昭５９−１５７９７２号公報の記載参照。）。(Prior art) Conventionally, collective sodium-sulfur battery devices usually have a fourth
As shown in the figure, a large capacity sodium-sulfur battery device is provided by arranging a large number of single cells and connecting them in series or parallel. By the way, sodium-sulfur batteries are 3
It is a battery that operates by melting the active material at a high temperature of 00 to 350 degrees Celsius, and it is active as the battery is charged and discharged. ! This type of battery is prone to damage to the solid electrolyte or the joint between metal and ceramics (solid electrolyte) due to changes in the volume of the yJ material and temperature changes due to repeated starting and stopping of the battery. When this type of damage occurs, sodium and sulfur react directly, generating abnormal heat, and furthermore, the battery container is destroyed, causing leakage of active materials such as sodium, sulfur, and sulfide. Due to its corrosive nature, in the conventional device shown in FIG. 4, other sodium-sulfur cells and even the containers containing the cells are at risk of destruction. Furthermore, if these leaked active materials touch the frame that fixes the stack, a ground fault may occur. Therefore, various efforts have been made to minimize the direct reaction between thorium and sulfur when the solid electrolyte of a battery is damaged, thereby preventing the battery container from being destroyed (for example, Japanese Patent Laid-Open No. 59-157972 (See information in the bulletin.)

Since ground faults may occur depending on the substance, there is a problem in safely operating collective sodium-sulfur batteries.
