ALKALINE DRY BATTERY AND PRESSURE ATTACHING METHOD OF ITS POSITIVE MIX

PROBLEM TO BE SOLVED: To make the thickness of a positive electrode container thin to increase the inner volume of a battery and prevent increase in contact resistance in an alkaline dry battery. SOLUTION: In the pressure attaching method of a positive mix to a positive electrode container 1, after the positive mix 2 is inserted into the positive electrode container 1, while the top surface of the positive mix 2 is pressed down with a punch 12, a core rod 11 having the diameter larger than the inner diameter of the positive mix 2 is inserted into the inner diameter of the positive mix 2 to attach the positive mix 2 to the positive electrode container 1 by the force in the radial direction. Since the force in the diameter direction acts, deformation of the container 1 is not produced unlike the conventional process, increase in contact resistance can be prevented, and the thickness of the positive electrode container 1 can be reduced to 0.200 mm or less.
