A battery cell is described that includes a negative electrode, a positive electrode, and a non-aqueous electrolyte mixture. The positive electrode comprises lithium metal oxide, and the negative electrode is selected from intercalated metals, metal oxides, metal carbides, composites of intercalated metals or metal oxides and carbon. The electrolyte mixture comprises at least one compound (1), a lithium salt (1) and a lithium salt (2). The battery cells are utilized to suppress unwanted side reactions that can lead to gas formation. At the same time, the internal resistance does not increase. In addition, the conductivity of the electrolyte is improved. Furthermore, corresponding electrolyte mixtures are described. |
