Claim Text:
1. A method of making a molten sodium battery comprising: a. providing a first metallic interconnect frame having a first interconnect vent hole, anode chamber and cathode chamber; b. providing a second metallic interconnect frame having a second interconnect vent hole, anode chamber and cathode chamber; c. interposing an electrolyte plate having a cathode vent hole and an anode vent hole between the metallic interconnect frames; and d. sealing the metallic interconnect frames and the electrolyte plate thereby forming gaseous communication between the anode chamber of the first interconnect frame through the anode vent holes and gaseous communication between the cathode chamber of the second interconnect frame through the cathode vent holes, wherein the vent holes minimize a pressure differential within the battery during a charge/discharge cycle.
