PROBLEM TO BE SOLVED: To provide a silver oxide battery having an excellent electric characteristic and a large capacity. SOLUTION: In a silver oxide battery in which a zinc-containing negative electrode mix 2 enclosed in a negative electrode cup 6 and a positive electrode mix 1 enclosed in a positive electrode can 3 are stacked with a separator 4 between them, silver oxide powders with an average particle size of not less than 10μm and not more than 5μm and with a bulk density of not less than 1.2g/cm<3> and not more than 1.7g/cm<3> are used in the positive electrode mix 1. The positive electrode mix 1 formed by mixing the silver oxide powders of the above size with a conductive material and a binder and molding them into a pellet shape is enclosed in the positive electrode can 3, the negative electrode mix 2 formed by mixing zinc in power form with a gelling agent and electrolytes and molding them into a pellet shape is enclosed in the negative electrode cup 6, and the positive electrode mix 1 and the negative electrode mix 2 are stacked with the separator 4 between them. Further, a solution of potassium hydroxide and a solution of sodium hydroxide that have high concentrations are added as the electrolytes, and the positive electrode can 3 and the negative electrode c&Egr;p 6 are caulked via a sealing gasket 5 to form the battery. |
