Secondary battery on cell with dual electrode. [German Patent]

Abstract

The barrier layer penetrable to alkali metal ions is in ion-conducting contact with the melted anode alkali metal on the one side and, on the other side, in ion-conducting contact with a cathode reactant of liquid electrolyte. The electrolyte is electrochemically reversibly reactive with the anode reaction component and consists of a mixture of melted polysulfide salts of the alkali metal and molten sulfur when the cell is partly discharged. The improvement on the secondary battery, according to the invention, involves electrode devices containing first and second electrodes. The first electrode is designed for battery charge; it is installed in the first section of the cathodic reaction zone and is wetted to a greater extent by the melted polysulfide than by molten sulfur. The secondary electrode is designed for battery discharge; it is installed in a second section of the cathodic reaction zone and is wetted to a greater extent by molten sulfur than by melted polysulfide.
