  • Electrochemical storage cell
    Patent number: 4683179
    Abstract: Electrochemical storage cell of the sodium and sulfur type with an anode space and a cathode space which are separated from each other by a solid electrolyte and are bounded, at least in some regions, by a metallic housing. The cathode space contains the sulfur electrode which is made of a sulfur-impregnated graphite or carbon fiber material and the cathode space is subdivided into at least two and preferably more sectors which are separated from each other at least in some regions.

  • Electrochemical storage cell
    Patent number: 4659638
    Abstract: Electrochemical storage cell of the sodium and sulfur type with an anode space and a cathode space which are separated from each other by a solid electrolyte and are bounded at least in places, by a metallic housing, with the cathode space for forming the sulfur electrode, filled with fiber material of graphite or carbon which is saturated with sulfur. A defined ratio of the value p of the thickness (d.sub.S) of the sulfur electrode to the wall thickness (d.sub.K) of the solid electrolyte is fixed.
