摘要： A method of pulse charging a secondary electrochemical storage cell is provided. The secondary cell includes a negative electrode comprising an alkaline metal; a positive electrode comprising at least one transition metal halide; a molten salt electrolyte comprising alkaline metal haloaluminate; and a solid electrolyte partitioning the positive electrode from the negative electrode, such that a first surface of the solid electrolyte is in contact with the positive electrode, and a second surface of the solid electrolyte is in contact with the negative electrode. The method of charging includes polarizing the cell by applying a polarizing voltage greater than about 0.1 V above the cell's rest potential for a first predetermined period of time; depolarizing the cell for a second predetermined period of time; and repeating the polarizing and depolarizing steps until a charging end-point is reached.
