| 摘要 |
The present invention primarily intends to provide an air secondary battery that can inhibit deterioration in charge-discharge properties caused by oxygen generated in an air cathode layer during charge. To attain the object, the invention provides an air secondary battery comprising: a power generating element constituted of an air cathode layer containing a conductive material, an anode layer containing an anode active material, and an electrolyte layer formed between the air cathode layer and the anode layer; and an exterior body that houses the power generating element, wherein the exterior body is hermetically sealed with an oxygen-containing gas encapsulated therein; and at a charge start time, a pressure inside of the exterior body is lower than an atmospheric pressure.
