ABSTRACT:
The invention relates to an electrochemical storage cell on the basis of alkali metal and chalcogen, particularly sodium and sulfur. The storage cell has an anode space for receiving the anolyte and a cathode space for receiving the catholyte. The two spaces are separated from each other by a cup-shaped solid electrolyte. The solid electrolyte is surrounded in the region of the anode space by a capillary structure over the entire length. The capillary structure has at least one widened portion which is formed by an outward-pointing bulge of the capillary structure. The widened portion extends over the entire length of the capillary structure. Each widened portion is traversed in its interior by a canal. The cylinder surface of this canal is formed by a metal screen. The entrance opening of this canal is directly adjacent to the exit opening of a supply container for the sodium.
