Abstract

A positive electrode for an air battery that can remarkably improve the battery performance is provided by uniformly dispersing fine Nb (Nb oxide) therein. An air battery using the positive electrode as well as a method of manufacturing the positive electrode is also provided. A positive electrode for an air battery includes an expanded graphite sheet containing expanded graphite and Nb dispersed within the sheet. It is desirable that the Nb be contained in a weight proportion of from 5 ppm to 50000 ppm with respect to the expanded graphite.
