Abstract

PURPOSE:To obtain an alkaline battery having long storage life even if low amalgamat ed zinc negative electrode is used by covering the surface, in contact with a negative active material, of a negative current collector, and further covering with at least one element selected from a group of Cd, Ga. In, Tl, Pb. and Bi thereon. CONSTITUTION:The surface, in contact with a negative active material, of a negative current collector is covered with nickel and further covered with at least one element selected from a group of Cd, Ga, In, Tl, Pb, and Bi. The part, in contact with the negative active material, of the negative current collector is made of copper or brass, and the mercury on the surface of the negative current collector diffuses inward during storage and the mercury concentration on the surface of the current collector is lowered. The evolution of hydrogen gas caused by a local cell produced between the current collector and the negative zinc, and the evolution of hydrogen gas caused by the lack of the mercury content on the surface of the negative zinc, which is pro duced by the transfer of mercury from the zinc to the current collector, and the dissolu tion of the zinc into an alkaline electrolyte are prevented. Thereby, an alkaline battery having long storage life and capable of using low amalgamated zinc can be obtained.
