(JA) 金属空気電池
Abstract
(EN)
This metal-air battery is characterized by comprising an electrolyte solution tank, a metal electrode that is provided in the electrolyte solution tank and serves as an anode, an air electrode that serves as a cathode, an injection channel for supplying an electrolyte solution into the electrolyte solution tank, and a discharge channel for discharging the electrolyte solution from the electrolyte solution tank. This metal-air battery is also characterized in that the electrolyte solution tank has an inclined surface at the bottom and the opening of the discharge channel in the electrolyte solution tank is provided in the vicinity of the lower edge of the inclined surface.
