Abstract
Provided is a metal-air battery which is improved in battery performance such as stability in charge/discharge cycle characteristics by suppressing the generation of byproducts not only on the metal anode but also on the air cathode. A metal-air battery of the present invention includes an anode 1, an air cathode 3 and an electrolyte 2 that is interposed between the anode 1 and the air cathode 3, wherein the anode 1 contains aluminum, the electrolyte 2 contains an ionic liquid or a non-aqueous electrolyte solution, and the air cathode 3 contains a non-oxide ceramic.
