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 aluminium halide molten salt electrolyte as well as a cathode which comprises an electronically conductible 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 a wick in the anode compartment to enhance contact of alkali metal with the separator in the anode compartment. The wick comprises a layer of alkali metal wettable particles on the separator surface, and a metallic anchoring component abutting the wettable particles and protruding into the anode compartment.
