The ’503 Application is entitled Alkaline Earth Metal Ion Battery and is directed to an alkaline earth metal ion energy storage cell (10) which contains three liquid constituents: two liquid electrodes and a liquid electrolyte. More particularly, the cell (10) houses a molten metal body (14) that serves as a negative electrode, an electronically conductive liquid alloy body (16) that serves as a positive electrode, and an intervening ionically conductive electrolyte (20).

!ADVERTISEMENT!
According to the ’503 Application, calcium or magnesium is used in the liquid electrodes (14, 16) because these elements generate relatively high voltage, are safe to handle and are relatively inexpensive.
An electronically conductive container (22) houses the liquid constituents, including an electronically conductive lid (26). An insulating inner sheath (24) prevents shorting between the negative and positive electrode (14, 16), and an insulative seal (29) confines molten constituents and vapors to the container (22).
