Abstract
PURPOSE:To secure the safety of a sodium-sulfur battery even when the solid electrolyte tube is broken by placing a double negative component, which consists of an inner case filled with Na and an outer case, inside a solid electrolyte tube so that a space is formed between the outer case and the solid electrolyte tube, and connecting the spaces of the inner and the outer cases. CONSTITUTION:Since the space between a solid electrolyte tube 1 and an outer case 13 is under reduced pressure, molten Na contained in an inner case 12 is passed through a negative terminal tube 4', is introduced from the upper hole of the tube 4' into the former space for moistening the surface of the tube 1. After that, molten Na moistening the surface of the tube 1 permeates through the tube 1 into a positive active material 8, and reacts with the material 8 to discharge electricity. When any crack or the like develops in the tube 1, the material 8 directly reacts with a negative active material 2 to generate reaction heat, which causes the outer case 13 to be broken earlier than a battery case 10. As a result, the pressure inside the case 13 and that inside the space between the tube 1 and the case 13 are equalized, and molten Na comes not to be sucked through the tube 4'. Consequently, the safety of a sodium-sulfur battery is secured by limiting the amount of the direct reaction.
