(DE3150702-C)      An electrochemical storage cell based on sodium and sulphur, includes an anode chamber, a cathode chamber and a sepg. solid electrolyte. The cathode chamber contains at least one cathode current collector, and a conducting matrix material. The cathode chamber has a strongly anisotropic felt material in it, whose fibres run parallel to the solid electrolyte. The felt is pref. soaked in a phenol resin dissolved in ethanol.    ADVANTAGE -   The cell is simple and economical to produce, and is reliable in operation. (6pp)c    (US4555846-A)      Electrochemical storage cell based on alkali metal and chalcogen utilises anisotropic C or graphite felt which is inserted into the cathode space. The felt is made of coked pitch fibre and its principal fibre direction parallel to the solid electrolyte. The felt is impregnated with a soln. of a duromer dissolved in a solvent, most of the duromer being in the region of the cathodic current collector. The duromer is subsequently carbonised at 500-1500 deg.C in the cathode space.    Pref. the soln. consists of a phenolic resin dissolved in ethanol which is impregnated into the felt after it is positioned in the cathode space.    ADVANTAGE -   The cell, which uses a sulphur electrode, has a high conductivity. (7pp)    (EP82492-B)      Process for the manufacture of an electrochemical storage cell (1) based on sodium and sulphur, having at least one anode space (5) and one cathode space (4) and an alkali metal ion-conducting solid electrolyte (3) separating the two spaces, an electron-conducting felt (11) being arranged in the cathode space (4) and being fixed to the cathode current collector (4B) via a carbonised resin, characterised in that at least one highly anisotropic felt (11) is inserted, with the main fibre direction parallel to the solid electrolyte (3), into the cathode space (4) and is impregnated with at least one dissolved thermosetting resin (12), and that then the major quantity of the thermosetting resin (12) is accumulated in the region of the cathodic current collector (4B) and the entire thermosetting resin (12) is then carbonised.
