Abstract

PURPOSE:To raise reliability by interposing a sealing metal ring between a sealing ring and a case on anode, to relax mechanical strain, e.g., tortion, etc., imparted on cell. CONSTITUTION:A cup-like container with the hermetic sealed negative electrode terminal 21 is housed with the cathodic mixture 26 composed mainly of amalgamated zinc powder, the electrolyte-impregnated material 27, and an alkali electrolyte, and also the case 30 below the anode is housed with the anodic mixture 29 of silver oxide, etc. Then, the portion 23b to be welded of the cup-like container is facially welded to the portion 30a to be welded of the case 30 below the positive electrode and sealed to form a cell. The cup-like container is formed by welding the negative electrode terminal 21 of kovar alloy, etc., to the case 23 on the positive electrode with the sealing ring 22 of ceramic, etc., and the sealing metal ring 31 of kovar alloy, etc., having a sectional shape of L. Also, the inside of the container is provided with the annular insulated gasket 24 and the negative electrode current collector 25 is interposed between the cathodic mixture 26 and the negative electrode terminal 21.
