Abstract
An air battery includes a negative electrode, an air electrode, and an electrolyte that is interposed between the negative electrode and the air electrode. The air electrode includes: an oxygen evolution reaction layer for charging that is provided on an electrolyte side of the air electrode and contains an oxygen evolution reaction catalyst containing no carbon; an oxygen reduction reaction layer for discharging that is provided on an opposite side of the air electrode from the electrolyte and contains an oxygen reduction reaction catalyst containing carbon; and a current collector that is provided between the oxygen evolution reaction layer and the oxygen reduction reaction layer or in the oxygen evolution reaction layer.
