METAL-AIR BATTERY

摘要

In a metal-air battery (1), an interconnector (24) formed of ceramic having alkali resistance is provided on the surface of a porous positive electrode layer (2) on the side opposite to the surface that is in contact with an electrolyte layer (4). A liquid repellent layer (29) having liquid repellency to an electrolyte solution is further provided on the surface of the positive electrode layer (2) on which the interconnector (24) is formed, and covers this surface along with the interconnector (24). The metal-air battery (1) using an alkaline electrolyte solution can thus easily prevent leakage of the electrolyte solution by the interconnector (24) and the liquid repellent layer (29) while suppressing degradation of the interconnector (24).

1. A metal-air battery comprising:
a negative electrode layer; a porous positive electrode layer that opposes said negative electrode layer; an electrolyte layer disposed between said negative electrode layer and said positive electrode layer and containing an alkaline electrolyte solution; an interconnector formed of ceramic having alkali resistance and provided on a surface of said positive electrode layer on a side opposite to a surface of said positive electrode layer that is in contact with said electrolyte layer; and a liquid repellent layer having liquid repellency to said electrolyte solution and covering, along with said interconnector, the surface of said positive electrode layer on which said interconnector is provided.
