Abstract

An electrolyte for a rechargeable non-aqueous electrochemical battery cell having a negative electrode and a positive electrode is described. The electrolyte contains sulfur dioxide and comprises a conducting salt, and a battery cell therefore has almost no capacitance loss over the cycles. Furthermore, a corresponding battery cell and a method for producing the electrolyte are described.
