AIR CELL POSITIVE ELECTRODE, AIR CELL EMPLOYING THIS POSITIVE ELECTRODE, AND METHOD FOR MANUFACTURING SAID POSITIVE ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2016/088891

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide an air cell positive electrode into which fine Nb (Nb oxide) is uniformly dispersed, whereby the cell characteristics can be dramatically improved; an air cell employing this positive electrode; and a method for manufacturing said positive electrode. This air cell positive electrode is characterized by comprising an expanded graphite sheet having expanded graphite and Nb that has been dispersed through the sheet interior using an Nb-containing sol solution. The weight proportion of the Nb with respect to the expanded graphite is preferably 5-50,000 ppm.
