Abstract

PURPOSE:To prevent any short circuit resulting from the slack of the electrode group developing when a metallic negative terminal is used by fusing it to a current-collecting plate located at one end of the negative lithium electrode and then inserting a negative output terminal into the negative terminal before these parts are welded together. CONSTITUTION:A negative terminal 11 consisting of a metallic pipe is fused to a current-collecting nickel plate 9 located at one end of a negative lithium electrode 3 and then an electrode group 2 is wound around the negative terminal 11. The negative output terminal 8 of a battery lid 6 is inserted into the negative terminal 11 and fused to it to form a fused area 12 and then the thus formed body is placed in a can 1. Next, after the battery lid 6 and the can 1 are subjected to laser welding 13 and then a liquid electrolyte is poured through the opening of the negative output terminal 8, its opening is welded to completely seal the battery.
