Abstract: A method is disclosed for bonding nitride and oxide film electrodes on ceramic substrates, which can be used in thermo electric generators. Hydride powders in suspension are coated on a substrate, and heated to selected temperatures for selected periods of times in alternating atmospheres of hydrogen and nitrogen, or oxygen. The method produces satisfactory film electrodes, including electrodes which are greater than 10 microns in thickness.

Abstract: 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.
