で、電圧の低下で破損電池の確認を行った。Now, we fabricated 10 sep each of the battery of the present invention as shown in Fig. 1 and the conventional battery as shown in Fig. 3.
A heat cycle test was conducted at a temperature increase/decrease rate of 150°C to 200°/h, and the results are shown in Table 1. In Table 1, the numerator indicates the number of batteries from which active material leaked, and the denominator indicates the number of damaged batteries.

Further, even if the battery is damaged, the lower part of the cathode current collector container 13 from the stepped portion is fused due to the heat of the direct reaction between sodium and sulfur, thereby preventing the occurrence of an internal short circuit. Furthermore, this manufacturing method can reduce the time and parts required for filling sodium, making it suitable for mass production.
