US 10,312,562 B2 · Metal-oxygen battery system having a suction function and a blowing function

Abstract

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.

Dependent claims

A metal-oxygen battery system, comprising:

at least one battery cell, including an oxygen cathode, a metal anode, and a metal ion-conducting separator situated between the cathode and the anode;
and
a turbomachine system connected to the oxygen cathode in a gas-conducting manner and which is switchable over between a suction function and a blowing function, and an exhaust gas supply line to supply a gas low in oxygen to the oxygen cathode;
wherein the turbomachine system is equipped with a suction function and a blowing function, so that supplying gas, which includes oxygen, to the oxygen cathode, and discharging gas, which includes oxygen, from the oxygen cathode is facilitated by the turbomachine system.
