A separator for use in an advanced rechargeable electrochemical battery cell includes a thin plate of beta'' alumina affixed to a molded monolithic frame shaped similar to a window frame. The strength and support provided by the frame permits use of extremely thin beta'' alumina plates. When used in a sodium sulfur or sodium metal chloride battery cell, the separator permits maximum cell power without a decrease in cell energy capacity. A battery prepared by stacking a plurality of such cells is light and compact, yet has sufficient power and capacity for use in an electric vehicle.
