Mathers, J P; Olszanski, T W; Boquist, C W

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 metalloids. The powdered refractory material, blended with electrolyte particles, can be compacted in layers with electrode materials to form an integral electrode structure or separately assembled into the cell. The assembled cell is heated to operating temperature to leave porous layers of electrically insulative, refractory particles containing molten electrolyte between the electrodes. 3 figures.
