Abstract
The invention provides a high temperature rechargeable electrochemical power storage cell comprising a cell housing defining a cathode compartment containing a cathode and containing an anode structure located within the cathode compartment and comprising a plurality of holders filled with active anode material which is molten at the operating temperature of the cell. The anode structure defines a conduit containing active anode material and the holders are flattened in shape and spaced along the conduit in series from one another. The interior of each holder is in communication with the conduit and each holder has a pair of oppositely outwardly facing major faces extending transversely to the conduit and comprising a material which is a conductor of the active anode material. The cathode occupies the spaces between the holders and the cell includes a reservoir for active anode material in communication with the conduit, the reservoir in all states of charge of the cell being at least partially filled with active anode material.
