。(Problems to be Solved by the Invention) Sodium-sulfur batteries are a type of battery that operates at high temperatures and undergo large thermal changes due to starting and stopping, and sodium ions move within the solid electrolyte when charging and discharging the battery. In particular, solid electrolyte tubes are susceptible to cracks due to thermal stress and strain caused by passage of sodium ions.

に陥る可能性があり、安全性の面で問題を有している。In the conventional example shown in Fig. 3, a crank occurs in the solid electrolyte tube (1), and even if excessive sodium and sulfur react in that part and it becomes abnormally heated, it still functions as a current collector! As long as sodium is in contact with the cylindrical part (7) of (5), the operation of the battery will not be stopped, so a large current will continue to flow.
Furthermore, there is a risk of the crank expanding and causing abnormal overheating, which poses a safety problem.

13A) is made of aluminum with a wall thickness of 50 to 5 (11) μ or stainless steel with a wall thickness of 50 to 3 (11) μ, while the inner wall of the safety tube (13B) is made of aluminum that is larger than the outer wall of the safety tube (13^). Uses thick aluminum or stainless steel. In addition, the part indicated by the symbol (13C) in the figure below the safety tube 09 is made by compressing aluminum fibers, stainless steel fibers, etc. to the bottom of the cartridge (9) and the solid electrolyte tube (1).
It is a member molded appropriately according to the shape of the cartridge (9), and its porosity makes it possible to improve the supply of sodium from the hole 0ω on the bottom of the cartridge (9), as well as to prevent the cartridge (9) from being damaged during battery manufacture, transportation, operation, etc. It also serves as a buffer to prevent the solid electrolyte tube (1) from being damaged by impact. However, this member (13C) does not necessarily need to be provided; for example, the bottom of the cartridge (9) may be shaped approximately the same as the bottom of the solid electrolyte tube (1), and one safety tube may be placed on the inner surface of the solid electrolyte tube (1). It may also have a shape having a safety pipe wall inner space 04) filled with an inert gas throughout.

熱を抑制でき危険が回避できる。(Function and Effect) In a device configured in this way, strain is applied to the solid electrolyte tube (1) due to the heat cycle during battery operation and the movement of sodium ions, causing a crank, which causes excess sodium and sulfur to form in that part. When the reaction progresses and abnormal overheating occurs, the safety outer tube (13A) melts and the inert gas filled in the safety tube wall inner space 041 is released. Then, the inert gas accumulates above the gap 01), and the inert gas accumulates above the gap 01.
) is pushed downward, and when the sodium liquid level falls below the lower end of the cylindrical part (7) that collects current from the negative electrode and the contact is broken, the battery stops operating and current no longer flows. Damage will not spread further, and abnormal overheating can be suppressed to avoid danger.
