Title:
METAL-AIR BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/080115
Kind Code:
A1
Abstract:
This metal-air battery (1) is provided with: a cylindrical positive electrode (2); a negative electrode (3) that faces the inner surface of the positive electrode (2); and an electrolyte layer (4) that is arranged between the negative electrode (3) and the positive electrode (2). The positive electrode (2) is provided with a porous positive electrode main body (21) which is a cylindrical supporting body formed of a conductive ceramic, and a separator (41), which is a porous film formed of an insulating ceramic, is arranged on the inner surface of the positive electrode main body (21). By using the positive electrode main body (21) as a supporting body in this manner, the positive electrode (2) is able to be easily increased in the thickness, and the battery performance of the metal-air battery (1) is able to be improved by decreasing the electrical resistance of the positive electrode (2).
