Abstract
The present application discloses a battery comprising: an electrode assembly formed by alternately superposing each of at least two electrode plates having one polarity and at least one electrode plate having the other polarity with each of separator layers therebetween; a battery vessel for housing the electrode assembly and constituted by a metallic outer case and a metallic closure cover joined to the metallic outer case; a collector rod having a flange located inside the closure cover, the collector rod passing through a through-bore formed in the closure cover, through an insulating member so that one end of the collector rod is projected from the closure cover; and a metallic ring fitted to the projected portion of the collector rod with an insulating member disposed between the metallic ring and the closure cover. According to the battery of the present invention, the head of the projected portion of the collector rod is crushed and this crushed portion is embedded in a concave portion formed in the top surface of the ring. According to the battery of the present invention, said electrode plates having said one polarity are electrically connected to the battery vessel, and …
