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.

摘要： An electrochemical storage cell (20) includes ceramic housing frame (22) with a flat plate solid ceramic electrolyte (32) bonded to a internal shoulder (26) of the housing frame (22) with a glassy seal (33). A metallic weld ring (34) is bonded to each end of the housing frame (22). Each weld ring (34) has a welding flange (36) disposed parallel to a respective end of the housing frame (22) and also has a bonding flange (40). The bonding flange (40) lies parallel and adjacent to an internal surface (24) of the housing frame (22) if the coefficient of thermal expansion of the weld ring (34) is less than that of the housing frame (22), and parallel and adjacent to an external surface (28) of the housing frame (22) if the coefficient of thermal expansion of the weld ring (34) is greater than that of the housing frame (22). A glassy seal (42) is formed between the bonding flange (40) of each weld ring (34) and the respective adjacent surface (24 or 28) of the housing frame (22). The glassy seals (33 and 42) are formed by heating an assembly of the components to the glass transition temperature of the glassy seal material to effect bonding and then slowly cooling to minimize thermal stresses.

摘要： A sodium-sulfur electrical storage cell (10) has a planar solid electrolyte (16) that is permeable to sodium ions, a planar permeable porous cathode (24) filled with sulfur, a planar permeable porous anode (28) filled with sodium, and an electrically nonconducting, closed flat container (12) for these elements. The electrolyte (16) is thin and strengthened, as by an integral supporting structure (22), or supported, as by a structural anode core structure (36) or by cross members (22) of the container, to minimize its deformation during operation. The anode (28) and cathode (24) are electrically conducting even without sodium and sulfur present, so that the cell (10) fails to a shorted state.
