Abstract

An electrochemical storage cell or battery based on an alkali metal and sulfur having at least one anode chamber and at least one cathode chamber separated from each other by an ion-conducting solid electrolyte, and felt with course-pores and/or low electric conductivity and felt with fine-pores and/or higher electric conductivity located in the cathode chamber, with the felt of coarse-pores and/or low conductivity disposed near the solid electrolyte and the felt of fine-pores and/or higher conductivity disposed further away from the solid electrolyte. This permits rapid and more complete recharging of the cell for covering peak loads in electrical networks.
