  • Catalyst for air electrode, air electrode including catalyst for air electrode, and air secondary battery including air electrode
    Patent number: 11811069
    Abstract: A battery includes: an electrode group including an air electrode and a negative electrode that are stacked with a separator interposed therebetween; and a container housing the electrode group together with an alkaline electrolyte liquid. The air electrode includes a catalyst for an air electrode. This catalyst for an air electrode is a catalyst for an air electrode including an oxide containing at least bismuth (Bi), ruthenium (Ru), sodium (Na), and oxygen, and Na/(Ru+Bi+Na) representing an atomic ratio of the sodium to a sum of the bismuth, the ruthenium, and the sodium is 0.126 or more and 0.145 or less.

  • CATALYST FOR AIR SECONDARY BATTERY, AIR ELECTRODE, AND AIR SECONDARY BATTERY
    Publication number: 20230049091
    Abstract: A battery includes: an electrode group including an air electrode and a negative electrode that are stacked with a separator interposed therebetween; and a container housing the electrode group together with an alkaline electrolyte liquid. The air electrode includes a catalyst for an air secondary battery, and this catalyst for an air secondary battery includes a pyrochlore bismuth-ruthenium composite oxide having a full width at half maximum of a diffraction peak corresponding to a (222) face obtained by a powder X-ray diffraction method using CuK? rays as X-rays, of 0.350 deg or larger and 0.713 deg or smaller.
