PURPOSE:To suppress the growth of dendritic zinc from metallic zinc at the initial stage of charge/discharge cycle by using zinc particles having mixed layers consisting of specific calcium compound and zinc oxide at the surfaces as an active material. CONSTITUTION:Zinc particles which have mixed layers consisting of at least one calcium compound, being selected from calcium hydroxide or calcium oxide, and zinc oxide at the surfaces are used as active material of a zinc pole. Hereby, calcium compounds turn out to exist dispersedly at the surfaces of the zinc particles and by the calcium compounds it can suppress the flow of zinc acid ions into electrolyte and prevent growth of dendritic zinc. |
