FIG. 2 is a vertical cross-sectional view of a battery manufactured by the manufacturing method of the present invention, where 11 is a metal plate that also serves as a current collector for the positive electrode, 12 is an annular ceramic ring, 13 is a metal ring made of stainless steel, etc., and 14 is a metal plate that also serves as a current collector for the positive electrode. A positive electrode mixture mainly made of silver oxide, 15 a separator, 16 a negative electrode mixture made of oxidized zinc, cmO, sodium polyacrylate, etc., and 17 a metal plate that also serves as a current collector for the negative electrode. fl! in the above configuration! To explain the manufacturing method, a metal ring 13 is welded to a ceramic ring 12 using a silver soldering method, etc., and then it is placed on a metal plate 11 having approximately the same diameter as the outer diameter of the ceramic ring 12, and then The contact portion with the ceramic ring 12 is welded by silver brazing or the like. Thereafter, the positive electrode mixture 14, the separator 15, and the negative electrode mixture 16 are filled in the ceramic ring 12, and a 40% saline electrolyte is injected. After storing the battery elements, the metal plate 17 is placed and the metal plate 17
The periphery of the metal ring 13 and the abutting metal ring 13 are welded together by ring projection welding or the like.
