Abstract
PURPOSE:To enhance the liquid leakage resistance of an airtightly sealed battery by using as the solid adhesive of the airtightly sealing part, mixture of lead oxide and glycerol which is solidified due to its cross-linking reaction. CONSTITUTION:After generation elements 5-7 are installed in a positive can 1, a second member, the can 1 is sealed with a first member consisting of a metallic ring 2, a current collecting body 3 and an airtight solid adhesive 4 interposed between the ring 2 and the body 3. Next, the can 1 and the ring 2 are welded at a welding part 8 through a laser beam welding, thereby constituting an airtightly sealed battery. As the airtight solid adhesive 4, mixture of lead oxide and glycerol which is solidified through cross-linking reaction is used. For instance, lead oxide powder and glycerol are mixed in a ratio by weight of 5 to 1 before the mixture is kneaded into a mud-like mixture, and the mud-like mixture is packed between the ring 2 and the body 3 and is left to stand in a room so as to make it to be solidified.
