An anode for a galvanic cell is constructed from an anode material containing a main component, which releases lithium ions during a discharge process of the galvanic cell, and at least one additive. The at least one additive has an electrochemical potential which is higher with respect to elemental lithium than an electrochemical potential of the main component with respect to elemental lithium. The at least one additive has a charging capacity and a discharging capacity, and the charging capacity does not deviate from the discharging capacity by more than 10%.

Composite anode for a galvanic cell and a galvanic cell

A metal-oxygen battery system, in particular a lithium-oxygen battery system, includes at least one battery cell, in particular a lithium-oxygen cell, including an oxygen cathode, a metal anode, and a metal ion-conducting separator situated between the cathode and the anode. To increase the current carrying capacity, the battery system also includes a turbomachine system which is connected to the oxygen cathode in a gas-conducting manner and which may be switched over between a suction function and a blowing function, and/or an exhaust gas supply line for supplying a gas low in oxygen to the oxygen cathode. Also described is a corresponding operating method.
