Abstract
PURPOSE:To reduce an internal resistance increase in storage by using as a positive active material; divarent silver oxide powder having a lead dioxide layer obtained by treating it in an alkaline solution of lead nitrate on the powder surface. CONSTITUTION:Divalent silver oxide powder having a lead dioxide layer obtained by treating it in an alkaline solution on the powder surface is used as an active material of a positive electrode 1. Lead exists in forms of lead ion and lead hydroxide which is a colloidal precipitate in an alkaline solution of lead nitrate. When divalent silver oxide powder is put into this solution, the reaction occurs on the divalent silver oxide surface, and lead dioxide layer is formed on the surface of the divalent silver oxide powder. Because lead dioxide is the oxide of the highest oxidation state and has excellent oxidation resistance and good conductivity, a cell which uses the divalent silver oxide powder obtained by forming lead dioxide layer on the powder surface as the positive active material in the positive electrode 1 after press-molding, has small internal resistance and can reduce an internal resistance increase during storage.
