Abstract

PURPOSE:To suppress the generation of cracks in forming and permit mass production of thin type positive electrodes by pressing and molding integrally positive electrode mixed agent and the formed metal disc having a specific solid volume and a diameter and fabricating a cell, allowing the foamed metal side to contact with a separator. CONSTITUTION:A foamed metal plate 2 having the value of solid volume 1.43- 8.00mul/cm<2> which is obtained by dividing the surface density by the specific gravity of the metal is formed to have the diameter which corresponds to 94.0-99.4% of the inner diameter of a cell positive electrode can. Onto this metal plate 2, the positive electrode mixed agent 3 having silver oxide as active substance is fitted and compressed, and formed integrally to a positive electrode 1. A button type cell is fabricated by allowing the foamed metal plate 2 of the positive electrode 1 to contact with a separator. Therefore, the generation of fissures and cracks in forming the positive electrode 1 can be eliminated, and the mass production of thin type cells having the thickness for example of 0.6mm. or less is facilitated, and a cell having a large electric capacity and a small internal resistance can be obtained.
