发明名称 SEALED BATTERY AND MANUFACTURING METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To provide a sealed battery in which the welding work is easy when sealing, the welding condition can be detected appropriately, and long term sealability can be maintained surely, and to provide a manufacturing method for the same.SOLUTION: A secondary battery is a sealed battery obtained by enclosing an electrode body and electrolyte in a battery case, and has a liquid injection port 25 penetrating the battery case, and a sealing plug 31 which seals the liquid injection port 25. The sealing plug 31 is formed by fixing an end-sealing plate 32 having a diameter larger than the opening diameter of the liquid injection port 25, and a sealing part 33 formed of an elastic body having a diameter smaller than that of the end-sealing plate 32 and having a crosslinking density of 1.00×10-1.00×10mol/cc. Whole circumference of the end-sealing plate 32 is sealed to the battery case by welding.
