Abstract

PURPOSE:To be able to ensure electrical insulation between a battery and housing case even if molten sulfur leaks from the battery by battery failure by supporting supporting cylinders of a sodium-sulfur battery with supporting insulators in a specified height and by installing recesses on the surface of each supporting insulator. CONSTITUTION:Supporting insulators 1 are set up on the bottom plate of a housing case 15 and supporting cylinders 2 are set up thereon. A recess 1f is formed in a specified height between a supporting stand 1a and a head 1b of each supporting insulator 1. A glass tape 4 is sticked on the inner wall of a supporting cylinder main body 3 and a sodium-sulfur battery is accommodated therein. Even if molten sulfur of cathode active material leaks into the supporting cylinder from the battery by battery failure, the molten sulfur drops from a rib 1e along the head 1b of the supporting insulator 1 from the lower part of the supporting cylinder 2. This prevents electrical connection of the battery with the housing case 15 through the supporting cylinder. Electrical insulation between the battery and housing case is ensured even if molten sulfur leaks by battery failure.
