description A zinc/air cell having thin walled cup shaped anode casing and cathode casing. The cell may be a button cell having an anode comprising zinc and a cathode disk, which may be catalytic, comprising manganese dioxide. The anode and cathode casings each have small wall thicknesses, preferably between 2 and 5 mil (0.0508 and 0.127 mm), desirably between about 2 and 3 mil (0.0508 and 0.0762 mm). The cathode disk is inserted and then punched into the cathode casing so that the disk is pressed towards the closed end of the cathode casing. This causes the cathode disk to expand radially between the cathode disk and inside surface of the cathode casing, reducing the chance of electrolyte leakage around the edge of the cathode disk. The diameter of the cathode disk is preferably between about 0.5 and 2.5 mil (0.0127 and 0.0635 mm) greater than the inside diameter of the cathode casing after the disk is punched into the cathode casing.
