Abstract
A metal-air battery cell capable of generating constant output power. The metal-air battery cell may include a metal anode including an end and a lateral surface extending from the end, a cathode surrounding and spaced apart from the lateral surface of the metal anode, an electrolyte between the metal anode and the cathode and in contact with the end of the metal anode and a portion of the lateral surface of the metal anode, and an anode injector configured to move the metal anode to increase an area of the lateral surface of the metal anode contacting the electrolyte.
