ABSTRACT:
The invention provides a high temperature rechargeable electrochemical power storage cell having an alkali metal anode molten at the cell operating temperatrure. A solid electrolyte separator conductive of ions of the anode separates the anode from a cathode having an electronically conductive electrolyte-permeable porous matrix impregnated with liquid electrolyte comprising cations of the anode metal and halide ions. Dispersed in the porous interior of the matrix is an electronically active cathode substance substantially insoluble in the liquid electrolyte. The separator is a sheet and the matrix of the cathode has the same peripheral outline as the sheet. The matrix is opposed to the sheet and is in register face-to-face therewith. The separator and sheet are located in a cell housing divided by the separator into an anode compartment containing the anode and a cathode compartment containing the cathode.
