PURPOSE:To minimize the initial open-curcuit voltage of an organic electrolyte battery by using a liquid organic electrolyte containing an alkali metal iodide and to enable the open-curcuit voltage of the battery to be set to a desired level by controlling the content of the alkali metal iodide. CONSTITUTION:After a nonwoven polypropylene fabric used as a separator is placed on a negative lithium electrode, a plastic gasket is attached to the separator. Next, a liquid organic electrolyte containing an alkali metal iodide is poured onto the separator and then a manganese dioxide pellet is placed on the separator. After that, the thus formed body is sealed in a positive and a negative can be caulking, thereby assembling a flat organic electrolyte battery with a diameter of 20mm and a thickness of 2.45mm. The liquid organic electrolyte is prepared by dissolving a 0.8X10<-1>mol/l concentration of lithium iodide in a 1mol/l propylene carbonate solution of lithium perchlorate. The open circuit voltage of this battery is 3.12V immediately after its assembly and increases to 3.20V after one-week storage in an atmosphere maintained at 60 deg.C. But, it does not increase to a level over 3.20V even when the battery is stored for over one month. |
