| 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. <IMAGE> |
