the above-mentioned problems are solved by having an inclination angle smaller than the contact angle of the liquid adhesive.

非常に長くする必要が生ずる。[Function] Next, the function of the present invention will be described below with reference to FIG. 1, which is an enlarged sectional view of a joint portion of a battery container showing one embodiment of the present invention. The part of the wall surface of the battery container 1 that comes into contact with the surface of the liquid adhesive 3 before hardening is constituted by an inclined part having an inclination angle θ smaller than the contact angle θ of the liquid adhesive 3 with respect to the horizontal plane. Therefore, the part 4 where the battery container 1 and the liquid surface of the liquid adhesive 3 before curing is always lower than the meniscus 6 of the liquid adhesive 3. Since the portion 4 in contact with the liquid surface of the adhesive 3 no longer reaches the power generation element 5°, it is possible to reduce the distance M1 between the meniscus 6 of the liquid adhesive 3 before curing and the power generation element 5. This eliminates wasted space within the battery and increases the volumetric efficiency of the battery.In principle, the inclination angle θ' is within the range from 0 to the contact angle θ of the liquid adhesive 3. It can be selected freely, but if the position of the part 4 where the surface of the liquid adhesive 3 before curing and the battery container 1 is in contact is lower than the meniscus 6 of the liquid adhesive before curing, the original purpose will not be achieved. Therefore, even if the inclination angle θ' is close to the contact angle θ of the liquid adhesive, it can sufficiently perform its function.On the other hand, if the inclination angle θ' is close to the contact angle θ of the liquid adhesive, , the slope of the wall of the battery container 1 and the liquid adhesive 3
In order to ensure reliable contact with the liquid surface of the battery container 1, it is necessary to make the sloped part of the battery container 1 very long.

法を前記本発明実施例と同一にしたものを製作した。As an embodiment of the present invention, a battery container 1.2 having the joint shown in FIG. A seal type in which an epoxy adhesive having a contact angle θ of 30° is used, and the wall portion of the battery container 1 in contact with the liquid surface of the liquid adhesive 3 is an inclined portion having an inclination angle θ′ of 30′ with respect to the horizontal plane. We manufactured a lead-acid battery.The external dimensions of the battery are 200m+n in length and 60m in height.
11111. The thickness is 25mm, and there are 6 batteries inside.
It consists of half cells connected in series. For comparison, a conventional sealed lead-acid battery has a joint shown in FIG. 2 without an inclined part on the wall surface of the battery container 1, and has other materials, configurations, and characteristics other than the size of the power generation element. A device with the same external dimensions as the embodiment of the present invention was manufactured.

The table below shows the discharge capacity when constant current and constant voltage charging at a voltage of 4.7 V was performed and discharge was performed at a current rate of 20 hours at an ambient temperature of 20°C.

した。As is clear from the table above, the product of the present invention has a 1% improvement over the conventional product.
0% volume was large. This is because in the product of the present invention, the uncured liquid adhesive does not rise along the wall of the battery container, so the size of the power generation element can be increased without creating wasted space inside the battery, whereas in the conventional product, the size of the power generation element can be increased without wasting space inside the battery. This is because the power generating element was made smaller in order to take up sufficient space, as the liquid adhesive before curing rises along the wall surface of the battery container in the battery case. In addition, if the size of the Ti generating element in the conventional product is the same as that of the product of the present invention, the liquid adhesive will rise along the wall of the battery container and reach the generating F and L elements, and the function of the generating element will be impaired. It was confirmed through experiments that the liquid adhesive was damaged and the capacity decreased.

You can get batteries.
