Patent ID: 8871395

Claim:
An air battery system comprising: an air battery cell which contains an air cathode, an anode, and a separator; an oxygen gas supply means for supplying an oxygen gas by bubbling to a nonaqueous liquid electrolyte; and an inert gas supply means for supplying an inert gas by bubbling to the nonaqueous liquid electrolyte, wherein the air cathode further contains an air cathode layer containing a conductive material, and an air cathode current collector for collecting current of the air cathode layer; the anode further contains an anode layer containing an anode active material which stores and releases a metal ion, and an anode current collector for collecting current of the anode layer; and the separator is provided between the air cathode layer and the anode layer, wherein the air cathode layer and the anode layer are constantly filled with the nonaqueous liquid electrolyte at a time of a change in a volume of the electrode caused by a discharge or a discharge and charge, and wherein a metallic oxide is generated at the air cathode at the time of discharge.
