摘要： 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.

摘要： An expanded graphite sheet and a battery using the expanded graphite sheet are provided, that can inhibit the expanded graphite sheet from swelling even when the expanded graphite sheet is used for, for example, a positive electrode for an air battery.
An expanded graphite sheet includes an expanded graphite and has a surface water contact angle of greater than or equal to 90 degrees and a surface resistivity of less than or equal to 70 mΩ/sq. It is desirable that a polyolefin resin be contained in the expanded graphite sheet in a dispersed state. It is desirable that the polyolefin resin be polypropylene.

摘要： Apositive electrode for an air battery and an air battery using the positive electrode are provided, that make it possible to inhibit an electrolyte solution decrease in the battery and prevent the problems associated with the electrolyte solution decrease without causing an increase in manufacturing costs.
A positive electrode for an air battery includes an expanded graphite sheet. It is desirable that the expanded graphite sheet contain expanded graphite in an amount of 80 mass % or greater. It is desirable that the expanded graphite have a bulk density of from 0.2 Mg/m 3 to 2.0 Mg/m 3 . It is desirable that the expanded graphite sheet have a thickness of from 0.1 mm to 3.0 mm.
