Abstract

The present invention relates to a rechargeable electrochemical battery cell having a housing, a positive electrode, a negative electrode, and an electrolyte, the electrolyte containing sulfur dioxide and a conductive salt of the active metal of the cell. The total quantity of oxygen-containing compounds contained in the cell that are able to react with the sulfur dioxide, reducing the sulfur dioxide, is not more than 10 mMol per Ah theoretical capacitance of the cell.
