Abstract
Official abstract text for this publication.
A metal air battery includes an air electrode containing a conductive material and a catalyst, a negative electrode containing a metal, and an electrolyte having ionic conductivity. The conductive material contains a co-continuous body of a three-dimensional network structure in which nanostructure bodies are branched, and the catalyst contains oxide having a cage-shaped crystal structure.
First claim
Opening claim text (preview).
1 . A metal air battery, comprising: an air electrode containing a conductive material and a catalyst; a negative electrode containing a metal; and an electrolyte having ionic conductivity, wherein the conductive material contains a co-continuous body of a three-dimensional network structure where nanostructure bodies are branched, and the catalyst contains oxide having a cage-shaped crystal structure. 2 . The metal air battery according to claim 1 , wherein calcium dodeca-oxide aluminum hepta-oxide (12CaO·7Al 2 O 3 ) is used as the oxide. 3 . The metal air battery according to claim 1 , wherein the oxide includes a monoatomic metal. 4 . The metal air battery according to claim 3 , wherein the monoatomic metal contains at least one type of element selected from the group consisting of iron, manganese, zinc, copper, and molybdenum. 5 . A manufacturing method for an air electrode, the method comprising: performing heat treatment on oxide having a cage-shaped crystal structure under an oxygen atmosphere to increase a concentration of oxygen ion radicals included in the oxide; performing heat treatment on the oxide with the increased concentration of the oxygen ion radicals under at least one type of atmosphere selected from the group consisting of atmospheres of an alkali metal, an alkaline earth metal, and titanium vapor to increase electrical conductivity of the oxide; and carrying the oxide with the increased electrical conductivity on a conductive material, wherein the conductive material contains a co-continuous body of a three-dimensional network structure where nanostructure bodies are branched. 6 . The manufacturing method for the air electrode according to claim 5 , further comprising: fixing a monoatomic metal to the oxide. 7 . The metal air battery according to claim 2 , wherein the oxide includes a monoatomic metal.
