    • A material for the positive electrode of a silver oxide battery is provided that increases the discharge capacity of the battery. The positive electrode material is a conductive composite oxide represented by the general formula AgxNiyO2, in which X/Y is greater than 1 and does not exceed 1.9, and by the general formula AgxNiyMzO2, in which M represents at least one of Cu and Bi, X/(Y+Z) is greater than 1 and does not exceed 1.9, and Z does not exceed 0.4. These conductive oxides contain almost no free Ag2O and have a crystal structure similar to that of AgNiO2. As a result, the excess Ag—Ni oxide is conductive and has a high discharge capacity.
    • 提供了用于氧化银电池的正极的材料,其增加了电池的放电容量。 正极材料是由通式为O x Y Y 2 O 2的通式表示的导电复合氧化物,其中X / Y大于 1,并且不超过1.9,并且通式为Ag x N 2 O x O 2 O 2,在 M表示Cu和Bi中的至少一种,X /(Y + Z)大于1且不超过1.9,Z不超过0.4。 这些导电氧化物几乎不含有游离的Ag 2 O,并且具有与AgNiO 2 O 2相似的晶体结构。 结果,过量的Ag-Ni氧化物是导电的并且具有高放电容量。

    • Alkaline battery silver oxide powder when soaked in a 50° C. KOH 40% aqueous solution for 24 hours experiences dissolution of Ag into the solution of 40 mg/L. Alkaline battery silver oxide powder exhibits substantially no Ag peak by X-ray diffraction even after soaking in a 50° C. KOH 40% aqueous solution for 72 hours. This powder has a crystallite size calculated from the half value breadth of the (111) plane peak by powder X-ray diffraction of greater than 250 Angstrom and equal to or less than 1000 Angstrom, particle diameter such that the average diameter of secondary particles is equal to or greater than 1 μm and equal to or less than 500 μm and that of primary particles forming the secondary particles is equal to or greater than 0.1 μm and equal to or less than 10.0 μm, and specific surface area of 5 m2/g or less.
