Abstract
PURPOSE:To improve the heavy load characteristics of a dry battery and to prevent the internal short-circuit failure by pressing a carbon rod on the bottom of which a soft resin layer is formed into a zinc container in which positive compound is charged. CONSTITUTION:An adhesive or a coating of anti-electrolyte and electrically insulative such as epoxyresin is spread on the bottom 6 of a carbon rod 5 in heaped or flatened shape to form a soft resin layer 7. The carbon rod 6 is pressed into a zinc container 1, which is charged with a positive compound, until the resin layer 7 touches to the bottom of the zinc container spaced with an insulating bottom paper 2. Then, upper and bottom edges of an external container 15 are folded inwardly to seal. Using this fabricating method of a dry battery, only recesses are formed on the soft resin layer 7 and the insulating bottom paper 2 will not be broken even if carbon particles or coarse grains in the positive compound 4 attached on the surface of the resin layer 7 touch on the insulating bottom paper 2. Thus the carbon rod 5 will not connect to the zinc container 1 and the short-circuit failure is prevented.
