るものである。In FIG. 1, a solid electrolyte tube 1 is made of β'-alumina with an open upper part, an outer diameter of about 45 mm, an inner diameter of about 38 mm, and a length of about 400 mm.

On the upper surface of this a-a A/l nut ring 2 is a cathode made of aluminum coated iron or stainless steel! 5 is thermo-pressure bonded, and the bottom surface has an anode made of the same material!
4 are thermo-pressure bonded. This l&[l! 4 is welded with an anode auxiliary lid 4'. In the solid electrolyte tube 1, a metal fiber 12 made of 7-metal stainless steel is wound so as to provide a center hole and housed in the solid electrolyte tube 1 to form a cathode chamber. On the other hand, a cathode current collector container 13 having an inwardly directed convex portion 15B on a part of the side surface, a hole 14 and an upwardly directed protrusion 15B on the bottom surface is prepared, and the upper part of this cathode current collector container 13 is , is welded to the inner peripheral edge of the cathode lid 3 so that its bottom surface contacts the metal fiber 12. Note that the cathode current collector container 13
A stepped portion 15' is provided on the bottom surface to form two stages, and the bottom surface of the lower step is provided with a hole 14 and a protrusion 15B facing upward. The hole 14 and the protrusion 15B can be easily formed by making a V-shaped cut in the bottom surface of the cathode current collector container 13 and directing the cut portion upward. Furthermore, the convex portions 15 can be easily formed by uniformly pressing the cathode current collector container 13 from the outer peripheral surface thereof. Next, as shown in FIG. 2(a), an O-ring 16 is placed on the step 13' of the cathode current collector container 13, a sodium tank 17 filled with sodium 8 is placed above it, and the hole is heated under heating. After evacuating the cathode chamber through 14, (4) hold the V-ram tank 1 frame with the protrusion 15, and pierce the sodium tank 17 with the protrusion 15B to vacuum-fill the cathode chamber with sodium 8; 2) is a diagram showing a state in the middle of filling the sodium 8. After cooling, the sodium tank 17 and O-ring 16 are removed, and the cathode current collector container 1 is removed.
A cathode terminal 5' is welded to the upper inner peripheral edge of the cathode chamber 5 to form a cathode chamber structure. On the other hand, a battery case 9 into which a cylindrical sulfur molded body 10 has been inserted is prepared, and after inserting the cathode chamber structure into the central hollow part of this sulfur molded body 10, the anode auxiliary lid 4' and the battery case 9 are The upper end of the battery is welded to seal the cathode chamber to complete the completed battery.

時に陰極室内の気密性の保持が容易になる。Margin Table-1 Table-1 shows that when conventional batteries are damaged, the active material leaks out, and all of them are internally short-circuited. There was no leakage, and no internal short circuit was observed. Because of the manufacturing method described above, sodium does not adhere to the tip of the cathode terminal 5', and welding defects due to this can be prevented. Furthermore, since there is no need to provide a connecting pipe at the tip of the cathode terminal 5 during filling, the time and number of parts required for filling can be reduced. Furthermore, since the sodium tank 17 can be held by the convex portion 155 provided on the cathode current collector container 13, it becomes easy to maintain airtightness within the cathode chamber when filling the sodium 8.

処することができる。Effects of the Invention As described in detail in the Examples, the battery of the present invention has good airtightness and thus has stable quality. Further, even if the battery is damaged, the lower part of the cathode current collector container 13 from the stepped portion is fused due to the heat of the direct reaction between sodium and sulfur, thereby preventing the occurrence of an internal short circuit. Furthermore, since this manufacturing method can reduce the time and parts required for filling with F, it can be adapted to mass production.

A cathode terminal is welded to the inner peripheral edge of the upper part of the container to form a cathode chamber structure.Meanwhile, a battery case into which a cylindrical sulfur molded body is inserted is prepared, and the cathode chamber is inserted into the hollow part in the center of this sulfur molded body. 1. A method for manufacturing a sodium-sulfur battery, comprising: inserting the component, and then welding the anode auxiliary lid and the upper end of the battery case to seal the anode chamber.
