Title: Galvanic primary cells having a positive sulphur electrode
IPC: H01M4/06
Filed: 1972-12-29
Abstract: 1411270 Organic electrolyte cell with sulphur cathode VARTA AG 29 Dec 1972 [30 Dec 1971] 60105/72 Heading H1B A primary cell comprises a negative electrode of a light metal, preferably lithium, an organic proton-free electrolyte solvent containing a conducting salt, and a positive electrode containing sulphur and an electrically-conductive material, the sulphur being insoluble in carbon disulphide. In one method of making the positive electrode, crystalline sulphur is subjected to heating, quenching and extraction with carbon disulphide solvent to leave a residue of sulphur which is insoluble in carbon disulphide, mixing an electrically conductive material with the insoluble sulphur powder and bringing the mixture on to a support under high pressure. Another method comprises mixing crystalline sulphur powder and a pulverent, electrically conductive material, pressing the mixture on to a support, heating the electrode to at least 140‹ C., quenching the heated electrode in a cold liquid, and extracting the quenched electrode with carbon disulphide solvent such that the residual sulphur in the electrode is insoluble in carbon disulphide. The electrically-conductive material may be a metal powder and/or graphite and/or carbon black. The positive electrode may also include a stabilizer for the sulphur, the stabilizer being a compound which readily evolves halogen, e.g. halogen-amides, benzyl halides and alkenyl halides. The positive electrode may also include a bonding agent, e.g. polyisobutylene. Preferred electrolytes are (a) propylene carbonate containing boron trifluoride or (b) butyrolactone containing potassium hexafluorophosphate and boron trifluoride.
