摘要： The invention provides a rechargeable electrochemical cell comprising a cell housing 10 divided by a separator 20 into a pair of electrode compartments, one of which contains an anode substance and the other of which contains an active cathode substance and an electrolyte. The anode and electrolyte are liquid at the operating temperature of the cell and the electrode compartments are each divided into a gas chamber communicating with an electrode chamber. The gas chamber contains an inert gas under pressure and the electrode chamber contains a liquid, namely the anode material or the liquid electrolyte. A wall of each electrode chamber is provided by the separator and each electrode chamber has a closeable bleed outlet 74, 80. The cell has an operative attitude in which said bleed outlets can be used to bleed gas from the associated electrode chambers, and each electrode chamber is in communication with the associated gas chamber, such that the cell in its operative attitude has each electrode chamber completely full of liquid, and each gas chamber containing inert gas under pressure and liquid.

摘要： An electrochemical cell is provided with a molten sodium anode and a molten sodium aluminium halide salt electrolyte. The cathode comprises FeCl.sub.2, NiCl.sub.2, CoCl.sub.2 or CrCl.sub.2 as active cathode substance dispersed in an electronically conductive electrolyte-permeable matrix which is impregnated by the electrolyte. Between the anode and the electrolyte, and isolating them from each other, is a solid conductor of sodium ions or a micromolecular sieve which contains sodium sorbed therein. The proportions of sodium and aluminium ions in the electrolyte are selected so that the solubility of the active cathode substance in the electrolyte is at or near its minimum.
