Abstract
Official abstract text for this publication.
A non-aqueous type magnesium oxygen battery including a negative electrode, a positive electrode, a non-aqueous magnesium ion conductor, and a promoter is described. The negative electrode is configured to absorb magnesium and release magnesium ion. The positive electrode is configured to produce a discharge product that includes magnesium and oxygen during a discharge process of the battery. The non-aqueous magnesium on conductor is between the negative electrode and the positive electrode. The promoter is included with the positive electrode. The promoter is configured to promote MgO 2 (magnesium peroxide) production during the discharge process of the battery.
First claim

What is claimed is: 1. A non-aqueous type magnesium oxygen battery comprising: a negative electrode configured to absorb magnesium and release magnesium ion; a positive electrode configured to produce a discharge product that includes magnesium and oxygen during a discharge process of the battery; a non-aqueous magnesium ion conductor between the negative electrode and the positive electrode; a promoter included with the positive electrode, the promoter is configured to promote MgO 2 (magnesium peroxide) production during the discharge process of the battery; and wherein the promoter is MgO 2 . 2. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the promoter is configured to adsorb magnesium ion. 3. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the promoter is configured to adsorb or reduce molecular oxygen without a dissociation reaction to atomic oxygen. 4. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the promoter includes MgO 2 , conductive member and bonding member. 5. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the promoter promotes formation of MgO 2 with (111) facets. 6. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the promoter promotes formation of MgO 2 with (001) facets that are stoichiometric or oxygen-rich. 7. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the battery is configured to provide a discharge voltage of greater than 1.1 volts. 8. The non-aqueous type magnesium oxygen battery of claim 1 , wherein the battery is configured to provide a discharge voltage of at least 1.8 volts. 9. The non-aqueous type magnesium oxygen battery of claim 5 , wherein the battery is configured to provide a discharge voltage of at least 2.6 volts. 10. A non-aqueous type magnesium oxygen battery comprising: a negative electrode configured to absorb magnesium and release magnesium ion; a positive electrode configured to produce a discharge product that includes magnesium and oxygen; a promoter included with the positive electrode, the Promoter includes MoO 2 , and the promoter promotes formation of MgO 2 having a (111) facet; and a non-aqueous magnesium ion conductor between the negative electrode and the positive electrode; wherein the battery is configured to provide a discharge voltage of greater than 1.1 volts. 11. The non-aqueous type magnesium oxygen battery of claim 10 , wherein the battery is configured to provide a discharge voltage of at least 1.8 volts. 12.
