Abstract
Official abstract text for this publication.
A metal-air battery includes: an air electrode; a negative electrode; an ion exchange membrane that separates the air electrode and the negative electrode from each other; an air-electrode-side electrolytic solution that is disposed between the air electrode and the ion exchange membrane; and a negative-electrode-side electrolytic solution that is disposed between the negative electrode and the ion exchange membrane. The negative-electrode-side electrolytic solution contains a surfactant.
First claim

1 . A metal-air battery comprising: an air electrode; a negative electrode; an ion exchange membrane that separates the air electrode and the negative electrode from each other; an air-electrode-side electrolytic solution that is disposed between the air electrode and the ion exchange membrane; and a negative-electrode-side electrolytic solution that is disposed between the negative electrode and the ion exchange membrane, wherein the negative-electrode-side electrolytic solution contains a surfactant. 2 . The metal-air battery according to claim 1 , wherein the ion exchange membrane contains at least two kinds of atoms selected from the group consisting of carbon atoms, hydrogen atoms, oxygen atoms, nitrogen atoms, sulfur atoms, sodium atoms, potassium atoms, and phosphorus atoms. 3 . The metal-air battery according to claim 1 , wherein the negative electrode contains at least one element selected from the group consisting of magnesium, zinc, aluminum, iron, and calcium. 4 . The metal-air battery according to claim 1 , wherein the air electrode includes a co-continuous body that has a three-dimensional network structure in which a plurality of nanostructures is integrated by non-covalent bonding. 5 . The metal-air battery according to claim 2 , wherein the negative electrode contains at least one element selected from the group consisting of magnesium, zinc, aluminum, iron, and calcium. 6 . The metal-air battery according to claim 2 , wherein the air electrode includes a co-continuous body that has a three-dimensional network structure in which a plurality of nanostructures is integrated by non-covalent bonding. 7 . The metal-air battery according to claim 3 , wherein the air electrode includes a co-continuous body that has a three-dimensional network structure in which a plurality of nanostructures is integrated by non-covalent bonding.
