An electrochemical cell includes an outer casing defining at least a portion of an anode electrode chamber, an ionically conducting separator disposed within the outer casing, an inner surface of the separator defining a cathode electrode chamber, a cathode electrode disposed within the cathode chamber, a conductive current collecting body coupled with the cathode electrode, an alkali metal-containing electrolyte disposed in the cathode electrode chamber, and a sealing body coupled with the outer casing and sealing the anode electrode chamber from an external atmosphere disposed outside of the outer casing. The electrolyte supplies alkali metal through the separator to the anode electrode chamber in response to an electric charge applied to the conductive current collecting body. A first content of a gas component in the anode electrode chamber is in the anode electrode chamber in an amount that is less than an amount of a second content of the gas component in ambient air.
