Cooper, T O; Miller, W E

A secondary electrochemical cell includes electrodes separated by a layer of electrically insulative powder. The powder includes refractory materials selected from the oxides and nitrides of metals and metaloids. The powdered refractory material, blended with electrolyte particles, is compacted as layers onto an electrode to form an integral electrode structure and assembled into the cell. The assembled cell is heated to its operating temperature; porous layers of electrically insulative, refractory particles containing molten electrolyte are left between the electrodes. 2 figures, 1 table.
