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 an open port is provided for the insert container. 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 flows through the open port into the annular chamber.
