INDUSTRIAL APPLICATION FIELD The present invention relates to sodium-sulfur batteries, and more particularly to the structure of thermopressure joints. Prior art and its problems A sodium-sulfur battery combines sodium as a cathode active material and sulfur as an anode active material in a β-
This is a high-temperature secondary battery with a completely sealed structure, separated by a sodium ion conductive solid electrolyte tube such as alumina or β''-alumina.The conventional structure of this sodium-sulfur battery is explained with reference to Fig. 3. .In Figure 3, 1 is a solid electrolyte and α
- the alumina ring 2 is glass-bonded to the solid electrolyte tube 1; Reference numeral 3 indicates an anode cover, and 4 indicates a cathode cover, which are bonded under heat and pressure to the lower and upper surfaces of the α-alumina ring 2, respectively, via an aluminum layer. 5 is a battery case,
Its upper end and anode cover 3 are welded. In a sodium-sulfur battery having the conventional structure as described above, when the anode cover 3 and the cathode cover 4 are hot-pressure bonded to the α-alumina ring 2, the anode cover 3 and the cathode cover 4 are placed eccentrically in the upper and lower pressure jigs, or At times, they tend to shift laterally, resulting in poor airtightness at the joints, and because they operate at high temperatures, there is a risk that the active material may leak out due to increased internal pressure and cause a fire. Purpose of the invention This invention prevents airtightness from occurring by preventing the α-alumina ring from being placed eccentrically in the press jig when bonding the α-alumina ring, anode cover, and cathode cover by heat and pressure. Sodium, which is highly safe
The purpose is to provide sulfur batteries. Structure of the invention In the sodium-sulfur battery of the invention, a cathode lid and an anode lid are thermo-pressure bonded to the upper and lower surfaces of an α-alumina ring to which a solid electrolyte tube is glass-bonded, respectively. - At least the inner periphery of the surface opposite to the alumina ring and the lower surface of the cathode cover, that is, the surface opposite to the α-alumina ring, is raised upward. A heat-resistant metal ring with an upwardly rising portion is disposed and bonded under heat and pressure. Examples The following examples will be explained below. FIG. 1 is a sectional view of the sodium-sulfur battery of the present invention. In FIG. 1, an α-alumina ring 2 glass-bonded to a solid electrolyte tube 1 has a metal ring 6 on its bottom surface through an anode lid 3, and a metal ring 6' on its top surface through a cathode lid 4.
are disposed and are thermo-pressure bonded to the α-alumina ring 2 together with the anode cover 3 and the cathode cover 4, respectively. In the embodiment shown in FIG. 1, the metal rings 6, 6' have upper and lower rising portions 7, 7' on the inner and outer peripheral edges, respectively, as shown in the enlarged view of FIG. There is. The height h of the upper rising portion 7 of the inner peripheral edge of the metal ring 6 is set to be equal to or less than the thickness of the anode lid 3 to prevent eccentricity of the anode lid 3. It is also appropriate that the height h' of the lower rising portion 7' of the outer circumferential edge portion be set to such a level that a lower pressurizing jig (not shown) for thermo-pressure bonding can be inserted therein and lateral displacement will not occur. On the other hand, the upper rising portion 7 of the inner circumferential edge and the lower rising portion 7' of the outer circumferential edge of the metal ring 6' fix an upper pressurizing jig (not shown) to prevent eccentricity of the cathode cover 4. with α−
Alumina ring 2 is fixed. In the sodium-sulfur battery of the present invention having the above configuration, the metal rings 6, 6' are made of stainless steel with a wall thickness of 0.5 mm, and the height h of the upper rising part 7 of the inner peripheral edge is
The thickness of the anode cover 3 and cathode cover 4 is 0.4mm.
Ten batteries were manufactured using 0.5 mm steel coated with approximately 35 μm aluminum, and compared with 10 conventional batteries as shown in Figure 3, the results are shown in Table 1.

限定するものではない。[Table] Table 1 shows that in the conventional battery, various abnormalities occurred repeatedly, and some of them led to poor airtightness, whereas in the battery of the present invention, only one deformation of the cathode lid occurred. Moreover, it was a minor problem that did not result in poor airtightness. Effects of the Invention As described above, the present invention provides a metal ring having an upwardly rising portion with at least the inner peripheral edge rising upward on the upper surface of the cathode cover and the lower surface of the anode cover. By thermo-pressure bonding to the α-alumina ring through the bonding, the occurrence of poor airtightness due to eccentricity and lateral displacement is prevented, and the practical value of the sodium-sulfur battery is increased. In the present invention, the shape of the metal ring can be arbitrarily determined depending on the upper and lower pressure jigs, the thickness of the cathode lid, the anode lid, and the thickness of the α-alumina ring, and is not particularly limited.
