<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a lithium ion secondary battery which enables the simplification of a manufacturing process of a lithium ion secondary battery, and enables the release of hydrogen generated in a battery by a simple method.SOLUTION: A method for manufacturing a lithium ion secondary battery comprises the steps of: injecting an electrolyte into a battery container 101 through an electrolyte inlet 102 of the battery container; and thereafter sealing the electrolyte inlet 102 with a selectively hydrogen-permeable film 11. Especially, the selectively hydrogen-permeable film 11 serving to seal the electrolyte inlet 102 is arranged as an air permeable member 1 held by a frame 10. Further, the air permeable member 1 is integrally formed so that a protection sheet material 21 is disposed on each side of the selectively hydrogen-permeable film 11.</p> |
