Abstract: A method of maintaining the performance level of an electrochemical cell is described. The cell usually includes a negative electrode that includes an alkali metal; a positive electrode that includes at least one transition metal halide; a molten salt electrolyte based on an alkali metal haloaluminate; and a sodium ion-conducting solid electrolyte partitioning the positive electrode from the negative electrode. The method is based on a treatment regimen that includes the step of applying a series of electrical cycles to the cell, wherein the series includes at least one deep discharge of the cell. Each discharge of the cell is usually followed by recharging the cell to its available capacity.

Abstract: An electrochemical cell is provided that includes a cathode chamber including a cathode material and an ion sequestering material, an anode chamber including a molten alkali metal material and a separator disposed in an ionic conductivity path between the cathode chamber and the anode chamber. The electrochemical cell demonstrates a reduced increase in discharge resistance.
