ABSTRACT:
A high temperature rechargeable electrochemical cell is provided, comprising a housing divided by a pair of concentric separator tubes into two anode compartments each containing molten alkali metal active anode material, the alkali metal in each anode compartment being electronically connected to the alkali metal in the other anode compartment, and a cathode compartment sandwiched between the anode compartments. The cathode compartment contains cathode material comprising a porous electrolyte-permeable electronically conductive matrix with a charged state in which it has a transition metal halide active cathode material dispersed therein, the matrix being impregnated with molten salt electrolyte. The cell comprises a cathode current collector tube located between the separator tubes, so that an inner part of the cathode is located between the smaller separator tube and the current collector tube, an outer part of the cathode being located between the current collector tube and the larger separator tube.
