PURPOSE:To obtain a thin type battery that hardly generates gas without using mercury by using a perchlorate zinc aqueous solution as an electrolytic solution as an electrolyte solution and the zinc alloy containing Ga, In, and Pb as a negative electrode active material. CONSTITUTION:Manganese dioxide that is a positive electrode active material 2 is arranged on the conductive plastic film surface of a positive electrode collection body 1 laminated with a conductive plastic film and aluminum. In addition, the zinc that is a negative electrode active material 3 is arranged on a negative electrode collection body 6 made of the same materials as the collection body 1. A separator 4 impregnated with an electrolytic solution is inserted between them and its periphery is tightly sealed with an insulating sealing frame 5. In addition, as the electrolytic solution, for example, perchlorate zinc aqueous solution whose molar ratio is 1.0-2.5M and as the electrolytic solution, for example, zinc alloy containing Ga 0.5-0.20%, In 0.01-0.04%, and Pb 0.1-0.3% is used. As a result, the generation of gas can sharply be suppressed. |
