Abstract

A positive active material for a positive electrode of a battery cell which includes a first component containing a compound of general formula: Li2-zNazM11-yM2yO3, where M1 and M2 are different from one another and stand for transition metal ions, 0<y<1, and 0≤z<2, with the condition that the compound is essentially free of manganese ions. Moreover, a positive electrode of a battery cell which includes the positive material, and a battery cell which includes at least one positive electrode, are also described.
