Pressing-type cylindrical metal air battery

Abstract

The present invention relates to a metal air battery for improving storage performance. The present invention provides a pressing-type cylindrical metal air battery which comprises: an external case which is formed in a cylindrical shape, and has a cathode terminal on one side and an anode terminal hole on the other side; an internal case which is formed in a cylindrical shape and coaxially inserted into the inside of the external case, has an anode terminal that is inserted into or extracted from the inside or the outside of the anode terminal hole on one side, and has an air inflow hole on the surface of a wall so that air can flow into the air inflow hole; and an elastic sealing means which is formed on the one side of the internal case, enables the air to flow into the anode terminal hole by elastically pressurizing the anode terminal when a battery is inserted into a battery compartment, and seals the anode terminal hole by elastically restoring the anode terminal again if the battery is separated from the battery compartment. Because the invention has a double structure comprised of the external case and the internal case, the air inflow hole of the internal case can be opened to or sealed from the outside when the battery is inserted into or separated from the battery compartment, thereby easily blocking the inflow of the air if the battery is not in use. Consequently, the present invention has the advantage of improving the storage performance by reducing natural discharge of the battery.
