Title:

POSITIVE-ELECTRODE CATALYST FOR METAL-AIR BATTERY, AND METAL-AIR BATTERY

Document Type and Number:

WIPO Patent Application WO/2019/065284

Kind Code:

A1

Abstract:

Provided is a positive-electrode catalyst which has excellent durability and excellent activity in the environment in which a metal-air battery is operated. The positive-electrode catalyst for a metal-air battery according to the present invention includes a melilite composite oxide represented by general formula (BazSr1-z)2CoxFe2-2x(SiyGe1-y)1+xO7 (in the formula, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, and 0 ≤ z ≤ 1).
