Abstract
Secondary lithium-ion cells which include at least one lithium-intercalating, carbon-containing negative electrode, a nonaqueous lithium ion-conducting electrolyte and at least one lithium-intercalating positive electrode including a lithium-containing chalcogen compound of a transition metal, the electrodes being separated from one another by separators. A lithium-containing auxiliary electrode is disposed in the cell to compensate for the irreversible capacity loss in the secondary lithium-ion cell.
