Abstract

PURPOSE:To improve the leak-proof performance of a dry battery, by forming a film of an adhesive or coating of anti-electrolyte cylindrically on the outside surface except the bottom surface of a zinc container. CONSTITUTION:A positive compound 4 on the center of which a positive carbon rod 3 is inlaid via a separator 2 is filled in a negative zinc container 1, and a polyamide film 14 comprising an adhesive or a coating of anti-electrolyte is formed cylindrically on the outside surface of the zinc container 1 covering a part of the outside surface 13 between a level (A) slightly above the upper surface of the positive compound 4 and the bottom end (B). Then a cylinder of insulating paper and an external container are provided on the outside of the film to form a battery. Thus oxygen will not enter from the external if the zinc container 1 is locally corroded to form micro-pores through discharge reaction, and micro-pores will not extend resulting in prevention of the leakage of electrolyte effectively.
