ABSTRACT:
An alkali metal-sulphur cell comprising an outer tube, an inner tube forming the solid electrolyte of the cell and dividing the interior of the outer tube into anode and cathode compartments adjacent respective sides of the inner tube, and an alkali metal reservoir communicating with the anode compartment, has a gas space above the alkali metal in the reservoir, such that at the operating temperature of the cell the gas pressure in the reservoir will force alkali metal to flow from the reservoir into the anode compartment to maintain the operative surface area of the inner tube covered with liquid alkali metal during discharge of the cell. An advantageous method of forming such a cell entails evacuating the anode compartment when empty of alkali metal. A further advantageous method feature is to form the reservoir with the contained alkali metal and gas space as a sub-assembly.
