Battery of circular cell shape with central lithium anode and non-aqueous electrolytes. Galvanisches Element in Rundzellenform mit zentrisch angeordneter Lithium-Anode und nichtwaessrigem Elektrolyten

Abstract

The separation of such a cell situated between the negative and positive electrode is formed by a loose plastic vliess cut into a strip, which during assembly of the cells, is laid with central orientation on the open cell cup already provided with a circular cathode and filled with electrolyte and is pressed directly through the bar-shaped lithium electrode into the hollow space of the annular cathode, where it surrounds the lithium electrode as a compressed, closed sheath. Excess electrolyte flows into the sheath from the uncompressed top part of the separator vliess over the electrodes, to the extent that the lithium electrode is electrochemically dissolved and the expanding vliess maintaining contact with the lithium takes up liquid so that there is no interruption of ion conduction between the electrodes.
