PURPOSE:To obtain an electrode of a cell using mass-producible copper molybdenum sulfide at a low cost by reducing a solid precursor obtd. from ammonium thiomolybdate and copper halide under heating and using produced copper molybdenum sulfide as a base. CONSTITUTION:Ammonium thiomolybdate and copper halide are mixed and brought into a reaction in an org. solvent to form a precursor and the org. solvent as a medium is removed by evaporation. The resulting solid precursor is reduced under heating in an atmosphere of gaseous hydrogen to produce copper molybdenum sulfide and an electrode of a cell based on the sulfide is obtd. The copper molybdenum sulfide means copper molybdenum sulfide having so-called chevrel phase and is a compd. represented by the formula (where x is 1.5-4 and y is 0-0.4). Ammonium tetrathiomolybdate is preferably used as the ammonium thiomolybdate because oxygen is prevented from entering the product. |
