Sodium-sulfur battery and its manufacture

Abstract

Abstract PURPOSE:To prevent the adhesion of sodium to the top of a cathode terminal by connecting the bottom with the metallic fiber inside a solid electrolyte tube, and arranging a cathode collecting vessel, which has a hole and an upward projection at the bottom, and then filling sodium in the cathode chamber. CONSTITUTION:A metallic fiber 2 is so wound as to provide a center hole, and it is stored in 4 solid electrolyte tube 1 so as to constitute a cathode chamber 3. On the other hand, a cathode collector vessel 13, which has an inward projection 15A at one part of the side and a hole 14 and an upward projection 15B at the bottom, is prepared. And an O ring 16 is arranged at the step 13' of the cathode collecting vessel 13, and a sodium tank 17 filled with sodium 8 is positioned above it, and during heating the air is exhausted from inside the cathode chamber through the hole 14, and then a hole is opened in the sodium tank 17 by the projection 15B thereby filling sodium 8 in the cathode chamber by vacuum. Hereby, sodium never adheres to the top of the cathode terminal 5'.
