摘要:
A sodium-chalcogen cell is described which is operable at room temperature, in particular a sodium-sulfur or sodium-oxygen cell, the anode and cathode of which are separated by a solid electrolyte which is conductive for sodium ions and nonconductive for electrons. The cathode of the sodium-chalcogen cell includes a solid electrolyte which is conductive for sodium ions and electrons. Moreover, a manufacturing method for this type of sodium-chalcogen cell is described.
