PURPOSE: To provide a battery of high discharge performance, by inserting a molded anode together with an anode ring into a case and compressing the peripheral part of the anode to tightly fit it in the case but leave an uncompressed part in the center of the anode.
CONSTITUTION: To manufacture a molded anode 1, powder of AgO is molded and then dipped in a reducing solution so that a silver layer 4 is provided on the surface of the molded powder. The cylindrical part of a ring 2 is inserted in between the anode 1 and an inside wall. An upper die 5 for tightly fitting the molded anode 1 in a case 3 has a columnar shape. The central part of the face of the die 5 has a circular recess 5a of D in diameter and d in depth. The diameter D is smaller than that of a hole 2a. When the anode 1 is pressed, its peripheral part is compressed but its other part corresponding to the recess 5a of the die 5 remains substantially uncompressed. At the same time, the anode ring 2 is pressed into the anode 1. Since the silver layer 4a of the uncompressed part keeps an original porous structure, an electrolyte poured into the part in the following process is quickly absorbed into the anode 1.
