PURPOSE:To make a battery lightweighted and improve its lifetime and performance by winding a group of element by means of a hollow cylindrical body made of a flexible and acid-proof resin coat and the like, inserting it in a container, sealing pressed air in the cylindrical body, and pressurizing the group of element. CONSTITUTION:A group of element 1 is welded and assembled using a positive electrode post 2 and a negative electrode post 3 and is wound at arbitrary intervals by means of a hollow cylindrical body 4 made of a flexible and acid-proof resin coat and the like. Then, after the group of element 1 is inserted in a container 6, a storage battery is obtained by sealing pressed air and the like in the hollow cylindrical body 4 and tightly sealing the sealing entrance 5 of the hollow cylindrical body 4 so that the pressurization of the group of element 1 can be set to 5 to 20kg/dm<2>. As a result, when the group of element 1 is inserted in the container 6 or until an electrolyte is injected into the battery, the damage of both end plates of the group of element 1 caused by the physical and mechanical oscillation and shock, etc. can be prevented. Besides, when the electrolyte is injected, since the margin between the group of element 1 and the container partition wall is filled with the hollow cylindrical body 4, a great amount of the electrolyte can not be housed and the light weight of the battery can be achieved. |
