Abstract: In a metal-air battery, a negative electrode, an electrolyte layer, and a positive electrode are concentrically disposed in the stated order, radially outward from the central axis, and the outer circumferential surface of the positive electrode is enclosed by a liquid-repellent layer (29). The liquid-repellent layer (29) includes a relatively high-strength inorganic porous material (292) having a continuous pore structure, and a fluorine-based porous part (293) formed by fusing fluorine-based particles to each other. The fluorine-based porous part (293) is fused to the inorganic porous material (292) in pores (294) of and on the outer surface (295) of the inorganic porous material (292). This makes it possible to provide the liquid-repellent layer (29) that is a functional porous material having desired mechanical strength, gas permeability, and liquid impermeability.

Abstract: 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).

Abstract: A metal-air battery (1) includes a porous negative electrode (3) having a tubular shape and containing a metal, a porous positive electrode (2) having a tubular shape that surrounds the outer surface of the negative electrode (3), and an electrolyte layer (4) disposed between the negative electrode (3) and the positive electrode (2) and containing electrolyte solution. A filled part (31) enclosed by the inner surface of the negative electrode (3) is filled with electrolyte solution, and the electrolyte layer (4) is in communication with the filled part (31) via the porous negative electrode (3). The metal-air battery (1) further includes a supply-collection part (6) for collecting electrolyte solution in the filled part (31) and supplying electrolyte solution to the filled part (31). This facilitates replacement or the like of the electrolyte solution contained in the electrolyte layer (4).
