ABSTRACT:
A high temperature rechargeable electrochemical power storage cell comprises an anode compartment containing a molten alkali metal anode; a cathode compartment containing an alkali metal aluminum halide molten salt electrolyte, and a cathode which comprises an electronically conductive electrolyte-permeable porous matrix which has dispersed therein an active cathode substance, with the matrix being impregnated with said molten electrolyte; a separator separating the anode compartment from the electrolyte; and at least one bimetallic current collector in one of the cell compartments. The bimetallic current collector is such that, when the cell is at ambient temperature, the current collector is in a first non-deformed configuration. However, when the cell is at its normal operating temperature, the current collector is in a second deformed configuration. The deformation of the current collector results from the difference in co-efficients of thermal expansion of the metals making up the bimetallic current collector. The current collector in its second configuration bears against the separator, thereby to make electrical contact with the separator.
