−硫黄電池用ベータアルミナ管の焼成方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for firing a beta-alumina tube for a sodium-sulfur battery, and more specifically, a method for firing a beta-alumina tube formed into a thin-walled bottomed cylindrical shape. The present invention relates to a method for firing beta alumina tubes for sodium-sulfur batteries.

３５０℃で作動させる高温二次電池である。[Prior Art] A sodium-sulfur battery has molten metal sodium as a cathode active material on one side and molten sulfur as an anode active material on the other, and both have selective permeability to sodium ions. Isolated with beta alumina solid electrolyte, 300 ~
This is a high-temperature secondary battery that operates at 350°C.

極管７が貫通支持されている。The configuration of such a sodium-sulfur battery is, for example,
As shown in the figure, there is a cylindrical anode container 2 that accommodates an anode conductive material l such as carbon felt impregnated with molten sulfur S, which is an anode active material, and an upper end portion of the anode container 2 made of, for example, Alpha Alx. A cathode container 4 is connected via an insulator ring 3 and stores molten metal Na, and a cathode container 4 is connected to the inner circumference of the insulator ring 3 and has a function of selectively transmitting sodium ions Na''. In addition, in the center of the upper lid 6 of the cathode container 4, there is a cathode tube extending downward through the cathode container 4 to near the bottom of the beta alumina tube 5. 7 is supported through.

、２Ｖ程度の電圧を発生する。充電時には放電とは逆に
ナトリウム及び硫黄の生成反応が起こる。In a sodium-sulfur battery having the above configuration, during discharge, molten metal sodium releases electrons and becomes sodium ions, which pass through the beta-alumina solid electrolyte and move to the anode side, where they interact with the sulfur of the anode and the external circuit. It reacts with the electrons passing through it to produce sodium polysulfide, which generates a voltage of about 2V. During charging, sodium and sulfur production reactions occur, contrary to discharging.

いる。Conventionally, as a method for firing beta alumina tubes, there has been known a method in which the beta alumina tube is fired at the lower side of the open end of the formed beta alumina tube (so-called pre-baking method; see FIG. 3). In this pre-baking method, the lower part of the beta alumina tube formed body buckles due to the weight of the formed body, and dimensional tolerances such as straightness and roundness become large, making it difficult to manufacture thin-walled tubes.
また、上記置き焼き法の欠点を解消して薄肉管を製造す

ずる恐れがあった。As shown in FIG. 4, a hole 8 is drilled in the bottomed cylindrical beta alumina tube formed body 10, and a hanging rod 9 is passed through the hole 8, and the beta alumina tube formed body 10 is suspended while firing.
A point load was applied to the part where the hole 8 of the beta-alumina tube molded body 10 and the hanging rod 9 were in contact, and there was a fear that the hanging rod would break from the upper part of the hole 8.

The present invention was completed as a result of various studies in order to develop the system.
