Abstract
Method for the manufacture of an electrochemical storage cell of the sodium and sulfur type, with at least one anode space and one cathode space as well as an alkali ion conducting solid electrolyte separating the two, where at least one cathodic current collector and one electron-conducting matrix material are arranged in the cathode space. The invention is characterized by the features that in the cathode space at least one strongly anisotropic felt is inserted with the principal fiber direction parallel to the solid electrolyte; the felt is impregnated with at least one dissolved duromer; and thereupon a larger amount of the duromer is collected in the vicinity of the cathodic current collector; and the duromer is subsequently coked.
