た。Problems to be Solved by the Invention In recent years, the applications of sealed lead-acid batteries have expanded, and the demand for cylindrical batteries such as dry batteries and nickel-cadmium batteries has increased. Behind this is the problem of pollution caused by mercury, cadmium, etc., and it is expected that lead batteries with established recycling systems will be compatible with these batteries. For this purpose, it is important to make the device lightweight, small, and thin. It is possible to change the shape of a conventional synthetic resin battery case from a box shape to a cylindrical shape, but if the wall thickness is reduced to make it lighter, smaller, and thinner, the water content in the electrolyte will decrease,
There is a risk that the negative electrode plate will deteriorate significantly due to oxygen entering from the outside, and there is a limit to how thin the cylindrical type can be made.

After electrically connecting the ears of the electrode plate group including the positive electrode plate, negative electrode plate, and separator to the terminal by a method such as arc welding, or inserting a laminated film or sheet into a cylindrical shape, or Alternatively, after suspending the electrode plate group using a laminated film or sheet, heat weld the sides to form a cylindrical shape, and attach the cylindrical shape to the top and bottom lids with layers of the same type of material as the top and bottom lids facing both lids. It has a structure that is welded by methods such as ultrasonic welding.

The terminal 2 and the ear portion tta of the wound electrode plate group 11 are electrically connected by a method such as spot welding. After this electrode plate group is wrapped with a laminate film or sheet 4, the sides are heat welded, and the laminate film or sheet is welded to the synthetic resin top cover 1 and bottom cover 3 by a method such as ultrasonic welding. Therefore, the layer of the laminate film or sheet 4 in contact with the top lid 1 and the bottom lid 3 is preferably made of the same material as the top lid 1 and the bottom lid 3, and polypropylene, high-density polyethylene, etc. are suitable.
