Abstract
A sintering device for the production of cupular solid electrolytes, which are used to separate anode and cathode compartments in sodium-sulphur cells, is in the form of a jacket tube and is produced from two or more metal oxides or metal hydroxides. The device and method avoid the disadvantages of the prior art sintering devices that are costly to manufacture and in most cases destroy the uniform distribution of the sodium within the soilid electrolyte material.
