INDUSTRIAL APPLICATION FIELD The present invention relates to a sodium-sulfur battery, and more particularly to the structure of an anode lid bonded to an α-alumina ring by thermopressure. 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 Figure 2. .In Fig. 2, 1 is a solid electrolyte tube with α
- glass bonded to the solid electrolyte tube 1 to the alumina ring 2; 3 is an anode cover, and 4 is an anode cover, which are bonded to the lower and upper surfaces of the α-alumina ring 2 by thermopressure via an aluminum layer, respectively. 5 is a battery case,
Its upper end and anode cover 3 are welded. In a sodium-sulfur battery with the conventional structure as described above, the anode cover 3 and the α-alumina ring 2 are eccentrically joined by thermo-pressure, and the joint width is partially narrow, resulting in poor airtightness of the joint. Because they operate at high temperatures, there is a risk that the active material may leak out due to an increase in internal pressure and cause a fire. Purpose of the invention This invention prevents the occurrence of airtightness by preventing eccentricity of the anode cover and the battery case welded to the anode cover with respect to the solid electrolyte tube and the α-alumina ring glass-bonded to the solid electrolyte tube. The purpose is to provide a highly safe sodium-sulfur battery. Structure of the invention In the sodium-sulfur battery of the invention, a step is provided on the anode cover that is thermo-pressure bonded to the lower surface of the α-alumina ring, and the vertical surface of the step is brought close to the outer peripheral surface of the α-alumina ring. , is maintained. Examples The following examples will be explained below. FIG. 1 is a sectional view of the main parts of the sodium-sulfur battery of the present invention. 1st
In the figure, α is glass-bonded to solid electrolyte tube 1.
- Bringing the outer circumferential surface 2' of the alumina ring 2 and the vertical surface 3' of the stepped part of the anode lid 3 provided with the stepped part into close proximity;
Eccentricity of the α-alumina ring 2 and the anode cover 3 with respect to the solid electrolyte tube is prevented. Now, in Fig. 1, the stainless steel anode cover 3 is made so that the inner diameters R 1 , R 2 , and R 3 are 66 mm, 59 mm, and 52 mm, respectively, the height h of the vertical surface 3' is 3 mm, and the outer diameter is 58 mm.
The rate of occurrence of eccentricity and the rate of occurrence of airtightness in the battery of the present invention in which an α-alumina ring 2 with a height of 9 mm and a height of 9 mm is arranged and thermo-pressure bonded on the bottom surface, and a conventional battery without a step as shown in Fig. 1. The results are shown in Table 1.

価値を高めるものである。[Table] As is clear from Table 1, 70% of conventional batteries had eccentricity, 20% had poor airtightness, and in the most severe cases, the anode cover 3 was deformed. On the other hand, in the battery of the present invention, neither eccentricity nor poor airtightness occurred. Effects of the Invention As mentioned above, the present invention allows the α-alumina ring to be held by the vertical surface of the step provided on the anode cover that is thermo-pressure bonded to the lower surface of the α-alumina ring, thereby preventing eccentricity with respect to the solid electrolyte tube. This prevents airtightness from occurring and increases the practical value of sodium-sulfur batteries.
