Abstract
A metal-air cell having an anode/electrolyte and a cathode includes a container having an upper interior surface and a lower interior surface for housing the anode/electrolyte and the cathode; a spring disposed on the upper interior surface; a cover electrically connected to the cathode, and having at least one recess; and at least one o-ring disposed on the lower interior surface facing the at least one recess. The spring is compressed when a force is applied so that the at least one o-ring and the at least one recess are separated, thereby forming an inlet to introduce air for electrochemical reaction. The spring is expanded when the force is removed so that the at least one o-ring is inserted within the at least one recess to obstruct the air.
