ABSTRACT:
Molten sodium is filled into a reservoir insert container including a closed ended tubular portion and the sodium is solidified and the container sealed. Then the container is placed into the sodium compartment of a sodium sulfur cell so that the tubular portion extends into the electrolytic separator tube of the cell and is spaced apart therefrom forming an annular chamber. To activate the cell, the sodium is melted and an opening is formed in the insert container permitting flow of molten sodium from the container into the thus-formed chamber.
