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, a felt fabric with capillary activity located in the cathode chamber, and an additive lowering the viscosity of the sulfur in the cathode chamber. Preferred additives are selenium, boron and iodine. Lowering the viscosity of the sulfur permits recharging the cell to a greater capacity.
