Abstract
An air battery includes a negative electrode allowing a metal ion to be occluded in the negative electrode and released from the negative electrode, a positive electrode configured to use oxygen in the air as a positive electrode active material, a nonaqueous metal ion conductor disposed between the negative electrode and the positive electrode, and oxygen evolving catalysts. The positive electrode includes a carbon material. At least one of the oxygen evolving catalysts is fixed to the surface of the carbon material through a Si—O bond.
