Abstract

PURPOSE:To lengthen the preservation property and increase the discharge performance of a nonaqueous battery by dehydrating a manganese dioxide used for an active material by dielectric heating under a reduced pressure. CONSTITUTION:A collector 6 made of titanium is welded on a case 1 made of a stainless steel. A positive electrode 5 made of manganess dioxide is placed on the collector 6, before a separator 7 and a liquid-holding material 8 are placed on the positive electrode 5, in that order. A grid 3 is placed between a sealing plate 2 and a lithium negative-electrode 4, and these three are pressed and welded, before the negative electrode is placed on the liquid-holding material 8. At the same time, a gasket 9 is interposed between the case 1 and the sealing plate 2 to hermetically seal the battery, thus constituting a nonaqueous-electrolyte battery. The manganese dioxide used for the positive electrode 5 is prepared by dehydrating a hydrated substance like electrolytic manganese-dioxide under a reduced pressure, by subjecting the hydrated substance to dielectric heating, for example, by means of an electronic-oven microwave to remove the bound water. Here, a natural manganese dioxide or the like can be used for the hydrated substance instead of using electrolytic manganese-dioxide, and especially, the gamma-phase compound is preferred.
