Sodium-sulfur storage battery
A sodium-sulfur storage battery is described comprising: an alpha alumina ring having a longitudinally extending recess therein, a sodium conductive solid electrolyte tube having a longitudinal end disposed in the recess, the end being of smaller cross-section than the recess to define an annular space therebetween, and solder glass disposed in the annular space to join the ring to the tube. The annular space includes a longitudinally inner portion and an enlarged longitudinally outer portion, each portion containing the solder glass, the enlarged outer portion situated at an open longitudinal end of the recess and defining a groove for collecting the solder glass, the glass being positioned in the groove by substantially filling the groove with molten glass, and allowing the molten glass to harden such that no portion of an outer surface of the glass projects beyond an outer edge of the groove. At least a portion of the glass outer surface extends inside of the groove outer edge, the groove having a width in a radial direction in the range of from 0.2 mm to 5.0 mm and a depth in the longitudinal direction in the range of from 0.2 to 10.0 mm.
