20150236336 | SEALED BATTERY MANUFACTURING METHOD, SEALING MEMBER FOR SEALED BATTERY, AND SEALED BATTERY - A sealing member includes a metal lid, an elastic shaft, a supporting protrusion, and a tip portion. The tip portion has an engaging portion larger in diameter than a liquid inlet. The shaft portion has a diameter smaller than that of the liquid inlet and a shaft length longer than the thickness of the circumferential edge portion of the liquid inlet. A sealed battery manufacturing method includes: a temporary sealing step of pressure-contacting the engaging portion to the circumferential edge portion; a degassing step of forming a communication path by pushing the tip portion to such an extent that the lid part does not make contact with a battery case and the tip portion is apart from the circumferential edge portion; and a final sealing step of pressing the tip portion until the lid part makes contact with the battery case, thereby sealing the liquid inlet. | 08-20-2015 |
