A rechargeable electrochemical battery cell comprises a molten carbonate salt electrolyte (32) whose anion transports oxygen between a metal electrode (34) and an air electrode (30) on opposite sides of the electrolyte (32), where the said molten salt electrolyte (32) is retained inside voids of a porous electrolyte supporting structure sandwiched by the said electrodes, and the molten salt comprises carbonate including at least one of the alkaline carbonate including Li2CO3, Na2CO3, and K2CO3, having a melting point between 400° C. and 800° C. |
