Galvanic element having a porous solid-elektrolyte sinter framework containing the cathode material
In a galvanic solid cell, for example of the Na/SbCl/sub 3/ systems, the cathode space is occupied by a self-supporting porous sinter framework of solid electrolyte material, in whose pores the active cathode material is retained. A porous structure can be united with the massive solid electrolyte-separator into a unitary sinter composite of high ion conductivity, to which, if desired, there can also be joined on the anode side a porous sinter framework for receiving the alkali metal. The meltable active electrode materials are introduced by immersion into the porous portions of the sinter composite. The porous solid electrolyte structure can also be used advantageously as the separator system for cells with molten liquid electrodes, e.g. of the Na/S high temperature cell type.
