ま見ら扛る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lithium-oxyhalide battery that uses lithium as a negative electrode active material and oxyride as a positive electrode active material. 0 The so-called oxyno-1 rides used in lithium-oxyno-ride batteries, such as thionyl chloride, sulfuryl chloride, and phosphorus oxychloride, are liquids that serve as the positive electrode active material and the electrolyte solvent in these batteries. It is. These oxyhalide vapors are not toxic to the human body, but are hydrolyzed by moisture in the air and are highly corrosive to metals. Therefore, injecting an electrolyte containing oxyhalide as a solvent into a battery is generally carried out in an atmosphere with almost no moisture, and the holes provided for the injection are designed to prevent moisture from entering the battery can. Therefore, it must be completely sealed. Conventionally, there are two types of injection ports for this type of battery can: a pipe that also serves as a terminal, and a hole that is cut directly into the battery can.The former is made by crushing the pipe opening, and the latter is made of metal. The latter type of injection port is used in most flat batteries where the length of the pipe is not allowable due to dimensions. This shape, in which the battery can is in direct contact with the electrodes inside the can, makes it difficult to perform post-processing that applies heat, such as crushing the opening of the pipe and then welding this part, as seen in the former case, so it is difficult to seal it completely. I keep seeing cases where I haven't done so.

ある。The present invention aims to eliminate the above-mentioned drawbacks, and aims to improve the reliability of airtightness after sealing by changing the shape of the injection port directly provided on the battery can from the conventional one.
本発明の実施例を図面によって説明する。Embodiments of the present invention will be described with reference to the drawings.

図も上が電池缶の外側、下が電池缶内部になっている。FIGS. 2 and 3 are diagrams of the state in which the liquid injection port according to the present invention is sealed by making a hole in the battery can and then making a shallow hole on the outside of the can.
' is a part of the can, 2 is a conical metal stopper with a flange fa at the upper end, and a liquid injection port. In the illustrations of Figures 1 to 3, the top is the outside of the battery can, and the bottom is the inside of the battery can.

が従来よシも深くなって気密が完全となる。Inlet port 3 or 3 shown in Fig. 1, Fig. 2, and Fig. 3
When sealing is done by pushing a metal stopper 2 or 2' into the battery case, the airtightness inside the battery can is mainly maintained at point A on the inlet side of the liquid injection port 3 in conventional batteries, as shown in FIG. Since the liquid injection port 3' according to the present invention is constricted in the opposite direction to the direction in which the stopper 2 or 2' is pushed in, the can and the stopper 2 or 2' for Japan at the contact point A' on the back side shown in FIGS. The bite of C2' is deeper than before, making the airtightness perfect.

大である。In addition, the collar 2/a provided on the stopper 2' shown in FIG. In addition to improving the reliability of the airtightness of the Δ sealing part of the battery injection port, the problem is that the battery can is damaged due to the plug being pushed in too much when trying to deepen the engagement between the can and the plug at contact point A. This is of great industrial value, as it can reduce defects such as deformation.
