A battery cell comprising a negative electrode, a positive electrode, and a non-aqueous electrolyte mixture is described. The positive electrode includes a lithium metal oxide, and the negative electrode is selected from the group consisting of an intercalated metal, a metal oxide, a metal carbide, a composite formed of the intercalated metal or metal oxide and carbon. The electrolyte mixture comprises at least one compound (1), a lithium salt (1) and a lithium salt (2). The battery cell is used to suppress harmful side reactions that can cause gas formation. Meanwhile, the internal resistance is not increased. In addition, the conductivity of the electrolyte is improved. Furthermore, a corresponding electrolyte mixture is described. 描述了一种包括负电极、正电极和非水性电解质混合物的电池单池。所述正电极包括锂金属氧化物，所述负电极选自嵌入的金属、金属氧化物、金属碳化物、由嵌入的金属或金属氧化物与碳形成的复合物。所述电解质混合物包含至少一种化合物(1)、锂盐(1)和锂盐(2)。利用所述电池单池来抑制可导致气体形成的有害的副反应。同时，内阻不增加。另外，提高了电解质的传导性。此外，描述了相应的电解质混合物。
