PURPOSE:To obtain a battery having excellent performance by containing chemically synthesized manganese dioxide having gamma type crystal obtained by carrying out heat treatment on manganese oxide obtained by roasting manganese sulfate as its main ingredient and silver oxide (I), and using a positive electrode flux in which content of the former is a specific weight percentage. CONSTITUTION:Chemically synthesized manganese dioxide and flaky graphite are combined into silver oxide (I) so that volume of the chemically synthesized manganese dioxide becomes, for example, 5, 10 or 15% and volume of the flaky graphite becomes 5 % is in a positive electrode flux, and they are mixed together so that the uniform positive electrode flux 1 can be obtained. Furthermore, the positive electrode flux 1 is used so that a a silver oxide battery can be assembled. A positive electrode vessel 2 filled with the positive electrode flux 1, a separator 3, a zinc negative electrode 4 and an opening sealing plate 5 are provided, and a gasket is embedded in its vicinity, and the opening edge of the positive electrode vessel 2 is bent inward and pressurized so that it can be sealed up. Here, the positive electrode flux, which contains chemically synthesized manganese dioxide powder having gamma type crystal obtained by carrying out acid treatment on manganese oxide obtained by roasting manganese sulfate as its main ingredient and silver oxide (I) powder, and in which content of the manganese dioxide is 5-15wt.% is used. |
