Document Type and Number:

Japanese Patent JP7081762

Kind Code:

B2

Abstract:

A battery 2 includes an electrode group 6 including an air electrode 14 and a negative electrode 12 stacked with a separator 16 therebetween, and an accommodating bag 18 accommodating the electrode group 6 along with an alkali electrolyte solution. The air electrode 14 includes a catalyst for an air secondary battery. This catalyst for an air secondary battery is produced by a method for producing a catalyst for an air secondary battery, the method including a precursor preparation step of preparing a bismuth-ruthenium oxide precursor, a calcination step of calcining the bismuth-ruthenium oxide precursor obtained in this precursor preparation step to form a bismuth-ruthenium oxide, and a nitric acid treatment step of immersing the bismuth-ruthenium oxide obtained by this calcination step in a nitric acid aqueous solution.
